Winter presents unique challenges for mature skin, but with the right approach, you can maintain a healthy, radiant complexion throughout the season. This comprehensive guide explores the science behind winter skin challenges and provides practical solutions specifically tailored for mature skin.

Understanding the Science of Winter Skin

The combination of aging and harsh winter conditions creates distinctive challenges for mature skin. As we age, our skin naturally produces less collagen and elastin, making it more susceptible to environmental stressors. Winter's low humidity and cold temperatures can exacerbate these effects, leading to increased dryness, sensitivity, and visible signs of aging.

Light and Skin Health: A Hidden Connection

Winter's shorter days affect skin health more profoundly than many realize. Reduced sunlight exposure disrupts several crucial biological processes:

• Vitamin D synthesis decreases significantly during winter months, affecting the skin's ability to repair and regenerate. This vitamin plays a vital role in maintaining healthy skin barrier function and supporting collagen production. Without adequate levels, skin may become more prone to damage and show accelerated signs of aging.

• Melatonin production, which regulates our circadian rhythm, becomes disrupted. This hormone serves as a powerful antioxidant, protecting skin cells from environmental damage. When production decreases during winter months, skin becomes more vulnerable to oxidative stress.

The True Impact of Indoor Heating

While indoor heating provides comfort from the cold, it creates an artificially dry environment that can be particularly harsh on mature skin. This low-humidity environment increases transepidermal water loss (TEWL). Think of TEWL as your skin's moisture escape route. In winter, it's like having multiple tiny leaks in a water pipe, causing constant moisture drainage and leading to:

• More pronounced fine lines and wrinkles.
• Compromised skin barrier function.
• Increased sensitivity and irritation.
• Potential exacerbation of existing skin conditions like rosacea and eczema.

Essential Winter Skincare Strategies

1. Cleansing Without Compromise

The foundation of winter skincare begins with proper cleansing practices. For mature skin, implementing specific protocols for both daily skincare and showering helps maintain optimal skin health during harsh winter conditions.

Facial Cleansing Protocol

Selecting appropriate cleansers forms the cornerstone of effective winter skincare. Cream or oil-based formulations prove particularly beneficial during winter months, as they effectively remove impurities while preserving the skin's natural moisture barrier. Look for products containing nourishing ingredients such as jojoba oil, marula oil, or phytoceramides.

Limit cleansing to twice daily to prevent over-washing and stripping the skin of its natural moisturizing factors. Use lukewarm water, as excessive heat can strip essential oils from the skin. After cleansing, apply a hydrating essence while the skin is still damp, followed by a nutrient-rich occlusive serum to lock in moisture.

Shower Protocol for Skin Protection

Hot water exposure during showering presents a significant challenge during winter months, as it can increase trans-epidermal water loss (TEWL). Applying a thin layer of jojoba oil (or a similar gentle, non-comedogenic oil) before showering creates a protective barrier that helps retain moisture during bathing.

2. Layer Skincare for Maximum Hydration

Mature skin requires a sophisticated approach to hydration, especially during winter:

• First Layer: Begin with a hydrating treatment mist containing humectants like hyaluronic acid, aloe, and glycerin. Apply to slightly damp skin to maximize absorption.

• Second Layer: Follow with a concentrated micro-serum or essence containing multiple molecular weights of hyaluronic acid to ensure hydration reaches different layers of the skin.

• Final Layer: Seal in moisture with a rich oil serum or balm containing both emollient and occlusive ingredients. Look for products with phytoceramides, peptides, and nourishing whole-plant oils to restore the skin's natural protective barrier and prevent moisture from escaping.

3. Additional Barrier Protection Strategies

Create a comprehensive strategy to protect against environmental stressors in your home:

• Use a humidifier in your bedroom and office to maintain optimal dermal humidity levels (40-60%).

• Limit blue light exposure from electronic devices, as it increases reactive oxygen species (ROS) that contribute to premature skin aging. If you must work in front of a screen for long periods, consider blue light glasses and wear sunscreen for additional protection.

• Always apply a non-toxic broad-spectrum SPF 30 or higher, even indoors and on cloudy days. Look for formulations containing additional antioxidants like vitamin C or niacinamide.

Advanced Treatment Protocols

How Facial Mists Can Help

Facial mists go beyond a refreshing spritz—they’re a versatile skincare staple that can transform how your skin looks and feels. Here’s why they’re a winter essential:

1. Instant Hydration

When your skin starts to feel parched, a facial mist delivers an immediate surge of moisture. This is especially useful on cold, dry days or when you’re on the go.

2. Replenishes Dry, Flaky Skin

Dryness and flakiness are common in winter, but hydrating facial mists can help restore your skin’s moisture levels. They work wonders when layered with other products to lock in hydration and keep skin smooth and supple.

3. Comforts Reactive, Sensitive Skin

Winter skin often becomes more reactive, but a soothing facial mist—like our Neroli Hydrasoothe Treatment Mist—can help calm redness and irritation. Ingredients such as neroli, aloe vera, and chamomile provide instant relief for angry, stressed skin.

4. Refreshes Makeup

Makeup tends to crack and settle into dry patches when skin is dehydrated. A quick spritz of facial mist not only revives your makeup but also enhances its longevity, leaving you with a dewy, fresh-faced look.

5. Preps Skin for Maximum Absorption

Hydrating mists help prepare your skin to absorb serums, essences, and moisturizers more effectively. Applying mist before these steps creates a hydrated base, ensuring your products penetrate more deeply for optimal results.

For the ultimate winter skincare indulgence, try layering our Neroli Hydrasoothe Treatment Mist with Aspen Dew Illuminating Essence and The Alpine Phytonutrient Serum or Purist Delicate Skin Serum. Together, these products create a comforting ritual designed to restore balance, vitality, and radiance to winter-stressed skin.

Crafting a Holistic Winter Skincare Ritual

To keep your skin healthy and luminous all winter, adopt this easy yet luxurious routine:

Step 1: Gentle Cleansing

Start with a gentle, hydrating oil cleanser to remove impurities without stripping the skin. Choose a formula that nourishes while maintaining your skin’s natural oils.

Step 2: First Mist

Spritz your face with Neroli Hydrasoothe Treatment Mist. This step balances your skin’s pH, refreshes, and preps it for the next steps in your skincare routine.

Step 3: Essence

Apply Aspen Dew Illuminating Essence to brighten, firm, and deeply hydrate your skin. An essence provides a layer of nourishment that enhances the benefits of subsequent products.

Step 4: Serum

Massage a few drops of The Alpine Phytonutrient Serum or Purist Delicate Skin Serum into your skin. These serums address specific concerns such as dryness, fine lines, and dullness while delivering long-lasting hydration.

Step 5: Final Mist

Seal in all the benefits with another spritz of facial mist. This final step helps set your makeup, lock in hydration, and protect your skin throughout the day.

PRO TIP: Look for facial mists containing hydrating ingredients like hyaluronic acid, aloe vera, and fresh botanical extracts like aspen bark. These ingredients work together to nourish, soothe, and refresh your skin.

What to Look for in a Winter Facial Mist

Not all facial mists are created equal. When selecting one, look for key ingredients that address hydration, soothing, and nourishment:

• Hyaluronic Acid: A hydration powerhouse that attracts and retains moisture.
• Aloe Vera: Calms and soothes irritation while providing lightweight hydration.
• Botanical Extracts: Ingredients like neroli, chamomile, or aspen bark provide antioxidant benefits and help reduce redness and sensitivity. 

At TellurideGlow, we love ingredients that tell a story—ones that connect plant wisdom, science, and sustainable beauty. Among these, jojoba oil ( Simmondsia Chinensis) stands out as an unrivaled natural marvel. From its origins in the arid deserts of the American Southwest to its transformative role in skincare today, jojoba is as fascinating as it is effective. Let’s explore the rich history, science, and skincare benefits of this extraordinary botanical, and why it remains a hero ingredient in all of our serums.

A Gift from the Desert

The Origins of Jojoba Jojoba (pronounced ho-HO-ba) is native to the Sonoran Desert in the southwestern United States and northwestern Mexico.

This resilient shrub thrives in one of the most extreme environments on earth, withstanding intense heat, freezing cold, and long droughts, making it a remarkable desert survivor.

The secret to its survival lies in its remarkable adaptability:

• Deep Tap Roots: Jojoba plants develop roots that extend up to 15 meters underground, reaching water reserves deep within desert soils.

• Moisture-Holding Molecules: Jojoba's living tissues contain a unique wax ester molecule that helps retain moisture. Remarkably, this molecule is identical to the wax esters found in human skin, a trait that makes jojoba so powerful for skincare.

• Natural Shield: The plant’s waxy coating protects it from losing moisture and shields it from solar radiation, a trait that mirrors how jojoba can help care for our skin.

Jojoba’s History and Cultivation Jojoba has been used for centuries by Native Americans, who relied on its seeds as both a food source and a remedy for skin and scalp health. Jesuit priests documented how tribes toasted jojoba seeds, ground them into salves, and applied the waxy substance to heal wounds, burns, and other skin irritations. It was even consumed to ease stomach ailments and aid childbirth.

Much later, in the 1970s, the global demand for sperm whale oil—once used in cosmetics and industrial lubricants—was halted due to environmental concerns. As industry searched for a solution, scientists rediscovered jojoba oil.  They found that jojoba was nearly chemically identical to sperm whale oil, making it the perfect ethical and sustainable replacement.

This remarkable discovery sparked a flurry of jojoba cultivation in Arizona, Peru, Australia, Israel and beyond. Despite this early rush, jojoba farming remains relatively rare, and most plants today are just 1-2 generations removed from their wild ancestors. Because jojoba shrubs can take up to 7-8 years to reach maturity, care and patience are required to grow jojoba sustainably.

The Unique Composition of Jojoba Oil

Jojoba oil is often referred to as an oil, but it’s actually a liquid wax, unlike any other plant-derived ingredient. It's the only plant in the world that produces liquid wax esters that are identical to those found in human skin. Here’s a breakdown of its unique composition:

• 50% Liquid Wax Esters: These wax esters are bioidentical to the sebum produced by human skin, allowing jojoba oil to deeply penetrate and easily into the dermis without irritation.

• 30% Protein Content: The seed contains a high concentration of proteins, adding to its nourishing properties.

• Moisture Retention: Just as jojoba wax protects the plant from the desert’s harsh sun, it can help prevent moisture loss and enhance hydration in skin.

Jojoba Oil Skin Benefits

The Most Biocompatible Oil in Nature

Jojoba oil’s effectiveness lies in its biocompatibility with human skin.  Here’s how it works its magic:

• Mimics Human Sebum: Jojoba oil is bioidentical to our skin’s natural oils. This allows it to absorb easily, balance oil production, and leave skin conditioned without feeling greasy.

• Balances All Skin Types: Whether your skin is dry, oily, or a combination of both, jojoba adapts. It helps regulate sebum production—hydrating dry areas while signaling oily skin to produce less oil.

• Restores Skin Barrier Health: Jojoba oil supports the skin's microbiome, strengthens the skin barrier, and protects against environmental stressors.

• Non-Comedogenic: Rated low on the comedogenic scale, jojoba oil won’t clog pores, making it perfect for acne-prone skin. Its ability to dissolve sebum blockages in pores also helps clear blemish prone skin.

• Fights Premature Aging: Starting around age 20, our bodies produce less sebum, leading to dehydrated skin, fine lines, and wrinkles. By supplementing skin with jojoba’s wax esters, you can help plump up skin, improve elasticity, and slow the signs of aging.

The Therapeutic Benefits of Jojoba Oil

• Non-Allergenic: Jojoba is safe for people with nut allergies, gluten intolerance, or sensitive skin. It’s even used in massage therapy for medically compromised individuals, such as on oncology patients.

• Anti-Inflammatory Properties: Jojoba oil can help address redness and inflammation caused by conditions like eczema, psoriasis, and sunburn.

• Supports Collagen Synthesis: Studies show that jojoba oil can stimulate mRNA production in skin cells, promoting collagen and hyaluronic acid synthesis and improving elasticity.

• Antioxidant Stability: Naturally rich in Vitamin E, jojoba oil fights free radicals and protects against oxidative stress. Its low triglyceride content means it resists oxidation, extending the shelf life of skincare products.

Sustainability in Every Drop

Jojoba is as good for the planet as it is for your skin:

• Eco-Friendly Farming: Jojoba grows on marginal land, areas unsuitable for agriculture, reducing competition with food crops.

• Minimal Processing: Jojoba beans are mechanically pressed under high pressure in a cold press. This process extracts the oil from the seeds without the use of heat or chemicals, preserving its purity and environmental integrity.

• A Sustainable Replacement: Its role as an alternative to sperm whale oil and its status as a low water usage crop highlights its contribution to ethical and sustainable beauty practices.

Why We Love Jojoba

At TellurideGlow, jojoba oil plays a starring role in our formulations, particularly in The Purist Delicate Skin and Alpine Phytonurtient Serums. By combining jojoba with powerhouse alpine botanicals like Arctic cloudberry, rosehip, and Himalayan sea buckthorn, we create products that balance, nourish, and hydrate your skin—all while honoring sustainability and luxury.

From its desert origins to its transformative benefits, jojoba oil represents the perfect union of nature and science. Jojoba oil is a cornerstone of radiant, healthy skin.

Have you ever wondered how to maximize the results of your skincare routine, especially during the challenging winter months when dry, reactive skin and fine lines become more pronounced? Layering products, starting with a well-formulated essence, can significantly enhance their effectiveness and create a truly radiant complexion.

Why layering is a winter skincare must

Think of your skin like a well-tended garden. There's the topsoil, where seeds are planted, but beneath that are layers of earth that retain moisture and deliver nutrients to the roots. Each layer plays a crucial role in the garden's overall health. This principle applies directly to your skincare routine.

Our Aspen Dew Illuminating Essence is like creating that vital first layer of moisture-rich soil. Formulated with micro-molecular hyaluronic acid, soothing aloe, plant-derived ceramides, and other powerful botanicals, it not only moisturizes the skin’s surface but also actively delivers deep hydration to parched skin, creating a plump, healthy foundation and optimizing your skin to receive the full benefits of subsequent products.

This perfectly hydrated base allows subsequent products, like our  Alpine Phytonutrient Serum, to penetrate deeply, delivering their benefits to all layers of the skin, just as nutrients travel through the soil to the plant’s roots. Without this foundational hydration, even the best serums can only nourish the surface.

Struggling with dry, painful winter skin? See how our two-step ritual helped one customer find relief:

"I’m amazed at my skin during this frigid weather! My skin never hurts anymore. In the past, I have hydrated to the max, “moisturized” and supplemented my body during the winter but still had that “winter face feeling.”

TellurideGlow’s Winter Two-Step Ritual for Deep Winter Hydration

Step One: Hydrate & Prep

Our Aspen Dew Illuminating Essence, infused with hydrating actives like hyaluronic acid and soothing aloe, deeply hydrates to soften, quench, and plump dry winter skin, creating the perfect base for optimal absorption of the serum's nourishing ingredients.

Step Two: Nourish & Protect

Our Alpine Phytonutrient Serum locks in the hydration from the essence while further strengthening your lipid barrier with nutrient-rich oils and adaptogens to protect and restore your skin.

The result? Skin that is deeply hydrated, nourished, and glowing—even in the harshest winter conditions.

Why Hydration + Lipid Barrier Protection Work Better Together

Hydration attracts water to the skin. But without a protective layer to hold that hydration in, water quickly evaporates—leaving your skin drier than before. That’s why layering is so important:

First, Aspen Dew delivers a surge of hydration to thirsty skin. Then, The Alpine locks in this hydration with nutrient-rich oils, providing superior hydration and lasting protection.

Real Results, Effortlessly

Winter doesn’t have to mean dry, tight, flaky skin. With just two simple steps, you can give your skin everything it needs to stay hydrated, healthy, and radiant.

You may prefer flip flops and beaches, but knowing these surprising health benefits may help you appreciate colder temperatures.

Healthy reasons to embrace the cold

Weight loss

Our bodies dip into the fat supply for fuel to keep warm. One study published in The Journal of Clinical Investigation found that exposure to cold temperatures (not accompanied by shivering) can activate brown fat metabolism, so it may help burn calories. And shivering can be good, too, as it also stimulates the burning of fat. A study published in the journal Cell Metabolism found that shivering stimulates the secretion of irisin, a hormone that induces fat burning. Apparently, just 15 minutes spent shivering in a cold environment has the same effect as exercising for an hour. (Word of caution below). The flip side is that cold temperatures may increase your appetite.

Better sleep

The latest existing research suggests that the ideal temperature for the best sleep should be somewhere between 60 to 67 degrees Fahrenheit, and you might burn more calories, too. Your body’s core temp naturally drops when you’re trying to sleep and the process is much faster in winter.

Allergy relief

Pollen counts are virtually nonexistent in cold and snowy weather, so if you suffer from outdoor allergies, you may get a break! Of course, there are other indoor allergens in wintertime you should consider, such as mold and dust mites, but for the most part, you’ll get a bit of a reprieve.

Brain boost

Studies show that colder temperatures help people think clearly. What’s more, other research shows that people tackle more cognitive problems in the winter than in the summer, because summer temps use more glucose that’s needed for mental processes.

Inflammation

Cold air acts like a natural ice pack to decrease inflammation, so you might get some relief from less swollen and puffy joints in winter.

Techniques like cryotherapy involve brief exposure to extremely cold temperatures (often below -200°F) in a specialized chamber. While research is ongoing, proponents suggest cryotherapy may offer several benefits. These include reducing muscle soreness and inflammation by constricting blood vessels and decreasing nerve activity, potentially aiding in faster recovery after exercise. Some also report pain relief for conditions like arthritis and improved skin conditions due to increased blood flow after the treatment.

Immune benefits

Cold weather kicks your immune system into gear and fights infections more effectively. Studies have shown that the human immune system can be activated when exposed to the cold, and this enhances someone’s ability to fight infections. 

Practices like the Wim Hof Method combine specific breathing techniques, cold exposure (such as cold showers or ice baths), and mindset/meditation. Advocates suggest the Wim Hof Method can enhance the immune system by influencing the autonomic nervous system and reducing inflammation. It's also believed to improve mental focus and mood through the release of endorphins and other neurochemicals.

Mood enhancer

As your body works harder to stay warm while exercising outdoors, endorphins are released-- those feel-good hormones--and your mood is naturally lifted.

Please Note: Of course, extremely cold weather can be dangerous, and you should exercise caution. Take a look at these must-read tips for plummeting temperatures or these severe weather tips from Antartica.

Skin benefits of cold

The good news

You know that hot water can dry the skin, but did you know that cold weather increases blood circulation by constraining blood vessels in the skin? This reduces the likelihood of puffy eyes and facial swelling.

Exposure to cool weather also tightens the pores of your skin and invigorates your face. Think clear, bright eyes and rosy cheeks. Plus, you tend to produce less oil and sebum in the winter, so you may have fewer breakouts.

The bad news

Multiple elements can victimize your complexion, especially in high altitudes. Wind, sun, cold, heat and dryness create the perfect situation for chapped, depleted skin and can promote and contribute to aging. Click here for our winter skincare guide.

TellurideGlow embraces the cold

Powerful survivalist plants

We use high ratios of premium alpine botanicals because they produce powerful antioxidants, phytonutrients, and UV defenses to thrive in extremely cold climates. The air is cleaner, the soil undisturbed, and powerful secondary metabolites are produced to ward off pests and environmental aggression with some of the most beneficial plant composition on the planet.

TellurideGlow taps into these adaptive strategies with whole plant, certified organic formulas to nourish and protect against dehydration, free radical damage, sensitivities, and signs of premature aging.

Cold processing 

Virgin and raw ingredients are well known for their nutritional benefits. Our premium botanical ingredients are abundant in bioactive anti-oxidants, plant-derived nutrients, essential fatty acids, vitamins, amino acids and minerals, so we seek out cold pressed ingredients to deliver better skin nutrition to restore and replenish the skin.

Cold formulating

Fresh botanical ingredients can lose much of their potency when heated, so to maintain the integrity of our raw ingredients we manufacture our whole plant formulas with cold technology, blending with extremely low to no heat during manufacturing.

Cold storage

Many warehouses are not climate controlled, so we searched until we found the right one to ensure our fresh ingredients are not compromised as temperatures rise.

Hyaluronic acid is a naturally occurring substance in our bodies. In skincare, it's prized for its ability to hold up to 1,000 times its weight in water, giving skin a soft, plump texture and a more even tone. It can also improve the appearance of fine lines and wrinkles and is generally gentle on the skin barrier.

However, not all hyaluronic acid molecules are created equal. There are different sizes, and these variations significantly impact how the ingredient interacts with your skin. Hyaluronic acid is often listed on ingredient labels as sodium hyaluronate (INCI = Sodium Hyaluronate), which doesn't specify the molecular size. Therefore, understanding the difference between these sizes is crucial for achieving your desired results.

Think of hyaluronic acid as a big drink of water for your skin. But the way that water is delivered depends on the size of the molecules. We can broadly categorize them by molecular weight: low and high.

High Molecular Weight Hyaluronic Acid

High molecular weight hyaluronic acid molecules are larger and cannot penetrate the skin barrier. Instead, they form a film on the skin's surface, binding with keratin upon evaporation. This film provides surface hydration, improves elasticity, and has anti-inflammatory and soothing properties. However, because it sits on the surface, this film is easily washed away, offering only short-term benefits.

• Pros: Surface hydration, improved elasticity, anti-inflammatory, soothing.
• Cons: Short-term effects, easily washed away, no deep penetration.

Low Molecular Weight Hyaluronic Acid

Low molecular weight hyaluronic acid molecules are smaller and can penetrate deeper into the skin, reaching the connective tissue. Here, they bind water to skin cells, infusing all layers of the skin with moisture. This deeper hydration contributes to firmer, more supple skin and can visibly reduce wrinkles. The key advantage is that the moisture is stored more sustainably within the skin, providing longer-lasting effects. However, it's important that low molecular weight HA is used in proper ratios, as improper concentrations can potentially irritate the skin.

• Pros: Deep hydration, improved firmness and elasticity, visible wrinkle reduction, longer-lasting effects.
• Cons: Potential for irritation if used in improper concentrations.

Myths About Hyaluronic Acid: What Most People Get Wrong

Hyaluronic acid is often considered a “miracle ingredient” in skincare, and while it truly offers impressive benefits, there are several misconceptions surrounding its use. These misunderstandings can lead to suboptimal results or even frustration with products that contain HA. Here’s what you need to know to ensure you’re using HA effectively and seeing the results you deserve.

1. All hyaluronic acid is the same

One of the biggest misconceptions is that all hyaluronic acid is created equal, but in truth, its molecular size determines how it works and what it can do for your skin. Many products simply list "sodium hyaluronate" or "hyaluronic acid" on their ingredient label, leaving customers in the dark about the molecular weight of the HA being used.

• Why This Matters:
  High molecular weight HA sits on the surface of your skin, forming a temporary hydrating film that feels silky but lacks deeper, long-term impact. In contrast, low molecular weight HA penetrates into the deeper layers of the skin, replenishing hydration where it’s needed most and supporting long-lasting moisture retention.
  However, many brands avoid specifying molecular weights in their marketing materials because high molecular weight HA provides an immediate plumping effect, which can be visually convincing in the short term but doesn’t support skin health over time.

• Takeaway for You:
  If your goal is to achieve long-term hydration, elasticity, and improved skin texture, look for products like Telluride Glow's Aspen Dew Illuminating Essence, that use low molecular weight HA in proper concentrations to sustain moisture levels beneath the surface.

2. More hyaluronic acid = better results

Another common myth is that products with higher concentrations of hyaluronic acid will deliver better results. While this might seem logical, it’s not how HA works.

• The Science Behind It:
  Hyaluronic acid has the unique ability to bind up to 1,000 times its weight in water, but it doesn’t act as a self-contained moisturizer. Instead, it draws moisture from its surrounding environment—either from the air or, in dry conditions, from the deeper layers of your skin. When used in overly high concentrations or without proper occlusion (a sealing layer like a serum or oil), HA can actually dehydrate the skin by pulling moisture out and allowing it to evaporate.
  Additionally, HA that is too concentrated can sometimes disrupt the skin’s barrier, leading to irritation, especially for individuals with sensitive or compromised skin.

• Takeaway for You:
  Rather than seeking the highest concentration of HA, focus on formulations where HA is balanced with complementary ingredients and designed to work in harmony with your skin’s natural processes. Proper formulation matters more than percentage claims on a label.

3. Hyaluronic acid works alone

Many people believe that hyaluronic acid is a one-stop solution for hydration, but this is another oversimplification. While HA is excellent at attracting water, it doesn’t necessarily lock that water into the skin on its own.

• The Science Behind It:
  Without a sealing layer, the moisture HA attracts to your skin can quickly evaporate, leaving your skin feeling drier than before. This process is called transepidermal water loss (TEWL). In fact, HA needs to be layered with occlusive or emollient ingredients—like oils or rich serums—to create a protective barrier that prevents moisture from escaping.
  Think of HA as the water your skin needs, while occlusives are the lid on the container that keeps that water from evaporating. This combination ensures your skin stays plump, hydrated, and radiant throughout the day.

• Takeaway for You:
  For best results, follow your HA application with an occlusive product, like Telluride Glow’s Alpine Phytonutrient Serum or The Purist Delicate Skin Serum, to lock in the moisture and amplify the benefits of hyaluronic acid. This two-step hydration strategy is especially important in dry climates or during colder months when environmental factors can exacerbate dehydration.

4. Hyaluronic acid is universally gentle

While hyaluronic acid is often praised as a safe, non-irritating ingredient suitable for all skin types, even this claim has its caveats. Though rare, HA can cause irritation or dryness when used improperly.

• The Science Behind It:
  Low molecular weight HA, in particular, is known to penetrate deeper into the skin. While this is beneficial for hydration, it can occasionally irritate individuals with highly sensitive or reactive skin if used in excessive concentrations or without balancing ingredients. High molecular weight HA, on the other hand, is less likely to cause irritation because it remains on the surface.
  Another source of irritation can come from how HA is formulated. If the product includes unnecessary fillers, synthetic fragrances, or drying alcohols alongside the HA, these can counteract its hydrating effects and irritate the skin barrier.

• Takeaway for You:
  Always check not just for the type of HA used, but also for the overall formulation. Products like Telluride Glow’s Aspen Dew Illuminating Essence are specifically designed with low molecular weight HA in carefully calibrated concentrations to deliver results without compromising the skin’s health. And, as always, follow up with a moisture-sealing layer to reduce any chance of irritation.

5. Hyaluronic acid can replace moisturizer

One of the most persistent myths is that using a hyaluronic acid serum eliminates the need for a moisturizer. This misunderstanding can lead to underwhelming results for customers who stop moisturizing altogether after introducing HA into their routine.

• The Science Behind It:
  HA is a humectant, meaning it attracts water to itself. However, it doesn’t add fats or oils to the skin, which are necessary for supporting the lipid barrier and preventing water from escaping. Skipping a moisturizer, especially in colder or drier climates, can leave your skin vulnerable to dehydration despite using HA.
  Additionally, hyaluronic acid works synergistically with moisturizers and emollients, meaning the combined effect is greater than either product alone.

• Takeaway for You:
  Think of HA as the hydration hero, and your moisturizer or serum as the partner that helps lock in that hydration for the long haul. To maximize results, follow your HA with an occlusive layer, such as Telluride Glow’s Alpine Phytonutrient Serum, which not only seals in moisture but also adds nutrient-rich oils to nourish your skin.

6. Hyaluronic acid always comes from natural sources

Finally, it’s important to note that while HA is naturally present in the human body, not all HA used in skincare products is sourced naturally. In fact, much of the HA on the market today is synthetically derived or produced via bacterial fermentation.

• Why This Matters:
  While synthetic HA is effective, it’s important to choose formulations that prioritize purity and safety, particularly if you have sensitive skin or are concerned about environmental sustainability. Some formulations may include synthetic additives or stabilizers that compromise the integrity of the product.

• Takeaway for You:
  When choosing an HA product, consider brands like Telluride Glow that are transparent about their ingredient sourcing and formulations. Knowing how and where your HA is sourced can ensure you’re getting the safest, most effective hydration for your skin.

Our formulas 

At Telluride Glow, our first priority is to formulate effective and safe products. We use a low molecular weight in our Aspen Dew Illuminating Essence to give you lasting results, with proper ratios to ensure a non-irritating formula. Some brands typically use a combination of high molecular weight as it shows immediate effects to convince the buyer of its effectiveness. However, the effectiveness isn’t long lasting if your goal is to support your skin in the long run.

Best way to apply a hyaluronic acid serum

Though hyaluronic acid can attract and retain moisture, it doesn’t necessarily keep that moisture from evaporating over time. That’s why it’s important to maximize the benefits by adding occlusive products after the essence, like our Alpine Phytonutrient Serum or The Purist Delicate Skin Serum. These serums seal in the moisture drawn into skin by the hyaluronic acid, and the two work together to ensure skin is both hydrated and stays that way.

Fun fact

Tremella mushroom Tremella fuciformis, is a key ingredient in our Snow Rose Recovery Mask for water retention. Tremella's particle sizes are actually smaller than those of HA, giving Tremella the ability to hold 5 times more water than hyaluronic acid!

Hyaluronic acid is a powerful tool in your skincare arsenal, but it’s not a magic bullet.

By understanding how molecular weight affects its function, how to properly layer it with other products, and why thoughtful formulations matter, you can make informed decisions that deliver real results.

Telluride Glow’s HA-based products are crafted with transparency, effectiveness, and long-term skin health in mind—because we believe in giving your skin the hydration it deserves, backed by science and nature.

As our skin evolves over time, it requires tailored care focused on hydration, firmness, and protection from environmental stressors.

Aspen Dew Illuminating Essence addresses these needs by serving as a multi-functional skincare product that replaces multiple items in a routine, making it ideal for anyone seeking simplicity without compromising on effectiveness.

Let’s dive into each benefit and explore how Aspen Dew meets your skin’s needs with powerful ingredients and thoughtful formulations. Plus, discover additional tips for enhancing your overall skin health.

1. Facial Toner: Prep and Balance Skin pH

• Why Toners Matter: Toners play a key role in balancing the skin’s pH after cleansing, which can be disrupted by tap water and harsh cleansers. A balanced pH is essential for skin resilience and moisture retention.
• Ingredient Spotlight: Aloe vera is rich in polysaccharides that soothe and hydrate, while rose oil offers mild antibacterial properties and a refreshing effect.
• Pro Tip: For best results, apply Aspen Dew on slightly damp skin to lock in additional moisture. This enhances the absorption of the following ingredients and preps your skin for hydration.
• Lifestyle Tip: Consider reducing the number of cleansing steps to prevent over-stripping natural oils. Gentle, non-foaming cleansers or oil cleansers are especially beneficial for mature skin.

2. Retinol Alternative: Gentle Cell Renewal

• Why Retinol Alternatives are Important: Retinoids promote cell turnover, helping improve texture and tone. However, they can sometimes cause dryness and sensitivity, particularly in skin that’s prone to dryness.
• Ingredient Spotlight: Dew bean extract is a plant-based retinol alternative that supports smooth, fresh-looking skin without irritation.
• Pro Tip: Incorporate Aspen Dew into your nighttime routine to take advantage of your skin’s natural repair cycle, allowing dew bean to work effectively while you sleep.
• Lifestyle Tip: Nourish your skin from the inside out by eating foods rich in Vitamin A and beta-carotene, like sweet potatoes and carrots, to support healthy skin renewal.

3. Wrinkle Cream: Support Firmness & Reduce Fine Lines

• Pro Tip: Apply Aspen Dew on slightly damp skin, followed by a moisturizer to seal in the hyaluronic acid’s moisture-boosting benefits.
• Lifestyle Tip: Stay hydrated throughout the day by aiming for at least 8 glasses of water. Adding hydrating fruits like watermelon and cucumbers to your diet can also benefit your skin.

7. Niacinamide Serum: Enhance Barrier Function & Even Skin Tone

• Why Niacinamide is Essential: Niacinamide, or Vitamin B3, strengthens the skin barrier, reducing dullness, redness, and visible signs of environmental stress.
• Ingredient Spotlight: Niacinamide in Aspen Dew promotes elasticity and supports ceramide production, improving moisture retention and tone.
• Pro Tip: Use Aspen Dew daily to reap the cumulative benefits of niacinamide, helping to reduce the appearance of enlarged pores and uneven tone.
• Lifestyle Tip: Add niacinamide-rich foods like nuts, seeds, and whole grains to your diet to support your skin’s barrier function from within.

8. Facial Mist: Refresh & Hydrate Skin 

• Why Mists are Beneficial: Mists provide quick hydration boosts and help lock in the benefits of other products when layered.
• Ingredient Spotlight: Phytoceramides help strengthen the skin’s moisture barrier, while aloe vera and sodium hyaluronate keep skin soft and refreshed.
• Pro Tip: Use Aspen Dew throughout the day to replenish moisture, especially in dry environments or after sun exposure to cool skin.
• Lifestyle Tip: Keep a facial mist at your desk or carry it with you to rehydrate skin on the go, which is especially helpful in dry indoor spaces like office buildings and in airplane cabins.

9. Ceramide Serum: Strengthen & Restore Skin Barrier Health

• Why Ceramides are Important: Ceramides are lipids that occur naturally in the skin barrier, crucial for retaining moisture and protecting against environmental damage.
• Ingredient Spotlight: Glycosphingolipids, or plant-derived ceramides, enhance resilience and moisture retention, fortifying the skin barrier.
• Pro Tip: For optimal barrier protection, apply Aspen Dew as the first layer of hydration, followed by an oil serum to reinforce the barrier and lock in moisture.
• Lifestyle Tip: Consuming healthy fats, like avocado and omega-3-rich fish, supports your skin’s natural lipid levels, which can help keep your skin’s barrier strong.

10. Calming Elixir: Reduce Redness

• Why Calming Ingredients are Needed: With age, skin can become more sensitive and prone to redness. Calming ingredients help soothe inflammation and provide relief.
• Ingredient Spotlight: Aspen bark extract is both anti-inflammatory and antiseptic, while aloe vera and edelweiss calm and nourish sensitive skin.
• Pro Tip: Use Aspen Dew as a post-sun treatment to cool and calm reddened skin. Apply chilled for an extra-soothing effect.
• Lifestyle Tip: Avoid extreme temperatures on your skin, like hot water or direct sun exposure. Incorporate anti-inflammatory foods like turmeric and ginger to calm your skin from the inside out.

Streamline Your Routine with Aspen Dew

Aspen Dew Illuminating Essence is more than just a single skincare product— it’s a  10-in-1 facial treatment, designed to nourish, protect, and revitalize your skin.

By incorporating Aspen Dew into your daily routine, you’re not only saving time but also ensuring that your skin receives comprehensive care to stay resilient, radiant, and healthy.

For those looking to simplify their skincare regimen while maintaining a luminous, refreshed appearance, Aspen Dew Illuminating Essence offers a convenient, powerful alternative that delivers exceptional results in a single bottle.

Aspen, scientifically known as Populus tremuloides, and colloquially referred to as the quaking aspen for its distinctive fluttering leaves, is more than just an aesthetically pleasing deciduous tree native to North America.

Beyond its visual charm and the timber's valued durability and disease resistance, aspen harbors potent phytonutrients that offer a myriad of benefits for skin health.

Aspen bark is a phytonutrient powerhouse

The resilience of aspen trees, capable of thriving in harsh high-altitude environments, is largely attributable to their rich content of polyphenols and alkaloids. These compounds not only enable the aspen to fend off predators and diseases but also imbue it with remarkable longevity. Such phytonutrients are what make aspen bark extract a remarkabkle ingredient for skincare, providing significant anti-microbial, anti-oxidant, and anti-inflammatory benefits.

The historical & medicinal significance of aspen bark

Historically, aspen has been revered for its medicinal properties. Indigenous peoples of North America utilized it for treating a variety of conditions, from fever and skin burns to respiratory ailments.

The bark, in particular, was noted for its healing effects on wounds and chilblains, as well as its analgesic and anti-inflammatory properties, offering relief from back pain and potentially mitigating gastric ulcers.

Smoothing and Softening Effects

Aspen bark is a treasure trove of salicin, a precursor to salicylic acid, which acts as a gentle exfoliator.

By promoting the shedding of dead skin cells, salicin helps to smooth, soften, and brighten the skin, enhancing texture, diminishing fine lines, and revitalizing the complexion.

Ideal for sensitive skin

Due to its non-irritant nature, aspen bark extract is well-suited for sensitive skin types. It serves as a natural preservative, offering a safer alternative to traditional parabens while reducing the potential for skin irritation.

Anti-inflammatory properties

The blend of salicin and polyphenols in aspen bark extract provides significant anti-inflammatory effects. This can be particularly beneficial for calming reactive or irritated skin, with antioxidants helping to soothe the epidermis by combating free radicals and inflammation.

Potent antioxidant activity

Aspen bark extract's high phytonutrient content makes it a powerful antioxidant. Polyphenols protect the skin's structural proteins, such as collagen and elastin, from oxidative damage. This helps to preserve skin integrity and combating signs of premature aging.

Incorporating aspen bark into your skincare routine

Leveraging the power of aspen bark extract in skincare products, like our Aspen Dew Illuminating Essence, can significantly enhance skin health.

Its unique ability to smooth, soften, and calm, makes it an invaluable ingredient for anyone looking to restore balance and brightness to their complexion.

With October being Breast Cancer Awareness Month, and because breast cancer remains one of the leading health concerns for women worldwide, we wanted to take a moment to dive into some of the specific chemicals in skincare products that have been linked to breast cancer.

Research increasingly points to the potential role of endocrine disruptors—chemicals that can interfere with our hormone systems—as contributors to breast cancer risk. While these chemicals are pervasive in our environment, their presence in skincare and cosmetic products is of particular concern due to our direct and frequent exposure to them. 

What are endocrine disruptors?

Endocrine disruptors are chemicals that mimic the hormone estrogen and can interfere with the normal function of other hormones in the body. This estrogenic activity may lead to an increased risk of breast cancer, as it can promote the growth of hormone-receptor-positive breast cancer cells and disrupt immune system function.

By being aware of potential endocrine disruptors and educating ourselves about these chemicals we can make safer choices for our health.

Below is a list of endocrine disruptors most commonly found in skincare products and their potential effects on the endocrine system. Print it out and take it with you next time you go shopping for beauty products so you know what ingredients to avoid.

6 Endocrine Disruptors to Avoid

1. Parabens

Parabens are known to mimic estrogen by binding to estrogen receptors on cells (1.). This activity can potentially contribute to the growth of hormone-receptor-positive breast tumors.

Ingredient Names: Butylparaben, propylparaben, isobutylparaben, methylparaben.

Found in: Shampoos, conditioners, lotions, face cleansers.

2. Phthalates

Phthalates have been shown to interfere with the hormone system and are linked to reproductive abnormalities (2.).

Ingredient Names: DEHP, DBP, DEP (among others); however, they can sometimes simply be listed as "fragrance,” these are synthetic fragrances.

Found in: Perfumes, moisturizers, eye shadows, nail polishes, shampoos, conditioners.

3. Synthetic Colors

Some synthetic colors are derived from coal tar, which may contain heavy metal salts that deposit toxins onto the skin, causing skin sensitivity and irritation (3.). While direct links between synthetic colors and breast cancer aren't fully established, any toxin that affects the skin and potentially the endocrine system deserves scrutiny.

Ingredient Names: Listed as "FD&C" or "D&C" followed by a color and a number (e.g., FD&C Red No. 6).

Found in: Hair dyes, eye shadows, eyeliners, lipsticks.

4. Synthetic Fragrances

Many chemicals that make up synthetic fragrances come from petrochemicals, which can interfere with the body's endocrine system (4.) and possibly contribute to an increased risk of breast cancer.

Ingredient Names: Often vaguely labeled as "fragrance" or "parfum".

Found in: Nearly all cosmetic and beauty products, from deodorants to lotions.

5. Sodium Lauryl Sulfate (SLS)

Sodium Lauryl Sulfate, also called SLS, has potential endocrine-disrupting effects, with some studies pointing to its ability to mimic hormones(5.).

Ingredient Names: Sodium lauryl sulfate, sodium dodecyl sulfate.

Found in:  Shampoos, body washes, hand soaps, toothpaste.

6. Benzophenone

Benzophenones can mimic the hormone estrogen and may interfere with the function of other hormones, potentially promoting the growth of hormone-receptor-positive breast cancer cells (6).

Ingredient Names: Benzophenone, Benzophenone-1 (BP-1), Benzophenone-2 (BP-2), Benzophenone-3 (Oxybenzone), Benzophenone-4 (BP-4), Sulisobenzone.

Found in: Sunscreens, nail polishes, lip balms, hair sprays, shampoos, fragrances, and lotions.

The Path Forward

Awareness is the first step to prevention. By understanding the potential risks associated with these common ingredients, we can make informed decisions about the products we use daily. Opting for alternatives labeled as "free from" these chemicals or choosing organic, natural products can be safer routes to follow.

The Purist Delicate Skin Serum is our #1 choice for restoring health and promoting calm to a compromised skin barrier. Lightweight and free of fragrance allergens, essential oils, gluten, alcohol, and nuts, this velvety serum is the ultimate beauty potion to restore balance to irritated skin while fighting environmental aggression.

100% of the ingredients are from organic farming, wild-harvested, and/or natural sources, and free from harmful chemicals, preservatives, artificial colors, or fragrances.

Remember that the duration and frequency of exposure, along with individual susceptibilities, play a significant role in determining potential outcomes. It's essential to balance concern with pragmatism and do your best choose products you are educated about.
