Why Winter Skincare Starts from Within

How to Protect, Restore and Strengthen Your Skin in Colder Months

As temperatures drop and central heating kicks in, your skin begins to face one of its biggest annual challenges: winter.

Dry air, sharp winds, and low humidity levels can strip your skin of its natural moisture, disrupt the barrier function, and accelerate signs of ageing. It’s a time when skin becomes more vulnerable, reactive, and in need of deep support, both on the surface and at a cellular level.

While moisturisers and serums play their part, true skin resilience starts from within. In this guide, we explore why winter skincare needs to go deeper, and how a holistic approach to skin nutrition can help repair, restore and future-proof your skin for the season ahead.

The Science of Winter Skin Stress

During winter, several physiological shifts occur in the skin:

• Trans epidermal Water Loss (TEWL) increases due to low humidity and harsh winds, leading to dehydration and tightness

• Sebum production naturally slows down, reducing the skin’s ability to retain moisture

• Skin barrier function becomes compromised, making it more prone to irritation, sensitivity and flaking

• Circulation to the skin surface can be reduced in colder temperatures, meaning fewer nutrients and oxygen are delivered to the skin cells

All of this contributes to a dull, dry complexion and for many, the return of redness, eczema, or breakouts.

“Winter can be ageing for the skin, not just in how it looks, but how it behaves on a cellular level.” – Katie Lennick, Founder

Why Surface-Level Solutions Aren’t Enough

While a rich moisturiser can help create a barrier against the elements, it doesn't solve the underlying issues like nutrient deficiencies, inflammation, oxidative stress, or weakened collagen structures.

Topical skincare has its limits. The skin is designed to keep things out. That’s why focusing on internal support through smart supplementation can offer results that are not just faster, but longer-lasting.

Skin Health at the Cellular Level

Healthy skin function is dependent on a consistent supply of vitamins, minerals, antioxidants, and structural proteins, many of which are depleted more quickly during winter.

Key nutrients involved in skin repair and resilience include:

• Vitamin C: Vital for collagen production and neutralising free radical damage caused by environmental stress

• Hyaluronic Acid and Silica: Support deep hydration and skin elasticity from within

• Zinc and Selenium: Reduce inflammation and support skin cell turnover

• Hydrolysed Collagen: Delivers amino acids directly used to rebuild skin firmness and elasticity

• Astaxanthin: A powerful antioxidant shown to protect skin against UV and oxidative damage, especially important in winter sun conditions

• Vitamin D3: Increasingly deficient in winter months, yet essential for immune regulation and skin health

Clinical research shows that oral supplementation with collagen peptides and antioxidants can improve skin hydration, elasticity, and wrinkle depth over 8 to 12 weeks.
