During the winter months in the Kocaeli and Izmit region — particularly from December through February — the skin faces significant stress: cold air and strong winds outdoors, and the drying effect of central heating indoors. This dual assault weakens the skin barrier, triggering dryness, itching, flaking and eczema flare-ups. A proper winter care protocol can prevent this damage, and the season simultaneously represents the optimal window for medical aesthetic treatments.
Factors Affecting the Skin in Winter: A Dermatological Perspective
- Increased TEWL (Transepidermal Water Loss): Low ambient humidity (10–20% outdoors) causes the skin to lose its own moisture more rapidly.
- Ceramide depletion: Skin exposed to cold produces fewer ceramides, which form the lipid barrier.
- Central heating: Indoor humidity can drop to 20–30%; the ideal range is 40–60%.
- Hot shower habits: Prolonged exposure to hot water strips the skin's natural oils and damages the barrier.
- Wind: Convective heat loss and mechanical irritation compromise barrier integrity.
- Pallor: A lower UV index reduces melanin stimulation, making the complexion appear duller.
Winter vs Summer Routine Comparison
| Step | Summer Routine | Winter Routine | Why the Change? |
|---|---|---|---|
| Cleanser | Light gel/foam | Cream-based, moisturising formula | To preserve barrier lipids |
| Toner/Essence | Light acidic water-based | Hyaluronic acid-based | To increase moisture-retention capacity |
| Moisturiser | Light gel or fluid | Rich cream or occlusive balm | Occlusion needed to reduce TEWL |
| AHA (glycolic/lactic) | Continue (low concentration) | Continue — actually the ideal period | Less UV → lower PIH risk |
| Retinoid | Continue, SPF essential | Continue — more comfortable use | Lower winter UV → reduced sun-sensitivity concern |
| SPF | SPF 50+ mandatory | SPF 30+ mandatory (every day) | Glass does not filter UVA; UVA is active year-round |
Ideal Winter Moisturiser Ingredient Combination
When choosing a winter moisturiser, the three-layer hydration principle should be observed:
- Humectants (moisture attractors): Hyaluronic acid, glycerin, panthenol — draw moisture from the atmosphere and the dermis.
- Emollients (barrier supporters): Ceramides 1, 3 and 6; niacinamide; plant oils — repair the lipid matrix.
- Occlusives (moisture sealers): Squalane, beeswax, shea butter, dimethicone — physically reduce TEWL.
In winter, formulations combining all three categories are preferred. Hyaluronic acid alone (a humectant) can actually draw moisture from the dermis in dry conditions, so using it without an occlusive is insufficient in winter — it must always be sealed with an occlusive layer.
Central Heating and Indoor Humidity: Why Does Room Humidity Matter?
In a centrally heated room, indoor humidity can fall to 20–30%. Even in coastal cities like Kocaeli, this presents a real problem. Ideal indoor humidity: 40–60%. Humidifiers can be used to maintain this range; they are especially critical in rooms containing infants or individuals with atopic dermatitis. Cleaning the humidifier filter regularly prevents the growth of bacteria and mould.
Lip and Hand Care: The Most Neglected Areas in Winter
Lips: Lips contain no sebaceous glands and are entirely dependent on external moisturisation. To prevent chapping in winter, a lanolin- or shea butter-based lip balm should be applied throughout the day. Licking the lips — although it provides temporary relief — causes saliva to evaporate and leads to further cracking.
Hands: Hands suffer the most damage in winter due to frequent washing and cold air. An emollient-rich hand cream should be applied after every wash; at night, an intensive moisturiser or occlusive glove protocol (glove occlusion) is recommended. Hand creams containing 5–10% urea are an ideal choice, providing both keratolytic and moisturising effects.
SPF in Winter: The "No Sun in Winter" Misconception
One of the most common winter skin care mistakes is putting sunscreen away. However:
- UVA rays are active year-round — clouds do not filter UVA.
- Glass does not filter UVA — UVA exposure occurs even inside a car or sitting near an office window.
- Snow reflects UV by up to 80% in winter (especially critical for skiing and hiking).
SPF 30 broad-spectrum is sufficient in winter. Creamy, moisturising formulations provide both hydration and UV protection, making them ideal for the winter months.
Winter: The Golden Window for Medical Aesthetics
Winter months are the most suitable season for many medical aesthetic treatments:
- Chemical peels: With low UV exposure, the risk of post-inflammatory hyperpigmentation (PIH) is significantly reduced; winter is the ideal window for medium-to-deep peels.
- Fractional laser: Minimal sun exposure during the healing period minimises the risk of pigmentation.
- Pigmentation treatments: Without the sun that causes pigmentation in summer, reaching summer-targeted goals is easier.
- PRP and mesotherapy: Can be performed in any season; combinations that support the skin barrier are especially recommended in winter.
Eczema and Psoriasis: Managing Flare-Ups in Winter
Atopic dermatitis (eczema) and psoriasis frequently flare in winter. Winter skin care is even more critical for these patients:
- Ceramide-based barrier-repair moisturiser at least twice daily
- Frequency and duration of washing should be minimised
- Wool and synthetic fabrics should not come into direct contact with skin
- Avoid radiators and fireplace smoke
- A winter-preparation consultation with a dermatologist is recommended
Virtuana Clinic Winter Skin Protocol: Izmit/Kocaeli
At Virtuana Clinic, we offer a dedicated "Winter Skin Assessment" for patients during the winter months. This assessment includes Corneometer-based hydration measurement, barrier function analysis and a customised product-and-treatment plan for the season. You can leave the clinic with a clinician-approved winter skin kit tailored to the cold and windy winter conditions of Kocaeli.
Frequently Asked Questions
Why does my skin look duller and more lifeless in winter? A lower UV index reduces melanin stimulation, and barrier damage contributes to a lacklustre complexion. Regular exfoliation (a light AHA 1–2 times per week) and consistent moisturisation can restore radiance.
Do I still need a moisturiser if I have oily skin in winter? Yes. Oily skin is also affected by TEWL. However, an oil-free, water-based moisturiser or a lightweight ceramide gel should be chosen; heavy occlusives should be avoided.
Is it safer to use retinoids in winter? Retinoids increase UV sensitivity; with lower UV levels in winter, it is a more suitable starting period. However, SPF use should be continued throughout winter as well.
