The skin is exposed to increased stress by outdoor activities, cold, windy weather, the drier air of the heated, warm apartment, large temperature differences, opting for hot baths and showers and hand wash with hot water. The skin dries out sooner, it becomes tense, cracked and itchy because its lipid and water content declines. In subzero temperatures, blood vessels become narrower, skin blood flow deteriorates, the metabolism and nutrient uptake of the cells slows down, the excretion of waste products is also slower, sweat and sebaceous glands decline in activity and secretion, the protective layer or barrier of the skin is also damaged. The skin can be regenerated with oily, soap-free shower gels, richer textured lipid-rich body lotions; choose oilier face creams. The use of make-up also provides a protective layer for the skin outdoors. You should not forget about proper fluid intake during the colder months; this can improve the quality and hydration of the skin.
The harmful effects of UV rays occur in winter as well; while shorter-wavelength, so called UVB rays increase the risk of skin cancer by damaging DNA in the skin cells, longer-wavelength UVA rays are responsible for skin aging. Think about sun protection even in winter; it is especially important for winter sports enthusiasts to use high-factor sunscreen lotions and lipsticks, as their skin is exposed to higher UV radiation levels from the reflection of the snow and they can get sunburned easily.
Do not expect vitamin D supplementation from solariums, it is preferable to take vitamins and check vitamin D level with a simple blood test.
When outdoors, wear a warm cap, a scarf and gloves, when indoors, use humidifiers; choose oilier cosmetics, apply cream on the hands and lips several times a day, and choose a cooler shower and a soap-free shower gel instead of a hot bath.
