UV protection during winter

When we think about UV protection, summer heat usually comes to mind first. However, in reality, it is just as important during the winter months. Winter brings us fewer sunny days, but UV rays can still have a harmful impact on the skin because they are present throughout the year.

There are 3 categories of UV rays, UVA, UVB, and UVC, however, UVC rays are absorbed in the atmosphere before reaching the Earth. According to research by the World Health Organization, the other two types of UV rays affect the skin.

Rays that are present throughout the whole year, regardless of temperature, are UVA rays. They penetrate through clouds and fog, as well as through glass and other reflecting surfaces, such as windows. They penetrate deep skin layers, causing premature aging, loss of skin elasticity, and wrinkles, and they are present wherever there is sunlight.

UVB rays act on the upper surface of the skin and they make skin sunburns. Their intensity varies throughout the year. During the winter they are weaker, but they increase risk at high altitudes or in environments with reflective surfaces like snow, which can reflect up to 80% of UV rays and amplify exposure.

Why Is UV Protection important during winter, and how can we protect our skin?

UV protection is important during winter, especially at high altitudes and during winter sports, as exposure to UV rays increases without us even realizing it because of the cold. The consequences can be sunburns, early skin aging, hyperpigmentation, allergic reactions, and so on.

That is why skin protection is necessary when using creams with a broad spectrum of protection (UVA and UVB) and which also contain SPF. Products that contain added moisturizing have more benefits during winter, as skin tends to become drier and less hydrated.

Regular use of UV protection is a very important step in skincare. The protection cream should be applied 15–30 minutes before going outside and applied again every 2–3 hours, especially if we are spending time outside. When applying sunscreen, don’t forget to cover the neck, ears, and hands, which are often left unprotected.

Don’t forget about lip protection, because lips are constantly exposed to wind and cold during winter which causes drying. Using a lip balm with SPF will protect your lips and maintain their hydration.

Regular use of UV protection during the winter will prevent sunburns and premature skin aging but will also reduce the risk of hyperpigmentation, dryness, and other serious skin conditions. Thoughtful and long-term proper skin care will help to maintain a healthy, youthful appearance and preserve elasticity during the coldest time of the year.
