When temperatures drop and days grow shorter, sunscreen often gets pushed to the back of our minds and of our skincare routine. However, protecting your skin from the sun’s harmful rays is just as important during the winter as it is during the summer. While the sun may feel weaker in cooler months, UV radiation is present year-round and can cause significant damage to your skin if left unchecked.
The sun emits two types of ultraviolet rays that impact the skin: UVA and UVB. While UVB rays, responsible for sunburns, are less intense in the winter, UVA rays remain constant throughout the year. UVA rays penetrate deep into the skin, contributing to premature aging, wrinkles and increasing the risk of skin cancer. Even on cloudy days, up to 80% of UV rays can pass through clouds, making sunscreen a daily essential.
Winter activities like skiing or snowboarding can amplify your exposure to UV radiation. Snow reflects up to 80% of the sun’s rays, essentially doubling your UV exposure. Additionally, high altitudes, where many winter sports take place, come with thinner atmospheres, allowing more UV radiation to reach the skin.
Using sunscreen daily is one of the simplest, yet most effective, ways to protect your skin from UV damage. Dermatologists recommend using a broad-spectrum sunscreen with an SPF of at least 30 to shield against both UVA and UVB rays. Apply it to all exposed skin, including your face, neck, ears and hands—areas often overlooked in winter.
Besides UV protection, many sunscreens contain moisturizing ingredients that help combat winter dryness. Opt for formulas that include hydrating components like hyaluronic acid or glycerin to maintain your skin’s moisture barrier.
Incorporating sunscreen into your morning routine ensures consistent protection. Apply it 15–30 minutes before heading outdoors and reapply every two hours, especially if you’re active or sweating.
Protecting your skin isn’t seasonal. The harmful effects of UV rays accumulate over time, regardless of the season. By wearing sunscreen daily—even in winter—you can prevent premature aging, reduce your risk of skin cancer and maintain healthy, radiant skin year-round. Remember, your skin is always worth the extra care.
