When temperatures drop and the sky turns gray, sunscreen is often the first step in a skincare routine to disappear—but it shouldn’t be. Even in winter, UV rays remain strong enough to cause long-term skin damage, accelerate aging, and increase the risk of skin cancer. It’s easy to assume you’re safe when the sun feels weaker or is hidden behind clouds, but UV rays still penetrate through overcast skies. Sun protection is a year-round essential.
Winter also brings a unique challenge many people underestimate: sun reflecting off snow. Fresh snow can reflect UV radiation back onto your skin, increasing your exposure without you realizing it.
Here are the key reasons you shouldn’t ditch sunscreen during the winter months, no matter how chilly or cloudy it gets.

1. UV Rays Don’t Go Away in Cold Weather
The temperature may drop, but UV radiation stays strong year-round. UVA rays are responsible for premature aging and deeper skin damage, and they penetrate the skin in every season and can reach you even when the sun feels weak.
2. Clouds Don’t Block Most UV Radiation
Winter often brings overcast skies, but clouds only filter out about 20 percent of UV rays. That means up to 80 percent still reach your skin, causing invisible damage even when you don’t see or feel direct sunlight.
3. Snow Reflects UV Rays Back at You
Snow is highly reflective, bouncing UV radiation back toward your face. This double exposure is especially risky if you’re skiing, snowboarding, or even just walking outside on a bright winter day.
4. Winter Activities Increase Sun Exposure
Outdoor winter sports and time in higher altitudes expose your skin to stronger UV rays. The higher you go, the thinner the atmosphere becomes, so sunlight becomes more intense even in cold temperatures.
5. Daily Winter Habits Still Expose Your Skin
You’re not protected just because you’re indoors more. UVA rays pass through windows, meaning your skin can still be damaged while you're driving, working near a window, or relaxing at home. Daily SPF keeps this type of damage in check.
