You need to use sunscreen in the winter for the simple reason the sun shines all year long. The most vulnerable places on your body during the winter are the face and hands. Many patients come see us to treat the dark spots that have appeared on the left side of the face from exposure to UVA rays while driving. In the winter, the sun’s heat is less due to the angle of sunlight, but the ultraviolet A and B rays are still strong enough to cause skin damage. When your skin is exposed to these rays it doesn’t matter what time of year it is. The ultraviolet rays can cause permanent skin damage.
- Snow and ice reflect UV rays. Sure, it might seem gray outside, but snow and ice reflect the sun’s rays. This means you should keep your SPF routine up on a daily basis.
- There’s a thinner ozone layer. Even though it feels colder outside, there’s actually more of the sun’s harmful rays hitting the earth’s surface and, yes, your skin
- UVA rays penetrate glass and clouds. The power of UVA rays are the same on a dull winter day as they are on a summer one. They damage your skin, leading to aging and skin cancer. Because these rays can penetrate to he deeper layers of the skin, they have more damaging effects on the skin structure causing loss of collagen and elasticity, resulting in sagging and wrinkling.
