Wear Sunscreen in the Winter - Here's Why
In the winter, the days are short and the cold temperatures tell you the sun isn’t as strong. UVB rays are weaker in the winter, so you don’t get sunburned as easily, but the UVA rays that cause photo-aging are just as strong. Because you aren’t getting burned as quickly, and because the warmth feels good on your skin, you aren’t seeking shade as often. Depending on your activities, you could actually do more damage in the winter than the summer!
Before we get into why you should ALWAYS wear sunscreen, even in the winter, you must understand a little something about UV exposure.
There 3 types of UV rays, UVA, UVB & UVC
All types UV radiation exposure damage the genetic material, or DNA, in your skin cells, and even cause eye damage. If enough DNA damage builds up over time, it can cause cells to start growing out of control, which can lead to skin cancer.
UVA, which I like to call the “aging rays” are what causes sun damage, penetrate more deeply into the skin can cause skin cancer, eye damage, and play a greater role in premature skin aging, including wrinkle formation.
