The sun radiates two types of UV rays that are destructive for your skin: UVA and UVB rays.
- UVB rays are damaging when the sun is shining and will make your skin red and burned. UVB are responsible for the DNA damage that leads to skin cancer.
- UVA rays are the longer rays, which means that they penetrate deeper into your skin and create the most damage (wrinkles, skin cancer, etc.). UVA rays are so strong that they are present all year round (even on a gray, rainy day) and can even penetrate glass, including car windows.
