What is the difference between UVA and UVB?
Did you know SPF 30 blocks 97% of the sun’s UVB rays?
Broad spectrum sunscreens are the best because they block both UVB and UVA rays. UVB rays penetrate into the epidermis and are more responsible for sun burns. UVB rays also play a key role in the development of skin cancer. UVA rays penetrate deeper into the dermis and can cause premature skin aging and wrinkles. So when choosing a sunscreen, make sure you look for broad spectrum coverage.
