What are uva and uvb coverage?

Sunscreen : Uvb rays are responsible for suntan and sunburn they are the main culprit for skin cancer. Uva rays penetrate your skin more deeply. Prolonged exposure cracks and shrinks the collagen and elastin in your skin, which is why uva rays are responsible for signs of aging including wrinkles, saggy and leathery skin, and sun spots. A good sun screen should help block both.
