UVA rays are the ones that are most harmful and can cause tanning, early ageing of skin, wrinkles & fine lines

UVB rays on the other hand are the ones that are responsible for sun burns & in extreme cases, skin cancer.

Now the important thing to bear in mind is that no sunscreen is going to give you 100% protection. But that does not mean you should skip this step in your skin care routine. Using a broad spectrum sunscreen is the only solution.
