We now know the skin's own photoprotection mechanisms are usually not sufficient to protect against ultraviolet radiation for the sun. This UV radiation can result in damage like sunburn, changes in DNA, cell death or cell abnormalities.
Sunscreen therefore is of critical importance. There are 2 basic types of sunscreen: chemical and physical lotions.
Chemical screens are capable of absorbing UV rays and quenching the radiation so it cannot damage the skin.
Physical sunscreens, on the other hand, reflect reflect the UV rays, similar to a mirror.
Whether you choose a chemical or physical sunscreen, make sure the preparation protects against both UV-A and UV-B rays, to ensure you get the maximum sun protection.
