How do sun-screen lotions and creams protect us from the harmful effect of sun’s rays?
UV rays in the sunlight can cause skin disorders and burns. This damage caused to the skin can be pre-vented by applying sun-screen lotions and creams. These lotions have sun-screen agents like Ethyle Para Dimethyl-Amino Benzoate which forms a very thick protective layer on the skin surface, when applied. These agents filter out most of the harmful rays and allow only the beneficial ones to pass through.
