Repeated exposure to sunlight leads to dark spots on different parts of the body. This is because; production of melanin (a pigment responsible for skin color) is doubled when it gets exposed to sunlight. Along with other external and internal factors skin develops brown or dark spots.
To protect the skin from dangerous rays of sun light, use of sunscreen increased. This repeated use of sunscreens resulted allergic reaction in few sensitive people. Most common sign of sunscreen allergy is contact dermatitis.
Chemical ingredients are included in sunscreen creams to block harmful sun rays or to absorb the radiation. But few active chemicals like Para-Aminobenzoic Acid, Benzophenones, Cinnamates, Benzyl salicylate and Octocrylene in the cream can trigger allergic reaction.
