        Ultraviolet radiation emitted by the sun affects, to some extent, the skin of everyone, but the reaction of the skin varies greatly from person to person. The extent to which a person is sensitive to sunlight depends on the pigmentation of his skin and his ability to tan.

        Four main factors predispose to skin cancer:

• Pigmentation of the skin and its ability to tan;
• Heredity;
• Exposure to chemicals;
• The duration of sun exposure.

        The tanning induced by ultraviolet radiation occurs in two ways: immediately or delayed. Instant tan is caused by the action of UVA on the skin. The skin takes on a colored hue during the exhibition, but it gradually found its natural color within hours or days. The skin is tanned or less, depending on whether his complexion is naturally dark and light tan depending on the legacy of past exposures.
