Description

The human body has its own mechanism of protecting itself from external factors that harm it. When the UVA and UVB rays from the sun attack, the skin produces Melanin in the epidermal layer of the skin. Melanin acts as a protective shield against the sun’s harmful effects. The skin, as a result, darkens in color. This is called sun tan. Sun tanning over period of time leads to a dull, lack-luster skin with blemishes and black spots on the tanned areas. A sun block helps in keeping a tab on the tanning process, saving the skin from damage.
