SUMMARY
Melanin, produced by melanocytes in the epidermis, is responsible for skin pigmentation and increases in response to ultraviolet (UV) light exposure from the sun or tanning lamps. This process results in a suntan, which serves as a protective mechanism against UV radiation. The darker the skin, the more effectively it can emit infrared radiation, while melanin absorbs UV radiation, reducing the risk of skin damage. Thus, the primary function of a tan is to provide a defense against harmful UV exposure.
PREREQUISITES
