Answer :
Exposing to ultraviolet (UV) light stimulates the production of melanin, which darkens the skin.
Ultraviolet (UV) light exposure triggers a physiological reaction that includes the production of melanin. Melanin is a natural pigment that gives skin its color. It acts as a defense mechanism against harmful UV radiation by absorbing and dispersing it, preventing DNA damage from occurring. Melanocytes in the skin are stimulated by UV radiation to produce melanin, which gives the skin a tan appearance.
Exposure to ultraviolet light stimulates the production of melanin, which darkens the skin. As a result, melanocytes become more active and produce more melanin, resulting in a darker skin tone. Melanin absorbs the UV radiation, protecting the skin from damage. The more melanin in the skin, the less likely the skin is to burn and become damaged.
