Detailed explanation-1: -The outer layer of the skin has cells that contain the pigment melanin. Melanin protects skin from the sun’s ultraviolet rays. These can burn the skin and reduce its elasticity, leading to premature aging. People tan because sunlight causes the skin to produce more melanin and darken.
Detailed explanation-2: -Melanin is a UV-absorbing agent and is able to protect the skin against the effects of UV light on the skin’s surface. It also offers protection against UVB and blue light. Eumelanin protects the skin from UV light, whereas pheomelanin does not.
Detailed explanation-3: -limit your sun exposure. stay indoors from 10 a.m. to 2 p.m., when the sun’s rays are strongest. wear protective clothing, such as sunglasses, long sleeves, and hats. avoid tanning beds. 25-Nov-2019
