Which pigment absorbs UV rays to protect the skin?

Melanin is the pigment that absorbs ultraviolet rays and helps protect the skin by dissipating UV energy, which reduces DNA damage in skin cells. It’s produced by melanocytes in the epidermis, and its amount and distribution influence how well the skin shields itself from sun exposure. When exposed to UV light, melanin production can increase, leading to darker skin or a tan as a protective response. The acid mantle is a protective film of sebum and sweat that supports barrier function but isn’t a pigment. Langerhans cells are immune cells in the epidermis that detect and present pathogens, not pigments. Adipocytes are fat cells that store energy and provide cushioning, not UV protection.
