A self-tanner is a lotion, cream, mousse, or spray that is applied to the skin to give it a darker, tanned appearance. Self-tanners work by interacting with the amino acids in the skin to produce a pigment called melanin. Melanin is the same pigment that gives skin its natural color.
Self-tanners can be used to achieve a variety of looks, from a subtle glow to a deep tan. They are a popular alternative to sunbathing, as they do not pose the same risks of skin damage and skin cancer. Self-tanners are also a good option for people who have difficulty tanning naturally.
