Spray tanning is a cosmetic procedure that involves applying a fine mist of tanning solution to the skin. This solution typically contains a color additive called dihydroxyacetone (DHA), which reacts with the outer layer of the skin to create a temporary tan. The process is quick and can be done in a salon or at home using a spray tan kit. The results of spray tanning usually last about five to seven days, depending on skin type and care. It is a popular alternative to sunbathing or using tanning beds, as it reduces the risk of skin damage and skin cancer associated with UV exposure.
