Spray tanning is a cosmetic process that involves applying a fine mist of tanning solution to the skin to achieve a bronzed appearance. This method is popular because it provides an even tan without the harmful effects of sun exposure or tanning beds. The solution typically contains a color additive called dihydroxyacetone (DHA), which reacts with the outer layer of the skin to create a temporary tan. The application can be done at home using spray cans or through professional services at salons. The results usually last about five to seven days, depending on skin type and care. To maintain the tan, users are often advised to moisturize and avoid exfoliating products.
