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 dihydroxyacetone (DHA), a colorless sugar that reacts with the outer layer of the skin to create a temporary tan. The application can be done at home using self-tanning sprays or professionally at a salon with a spray tanning booth or by a technician. Results usually last about five to seven days, depending on skin type and care. Regular exfoliation and moisturizing can help maintain the tan longer.
