Fortunately, there are safe alternatives. Most dermatologists consider spray and airbrush tanning as safe as applying makeup.
The active ingredient for sunless tanning, dihydroxyacetone (DHA), is derived from raw sugarcane and sugar beets, which reacts with the skin’s amino acids to produce color. This color develops three to four hours after application, deepens over the next 24 hours, and lasts one week to 10 days. A session usually takes 30 minutes or less and may be performed in a spray booth or with a handheld spray unit. Clients undress to their level of comfort; many wear bathing suits. The solution easily washes out of fabrics you wear to your session and, in general, does not rub off onto clothes.
You’ll still need to wear sunscreen, as spray and airbrush tanning don’t provide protection from the sun.
