Airbrush tanning is a form of sunless spray tanning. The solution that is sprayed on the skin includes a cosmetic bronzer that gives the client a “just off the beach” look instantly. The ingredients in the sunless cosmetic bronzer are similar to those used in cosmetic foundations or powder bronzers. The DHA, or dihydroxyacetone, is the active ingredient that interacts with the top layer of your skin cells to produce the tan. After 24 hours your results are a natural-looking tan that lasts up to 7 days.
