How Body Bronzing Works« back to Spray TanningThe "magic" behind Sun FX Spray Tan Body Bronzing The answer is a chemical called dihydroxyacetone, or DHA. DHA begins working when oxygen hits it, creating a reaction within the top layer of your skin (the dead cells) that results in visible darkening. This chemical reaction with your skin also helps explain that "self-tanner smell." Just like when you get out of tanning booth, there's a definite scent associated with DHA being activated. Even those self-tanners that claim to have a fresh or fruity scent really only smell that way when you first put them on. Either way, they are the healthiest way to tan, and the only way to get a beautiful, bronzed glow without damaging your precious skin. Trust us-self-tanners fade, but leathery, sun-damaged skin doesn't!
