Do you know how spray tans work? There are two types of spray tans: Airbrush tans, where an aesthetician actually mists sunless tanner onto your skin; and spray-tanning booths, which automatically cover your body and face with sunless formula. The first is the best way to get an even, sun-kissed glow.
Airbrush services are typically offered at salons. Spray-tanning-booth sessions, such as those by Mystic Tan and California Tan, are more widely available. While they are less precise, they are still effective: They hit hard-to-reach spots like your back.
Whichever way you go, always arrive with clean, lotion-free skin. Wear something dark and loose. Do not shower for at least eight hours afterward – and when you do rinse off, use lukewarm, not hot, water. [source: Star]
