Wait at least 8 to 12 hours before washing, after your airbrush tan session. And for the most beautiful, longest lasting tan develop a healthy skin regimen. Apply moisturizer the morning and evening after your post-tan shower. Avoid moisturizers with AHA (Alpha Hydroxy Acid, since they promote exfoliation), long, hot showers and baths, and scrubbing the skin. Keep in mind that chlorine in swimming pools and hot tubs can remove or shorten the longevity of your airbrush tan, and excessive friction on the skin may fade your tan prematurely. Avoid the use of a washcloth or exfoliator when bathing. Pat your skin dry after bathing or showering. Take care when exercising as friction and excess sweat may cause your tan to fade prematurely or unevenly.
Your tan will naturally start to fade as your skin normally exfoliates. Once your tan has completely faded, it is ok to start the preparation and treatment all over again.
