Airbrush tanning refers to the process of applying a DHA based sunless solution to your skin with an airbrush. The solution is applied evenly to your body by hand using an airbrush designed for sunless applications. The whole process should take less than 20 minutes and result in a perfect looking tan that will last 5-10 days.
Every day, millions of dead skin cells are sloughed off or worn away from the surface of your skin. In fact, every 35 to 45 days, you have an entirely new epidermis. This is why tans from sunless- or self-tanning lotions will gradually fade — as the dead cells are worn away, so is your tan.
