Once the airbrush tan sets, the color will not wash off with ordinary soap and water. However, the tan will gradually fade over time. To prolong the life of your tan:Moisturize: Apply a non-oily moisturizing product twice a day, and drink plenty of water.SPF: Avoid using a heavy oil-based SPF, and consider a light-weight cream or dry-oil based SPF when outdoors.Working Out: Wear loose-fitting clothes when exercising, and apply baby powder to your "hot zones" to prevent friction.Limit Skin Exfoliation: Gently cleanse the body with a body gel wash instead of bar soap.Shaving: Use a fresh blade when shaving and press lightly on the skin.
