With proper care our spray tan should last between 5-7 days. Like a suntan, a sunless tan fades gradually as your skin cells shed. To help maintain your tan, apply lotion twice daily. Want a long-lasting glow? Regularly scheduled follow-up tans will get you there. Any exfoliation will expedite the removal of the tan. So the less you are exposed to extreme heat, water, sweat, excessive rubbing, shaving, the longer your tan will last
