What causes a tan to fade?
Tanning takes place in the top layer of skin, the epidermis. This outer layer, with oxidized melanocytes, is shed every 30 days, causing the tan to fade. Indoor heating, hot water and harsh soaps can hasten the fading process. Well-moisturized skin, increased water intake, neutral ph soap and showering in warm water can increase the longevity of your tan. Regular tanning sessions are also needed to maintain a great tan.
