Wear dark, loose clothing after your treatment, any tight clothing or underwear may cause marks. Wear flip-flops or loose fitting shoes. Do not shower or bathe for at least 8 hours for the Norvell Professional Premium and either 1-3 hours for the Venetian One (depending on how dark you want to be. Do not go more than 3 hours). The wait time allows the colour to develop within your skin. In this waiting period you are going to look extremely dark. As for the Venetian One you may even look a tad grey, but rest assured after you shower you will have a beautiful sun kissed glow.
After showering / bathing, pat dry only. Then moisturize! This will help maintain your tan for longer. Long exposure to water and sweating from exercise will fade your spray tan sooner. Please remember that your tan does not have any SPF factor and you should wear sun protection as usual if you go outside. After 5 days, start to lightly exfoliate to ensure an even fade.
