It is recommended that you shower and exfoliate before your tanning treatment. Also, make sure your skin is free of any lotion, oil, gels, or any other type of product that would prevent your skin from receiving direct spray application. Also, you must wear loose, dark clothing and sandals for at least two hours after application. In order for the application to be most effective and to allow it time to react with the skin's proteins, you should wait at least eight hours before bathing, sweating, or rubbing yourself where you had the application applied.
