For best results, exfoliate at least 24 hours before your session and focus on the driest areas - elbows, knees, hands, feet and the backs of your ankles.
Shave at-least 24-48 hrs before your session using a razor that lacks a moisture strip.
The day of your spray tan, don't use moisturizers unless they are specifically formulated for sunless tanning (oil free).
Forgo any lotions, oils, deodorant, perfumes, or makeup the day of your appointment. All of these can create a barrier on the skin that the tan will not adhere to.
Any bar soaps/cream-based body washes (Dove specifically) are known to leave a residue on the skin and can create a barrier that the tan cannot penetrate through and may leave streaks. Any gel-based body wash is best.
Showering should be completed at least four hours prior to tanning to allow your pH levels to neutralize.
If you must shower within four hours, run cold water at the end of your shower.
