*Do not brush your teeth, spray cologne, or put on tight clothes during your tanning time, which is 6-8 hours after your session. *You can apply a mineral powder on your face/body and wear lipstick and mascara if you are going out during your tan time. (6-8 hours after your spray tan).
It will take up to eight hours for your spray tan to fully develop, so try not to shower or bathe in this time. Taking lots of showers or spending time soaking in the bath can all fade your tan, so keep your washing sessions as brief as possible if you want to maintain your tan for longer.
