Alcohol affects your blood sugar level to such an extent, that it may cause loss of bowel function control, and cause diarrhea, with the same side effects as vomiting. Cause-and-effect: Just like your knees go weak on you from too much booze, so does your bowel.
*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).
Once you've been spray tanned you can't shower for at least 8 hours. The first shower after receiving a spray tan should be a rinse. Keep water lukewarm and do not use any shampoo or body wash in order to keep pigment sealed in. Shower water will appear brown, but it's no cause for alarm. It's just the cosmetic bronzer washing off. Once the water runs clear, pat dry and apply a moisturizer immediately. A spray tan can last up to 10 days. The more diligently you apply moisturizer, the longer the tan will last and the more evenly it will fade.
