On the day of your tan:
Scrub like there's no tomorrow
DO NOT moisturise.... including your face! (You don't want a white face and brown body!)
Avoid shaving
At your tan:
Remove all make-up
Remove traces of deodorant (green armpits aren't a good look)
Bring baggy clothes and flip flops to wear home (leggings ARE NOT baggy clothes!)
Post Tan:
Avoid too much shaving
Moisturise to your hearts content
Scrub every couple of days to allow even fading
