Do not under any circumstances, wax sunburned skin, as it has a tendency to come right off! Think about it... red chapped raw hairless legs don't look much better than red fuzzy legs. Wait for a normal skin tone before waxing. Also, never wax yourself if you are taking accutane or using retin-A. Both of the above medications are keratolytics and increase the rate at which your skin exfoliates. If you take a chance and wax, you may remove skin as well as hair! Don't do it!
