These ripped off the skin from above my lip. I have been waxing for years and have never had an issue until I used this product last night. I'm now at work with a bright red "moustache" of raw skin and a coating of antibiotic ointment. Unreal.
I thought it was caused by retin-a but I waxed with a different product a few weeks ago with no adverse effects. Then I google'd this product and saw this has happened to many other people and some claim they're chemical burns.
Buyer beware unless you're looking to get rid of some smokers lines!
