I had dark underarms for years and was really self-conscious about it. I wouldn't wear anything strapless, not even for a party. I tried everything: really expensive creams, lemon, and nothing worked. Some even burned terribly. I use this gently in the shower and my underarms have slowly evened out, without any irritation at all. The best part is that it rinses off in two seconds, and by the time I get out, it's almost dry hanging up. It was worth every penny; I already ordered another one as a backup!
