I used a product called certain dry about a year ago. And since then I've had problems with my underarms. The first day I used the product it seemed to work but then it irritated me so bad that it made them red and are now black. I figured that with time they would heal but no luck. Now that I try to wear deodorant it stings so I've been using a product called gold bond baby powder but it still hasn't worked. I've used so many things already. Please help me I'm desperate of not finding anything that works

Have you been to a doctor?

Try to rub your underarms with pumice!! It scrubs off your dead skin cells!! :D
