Just a thought- I have read that you can go see your dermatologist and get something to clear it up! I have the same thing with my underarms- and was told it is a form of dry skin and can be taken care of by products the have Retinol or Retin-A in it. Because Retinol is a powerful lotion that takes the top damaged layer of your skin off. ( not painful- i used it on my face before and the only thing is you have a new layer of skin now and it is really sensative to sun light and some parfume products.) I hope this helps!
