This product was given to me as a Christmas gift. My breast are rather large and I do experience a great deal of sweat and perspiration under my breast. This product is fantastic. Because of all the sweating, I was scratching a lot which was discoloring my skin under my breast. But after using this product for even a few days, my natural color came back, the sweating and wetness went away. What a relief!! I am a gym instructor so I do a lot of sweating and this product has just made my working out a pure joy. I have already started recommending this product to other ladies and will continue to do so. So whatever you do don't change your formula bec it works. When I run out I will be buying more. Thank you so much!! a
