About two weeks ago I shaved my bikini area and used Nair because we were going to the river. When I got into the river the water was so hot it scalded the area that I shaved and used wax. Plus, during the summer I tend to sweat in this area and under my breast and of course I get really irritated. I use poweder under my breast and that seems to keep me dry, but my bikini area still has not healed. How can I treat this area?
