I have been using these hair removal pads on my legs for many years (over 20 I think). As a former college swimmer I shaved with a razor all the time - my whole leg. But i WAS a klutz with a blade and always cut my ankles and sometimes my knees. Plus it had to be done more and more often. When I discovered this I had doubts but each time I noticed that the hair was less and less course and took longer and longer to appear. AND of course I never cut my self either. I wouldn't change to any other method. My daughter has never used a razor either and her hair is darker than mine!
