My best guess is that its the cause of friction but i'm not a doctor. I am not too overweight. I am 5'2 and about 160 lbs and 25 years old. Unfortunately I come from a Caribbean culture that highly criticizes skin perfections . This has cause me to come under scrutiny about my inner thighs and darker color under my butt. Its looked at as being dirty and that I dont take care of myself. I'm under a lot of mental stress and just want a cost effective way to clear this up
