Beware! I used Diane 35 for almost two years and it was a disaster. It cleared up my acne after about six months to a year, but it made me depressed, unable to sleep, I gained weight, and after about a year I felt like a different person. It was very scary. Once I stopped taking them, it wasn't long before the acne came back. Honestly, do yourself a favor and try to do this as naturally as possible. Read "Women's Bodies, Women's Wisdom" by Christiane Northrup. Go to see a good Naturopath. Check out the book "Eat Right For Your Blood Type"(it's really working for me). Be kind to your body and when you wash your face be gentle and try to visualize your acne healing. Positive thinking is so important. The body is perfectly capable of healing itself, you just need to be patient and take good care of yourself.
