I read the feedback on this site and agree with the person who said carrot juice worked for cystic acne. I have suffered from acne since my teens and have a 100% guarantee that works! I found a book called Best Face Forward at a thrift store and did some of the things suggested:
1. I started working out daily to get my circulation going and get my pores revved up.
Remember, your circulation flows upward.
2. I kept my hair washed often to keep the scalp free of excess oils.
3. I ate carrots (raw) and sweet potatoes like they were going out of style! You have to eat plenty of them every day. The vitamin A and E are good for skin, nails, and hair. I also cut out anything fried, like chicken, pizza and french fries, etc. and put no mayonnaise or dressing on my salad.
4. I washed my face with Aveeno oatmeal soap and with Palmer's cocoa butter soap, in that order. The oatmeal dries up the pimples and the cocoa butter fades the scars and dark marks. Any oatmeal soap will work though.
5.I drank plenty of water!
I did this in high school starting in june and by the time school started back in august, my face was clear! I mean not a mark anywhere. My classmates remarked how clear my face was and asked what I had done.Even my mom was surprised and a Mary Kay representative that she worked for who had previously tried to get me to try her products asked what I had done.
I hope this helps somebody. I had tried Retin A and tetracycline, but decided to go with the suggestions in that book. Tetracycline can be hard on the stomach and Retin A smells bad and you need to limit your sun exposure.
