My girlfriend has had acne since she was in puberty (she is now in her early 20s) and has tried most everything to treat it -- prescription benzoyl peroxide creams, salicylic acid washes, retin-a cream, antibiotics, sulfer drugs, etc. She is healthy -- exercises, sleeps well, eats well, etc.
I know that everyone is different and has unique skin -- but is there something that has really been proven to work effectively for the treatment of acne? I have heard Proactiv is a good product, but I hate to introduce her to yet another overpriced, ineffective product. Any help you can provide would be much appreciated!
