From what I've read it appears that ACV is good for clearing up the spots left over from acne, not actually preventing or curing new acne. I also have relatively bad Acne and I apply diluted ACV to my face about 3 times a day; it does appear to minimize the spots, and if nothing else, it minimizes redness. So, if you have a lot of left over spots, then it should help noticably. I don't know if you have or not, but you should also look into colon/liver cleansing; I've been doing both for a while and I am seeing improvement (on my fourth flush). Well good luck, and just ask if you have ant more questions.
