just follow what they say on
www.acne.org and its very similar to what a general dermatologist will give you. basically a topical cream and the recommendation that you use a gentle cleanser, etc. just take the time to educate yourself on it -- its not a big deal. the benzoyl peroxide through that site is much cheaper than what you'll be given by your derm.
unless, you have some hardcore acne -- then maybe you need accutane or something. but for moderate or mild I think gentle cleanser + benzoyl peroxide + moisturizer twice a day will do the trick.
