here's the thing, a lot of things that look like acne - arent. to the avg. person on the street they are, but technically they can differ. and some acne treatments wont actually help w/ whatever "acne" condition you have. i used benz. perox. and it didnt help. plus a supply only lasted 2 weeks and had to be refridgerated (that was a pain) and stirred on few occasions
i'd go to a dermatologist, grab some retin-a (they'll give it to u dont worry) and try that
if u go to a normal doc, they'll prolly start u w/ the b.p. - but a dermo will give u the r-a - which is prolly ur best bet.
i dont think that a high dosage of vitamin A will work - its not the same as Accutane - so i wouldnt try to substitute it for the real thing.
maybe u should go to a doc and find this out for sure tho
