mks2005 said:www.clearskinregimen.com (also, see www.acne.org for some history about it) is pretty much the only decent way you can tackle it without resorting to antibiotics. (it's a benzoyl peroxide regimen that actually works).
your acne doesn't sound too bad and it doesn't sound like you need any antibiotics. you should be able to at the very least significantly reduce (probably completely clear up) with the topical regimen outlined on that website. be warned, it requires a bit of peserverance, but I think you'll realise it's worth it.
That clearskinregimen wesbite does work, did for at least

I have to say it didn't work either and it really made me smell of eggs. One of the products has sulphur in it.
