if you really want to get rid of the acne, you should try a product called skin free.
its a product developed for the south african climate... i've never actually used it but...

i know one of the Miss SA's, Kerishnee Naiker, had terrible acne and she used skin free and she had only great things to say about it.
i just let mine ride out...my dad always use dto tell me just plain soap and warm water...thats what he used to clear his up when he had acne too.
i hope you find something.
