I've never tried it personally, but I heard a good natural treatment for acne was sulfur soap? I think it was called grandpa's sulfur soap or something like that, you can google it. I remember it being around 3 dollars.
There's also glycerine soap, which is made from vegetables, I use it and get it at the dollar store. I use that and a combination of apricot scrub, but I don't know if that'd be strong enough to help as I don't get bad breakouts, and I'm also pre-T.
