For a friend..

Back in the day I remember a few posts and a few people having mad results with something.

IIRC Tear posted it, in my head I have apple cider vinegar?
Some other stuff as well but his progress before and after pics were mad.

Apparently ACV with "The Mother"

Some guys were doing shots of it, others were applying topically. Pretty sure Tear was shooting ACV enemas, but that's never been confirmed.

Yo real talk, use urine. Wash your face with it in the shower each day and it'll clear up in a few weeks.

How bad is the acne? If it's severe use roaccutane; otherwise known as oral isotretinoin. If it's mild-moderate there are gels your doctor can prescribe, and use it in conjunction with a salycilic acid exfoliator at night

two of my favorite over the ponders in one thread

Clean up your diet, I used to look ugly as fuck face full of acne, and then after about 5 months of eating clean I saw results.
Fuck all the neutrogena wash bullshit, unless you clean up what you put in your system you won't see long term results.
Less processed foods is what you neeed.
