It's all pretty tempting when your face has exploded into little pus volcanoes; it's just too bad that it probably won't help.
The problem is that most of the acne process takes place underneath your skin, where soap can't even get to. In fact, aggressively washing your face with the strongest cleansers is more like likely to aggravate the situation by drying your skin out and roughhousing the part of your body that needs the least touching right now. Most soaps contain a chemical called sodium lauryl sulphate (or it's slightly less evil twin, sodium laureth sulphate). It's an agent that is super good at being foamy and super cheap to put into cleaning products. It also strips away the grease from your skin, which sounds great, but some of that grease isn't so much "grease" as it is "necessary skin moisture." So foamy acne soaps containing SLS end up irritating skin and provoking pizza-face flare-ups.
"Yes, yes, just try and wash me away! With every scrub, I only become more powerful!"
So What Should You Do Instead?
If you have a serious acne problem, go and see a real doctor, because you might need antibiotics to treat that shit and prevent scarring. But either way, instead of scouring your face with harsh cleansers, just wash your face twice or three times a day (but no more) with a gentle soap, or just warm water. Oh, and switch to something SLS-free. Only good luck with that, because it's in fucking everything.
