acne.org regimin and all that (wash face only twice, no soaps, etc)
The distinctions arent super rigid. Point is severe acne (cysts, nodules) can't be treated with otc remedies or drugs or "lifehacks" and pretty much 100% require accutane.
Less severe acne you could maybe try some random things to see whats what, but if you have acne thats causing SCARRING, dont fuck around with anything but accutane, because scarring is permanent and lasts for life, no matter what you do.
So if you have acne and its causing scarring, get on accutane.
Also don't go to
acne.org, the only people who use that are bitter angry teens whom accutane did not work for, so there is only sensationalistic shit about how bad accutane is.
I listened to those cucks and prolonged treatment with accutane by 1 year, and got about 10 new deep scars. Then i went on accutane, 15g total, 8 months, and the worst i had was dry lips.
You just have to try accutane and see if it works for you, dont listen to hysterical teens and ignorant people who will attribute a red mars to accutane.
