It’s fantastic.
Running a cycle used to give me some gnarly, DEEP cystic acne all over my back. I tried scrubbing the crap out of it with a loofa, tried dish soap, tried nizoral, tried salicyclic, tried benzoyl peroxide. Nothing put a dent in it, and it HURT.
After a lengthy period of BnC, I PCT’d and was natty for about a year. Acne went away.
I went back to BnC, but started running 20mg accutane from the start. I still get some tiny little surface pimples if I don’t change my sheets frequently enough, but it’s basically resolved.
Carry chapstick, wear sunscreen if you’re in the sun, avoid alcohol in general. Chapped lip / dry skin sides have been extremely minor for me.
