acne
"I am about to start using retin A. I really do not have facial acne. The little pimples r nothing to mention.
My issue is body acne (ew). I have acne on all of my upper body. My arms, shoulders and especially my back. Especially my back. Plus I had chicken pox last summer so I have a lot of scarring. I have noticed that my face gets rid of scarring quite easily. My face is clear and ok... just a bit of discolouration. No biggie.
So I wanna know if I can get .025 %  to begin with rather than .01% or should I just work my way up. Also... when someone says "work your way up" do they mean to finish a tube with a certain strength then move to a higher concentration.
Also, can I stop using it and be fine or will it cause me to break out after I stop?"
