"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 &quot;work your way up&quot; 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?"
