I've been using retin A for a year and am currently using the .1% strength. For my birthday I got an exfoliating brush which I used twice a day for 2-3 weeks, and I probably shouldn't have done that because now my skin seems overexfoliated (redness, bigger pores etc.) I haven't used the brush for a month or so but my skin still looks a little rough. I'm currently using the retin A every night, should I scale it back to once every other night until my skin is back to where it was?
