I was on Retin-A Micro for a while, at first it worked great, then after a while it didn't do much for me.
I started Tazorac in July. I use the gel, and I only use it every other night. It really makes my skin peel, in the shower I rub light circles on my face with my finger tips and the dead skin washes right away. I was told that my skin would get worse for a bit (I go to my derm every two weeks for a few extractions) but for the most part I am noticing a positive difference from the month I have been on it.
My skin is a corabination of oily/dry, depending on the week. I do not consider my acne severe at all, but my skin is never 100% clear..I mostly break out on my forehead and cheek area.
Good luck with whatever you choose!
