Hi there -
I have been using Retin A micro for almost a year. Last year my oily yet normally pretty clear skin went through this crazy 3-month breakout. Usually OTC spot treatments kept things in check, but this time my chest, back and face were covered in acne! It was awful, first I was diagnosed with folliculitus and then was told what was on my face was acne. I tried many meds, both topical and antibiotics. My chest and back eventually cleared up with antibiotics and I continue to use Retin A on my face. At first, it made my face quite red, tender, and flaky. Like all acne meds, it does take a good number of weeks to see the results but it does work so be patient. Now I use it every other night or less and it keeps my skin clear and smooth with very little dryness, and I have no fine lines anymore. It is important to only use the
tiny amount like the leaflet specifies!!! That's all you need. Any more and you will be red and flaking for a week

AND, always use a sunscreen.
Take care!
