photoaging of the skin
"I have been using Retin-A (Tretinoin) 0.1% cream for a little over a year. I had used milder products prior to using this to even my skin tone as well as diminish some enlarged pores but wasn't getting the result I wanted. Within weeks of using the Tretinoin my skin tone evened out and pores began to shrink. The first week I did experience some breakouts which for me had never happened before but I was informed this could happen by my doctor because the skin is expelling all impurities. The breakouts cleared and beautiful skin appeared. 
I've read horror stories but in each it's been clear that either their doctors failed to properly council them on this medicine OR they purchased online with little to no knowledge of how to properly use it"
