Tretinoin
"I've used this product before and it did wonders for my skin.. My skin did start to get red and irritated so I just used it every other night or skipped a few days in between. I had a lot of scaring on my cheeks large pores and oily skin and it completely cleared my skin. I remember my cousins girlfriend asked me if I had makeup on.( My skin was flawless) The first time I tried this product it was 0.1 percent cream and now I just started using 0.05 percent gel I hope it has the same effect keeping my fingers crossed"
