I am really beginning to question and wonder about Dermatologists. Why is it that 99% of derms out there tell you that Retin A can't harm or damage the skin? Why do they insist that that it ONLY makes skin beautiful as long as you "keep at it!"? Before trying Retin A I read all the reviews. I also read a few horror stories and like everyone else, I assumed, well they must have just not applied...
