One time I used glycolic acid cream and it did not work. I even did not finish it because it dried my skin too much.

Are you talking about glycolic acid peels? I had one done by a dermatologist that helped and another one done by a beautician that didn't. I think they do help alot if you go to a reputable dermatologist. The higher the strength, the higher the recovery time and the better the results.
