Wow! This article really surprised me. As far as fighting those fine lines and wrinkles, plus stimulating collagen, I always thought that Retinol was the way to go. The only issue is that it’s super expensive, and prescription only. Apparently, according to this dermatologist, Glycolic Acid is much more effective, and results are visible much quicker than Retinol. Also, you don’t need a prescription for Glycolic Acid, and it is pretty easy to find!
