I like this product more than I expected. When I ordered it, I didn’t realize it was only 3% glycolic avid, which i figures was too small of a dose to make a difference. To my surprise, it tingles upon application, which is a good sign that the glycolic acid is affective at breaking through the first, tough layer of skin. I have a actually seen an improvement in texture in just four uses! I used another AHA product last month, so I’m not anticipating a huge purge phase since that’s only about one natural skin cycle, but we will see. The only drawback is the smell. It smells very dated, like mature women’s perfume. The smell actually reminds me of something my grandmother used before she passed away. Other than that I would highly recommend this product! Still curious to see how a lower dose of glycolic acid continues to work on my skin, but so far, so good! This is priced great too. The smell is also better than the heavy fragrance of the Pixi Glow Tonic.
