I currently have been using a product that contains 8% Glycolic Acid and I really love this stuff! It works very well. However, I know that you can purchase stronger products online. In fact, I know that you can purchase the product that they use in the salon when you go for the 'acid peel' treatments. So I would like to hear from anyone who may have tried this application at home and how it worked and what you used. By the way, I'm not referring to shady back door products...I'm referring to legit products that are being sold all over the place. It's just I will pay 5 times more to get the treatment done in the salon vs paying online.
