Review title is Excellent product [SEP] This stuff is the best! I've been using it for years then couldn't find it on the shelves anymore. Thank goodness for Amazon. The 12 % glycolic acid this product contains is perfect for exfoliating your skin and not burning it. It makes the skin smooth and younger looking. Just make sure to use a good moisturizer after it dries otherwise you'll have very dry looking skin. It really works well to smooth out tiny lines and blemishes too.
