A very good product with high content of glycolic acid (chemical peel) that possibly not everyone can tolerate (you also, by the Abpeelen the upper layers of skin, be sure to wear sunscreen during the day!) It really works for wrinkles and helps to better durchfeuchteter skin (other products with similar concentrated glycolic acid cost a lot more). Will still secure me some remainders, since it is no longer sold by Olay in Germany / Austria. Pity!
