Yes I tried this to remove some of my old acne scars. It does work to some extent- my skin looks and feels soft and the scars are actually becomiing smaller with constant use! it makes me feel good and i relly on it for a good facial 'lift'. it is actually very cheap compared to other conventional peels. Although it takes plenty of time - many months to see appreciable results. they should have it in a couple other stronger concentrations. But over all i am happy with this product. It surely deserves a 4.5 out of 5.
