With all the glowing commendations for this product, I figured I couldn't go wrong by purchasing it. Wrong, wrong, wrong. I followed the directions; I didn't leave it on longer than 8 minutes, and I didn't use it more than once a week. I rinsed with cool water and used a noncomodogenic moisturizer afterwards. I didn't lay out in the sun. Now, 6 or 7 weeks later, my skin has never been in such terrible condition. Where I was only having mild breakouts before, my face now resembles that of my acne scarred adolescence. I cringe when I look in the mirror. Please, save yourself some trouble and DO NOT buy this product.
