A few years ago, I received a sample of this product with my Sephora order and have been hooked ever since. I've used countless masks/exfoliants in the past and nothing compares to Philosophy's Microdelivery Peel. It's simple to use, takes only a few minutes, and leaves my skin feeling soft, smooth, and instantly refreshed, as if I just had a professional facial. I use it weekly and have seen a noticeable difference in my skin. Stock up now through April 21st at Sephora and get 15% off by entering coupon code chic.
