I hadn't used this product for over a year because it contains retinol and I was pregnant and breastfeeding, and OH MY GOD did I miss it! I just repurchased it a week ago and from the first use my skin felt so soft and smooth and looked better the next morning. I use it about twice a week before bed. It helps any other product that I layer on top of it sink in more thoroughly and therefore, in my opinion, helps other products perform more effectively.
I first discovered this product about 6 years ago, when my skin was horribly irritated and broken out. I was using harsh products designed for acne prone skin. I happened to visit Sephora on a day when a Dr. Dennis Gross rep was there and she explained that I was overdrying my skin and contributing to the irritation. I bought the peel pads and the retinol & ferulic moisturizer. The combination of those two items saved my skin, and within a month my skin looked so much healthier. I'm a loyal fan of the brand.
