I first bought this serum at my dermatology office. I was very thrilled when I found it on this website. This serum has smoothed my skin and when put under my foundation giving me a very moisturizing feel. I have since bought it twice and will make this a daily ritual. I have been told my skin does not look like a 50 year old plus.
