I bought this for myself because I started to see some wrinkles on the corners of eyes and mouth. I used this twice a day and after 3 weeks, I could see a noticeable change in my skin. The wrinkles around my eyes started to fade away and the finer lines were completely gone! The ugly grey pouch under my eyes were not noticeable anymore. The serum made my skin so smooth and silky. After each use, I could tell my skin was absorbing the serum and being replenished. I have used other serums from Olay and Mary Kay, and this is the best one by far.
