I've been using this serum for more than a month and I love it. When I started using it I had a scratch on the skin between my nose and upper lip, and in a few days the scratch was completly scarred and barly noticable, so the serum did a wonderful job by healing my skin. I've been really enjoying this serum, I use it day and night and it feels so refreshing and calming on the skin, I've used  half of the product so far and I'm going to buy it again. It's so freaking good!
