When I read about the benefits and ingredient list of this serum I was literally amazed. This serum is so lightweight and has a light fresh scent. It absorbs quickly into the skin and leaves the skin feeling soft and smooth. I have been using this every night for the last 10 days so I have not been using this long enough to see all of the benefits but my skin is definitely softer and I am seeing a difference in my skins texture. I did get a slight cooling sensation the first 2 days I used it but that is normal. I feel so good that my skin is protected from the effects that electronics can have on the skin. I also like that you get the benefits of retinol with out the negative effects that retinol sometimes has on the skin like sensitivity to the sun, irritation, flakiness, etc.
