To be entirely honest, I am not sure what this does in the long run, but I keep using it because of the texture and the way my skin feels. I use this as a second moisturizer/serum over recently cleansed skin before makeup. It's slightly cooling and so slippery and soothing in a way no other product is. After, my skin feels like silk and makeup goes on great. I haven't noticed anything magical with my skin, but I enjoy using it so much that I am in love.
