I have been using this serum for about six months and I can see such a big change in my skin. It looks more toned and tightened around the jawline and my "laugh lines" around my mouth have softened so much that they are barely noticable. This is an amazing product that I will continue to use. I use this sparingly and pat it on. While it is still wet I smooth out (contour) going from the center of my jawline up behind my ears. It's amazing how you can contour your own face over time. This product is a winner!!!
