HC3 is a highly potent facial serum that I recently tried. As you know, I don't make it a habit of raving for products I find mundane or ineffective. I had an opportunity to try this HC3 serum and it passed my check points. First it has a patented vitamin C ester, it's USA made and approved GMP facility. It is totally hydrating and does not contain any ingredients that leave any feeling of greasiness. As with most serums it should be placed under a good moisturizer. This is not organic, nor does this product tout any naturalness in terms of it's ingredients. What I do like is how it feels. For those women who can't seem to justify buying organic, those who don't really care about every since product being all natural and are more concerned about results- this delivers hydrated skin use as directed. This product can be found online. If you want a direct link to the one pictured from the distributor that I got mine from- just comment below and I will send or post you the place this one is from.
7/29/14 Additional update: This product appears to sit on the surface of the skin. I know this because I applied it in the evening and washed this off the next morning- I could feel the product washing away. This does not imply that this clear gel is sticky,thick or invalid for anyother reason. I just want you to know that it may create a non sticky barrier that helps the skin retain moisture. I am going to try this OVER another serum or moisturizer to see it's effect. :)
