They say: A facial serum with 100% natural Hyaluronic Acid extracted from "a vegetable similar to a wild yam." This serum promises to provide a punch of moisture while stimulating collagen production for long-term benefits.

We say: This products works. Period. Our tester reported plumper, more youthful-looking skin with just one use (although, of course, its was temporary). Skin appeared more moisturized - and stayed that way all day long. With proloned and consistent use, this HA serum might just be a game changer.
