It's a "bioengineered" from of skin building block N-acetylglucosamine-6-phosphate (NAG6P) that is used by the skin to synthesize important skin-identical humectants like GAGs and hyaluronan.
According to the manufacturer's in-vitro and ex-vivo (made in the lab not on real people) tests, NovHyal can boost GAGs production both in the upper and middle layer of the skin by 84% in 10 days. It can also increase hyaluronic acid synthesis by 282% in just 2 days. Sounds good, though some in-vivo tests (made on real people) would be nice.
