A closer look

What the research shows

Human oral and topical research

Melatonin, vitaminE and beta-glucan formulations complexed with chitin nanocrystals improved some reported skin measurements over noncomplexed formulations.

What this does not tell us

70 subjects, 12 weeks, combined oral/topical delivery and three co-actives. Nanochitin delivery effects cannot establish standalone bulk-chitin anti-aging benefit. Chitin-glucan copolymer studies are not substituted for chitin.
