Efficacy and Tolerance Evaluation of an Anti-age Food Supplement

Aim of the study was to evaluate the anti-age activity of "Pre-Hyaluron 465 Innēov" a food supplement, composed with a precursor of HA (glucosamine) and an enzymatic co-factor of HA synthesis (manganese), taken for 4 consecutive months by female subjects aged 35-60 years (with preference for subjects over 45 years), with moderate-severe skin aging/photoaging according to a reference photographic scale.
