Summaries are ours, written from the abstract. Caveats kept.

Physiochemical properties and application of hyaluronic acid: a systematic review
A systematic review of hyaluronic acid across medicine, not just skincare. Tissue hydration, elasticity and durability improved. Worth knowing: much of the strongest evidence here is for injected fillers and joint injections rather than a serum you smooth on.

Hyaluronic acid, a promising skin rejuvenating biomedicine: A review of recent updates and pre-clinical and clinical investigations on cosmetic and nutricosmetic effects
Reviews hyaluronic acid in cosmetic use, reporting real anti-wrinkle, hydration and skin-tightening effects. Read the detail though: the strongest results come from injected fillers and dermal injections, not from a lotion.

Benefits of topical hyaluronic acid for skin quality and signs of skin aging: From literature review to clinical evidence
Your skin starts losing hyaluronic acid from around the age of 25. This reviews topical HA for skin quality and ageing, and reports a randomised trial pairing an HA serum with botulinum toxin injections.
