Topical Hyaluronic Acid
A good humectant that plumps the stratum corneum for hours — cosmetic hydration, not anti-aging.
B
Evidence grade B
At least one good RCT or consistent controlled studies
Mechanism
High-molecular-weight HA binds water at the skin surface; it does not penetrate to the dermis where injectable HA acts.

The full read
Expect a smoother, temporarily plumper skin surface, especially in dry climates (apply on damp skin, seal with moisturizer). Marketing conflates it with dermal fillers — same molecule, completely different depth and duration. Useful supporting act; not a headliner.
