Multi-Weight Hyaluronic Acid

What is it?

Multi-Weight Hyaluronic Acid is a formulation approach combining hyaluronic acid molecules of different molecular weights, intended to deliver hydration benefits at multiple skin depths simultaneously.

What does it do?

Commonly used to provide layered hydration, since low and high molecular weight HA behave differently in skin: a controlled RCT found low molecular weight HA outperformed high molecular weight HA on skin capacitance, while combination high+low MW HA formulations (e.g. stabilised hybrid complexes) are used clinically in facial rejuvenation protocols.
