Ingredient glossary / Humectant
Hydrolyzed hyaluronic acid
On the label: Hydrolyzed Hyaluronic Acid · Humectant
What it is
Hyaluronic acid broken into smaller pieces so it can sit a little deeper in the outer skin layer than the full-size molecule.
Humectants: Humectants draw water into the outer layer of skin from the air and the layers below; glycerin is the classic one.
In the research
1 PubMed papers mention it with skin, cosmetics or hair; the three most recent:
- Fabrication of High-Resolution Fine Microneedles Derived from Hydrolyzed Hyaluronic Acid Gels in Vacuum Environment Imprinting Using Water Permeable Mold · Gels (Basel, Switzerland), 2022
A paper is a paper, not a verdict: titles are listed so you can read them, and a study on cells or mice says little about a cream on a face.
