Hydrolyzed Hyaluronic Acid

Written by Reviewed by the SYNC editorial team Published Last reviewed Editorial standards

Hydrolyzed Hyaluronic Acid — hyaluronic acid that has been broken down into smaller fragments through hydrolysis, reducing its molecular weight. These lower-weight pieces are designed to spread and penetrate more easily while still acting as water-binding humectants.

Key points

  • Hydrolyzed hyaluronic acid is created by breaking standard hyaluronic acid into smaller, lower-molecular-weight fragments.
  • Its reduced size is intended to help it reach deeper layers of the upper skin than larger molecules.
  • It functions as a humectant, drawing and holding water to support hydration.
  • It is often combined with higher-weight forms to hydrate the skin at multiple levels.

Frequently asked

Why use hydrolyzed hyaluronic acid instead of regular hyaluronic acid?

Its smaller fragments can distribute and absorb more easily, so it is often used to complement larger forms that mainly hydrate the surface.

Is hydrolyzed hyaluronic acid gentle on skin?

It is generally a gentle, well-tolerated humectant, though as with any ingredient a patch test is wise for sensitive skin.
