Glycosaminoglycans

What Glycosaminoglycans is & what it does

Glycosaminoglycans are a family of long-chain sugar molecules that naturally occur in skin and connective tissue, with hyaluronic acid being the best known example. In cosmetics they function as humectants and skin-conditioning agents, binding water and helping the skin surface feel hydrated and supple. They are often added to moisturizers and sunscreens to support a smooth, plump appearance.

What do Glycosaminoglycans do in skincare?

Glycosaminoglycans are water-binding sugar molecules that act as humectants and skin-conditioning agents. They help the skin hold moisture and feel hydrated and supple. Hyaluronic acid is the most familiar member of this group used in cosmetics.

Are Glycosaminoglycans natural or synthetic?

Glycosaminoglycans occur naturally in skin and connective tissue, and cosmetic versions can be produced through biotechnology such as fermentation. Depending on the source they may be animal-derived or made by microbial processes. The ingredient class itself is based on naturally occurring molecules.

Are Glycosaminoglycans vegan?

Glycosaminoglycans can be vegan when produced through fermentation or other plant or microbial processes, but historically some were sourced from animals. Because the origin can vary, a vegan claim depends on how the specific ingredient is made. Check the brand's sourcing information if vegan status matters to you.
