Glycoproteins

Glycoproteins are proteins with sugar chains attached to them. They're naturally found throughout your body, including your skin's extracellular matrix.

In your skin, glycoproteins work alongside collagen and other structural proteins to keep everything held together and functioning properly. Their sugar components make them great at binding water and keeping the skin hydrated. They also part of the extracellular matrix that plays a direct role in wound healing.

The glycoproteins found in skincare are most commonly derived from yeast, algae, or plant sources.

In-vitro studies have shown that yeast-derived glycoproteins can boost cellular oxygen content and increase energy production in skin cells.
