Glycosaminoglycans are water-binding molecules naturally found in the skin that help maintain hydration and elasticity.

Hyaluronic acid is the most well-known example. In skincare, GAGs support skin structure, improve firmness, and help deliver long-lasting hydration.
They are often included in anti-ageing and reparative formulas to restore plumpness and smoothness.
