Glycosaminoglycans
What is Glycosaminoglycans?
Glycosaminoglycans (GAGs) are a class of long, unbranched polysaccharides made of repeating disaccharide units, naturally abundant in the skin's extracellular matrix. They include types like hyaluronic acid and chondroitin sulfate, contributing to tissue hydration and resilience. In cosmetics, GAGs are extracted from animal tissues such as cartilage or produced synthetically through fermentation processes. They appear in moisturizers, serums, and anti-aging products, functioning as humectants to attract and retain water within skin layers. As skin conditioning agents, they promote suppleness and smoothness. Their emollient qualities soften surface irregularities, while film-forming abilities create a protective barrier to minimize water evaporation, supporting overall skin comfort in hydrating formulations.
