Hydrolyzed glycosaminoglycans are enzymatically or chemically broken-down GAGs (such as hyaluronic acid and related polysaccharides) used in skincare to bind water and improve skin hydration and surface smoothness. The smaller fragments are intended to aid absorption and provide moisturizing, conditioning benefits.
