A blanket term used for the structural polysaccharides of the skin, such as hyaluronic acid and chondroitin. They add to a skincare product's film-forming and water-binding properties.


Glycosaminoglycans is a blanket term for a group of compounds that are a natural part of the skin, tendons, and other tissues. They are chemically related to polysaccharides, although their function is more similar to proteins. The most famous members of this group are hyaluronic acid, chondroitin, and dermatan, but there are also many others.

Depending on the manufacturer, they are either made from plant sources or from krill, shrimp, fish, and other marine animals. Their functions vary but most commonly they are used as film-formers.
