Dermal Fillers (Hyaluronic Acid) Injection Hyaluronic acid molecules are non-sulfated glycosaminoglycans: polysaccharides which are present in the extracellular matrix of the dermis and epidermis. They are synthesised by keratinocytes (epidermis)and fibrobiasts (dermis). Hyaluronic acid molecules are non-species and non-tissue-specific so there is little risk of allergy. Hyaluronic acid molecular structure is three-dimensional (3D), occupying a very large volume for its molecular weight. The molecules form a dense, complex mesh. The water-retaining capacity of hyaluronic acid helps maintain the cohesion and structure of the dermis. It hydrates the skin, making it supple and firm and providing visco-elastic properties. Use
