Hyaluronic Acid Fillers
Hyaluronic acid preparations revolutionized the injectable filler market for three main reasons:
- No need for skin test
- Better durability compared to the other available biodegradable fillers and the availability of antidote (hyaluronidase).
- Immediate noticeable effect.
Hyaluronic acid, which belongs to the family of glycosaminoglycans, consists of repeated disaccharide units. The hydrophilic properties of hyaluronic acid attract water into the extracellular matrix and therefore increase the skin turgor. Hyaluronic acid is gradually degraded. In order to increase the durability of the various hyaluronic acid preparations, stabilization is usually obtained by cross-linking mostly with 1.4- butanediol diglycidyl ether (BDDE).
