What Are Dermal Fillers?
Most dermal fillers used today are biodegradable and biocompatible materials which are injected into various levels of the skin to produce a volumising and/or stimulatory effect on the tissues.
Hyaluronic acid gel is one of the most popular dermal fillers being used today. Being a building block of collagen in the body, HA is extremely biocompatible. By varying the type of cross-linking (a chemical process) in the material, the same material can be turned into a high viscosity or a low viscosity product. The viscosity of the product will determine the amount of lift and the stability of the structure.
Another huge advantage of HA is that the material can be rapidly dissolved by injecting the enzyme hyaluronidase. Thus, mistakes can be corrected.
