Dermal fillers are made with hyaluronic acid ( HA) a naturally occurring protein found normally in our bodies. It is used to add volume, create shape and hydrate the skin. The results are instant and duration of results depends on the thickness of the filler used and where it is placed. HA is degraded naturally over time by enzymes present in our body. This enzyme also allows medical professionals to be able to dissolve fillers for corrective treatments.
