When we refer to Dermal fillers we’re talking about Hyaluronic acid fillers acid (HA) which is a sugary, gel-like substance our body produces naturally. In the skin, HA is key for maintaining a more hydrated, plump and youthful appearance. HA fillers are created from a synthetic gel-like form of HA meant to mimic our own body’s natural HA and restore volume or rejuvenate skin when injected.
