Facial fillers are gels made of hyaluronic acid. Unlike neuromodulators, they do not have a physiological effect on muscles and wrinkles, but instead are used to add volume to areas of deflation or hollowing and to provide a lifting force to soften lines in the face.
Types of dermal fillers
There are many different filler brands and products within each brand. Fillers differ in how stiff the gel is, how much water they absorb, how much lift they provide, and whether they cause inflammation. All hyaluronic acid fillers are dissolvable, but removing filler typically requires several sessions.
