Great question! While on the surface, both neuromodulators and dermal fillers seem very similar, which is why many people tend to get the two types of injectables confused. The best and easiest way to describe the difference between the two is this: Neuromodulators (like BOTOX) will limit the movement of a targeted facial muscle, while dermal fillers are used to improve volume.
While both types of injectables can reduce wrinkles and persistent lines (i.e. crows feet, persistent frown lines, Perioral lines or "smoker's" lines, dimpled chins, etc.), dermal fillers fill in the troubled areas with a gel, usually made of Hyaluronic Acid, that will build up volume in your face and certain areas of your body.
