What each treatment does
Chin filler addresses the central anterior chin: it can extend a recessed chin forward, lengthen a short chin downward, or square off a pointed female chin. It primarily improves the side profile.
Jawline filler addresses the lateral mandible: the gonial angle (the corner near the ear), the mandibular border between the angle and the chin, and the pre-jowl sulcus. It primarily improves the front and three-quarter view.
