Jawline filler is an injectable hyaluronic acid-based treatment placed along the jawline to improve definition, structure, and lower-face balance. It can help create a more contoured appearance, improve soft jawline definition, and enhance the transition between the chin, jawline, and neck.

Depending on your anatomy, jawline filler can be used to add subtle structure where the jawline lacks definition, improve side-profile balance, or support the lower face when there has been mild volume loss or softening over time.
