Will botox help keep my chin from sticking out when I smile? (Photos)

Botox (botulinum toxin) can help reduce chin protrusion when smiling if the issue is due to overactivity of the mentalis muscle. The mentalis muscle, located in the chin, can cause the chin pad to protrude or dimple when it contracts, especially during expressions like smiling. Injecting botulinum toxin into this muscle can relax it, leading to a smoother and less prominent chin appearance during facial movement[1].

However, if the chin protrusion is due to underlying bone structure or significant soft tissue volume rather than muscle activity, botulinum toxin alone may not be sufficient. In such cases, other procedures—such as dermal fillers (e.g., hyaluronic acid fillers like Restylane or Juvederm) to balance facial proportions, or surgical options like genioplasty—may be more appropriate.

A thorough assessment by a provider experienced in facial aesthetics is essential to determine the exact cause of your chin protrusion and the most effective treatment. If the mentalis muscle is the primary contributor, botulinum toxin is a minimally invasive and effective option. If not, alternative or adjunctive procedures may be recommended.
