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

Question

my chin pad protrudes downward when i smile, and i feel it makes my face look incredibly masculine and disproportionate. is botox a potential solution for this, or what kind of procedure would be best to fix it?

I recommend injecting 6-8 units of Botox into the Mentalis muscle to help with the prominent lower chin while smiling.

Hi Millie,
Actually botox in the chin (mentalis muscle) projects the chin anteriorly and smooths the orange peel wrinkles that occur with chin movement.  In your case I would recommend surgical reduction of your excess muscle and skin.  Before surgery you may try Botox in your chin, but I do not believe it will be the answer for your anatomy.  Consult with a board certified plastic or facial plastic surgeon.  Good luck and be well.

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.
