Can Botox in the jawline permanently change your face?

Thank you for your question. Botox is indicated for 3 month by the FDA. There may be residual efects for months after the treatment, until the muscle returns to form, but the msucle recovers, just like an arm muscle after a cast is removed. I hope this helps!

The effects of a single Botox treatment won't change your appearance permanently. You will look the same as you did before your treatment once the effects wear off.

Non-surgical jawline shaping is achieved by injection botulinum toxin (Botox or Dysport) to the masseter muscles.  The result is not permanent and there is no effect on facial animation.It is a very safe and effective way to contour the jawline.

Botox can make certain movements feel “funny”, but it is not
permanent and most patients get used to it quickly. If you are still concerned
about it after a month, contact the plastic surgeon that administered the
Botox.

Botox is temporary. It will last for 3-4 months and the function you are concerned about will likely improve at that time.
