After Botox, jawline and cheeks are sunken (Photo)

The good news is, the results from BOTOX® and any other neurotoxin are
not permanent, so any results you’re not pleased with will go away over time.
Unfortunately, there’s no way to “undo” results from BOTOX® or speed up the
time it takes for your body to metabolize it. Injecting BOTOX® requires
precision to deliver the best result that meets the patient’s goals. If you’re
unhappy with this result, I would recommend talking with your doctor to explain
your concerns and adjust injection sites for your next treatment.

I've used Botox to shape and narrow the jawline for years. We generally don't see a change in the cheeks after Botox. In contrast, by reducing the size of the jaw muscle appropriately, our patients have reported that the cheeks may appear relatively fuller. If you haven't already, then speak with the plastic surgeon or dermatologist who provided your Botox treatment. Unlike some facial fillers, one can't reverse Botox. Fortunately, if you feel the cheeks have sunken after Botox, then waiting a few months for the Botox to wear off will resolve the issue.Best,Dr. Chaboki

Botox is used for masseter hypertrophy; the decreased tone in the muscle leads to less bulk at the lateral jawline.  However, decreasing volume of the muscle can have an effect on surrounding areas.  Unfortunately, there is no way to reverse the effects of botox, but thankfully it is short lived and will fade with time.  Return to your doctor for evaluation as some botox may be able to be used on the left to create symmetry.

I'm not quite clear why you got Botox. There is nothing to reverse Botox. Effects are only temporary. I would never inject uneven amounts of Botox on each side in the masseters because this can cause undue stress on the joints and affect the alignment of the teeth. Waiting it out for about 4 months will get things back to normal.

Usually botox does not impact the master muscle so quickly. Often it requires several treatments for the muscle to shrink.  The botox will wear off and likely the masseter will  become more prominent.

It seems that this is related to masseter muscle reduction. The result will wear off in 3-4 months.BestDr. Karamanoukian#RealSelf100 Member

Thank you for your question.  You are seeing a reduction in the bulk of the masseter muscle, as well the masseter atrophy is not symmetrical so you may wish to return to your physician to have additional botox injected to correct the asymmetry.  Botox is not reversible and the effect tends to last for a few months.  Masseter injections are commonly done to thin out a square jaw.  Regards, Dr. Matt Elias
