Reduce Chin / Mentalis Size with Botox or Dysport?

Botox and Dysport will paralyze muscle and help promote some atrophy, or decrease in size. This can work on a large chin, assuming that the bulk is truly sue to muscle bulk and not just large bone. Keep in mind that the reduction can take 4-6 months to be seen and may take a few treatments.  Also, injecting into this area may have some slight effect on the fine movement of your mouth. 

Thank you for your question. Neuromodulators like Botox can be injected into the masseter or the mentalis muscles, relaxing them and reducing their size. This treatment should only be performed by an experienced, board-certified injector who has the expertise and precision to achieve a natural result. I encourage you to schedule an in-person assessment to discuss your concerns and goals. Through this meeting, your injector can design a customized treatment plan to meet your needs best.

Neurotoxins works well to give a smoother appearance to the chin by relaxing the muscle. Usually 10-15 units of Botox will be sufficient. The product is in full effect in two weeks and gradually wears off over 3 to 4 months.

When Botox or Dysport is injected in to the chin area, it can result in a nice smooth chin.  It does this by relaxing the muscle.  Usually 10-15 units of Botox is enough to have this effect.    

In NYC with a prominent chin, see Dr. Barry Zide.  Besides being a great guy, he's a world recognized expert in the evaluation and management of the prominent chin.

Hello!
Dysport will paralyze the muscle, and or decrease the size of the chin. It helps to control the dimpling and bulk in the chin. As we age the chin starts to protrude. This is a treatment that would need to be maintained every 3-4 months in order to see results.

Botox and Dysport can be safely injected in the lower part of the chin to relax the mentalis muscle and create overall smoother skin in the chin area, with less pebbling and dimples. A total amount of 10 to 15 units of botox should accomplish this. When using Dysport in this area, I use a relatively smaller amount because of dysport's greater diffusion, typically 30 units maximum (equivalent to 10 units of Botox).

The mentalis muscle, the muscle that makes the chin dimple, and helps control your lower lip strength and movement, can be weakened with Botox, but in order to cause the atrophy and reduction of muscle size that you may seek, a significant amount of Botox would have to be injected, AND MAINTAINED, for months and months and months, to see a visual difference.

The amount of Botox this would require, over that amount of time, holds a significant risk of weakening your ability to properly eat, drink, and speak. Believe it or not, that mentalis muscle does a lot for you every day that you are not aware of.

If you are going to pursue shrinking it, try smaller doses first, to make sure you can tolerate the effects.

Botox and Dysport can reduce the size of the chin muscle. It is best used to treat that "pebbly" look to the chin but can reduce some of the muscle bulk as well. It may not be perfect, but might be helpful.

While you are correct that Botox injections can reduce the size of the masseter muscle, it is unlikely that will work the same for the mentalis muscle. The masseter and the mentalis muscles are composed of different types of muscle fibers and are quite different in size and function. The masseter is a functional chewing muscle, the mentalis is largely a muscle of facial expression. Muscles of facial expression do not seem to shrink with Botox injections given the millions of people who have had forehead and glabellar injections and no one yet has seen those muscles permanently stop working because they have shrunken down in size. It is also important to realize that the 'ball' of tissue you have on your chin is more than just muscle and it is unknown what is the contribution of muscle to your soft tissue ball. Its size alone may not be the bulk of what you are actually seeing.
