Botox for mentalis strain and its adverse effect (Photo)

Question

Because I have slightly protruded teeth, weak lips and a smallish chin, I experience MS when I bring my lips together. My dermatologist suggested just a couple of units of botox for the chin, but I am really worried about the possibility of it affecting adjacent muscles, causing my mouth to droop. My question is: what can go wrong in botox injection into the chin, and why? Is it entirely technique-related, or can it migrate on its own, does it move if you sleep, talk, etc. a certain way? Thanks!

HiThanks for the question.  Botox to the mentalis muscle is very common and something I perform in my practice.  It can make a dramatic effect and create a much more relaxed look.  I included a link to my website with some photos of what you can expect.  Like with any botox injection there is always a risk of side effects.  If done by someone who knows what they are doing, with small botox doses, you should get a great result with low risk of any untoward side effects.  Good Luck

Botox is very good for mentalis strain and for any dimpling issue in the chin. Injections are always technique dependent so location and dosing are important. However , given that your physician is skilled, your chances of migration are quite slim. I would not expect your lip to droop or for you to have any untoward effects.
