YouTube short (Shereene Idriss) advising on masseter Botox: avoid masseter Botox if you have a weak or dainty jawline—especially if 40+—because reducing masseter muscle bulk can worsen jowling; consider a night guard and reserve Botox as a last resort. Botox may be appropriate for people with strong, pronounced jawlines who clench frequently.

Masseter. Botox is great if you are somebody who has like a cure nightly jawline or your jaw is really pronounced. Now if you're like me and you have a weak jawline, like this is a weak jawline. Okay, weak jawline. Never put Botox in your masseters because the second that these babies go down you might become jowlier because you have less of a support holding your jawline up. Now if you have a strong jawline and you are somebody who clenches a lot, then botox them. Enjoy. But if you have dainty jawline, especially as you are 40 plus and you are somebody who clenches a lot, I pick vanity over comfort. I would keep those muscles intact and I would not botox them and instead I would get a night guard or I would try to use my night guard if you do have a night guard. But I would really save the Botox as a last resort because you might get jolly and that might be the price that you actually pay and not the financial price for the Botox.
