Botox for Jaw Slimming

By Vanessa Lee, RN

When people hear Botox, usually images of ironing out wrinkles come to mind. Botox is most commonly used as a cosmetic medical procedure to relax certain muscle movements that cause the skin to wrinkle for a smoother, and often times, tighter skin surface. However, there are a few off-label uses for Botox that are just as pleasing.

My current favorite as an injector – jaw slimming using Botox. Think boxy, widened lower faces transformed to a slimmer, more heart shaped face with just a few pokes of a tiny needle.

Okay, so there’s more to it than that. How does this wonderful treatment work? If you feel like you may be a good candidate for jaw slimming, make an appointment with your Doctor or Nurse Injector and they will determine if your widened jaw is due to muscle mass. If it is, then you are a great candidate for the jaw slimming with Botox. If your widened jaw is due to fat pads or natural bone structure, unfortunately this isn’t for you but weight loss or possible surgery might be your solution. Once it is determined that you are a good candidate, your injector will determine the dosage of what is needed to slim the jaw and this depends on how strong your jaw muscle, or masseter muscle, is. The injection feels like a few tiny pinches on each side of the lower face and within a few minutes, the treatment should be completed. Definitely not pleasant, but very tolerable.

I would love to say that once you walk out of the office, you are completely transformed, but not so. Botox is a neurotoxin that takes approximately 7-10 days to completely set in. So about one week for the Botox to take its full effect, and then another week for the muscle to atrophy and lose bulk. In total, it takes about 2 weeks for you to see the slimming effect. A few pokes, 2 weeks’ time and voila! You have a slimmer lower face, a softer and more feminine jaw shape, and everyone thinks you’ve lost 5-10 lbs. because of it. At least that’s what I nod yes to when people ask if I lost weight after I do this treatment on myself. Insert my angel halo here.

Although this treatment is a lot more popular in Asia, it is currently becoming more common and gaining popularity in the US. This same procedure is also used by dentists for the treatment of TMJ, when grinding your teeth at night causes tired masseters or lockjaw in the morning. The masseter muscle is injected and when the muscle atrophies, you won’t be able to grind your teeth as much at night, just another plus to thinning out a boxy jaw. Anyone who feels that their lower face seems bulky or square could benefit from this treatment, not just people who suffer from TMJ. In Southern California, where I practice, this treatment can cost anywhere from $300-$500 and the effects usually last up to 3-4 months.
