Would Botox help this ‘ball’ in my chin and my wide jaw? (Photos)

Question

I’m very slim at 49kg but I have this large fatty chin and wide jawline, would Botox help this issue. It’s like there’s a golf ball under my chin, especially when I smile, it like a giant U.

Based upon the photos you submitted, I think you can help your "fatty chin and wide jaw" by considering possibly 2 things.  You would benefit from a dermal filler ie Restylane around the borders of the chin near the jawline to soften the contrast of the chin to the jawline (no the filler will not make your chin bigger).  This essentially helps to hide the chin so it is not so obvious and it would blend the chin to the jawline.  You may also benefit from some Botox in the chin itself.  It may soften the appearance of the chin. This concept will have to be evaluated in person. Please consider an in person consultation for better explanation and demonstration of the possible outcome.

hello and thank you for your pictures. Although Botox can be a temporary help to slim wide jaw but there are more treatments that can help reducing the under chin fat for a longer period of time and provide a nice jaw definition. Agnes Ultra RF Microneedling is a safe nonsurgical technology help to reduce the fat and tight the skin and the effect will last much longer than Botox.

From your photos it seems there is pinchable fat with good skin quality. Submental liposuction is the most effective and predictable option. An in person exam should confirm that the fullness is fat rather than gland or muscle.
Wishing you a smooth plan ahead.

Hello! My name is Holly Frandsen and I'm an aesthetic nurse injector at Amadi aesthetics plastic surgery. Looking at your areas of concerns, there are three procedures you could consider. You could look into dermal fillers to help blend the areas of your chin and to slight pull the chin out. You could also consider neuromodulators such as Botox or Dysport to help any dimpling in the mentalis muscle of the chin. This would help relax the mentalis muscle from pulling upward and would help dimpling or any "orange peel" appearance. Lastly, I can't see your side profile but if you feel like the "ball" under your chin could be fat, you could consider liposuction.

If by "ball in your chin," you mean that when you smile, your chin stands out like a ball surrounded by and highlighted by a recess on each side, then the use of an HA volumizing filler properly injected along the jawline into the regions of these depressions can elevate them to extent that a smoother transition between the chin and the surrounding jawline is created. 
Frankly, I would suggest that a small amount of saline solution or diluted anesthetic solution be first used (before any actual treatment is performed) as a test to see whether the resulting smoothing achieves a satisfactory result. If so, then actual treatment with the HA filler can be performed. Hope this helps and best of luck.

From the photos you shared, it looks like the fullness under your chin is more likely related to soft tissue or fat rather than muscle. Botox works by relaxing muscles, so it can be very effective for reducing the size or prominence of the masseter muscles (the muscles that can widen the jaw), but it won’t reduce fat or a “ball-like” fullness under the chin.

The “golf ball” appearance you notice, especially when you smile, is probably due to a combination of small fat deposits and underlying structural tissues. Treatments like Kybella, CoolSculpting, or targeted liposuction are generally more effective for reducing fat in that area, while Botox can help soften a wide jaw if the masseter muscle is contributing.

So, Botox alone would likely improve jaw width slightly if the masseters are large, but it won’t address the fullness under your chin. A tailored approach combining different treatments would be needed for the smoothest result.

What you’re describing actually sounds very common, and it doesn’t usually mean you have extra fat there, especially since you’re quite slim. That “golf ball” look under the chin when you smile is often caused by a strong mentalis muscle contracting, not fatty tissue. Botox can work really well in this area by relaxing that muscle, which helps smooth the chin and soften that U-shaped bulge when you smile. It won’t remove fat, but it often makes a noticeable difference in how the area looks at rest and in motion. A quick in-person exam can confirm this and make sure Botox is the right option for you.

This is a very common concern, and you’re describing two different issues that often show up together, which is why a multi-modality approach is so important.
That “golf ball” or U-shaped bulge under the chin when you smile is often caused by overactivity of the mentalis muscle, not excess fat. In those cases, Botox can be very effective at relaxing the muscle, smoothing the chin, and reducing that puckering or balling effect when you animate.
As for the wide jawline, if this is due to strong or hypertrophic masseter muscles, Botox can absolutely help soften the jawline over time by reducing muscle bulk. This is especially common in slim patients and those who clench or grind. Overtime, with relaxation of the muscle, the muscle begins to atrophy which means it gets smaller. It does take about 2 to 3 times but eventually can lead to aesthetic facial slimming with Botox injections into the masseter muscles.
However, if there is true submental fat or tissue laxity, Botox alone will not address that. This is where a multi-modality approach becomes essential. Depending on anatomy, that may include treatments such as fat-dissolving injections, skin-tightening devices, or other non-surgical options, sometimes combined thoughtfully with Botox for the most natural result. Sometimes depending on anatomy, filler placed in just the right places can actually create a slim effect if added strategically in areas around your area of concern to give balance and slimming.
The key is an in-person assessment to determine what is muscle, what is fat, and what is skin. When treatments are layered strategically, we can create balance and refinement without overdoing any one thing.
Aesthetic treatments should always be discussed with and performed by a trained, licensed, and medically certified aesthetic provider. The recommendations above are for educational purposes only and do not replace an in-person consultation, examination, or personalized medical advice.
