Should I get Masseter Botox or Chin filler/implant? I don’t really like my side profile. (photos)

Question

Hello. I’m wondering if I need Botox or a chin implant. I don’t really like my side profile, it makes me look slightly chubby and I’m only 120lbs. I’ve also seen mixed opinion for chin implants. Also wondering if Botox and chin filler help with jaw contouring possibly?

Anna Chacon, MD, FAAD · Answer

I can understand why you’re feeling uncertain—those three options are often discussed together online, but they address different causes of an unsatisfactory side profile.

From your description (“I look slightly chubby from the side even though I’m 120 lbs”), the first thing I would think about is chin projection and jawline definition, not necessarily excess facial fat.

What Masseter Botox actually does

Masseter Botox works by relaxing and gradually shrinking the chewing muscles at the back of the jaw.

It is most helpful when someone has:

a square or wide lower face,
prominent masseter muscles when clenching,
or facial asymmetry caused by one masseter being larger than the other.

If your concern is that your profile looks soft, rounded, or lacks definition from the chin forward, Masseter Botox may not help very much. In some thinner patients, it can actually make the lower face look narrower without improving the chin or neck contour, which sometimes emphasizes a weak chin rather than fixing it.

Chin filler vs. chin implant

These two options are much more relevant for side-profile improvement.

Chin filler

A small amount of hyaluronic acid filler can:

add forward projection,
create a stronger chin-to-neck angle,
improve the appearance of a mildly recessed chin,
and make the jawline look more sculpted without surgery.

Pros:

Non-surgical
Reversible
Minimal downtime
Good way to “test drive” a stronger chin

Cons:

Temporary (typically 9–18 months)
Requires maintenance
Large amounts can look less natural over time
Chin implant

A chin implant provides permanent structural projection and is often a better option when there is true skeletal chin deficiency.

Pros:

Permanent result
More dramatic and consistent improvement
Can significantly improve the side profile and neck contour

Cons:

Requires surgery
Recovery is longer than filler
As with any implant, there are risks such as infection, shifting, or dissatisfaction with the size
Why you may look “slightly chubby”

Many people with a mildly recessed chin feel that they look heavier than they are because the chin does not project far enough to create separation between the jawline and the neck. Even at a low body weight, this can produce the impression of a small double chin or a soft lower face in profile photographs.

That is very different from having excessive facial fat.

Would Botox and chin filler help with jaw contouring?
Chin filler: Yes, often quite effectively for front-to-back jawline balance.
Masseter Botox: Only if the jaw is excessively wide due to enlarged masseter muscles.

For someone who is already relatively slim (120 lbs) and is bothered mainly by the side profile, I would generally expect chin filler to have a much greater impact on jaw contouring than Masseter Botox.

A practical way to think about it

If your profile concern is:

“My jaw is too wide” → consider Masseter Botox.
“My chin looks weak or my neck blends into my chin” → consider chin filler or a chin implant.
“I’m not sure and I want to see what a stronger chin would look like first” → start with conservative chin filler.
My overall impression

Based on your description and weight, I would be less inclined to recommend Masseter Botox as the primary treatment unless you have clearly enlarged chewing muscles. A conservative chin augmentation approach (starting with filler) is often the most informative and least invasive way to determine whether increased chin projection improves the jawline, neck contour, and overall facial balance you’re hoping for.

If the filler produces a noticeable improvement and you continue to love the look over time, then a chin implant becomes a much easier decision, because you’ll have a good sense of how additional projection affects your face before committing to a permanent surgical change.

Prior to a chin implant, I would recommend trying chin filler. This will aid in balancing your facial features. This procedure helps create a more defined jawline, which will improve your side profile. Additionally, I would recommend masseter botox to assist in slimming the face.

Personally I would say no to Botox in your chin. If you dimpling in your chin then neurotoxins would help with that. But for the recessed part of your chin, if you did not want to have surgery you could try filler in the chin for more projection. Filler can also be used for the jawline as well for definition. I would have a consultation with a plastic surgeon for advice on the chin implant then make your best, educated decision. Surgery is permanent, filler is not ( last 12-18 months).

I encourage you to begin by visiting a board certified plastic surgeon for an evaluation.  A treatment such as Morpheus8 may help improve the neckline.  If there are fatty pockets some liposuction may improve the contour.  Masseter Botox can help to slim the jawline.  Filler can be used in the chin if you are unsure about an implant.

Hello, thank you for your question, If you had external tightening discomfort, you will benefit from masseter Botox. And my recommendation is bisektomy ,double chin Liposuction, J plasma and also chin implant.
