What can help to slim down lower face area and give a more defined jawline? (Photos)

Hello! I’m Lauren, the aesthetic injector here at Colorado Plastic Surgery Center. If you're looking to slim the lower face and define your jawline, a combination of TMJ Botox and Volux filler can really help. TMJ Botox relaxes the masseter muscles (especially if they're overactive), which can slim the face over time. Volux is a dermal filler designed specifically for the jawline and chin area, it adds definition and structure.

There are several effective, non-surgical ways to refine the lower face and create a more defined jawline. The right approach depends on whether fullness is coming from muscle, skin laxity, or volume distribution. • Masseter Botox: If the lower face looks wide due to strong chewing muscles, relaxing the masseters with Botox can slim and taper the jawline. • Advanced Skin Tightening (Morpheus8 or other RF microneedling technologies): These treatments stimulate collagen, tighten skin, and reduce heaviness along the jaw and under the chin, helping sharpen definition. • Dermal Fillers for Contour: Placed strategically in the chin or jawline, fillers can lengthen, project, and balance the profile — making the lower face look slimmer and more sculpted. • Combination Approach: The best results often come from combining therapies — for example, masseter Botox to narrow, paired with skin tightening and filler for contour.
A consultation is essential to determine if your main concern is muscle activity, skin laxity, or volume balance. From there, a customized treatment plan can be designed for the most natural and defined result.

Liposuction to get a sharp jawline and get rid of those nasty jowls followed by facetite RF and morpheus to tighten up the skin a lot all done at once under local is your best option. Cost is roughly on special for $5000 and so easy to undergo with quick results.

Full face frontal and profile views in repose (not smiling or emoting) would have provided more information to creating an appropriate nonsurgical treatment plan.
Generally speaking, however, robust HA volumizing and lifting fillers can be used to create a more oval, heart-shaped face (a nice Ogee Curve) when injected properly by an expert in the upper outer cheeks region. Additionally, a robust HA contouring filler injected properly in the region of the angles of the jawline can help to better define and straighten the jawline and diminish jowling along the jawline.
Botox injections spaced evenly along the jawline and the upper neck can help to further tighten the jawline and upper neckline. in the hands of an expert injector all of the foregoing can be performed in under 30 minutes. The results are typically immediate and the treatments engender little to no significant downtime and My last patient yesterday had all of this and more performed in one treatment session and left for a business meeting two hours later.
You would be wise to make sure to consult with a board certified cosmetic dermatologist injection expert and best of luck.

Thank you for your question and photos. When it comes to contouring a round face and enhancing the jawline, a combination approach often provides the most natural and satisfying result. Based on your features and concerns, here are some treatment options to consider:

1. Jawline and Chin Filler
What it does: Adds structure and definition, especially if the jawline is soft or lacks natural angles.

Ideal for: Creating a sharper contour and balancing facial proportions.

Results: Immediate, with minimal downtime.

2. Masseter Botox
What it does: Slims the lower face by relaxing the masseter muscles (the muscles used for chewing).

Ideal for: Those with a wide or square face shape due to muscle bulk, or those who grind their teeth.

Results: Noticeable slimming of the lower face in 4–6 weeks, subtle but effective.

3. Jowl and Pre-Jowl Filler or Skin Tightening
What it does: Addresses early jowling or sagging in the lower face, which can blur the jawline.

Options include: Hyaluronic acid fillers, or collagen-stimulating fillers like Radiesse or Sculptra in strategic areas.

Other options: Radiofrequency (RF) skin tightening or ultrasound-based devices (like Morpheus8, Ultherapy) can also help tighten loose skin.

4. Submental/Lower Face Contouring
You’ve already tried Kybella—great start. If the issue is more skin laxity than fat, it may be better to explore skin tightening devices or thread lifting for a subtle lift.

5. Neck and Jawline Synergy
The neck and jawline are closely connected aesthetically. Treatments like neck Botox (Nefertiti lift) or RF microneedling can tighten skin under the chin and along the jawline, improving overall definition.

Before You Spend:
It’s important to assess whether fullness is due to fat, skin laxity, or muscle bulk—this will guide the best treatment plan.

Filler adds volume, so if the main concern is excess volume or puffiness, it needs to be used strategically and sparingly to contour rather than bulk.

Conclusion:
For your goals, a combination of jawline filler, masseter Botox, and possibly skin tightening would likely deliver the best facial slimming and definition. Always opt for a provider who can tailor the approach to your anatomy and goals.

The best treatment depends on your anatomy, skin quality, and age. Fillers can enhance contour in certain patients, but they generally will not slim the lower face and can sometimes make it look heavier. Botox only helps if the masseter muscles are enlarged, which does not seem to be your main concern.
If your fullness is due to fat, submental liposuction can provide definition. If there is also loose skin or jowling, then a neck lift or a combination of a lower facelift with a neck lift may be the most impactful option. The right choice can only be determined through a thorough in-person examination by a board-certified plastic surgeon, who can guide you to the treatment best suited to your anatomy and goals.

You can consider Masseter Botox to help slim the appearance of the lower face. Fillers such as Volux which are designed for the jawline can help with contouring. Other options such as Morpheus8 use RF technology combined with microneedling to improve overall skin tone and texture. I've included a video that I hope you find helpful.
