What procedure is most effective and recommended for slimming and enhancing the lower face/jawline on a round, undefined face?

Hi pastel_buttercup :)I understand you wanting a slimmer V-lined shaped face. It has always been popular here in Asia. First of all, I am sorry I cannot give you the best answer since I cannot see your face at the moment. Also it is better for a physician to do a thorough examination on your face in person. So he/she can assess your overall face, facial muscles, skin laxity, bone structure, facial fat and so on. There are actually many ways to make your face look slimmer - botox, fat dissolving injections, energy based devices, thread lifts, fillers and so on. But since you asked about masseter botox, here is a way to know if it may be helpful to you. If you do have bulging muscles when you bite down hard and you can palpate them on the both sides of the angles of your chin, it is somewhat effective to get masseter botox - however it will make your face look slimmer on both side so it may help with the overall contour on the outer side of your face - just making your face look smaller in width. Yet if you want that V line shaped look we need to assess you chin and overall contour of the U line at times and some chin filler may help to create that slimer look. Also some people have a tight mentalis muscle making there chin look somewhat tense and shorter. So a mentalis muscle botox can help as well. I hope this helped. Also don't forget you look beautiful just the way you are :) Good luck !

Masseter Botox injections will help slim your lower face. Injecting a filler such as Voluma will help elongate your lower face. Two treatments combined will help you achieve a heart shaped lower face you desire.

Hello,

Thank you for your thoughtful question—it's great that you're considering both your aesthetic goals and long-term facial balance at your age.

For patients with a round, wide, or less-defined lower face who want to achieve a slimmer, more contoured appearance (such as a V-line or heart-shaped face), there are several non-surgical and surgical options to consider. Since you're looking to maintain a youthful look and avoid buccal fat removal, here are the most effective and recommended treatments:

1. Masseter Botox
This is an excellent non-surgical starting point, especially if you have hypertrophy (enlargement) of the masseter muscles. It works by relaxing the muscle, which gradually slims the lower face over several weeks to months. It's safe, temporary, and helps create a narrower jawline without compromising natural fullness elsewhere in the face.

2. Chin and Jawline Filler
Dermal fillers can enhance and elongate the chin or improve jawline definition, creating the illusion of a slimmer, more structured lower face. This is a customizable and reversible approach that works well for balancing proportions without surgery.

3. Kybella or Deoxycholic Acid Injections
If there is any submental fullness (under-chin fat), Kybella can help contour this area. It permanently dissolves fat and enhances jawline definition when performed carefully.

4. Skin Tightening Treatments
Radiofrequency (RF), ultrasound (like Ultherapy), or microneedling with RF can help tighten mild skin laxity and add contour to the face—especially useful if you're avoiding surgical intervention.

5. Surgical Options (If Considering Later)
While reconstructive jaw surgery (orthognathic surgery or genioplasty) is an option for certain structural issues, it's typically reserved for more severe asymmetry or bite concerns. At 19, you're likely still a good candidate for non-invasive treatments first, especially since your facial bone structure is still maturing slightly.

My Recommendation:
Start with a consultation for masseter Botox and possibly chin/jawline filler to enhance facial harmony non-surgically. This approach is subtle, balanced, and ideal for someone your age who wants to avoid drastic or irreversible changes while still achieving a more defined look.

You're definitely on the right track! Achieving the desired look often requires a combination of approaches tailored to the individual's face shape. Each technique contributes uniquely to the overall result. Thinning the masseter muscle with Botox and enhancing the chin with filler or an implant are highly effective methods. For individuals with fullness in the buccal area, a conservative fat pad reduction can refine the facial contour without creating an aged appearance. Additionally, neck liposuction or jawline liposuction, combined with fillers along the jawline, can help sharpen and define facial features for a more sculpted look.

Botox is an effective and safe treatment that can be used to slim the lower face/jawline while also alleviating symptoms related to TMJ -- (clenching, jaw pain, headaches etc....) Please see the supporting link below:

Without photos, I can only comment in the most general terms. Botox has been used for years for slimming a hypertrophic masseter muscle, reaulting in a marrowing of the lower face and hence a generally more desirable, feminine, oval face shape.
Robust HA contouring fillers can additionally be used, if properly injected along the base of the jawline by a very experienced, board certified cosmetic dermatologist filler expert, to better define and straighten the jawline and additionally add length to the face in profile.
Consultation with an experienced physician injector would be strongly advised if you wish to avoid the expense, risks and extensive downtime of invasive, aggressive surgery. Hope this helps and best of luck.

Great question! I would recommend cosmetic injectables to achieve this look. Botulinum injections to the masseter muscle every 3-4 months can produce a slimmer lower face which is usually quite pleasing.

You will likely have the best results from a combination of treatments. Botox to the masseter muscles can help slim the jawline. Fillers like Juvederm Volux are specially designed to help contour the jawline. Other treatments such as Morpheus8 can address overall skin tone and texture. Vist my website or a provider near you to learn more.

Its a challenging question to answer without seeing a current picture. Most people seek to go from elongated to round which is largely accomplished with filler. Masseter botox can weaken the masseter muscle and reduce the bulk if indeed that is the cause of the roundness that you are seeking to change.

Hi,Usually the best way to decide on the procedure that helps you achieve jawline slimming & definition, is by evaluating your face in an in office appointment to go over your whole facial soft tissue, hard tissue & teeth. But generally speaking if you have Masseter muscles/ jaw muscles hypertrophy, you can get Botox (or other neuromodulators) for the Masseter muscles to relax the tension & bulkiness in the muscles, combined with biostimulating fillers in the jawlines to define your jawline & to give you more facial balance. This is a non invasive approach & if done properly, would give you natural looking results. Hope that helps!Best of luck. Dr. Dema Hilmi
