Soft, gentle with the perfect V-shape – that is what a feminine face should look like. But have you ever felt that you look too masculine because of your square jaw?

While some consider having a more pronounced jawline as a “flawsome” feature, however others think that it can throw off the balance of their facial profile.

Contrary to what most people believe, having an angular face shape is not entirely inborn. Some actually develop it over time as they overwork their jaw muscles or masseter muscles. This leads to a condition called masseter hypertrophy where one or both the masseter muscles become enlarged. This can be caused by excessive chewing, clenching and grinding of the teeth. The muscles in your jaw area work similarly to the rest of your body. The more it gets worked out, the more developed it becomes.

One might think that the only solution is to have it surgically contoured, but injections can also help shape it to some degree.

Here are the commonly asked questions when it comes to enhancing the shape of your jaw with a non-surgical Square Jaw Reduction.

Frequently Asked Questions (FAQs)

1. What are the available treatments to reduce the size of a square jaw?

The reduction of a square jaw to create a V-shape can be achieved using surgical and non-surgical methods. Surgical jaw reduction involves an incision inside the mouth to remove the outer layer of the enlarged mandible or jawbone, narrowing the contours of the jaw. However, this can involve complications like the loss of sensation on the lower lips and teeth.

On the other hand, the non-surgical Square Jaw Reduction procedure involves a simpler process of injecting a measured amount of solution to relax the jaw muscles. This weakens the masseter muscle, which reduces its size over a period of time.

2. How is the non-surgical Square Jaw Reduction procedure performed?

Your doctor will initially assess whether you are a good candidate for a non-surgical Square Jaw Reduction procedure. After your thorough evaluation, few tiny injections will be administered to predetermined areas of the jaw. This will help relax the jaw muscles, reduce it in size and make it slimmer.

3. Who are the ideal candidates for a Square Jaw Reduction procedure?

The non-surgical Square Jaw Reduction procedure is ideal for patients who have a prominent jawline due to masseter hypertrophy. The treatment, however, is not appropriate for those who have a pronounced jawline due to an enlarged mandible or jawbone. In this case, the surgical method may be recommended.

While a V-shape and contoured face is sought after among women, the non-surgical Square Jaw Reduction treatment can also be done on men who also wish to balance their facial features.

It should be noted that pregnant and breastfeeding women, as well as individuals who have dental conditions and neuromuscular disorders, are advised against the procedure.

4. What is the expected result?

The procedure can help reduce the size of the masseter muscles (Smyth 1994). This results in a refined and softer V-shaped contour to the face that will harmoniously balance your other facial features. With the right aesthetic skills and eye for detail, the reduced jawline result will come out looking natural.

5. Is Square Jaw Reduction painful?

The treatment will only involve a mild stinging sensation as the solution is being injected to the treated area. This is a tolerable procedure that will not require any anaesthetic.

6. How long will the procedure take to perform?

One advantage of this procedure is that it doesn’t take long to finish. In some cases, it can be done in 10 minutes depending on the area to be treated. However, your doctor will focus more on administering the solution properly, rather than completing the procedure within a certain time frame. This is to ensure that the desired outcome and result can be achieved.

7. When will I see the result?

The desired outcome is gradual. You will see noticeable results two to three weeks after the procedure (Klein 2014). However, the ideal results will only be visible six to eight weeks after your treatment. By this time, the masseter muscles have fully relaxed.

8. Is there any downtime or recovery period?

Since the procedure is minimally-invasive, you can return to your normal daily routine after the procedure.

Minor swelling and redness on the treated areas may be observed after the treatment, but this will eventually subside after a couple of hours.

9. How many treatment sessions do I need?

Generally, one treatment session is needed to effect the desired results, with each patient requiring different amounts of the solution to be injected.

The doctor will recommend when a return treatment will be necessary, and how often this will be.

10. Is the result permanent?

Unfortunately, the result of a non-surgical Square Jaw Reduction procedure is temporary. However, it is long lasting. Results last for about six months or even longer. Touch-up treatments may be needed to maintain the results.

11. Can this be performed with other aesthetics procedures?

If you want to create a holistic improvement, you can complement a non-surgical Square Jaw Reduction procedure to further enhance your facial features with Dermal Filler treatment. This can help shape and contour your nose, chin and lips to harmonize with your new V-shaped face. Additionally, Thermage CPT is also an ideal complementary procedure, which helps to tighten loose skin on your face and body.


During your consultation, Dr. Tyng Tan will make a thorough evaluation of the jaw. This allows her to carefully study the overall facial structure. This also gives her a better picture on the proper dosage of filler injections to achieve a natural-looking and well-proportioned face. A personal consultation will also allow her to properly determine the total cost of a square jaw reduction treatment based on the number of units needed.
