Many people feel self-conscious about a broad or square jaw, especially when it affects facial balance or the way the face looks in photos. Jaw slimming injections offer a non-surgical solution to soften the lower face by gently relaxing the muscles that make the jaw appear prominent.
Every treatment is tailored to your unique facial structure and performed by a SMC registered doctor, ensuring safe and natural-looking results that add to your confidence.
The masseter muscles are located at the sides of the jaw. They contribute to chewing and can become enlarged through too much activity or genetics. When there is excessive muscle bulk, this may create a squared jawline or a heavier lower face appearance.
Jaw slimming injections work by temporarily reducing the activity of these muscles using neurotoxins. As the muscles relax, the jawline gradually appears narrower and the lower face contour becomes softer.
The injections offer a non-surgical approach to improve the appearance of a broad or square jaw, with benefits including:

The treatment is generally well-tolerated, but as with any medical procedure, there are potential risks. This may include:
From the initial assessment to the moment you leave the clinic, each step is carefully planned to ensure comfort, precision and natural-looking results.
Before any injections, a consultation is conducted to assess your jaw muscles, facial symmetry and overall proportions. Our doctor will review your medical history, discuss your aesthetic goals and explain the procedure in detail. This includes potential side effects, expected results and any complementary treatments that may enhance the outcome. The consultation ensures that the treatment plan is personalised and suited to your anatomy.
During the procedure, fine needles are used to inject precise doses into the masseter muscles. The session is brief, usually taking only a few minutes per side. Localised discomfort is typically mild and temporary. Our doctor carefully marks out injection sites to ensure even results, minimise risks and maintain natural facial expression throughout the process.
Immediately following the procedure, mild swelling, tenderness or slight redness may occur around the injection sites. These effects are usually temporary and resolve within a few days. Most patients can resume their normal activities after an initial period of strictly no facial massage, strenuous activities or steam room/saunas following their treatment .

Adhering to post-treatment care is essential to let the jaw muscles relax well without compromising treatment effects as well as ensuring that no complications can happen.
After jaw slimming injections, patients may be advised to:
These measures help ensure the injections settle effectively, reduce the risk of temporary asymmetry or swelling and allow the lower face to gradually adopt a softer, balanced contour.

Jaw slimming injections work gradually, as the masseter muscles slowly relax over time. Patients can generally expect:
The effects of jaw slimming injections are temporary and some individuals may require repeat sessions to maintain the desired contour. In general, treatment frequency may include:
