What is jaw (masseter) Botox?
The masseter is the thick muscle at the back of the jaw that you use to chew and clench. In some people it becomes large, making the lower face look wide or square. Jaw Botox relaxes this muscle, and as it is used less forcefully it tends to slim down gradually, softening the angle of the jaw. It is one of the most requested treatments in Gangnam, and at Live Young Clinic it is planned as part of your overall face shape rather than as a standard dose for everyone.
Who is a good candidate?
Jaw Botox tends to suit people whose jaw width comes largely from muscle, which you can often feel as a firm bulge when you clench. If width comes mostly from bone or from fat, Botox alone may have limited effect, and Dr. Song may discuss other contouring options such as filler or lifting. Some people who clench or grind their teeth also ask about it; Dr. Song will explain what can realistically be expected.
- Firm masseter bulge when clenching
- Square or wide lower face
- Interest in a softer V-line without surgery
How Dr. Song plans a natural, balanced jawline
Needs Mapping begins with feeling and observing the masseter at rest and during clenching, and considering bone structure and skin thickness. Over-slimming can make the cheeks look hollow or the skin look loose, especially in thinner faces or in people in their 40s and beyond, so Dr. Song also thinks about how your face will age over the next decade. The Curated Plan sets precise injection points and doses, and Dr. Song places each one herself in 0.1-unit steps. Sometimes jaw Botox is paired with filler at the chin or lifting to create a more three-dimensional contour.
Recovery, results and aftercare
Most people return to normal activities soon after. Some notice mild tiredness when chewing tough food for a while. Unlike wrinkle Botox, the slimming effect develops slowly over weeks as the muscle reduces. Avoiding massage of the area and intense heat or alcohol for a short time is commonly advised. Because the effect is temporary, many people plan repeat sessions; Dr. Song will suggest timing that suits you.
Why visit an English-speaking doctor in Apgujeong, Gangnam?
Jaw contouring depends on judging where width really comes from. At Live Young Clinic, Dr. Song examines you personally and talks you through her reasoning in English. The Apgujeong clinic is close to Apgujeong Station (Line 3) and around six minutes from the Seoul Express Bus Terminal, making it easy to reach from elsewhere in Gangnam.
Frequently asked questions
How long until I see a slimmer jaw after Botox?
The slimming change is gradual because the muscle has to reduce in size, so it typically develops over several weeks. Timing varies from person to person, which is worth keeping in mind if you are visiting Seoul briefly.
Will jaw Botox affect my chewing?
Some people notice mild fatigue when chewing hard or chewy foods for a while after treatment. Normal eating is generally unaffected. Dr. Song adjusts doses carefully to balance slimming with comfort.
Can jaw Botox help with teeth clenching?
Some people with strong clenching habits ask about masseter Botox. Whether it is appropriate depends on your situation, and Dr. Song will discuss this at consultation and may suggest you also see a dentist.
Could my cheeks look hollow after jaw Botox?
Over-treatment in a thin face can sometimes cause a hollow or loose look. Dr. Song assesses bone structure, skin thickness and age-related changes before dosing so that the contour stays natural.
Can I combine jaw Botox with chin filler?
Yes, combining can help create a more balanced V-line. At the Apgujeong clinic, Dr. Song plans Botox, filler and lifting together when that suits your face. She will explain the order of treatments and what aftercare each one needs.
