Jaw Botox 50u

• The muscle at the side of your jaw stands out firmly when you clench
• Your lower face looks angular or wide from the front
• You’ve been told you have a habit of clenching your teeth

Jaw Botox doesn’t change the shape of the bone. For teeth grinding or jaw joint pain, dental care may need to come first.

• 01

  Where you are now, and where we start

  Whether the reason your lower face looks wide is the thickness of the chewing muscle (masseter), or bone or fat

• 02

  The change you want, the impression you keep

  If the jaw looks wide because of bone, a muscle injection makes little difference, so we see how much the muscle stands out when you clench.

• 03

  How it differs from similar options

  If the area below the ears or under the jaw is soft and full, it may be the salivary glands rather than the muscle; in that case we discuss Salivary Gland Botox separately.

  Health information and recovery schedule

  If your cheeks are naturally slim, the side of the cheeks can look hollow as the muscle shrinks, so we set the dose conservatively.

Jaw Botox doesn’t dissolve the muscle — it makes it thinner by having it used less.

The masseter is used every time you chew food or clench your teeth, and it can thicken depending on your habits. When botulinum toxin reduces this muscle’s contraction, its thickness decreases over several weeks in proportion to how little it is used. A study that measured the masseter with 3D CT reported that muscle volume decreased and then returned to its original state at around 6 months. That is why the change shows not right after the injection but several weeks later, and maintaining it requires repeat treatment.

How it works

• 01

  Feeling it while you clench

  When you bite down on your back teeth, the masseter rises firmly below and in front of the ear. We confirm this area by hand and place the injection points only within the muscle.

• 02

  Left–right differences

  Depending on chewing habits, the muscles on the two sides can differ in thickness. If there is a difference, the amount used on each side can differ.

• 03

  Avoiding the smile muscle

  A muscle that pulls the corners of the mouth sideways runs in front of the masseter. If injections drift forward, your smile can change, so we mark the front boundary so it isn’t crossed.

• 04

  A change that shows weeks later

  Muscle thickness decreases as the period without use builds up, so it takes several weeks before you notice a difference in the mirror. Keeping photos from the same angle makes comparison easier.

1. 01

   Identifying the cause

   By clenching and touch, we see whether muscle, salivary glands or bone is creating the line.

2. 02

   Choosing points and product

   We compare muscle thickness on both sides to set the injection points, and choose the product: Korean-made, Coretox or imported.

3. 03

   Comparing weeks later

   Several weeks later, when muscle thickness has reduced, we look at the change with photos taken from the same angle.

What the procedure is like

• You can go about your day as usual on the same day.
• For the first few days, it helps to cut down on very tough food or chewing gum for long periods.
• Don’t massage the injection points firmly.

Safety & considerations

The larger the muscle’s share in the width, the more visible the result of Jaw Botox. If bone or fat is the cause, it may not change as much as you expect, so we check the cause first. Effect and duration vary from person to person.

1. Same day to a few days

   Chewing feels unfamiliar

   The injection points may feel stiff, or you may feel less force when chewing tough food.

2. 2–4 weeks

   Thickness starts to reduce

   As the muscle is used less, you begin to feel the side of the jaw gradually thinning.

3. 2–3 months

   Most noticeable

   This is when the change shows best. (Results vary from person to person.)

4. About 6 months

   Gradual return

   As the muscle is used again, its thickness returns. If you have a clenching habit, it may return sooner.

Sometimes two or more causes are involved, so the examination sorts out how much each contributes.

• Q. What kind of amount is 50u?

  Jaw Botox comes as a single option using 50 units (50u) of botulinum toxin. We look at muscle thickness and left–right differences to decide where and how to divide this amount. If chewing habits have made one side thicker than the other, the amount on each side can differ.

• Q. Will my face get smaller?

  What decreases is the thickness of the muscle at the side of the jaw, so the change appears as a narrower-looking lower face from the front. The width of the cheekbones and bone stays the same. However, if the jaw looks wide because of bone or fat, a muscle injection makes little difference, so before injecting we ask you to clench and feel how much the muscle stands out. The change appears over several weeks and is usually most visible around 2–3 months, though the degree varies from person to person.

• Q. Does it help with a clenching habit?

  Some people feel less stiffness when clenching because the muscle strength is reduced. However, it is not a treatment for teeth grinding or jaw joint symptoms, so if you have pain, we also recommend seeing a dentist. Also, if you have a clenching habit, the muscle is put back to work and its thickness may return more quickly.

• Q. What about eating afterwards?

  Most people can eat their usual meals as before. For the first few weeks, you may feel less force with foods that need a lot of chewing, like tough meat, and this feeling fades over time. For the first few days, it is more comfortable to cut down on very tough foods and long gum chewing.

• Q. Can I have Salivary Gland Botox on the same day?

  If both the muscle and the salivary glands are causes, we sometimes plan them for the same day. The two treatments are injected in different places, so they are marked separately and each amount is decided separately. A part that rises firmly when you clench is treated as muscle, while fullness below the ear or under the jaw that stays soft when you clench is treated as salivary gland, and the examination first sorts out how much each contributes.
