Korean Jaw Botox: How Much Does Masseter Reduction Cost in Busan?

What jaw Botox does
The masseter is the main chewing muscle on each side of the jaw. In some people it is naturally large, or it grows bulkier from habits such as clenching or grinding. A prominent masseter can make the lower face look wide or square. Jaw Botox (also called masseter Botox) places botulinum toxin into this muscle to temporarily reduce its activity. Over time, the muscle may become smaller, which can soften the lower face outline.
It is one of the most requested toxin treatments in Korea and a core part of the "V-line" approach to facial contouring. You can read more on our jaw Botox page.

What affects masseter Botox prices in general
If you compare prices in Korea, you will see variation. The main reasons are:
- Toxin brand. Korean-made toxins are generally more affordable than some imported brands. If you prefer a specific imported brand, ask at consultation which options are available.
- Units. Quotes may describe different doses. Compare the number of units, not just the headline price.
- First-visit or event pricing. Introductory prices may apply only once.
- VAT. Some clinics include VAT in their displayed prices; others add it at payment.
- Doctor assessment. A physician-led consultation ensures the dose and placement suit your muscle.
Is jaw Botox right for you?
Jaw Botox works on muscle, so it is most relevant when muscle bulk is part of the cause of a wide lower face. The doctor may ask you to clench your teeth to feel the muscle. Other causes may need a different approach:
- Soft fullness under the jaw. May be discussed with treatments such as a fat-dissolving injection or ONDA.
- Skin laxity or jowls. May be discussed with lifting devices.
- Bone structure or a short chin. Not changed by Botox; chin filler or other options may be considered.
Related listed treatments include the ZERO steroid-free fat-dissolving injection 3cc at 15,000 KRW and ONDA 20,000J at 89,000 KRW (both VAT excluded, first-visit prices). Our V-line contouring page explains how these can fit together.
Timeline: when you might notice a change
Jaw slimming is not immediate. Typical stages are:
- First days. Little visible change; the toxin starts to take effect.
- About one to two weeks. Chewing may feel slightly weaker, especially with tough foods.
- Several weeks. As the muscle reduces in size, the lower face may look gradually softer.
- Later months. Muscle activity slowly returns, and many people choose to repeat treatment to maintain the effect.
Results vary between individuals and are not guaranteed. The degree of change depends on muscle size, facial structure and how your body responds.
Side effects and aftercare
Jaw Botox is generally well tolerated, but common temporary effects include small bumps, redness or bruising at injection points, and mild tenderness. Some people notice chewing fatigue. Less commonly, toxin can affect nearby muscles, which may cause temporary smile asymmetry. Some people also notice a change in cheek contour over time.
It is also worth knowing that a slimmer jaw is not always the most flattering choice for every face. In some people, reducing the masseter too much can make the cheeks look less supported or emphasise sagging. A careful doctor will consider your whole facial balance, not just the width of the jaw, and may suggest a conservative approach first.
Common aftercare advice includes not massaging the area on the day, staying upright for a few hours, and avoiding saunas and intense exercise for the rest of the day. If you are pregnant, breastfeeding or have a neuromuscular condition, consult a doctor first.
Frequently asked questions
Is 50 units enough?
The listed jaw Botox item is 50 units. Whether that suits your muscle is decided by the doctor at consultation.
Will jaw Botox help with teeth grinding?
Some people report less clenching after masseter treatment, but this is not guaranteed. If grinding is a medical concern, it is worth also seeing a dentist.
How often is jaw Botox repeated?
It varies. Many people repeat treatment after several months, but your doctor can advise on timing.
Can I do it on a short trip?
Yes. The appointment is short and downtime is minimal, though the slimming effect develops after you leave.
