Masseter Botox in Korea: Complete Guide to V-Line Face Slimming (2025)
The coveted V-line face shape has become a defining feature of Korean beauty standards, and masseter Botox (사각턱 보톡스) is one of the most popular non-surgical treatments to achieve it. This comprehensive guide covers everything you need to know about getting jaw-slimming Botox in Korea.
What is Masseter Botox?
Masseter Botox involves injecting botulinum toxin into the masseter muscles—the large jaw muscles responsible for chewing. When these muscles are overdeveloped, they can create a square, angular jaw appearance. By relaxing these muscles with Botox, the jaw gradually slims down, creating a more oval or V-shaped face.
How It Works
The masseter muscle (저작근) can become enlarged from:
- Habitual teeth grinding (bruxism)
- Jaw clenching during stress
- Excessive gum chewing
- Genetic factors
Botox weakens these muscles, causing them to shrink over time through disuse atrophy. This creates a slimmer, more feminine jawline without surgery.

- Injection (10-15 min): Multiple small injections into each side
- Aftercare instructions: Provided before you leave
Post-Treatment Care
First 24 hours:
- Avoid lying down for 4 hours
- Don't massage the injection sites
- Skip intense exercise
First week:
- Avoid alcohol and blood thinners
- Don't chew gum excessively
- Sleep on your back if possible
Who is a Good Candidate?
Ideal candidates:
- Square or wide jaw due to muscle (not bone)
- Those who clench or grind teeth
- Wanting subtle, non-surgical facial slimming
- Ages 20-60
Not recommended for:
- Square jaw caused by bone structure
- Pregnant or breastfeeding women
- Those with neuromuscular disorders
Potential Side Effects
Common side effects (usually temporary):
- Mild pain at injection sites
- Minor swelling or bruising
- Temporary jaw weakness when chewing
Less common:
- Asymmetry (correctable with touch-ups)
- Hollow cheeks if over-injected
- Smile changes (rare, temporary)
Important: Choose experienced practitioners to minimize risks. According to Korean dermatologists, injecting too high on the masseter can cause unwanted cheek hollowing.
How Often to Repeat
| Session | Recommended Timing |
|---|---|
| 1st | Initial treatment |
| 2nd | 4-6 months later |
| 3rd | 6-8 months later |
| Maintenance | Every 6-12 months |
With repeated treatments, many patients find they need less frequent sessions as the muscle naturally reduces in size.
