Square Jaw Botox in Seoul: Complete V-Line Guide, Prices & Best Clinics 2025

Square jaw Botox, known as "사각턱 보톡스" in Korean, has become one of Seoul's most popular non-surgical facial contouring treatments. This simple injection procedure can transform a square, masculine jawline into a soft, feminine V-line shape without surgery, making it a favorite among both Korean locals and international beauty tourists.

What is Square Jaw Botox?

Square jaw Botox is a non-surgical treatment that uses botulinum toxin injections to reduce the masseter muscles - the large chewing muscles on the sides of your jaw. When these muscles are overactive or enlarged, they create a wide, square-shaped lower face. By relaxing these muscles with Botox, the jaw gradually slims down, creating the coveted V-line facial contour.

How It Works

1. Muscle Relaxation: Botox temporarily blocks nerve signals to the masseter muscles
2. Muscle Atrophy: Relaxed muscles gradually decrease in size over 4-8 weeks
3. Facial Contouring: As muscles shrink, the jawline becomes more defined and V-shaped
4. Collagen Remodeling: Skin adapts to the new facial structure
