Masseter Botox in Korea: What You Need to Know

What Is Masseter Botox?

Masseter Botox is a non-surgical injectable treatment that targets the masseter muscles, which are responsible for chewing and jaw movement. When these muscles become enlarged due to genetics, teeth grinding, or chronic jaw clenching, they can create a wide or square-looking lower face. By relaxing the masseter muscles, Botox helps slim the jawline and soften facial contours.

What Does Masseter Botox Do?

Masseter Botox reduces muscle activity and volume over time. Key benefits include:

  • Slimming a wide or bulky jawline
  • Creating a softer, more V-shaped facial contour
  • Reducing jaw tension and facial discomfort
  • Helping relieve teeth grinding (bruxism)
  • Improving facial symmetry

Results appear gradually and remain natural-looking.

Why Is Masseter Botox Popular in Korea?

In Korea, masseter Botox is extremely popular because it:

  • Offers facial slimming without surgery
  • Aligns with the K-beauty preference for a V-line face shape
  • Provides both aesthetic and functional benefits
  • Requires minimal downtime
  • Can be combined with other contouring treatments

It is one of the most commonly performed Botox procedures in Korea.
