Masseter Muscle Treatment (Face Slimming)

Masseter muscle treatment is a non-surgical facial slimming procedure that reduces the size of the masseter muscles (jaw muscles) to create a softer, slimmer, and more V-shaped facial appearance. It is also commonly used to treat teeth grinding (bruxism) and jaw clenching.

What Is Masseter Muscle / Face Slimming Treatment?

This treatment uses anti-wrinkle injections (Botulinum toxin) placed into the masseter muscles located at the sides of the jaw. By relaxing these muscles, their bulk gradually reduces, resulting in a slimmer lower face and improved facial balance.

⚠️ This treatment reduces muscle size, not fat or bone.

How Masseter Slimming Works

Botulinum toxin is injected into each masseter muscle

  • Muscle activity is reduced

  • Over time, the muscle decreases in size (atrophy)

  • Jawline becomes softer and more contoured
