1. General Information and Description

Jaw Slimming Injection is a prescription treatment designed to contour the lower face by relaxing the masseter muscles, which are the jaw muscles responsible for chewing and for creating a square facial shape when enlarged. By reducing the activity of these muscles, the lower face gradually appears slimmer, softer, and more V-shaped.
This non-surgical procedure is a popular option for individuals looking to achieve a refined jawline without downtime or invasive techniques.

2. How It Works

The injection temporarily blocks nerve signals that cause the masseter muscles to contract.
With reduced movement, the muscle becomes less active and gradually decreases in size over several weeks through a natural process known as muscle atrophy.
As the muscle volume reduces, the facial contour appears slimmer and more tapered.

3. What to Expect & When Results Appear

The procedure takes only a few minutes with minimal discomfort. Mild swelling or small injection marks may occur but usually settle quickly.
Subtle changes typically begin to appear within 2 to 3 weeks, with full slimming results visible around 6 weeks.
Effects generally last 3 to 4 months, and regular maintenance sessions help maintain a consistent, contoured jawline.

4. Who Is a Good Candidate

Jaw Slimming Injection is suitable for individuals who:

• Have enlarged or overactive masseter muscles

• Want a slimmer, more V-shaped or tapered jawline

• Prefer a non-surgical treatment with minimal downtime

• Experience jaw tension or teeth grinding, also known as bruxism, and want functional relief alongside aesthetic benefits

It may not be ideal for individuals with naturally small masseter muscles or those seeking a structural bone contour change.
