Frequently Asked Questions

How does Trapezius Slimming Injections work?

Trapezius Slimming Injections work by targeting the overactive trapezoid muscle, relaxing the muscle to inhibit it from overactivity, and allowing the bulky muscle that’s accumulated to wear down and shrink.

The result is a visible slimming of the treated area. In the case of trapezius, the outcome is a slimmer, elegant appearance for the neck and shoulders with improved definition of the shoulder-to-neck angle. It can also enhance the appearance of good posture.

In addition to the cosmetic purpose of providing a more feminine appearance to the neck, shoulder, and back area, people experiencing neck & shoulder pain due to overdeveloped trap muscles can also benefit from these trap muscle injections. Trapezius injections can also provide functional relief for certain types of tension headaches.
