A premium botulinum toxin treatment: muscles and salivary glands are precisely identified under ultrasound guidance, and the injection is placed accurately while directly visualized. The right spot, and only as much as needed.
We promise this to everyone who visits us.
From entering the treatment room to the end of your care, an independent path with no moving around — relax in a space that is yours alone.
No self-cleansing. A skilled aesthetician carefully handles everything from cleansing to aftercare.
If you request a consultation with the director, the director will see you personally — without exception.
Advanced PRESS device, machine-assisted anesthetic cream absorption, microneedles, analgesic injections, nerve anesthesia
All injectables, tips, and shot counts are opened in front of you and photographed for record-keeping.
We assess skin thickness, fat layer, and muscle layer by ultrasound before treatment.

We identify the cause by ultrasound and reduce unnecessary treatment.
If your contour isn't smooth, fat may not be the only reason.
The right spot, just the right amount — the fastest, most graceful change.
Mason Clinic precisely distinguishes fat, muscle, and salivary glands by ultrasound to identify the true cause first.
Premium botulinum toxin injected accurately while viewing the muscle.
With precise ultrasound diagnosis, we complete natural, accurate line improvement without relaxing unnecessary muscles.
