Sharpen your jawline with platysma Botox
A dual-specialty doctor with a background in plastic surgery, bridging cosmetic surgery and ophthalmology. At the university hospital, he performed numerous high-difficulty cases, primarily focusing on eye and facial bone surgeries, cultivating precise techniques grounded in anatomy. He prioritizes achieving both aesthetic beauty and functional safety, offering customized treatments around the eyes that incorporate ophthalmological expertise. He actively utilizes not only incisional surgery but also non-invasive procedures like hyaluronic acid injections.

Hello, I'm Ryutaro Natsume, an image designer and cosmetic surgeon.

For sharp contouring and preventing sagging, we recommend Botox for the platysma muscle.
Also known as Nefertiti Botox.
Nefertiti was an ancient Egyptian queen renowned for her slender neck and beautiful facial contours. The name signifies the potential to achieve such exquisite facial contours and neckline.
The platysma muscle has the ability to pull the skin near the jawline downward.
Facial muscles consist of elevators and depressors, and the platysma is classified as a depressor.
The depressor muscles literally exert a strong downward pulling force, which causes sagging.
It is important to appropriately weaken it with Botox.
Strong movement of the sternocleidomastoid muscle can cause vertical lines to appear on the neck, known as platysma bands. These platysma bands can also make the neck appear aged.
The muscle that pairs well with botulinum toxin injections for the sternocleidomastoid muscle is the depressor anguli oris. The depressor anguli oris is the muscle located beneath the corners of the mouth, responsible for pulling the mouth into a downward-turned expression.
Individuals with strong sternocleidomastoid muscle activity often also exhibit strong depressor anguli oris muscle activity, so Botox injections are frequently administered to both muscles simultaneously.
For individuals over 50 with significant skin laxity in the neck, Botox injections into the platysma muscle may worsen sagging.
In such cases, we may apply Botox mildly to the platysma band only or treat skin laxity with Morpheus8.
