The Jawline Is Not Defined by Fat Alone2026.04.11
— Refining the Face and Neck with Platysma Botox —
Many patients experience:
- A blurred jawline even after facial liposuction
- A short-looking neck
- Lack of definition in profile
In such cases, the cause is not always fat.
Muscle dynamics often play a critical role.
The Platysma: A Downward Pulling Muscle
The platysma is a thin muscle extending from the neck to the lower face.
Its primary function is to pull the facial skin downward.
When overactive, it can lead to:
- A less defined jawline
- Downturned mouth corners
- A shorter neck appearance

What Is Platysma Botox (Botox Lift)?
By relaxing the platysma with Botox,
we can achieve a subtle lifting effect:
- Sharper jawline
- Elongated neck
- More refined profile
Precision Matters
This treatment is highly technique-dependent.
Particularly:
- Over-injection near the midline (around the mouth corners)
may lead to asymmetry or unnatural expressions.
Therefore,
precise anatomical understanding and controlled injection are essential.
Synergy with Facial Liposuction
Optimal results require addressing both:
- Fat volume → Facial liposuction
- Downward muscle pull → Platysma Botox
At AVAN TOKYO, combining these approaches allows for
a more complete and refined jawline outcome.
