Why Is My Jawline Still Not Sharp After Facial Liposuction? Understanding Platysma Botox (The Botox Lift)2026.07.26
One of the most common questions we hear is:
“I had facial liposuction, but my jawline still doesn’t look as defined as I expected.”
Facial liposuction effectively removes excess fat, but fat is only one factor that determines the appearance of your jawline.
The underlying muscles also play an important role.
One of the most influential muscles is the platysma, a thin muscle that extends from the neck to the lower face.
At AVAN TOKYO, we sometimes combine platysma Botox (also known as the Botox Lift) with facial liposuction or arm liposuction to create a smoother, more elegant upper-body contour.

What Is the Platysma?
The platysma is a broad, thin muscle that runs from the upper chest and neck to the jawline and lower face.
Its primary function is to pull the lower face and neck downward.
As this muscle becomes more active over time, it can contribute to:
- A less defined jawline
- Downturned corners of the mouth
- Vertical neck bands
- A heavier appearance of the lower face

How Does Platysma Botox Work?
Botox relaxes the overactive platysma muscle.
By reducing its downward pull, patients may notice:
- A sharper jawline
- A subtle lifting effect
- A longer, more elegant-looking neck
- A smoother transition from the chin to the neck
Although Botox does not physically lift the skin, reducing the downward tension can improve facial balance and contour in appropriately selected patients.
Why Is It an Excellent Combination with Facial Liposuction?
Facial liposuction removes excess fat from areas such as the cheeks and under the chin.
However, if the platysma continues to pull the lower face downward, some patients may still feel that their jawline lacks definition.
For these patients, combining facial liposuction with platysma Botox may further enhance the contour of the lower face and neck.
Not every patient requires this combination. The decision depends on the balance between fat volume, muscle activity, skin quality, and facial anatomy.

Injection Technique Matters
Platysma Botox is not simply a matter of injecting more units.
The injection sites are critical.
Particular caution is required around the central lower face, especially near the corners of the mouth.
If Botox spreads excessively into nearby muscles, it may temporarily cause:
- Asymmetry of the smile
- Uneven movement of the mouth corners
- Difficulty with certain facial expressions
For this reason, a detailed understanding of facial anatomy is essential.
At AVAN TOKYO, we carefully evaluate each patient’s muscle pattern and inject only where treatment is appropriate to maximize results while minimizing unwanted effects.
A Beautiful Neck Begins with a Beautiful Upper-Body Contour
A refined profile is created by more than just the jawline.
We evaluate the harmony of the entire upper body, including:
- Jawline
- Chin
- Neck
- Shoulders
- Collarbones
- Upper arms
When indicated, combining treatments such as:
- Facial liposuction
- Platysma Botox
- Trapezius Botox
- Levator scapulae Botox
- Arm liposuction
can create a smoother and more elegant transition from the face to the shoulders and arms.
The AVAN TOKYO Philosophy
At AVAN TOKYO, we believe beautiful results come from treating the entire silhouette—not just one isolated area.
Before recommending treatment, we carefully assess:
- Facial and body anatomy
- Muscle balance
- Fat distribution
- Skin quality
- Body posture
- Overall aesthetic proportions
Rather than simply making the face smaller or the arms thinner, our goal is to create natural harmony from the jawline to the neck, shoulders, and upper arms.
Frequently Asked Questions
Is facial liposuction alone enough to improve the jawline?
For many patients, yes. However, if muscle tension from the platysma contributes significantly to the appearance of the jawline, combining facial liposuction with platysma Botox may provide additional refinement.
Can Platysma Botox replace a facelift?
No. Platysma Botox provides a subtle lifting effect by relaxing the downward pull of the muscle. Patients with significant skin laxity may benefit more from procedures such as thread lifting or surgical facelift.
Can Platysma Botox be combined with arm liposuction?
Yes. By improving the jawline, neck, shoulders, and upper arms together, we can create a more balanced and elegant upper-body silhouette.
Risks and Potential Side Effects
Botox injections may cause temporary bruising, swelling, discomfort, asymmetry, temporary muscle weakness, altered facial expression, uneven smile, or insufficient or excessive treatment effect.
Facial liposuction carries potential risks including swelling, bruising, contour irregularities, fibrosis, numbness, hematoma, infection, pigmentation changes, scarring, and asymmetry.
Surgeon’s Message
Creating a beautiful jawline is about much more than simply removing fat.
The best results come from understanding the relationship between bone structure, muscles, fat, and skin.
At AVAN TOKYO, we combine anatomy-based facial liposuction with advanced Botox techniques to create natural, refined contours that extend seamlessly from the jawline to the neck, shoulders, and upper arms.
Our goal is not simply to make one area smaller—but to create a balanced, elegant silhouette that looks beautiful from every angle.
