Sreborn Skin Clinic Hongdae

Looking for masseter Botox in Seoul? Sreborn Skin Clinic Hongdae provides personalized botulinum toxin treatment for enlarged jaw muscles, a square lower face, jaw clenching, and mild masseter asymmetry.

The product, dose, and injection points should be customized according to muscle thickness, facial width, jaw function, skin laxity, and previous treatment history. Masseter Botox can reduce muscle-related width but cannot narrow the jawbone or remove facial fat.

What Is Masseter Botox?

Masseter Botox involves injecting botulinum toxin into the masseter muscles located at the sides of the jaw.

The treatment temporarily reduces muscle activity. Over time, the muscles may decrease in size, creating a slimmer lower-face contour in patients whose facial width is caused mainly by muscle.

What Can Masseter Botox Improve?

Treatment may be considered for:

• Enlarged masseter muscles
• A muscular square jaw
• Lower-face asymmetry
• Frequent jaw clenching
• Muscle-related facial tension
• Selected teeth-grinding concerns
• Excessive masseter prominence
• A desire for a softer V-line contour

It does not correct every cause of a wide or heavy lower face.

Professional Jaw Assessment

Before treatment, the clinic may evaluate:

• Masseter muscle thickness
• Facial width
• Jawbone structure
• Facial fat distribution
• Jowls and skin laxity
• Left-to-right asymmetry
• Bite and chewing function
• Jaw-joint symptoms
• Teeth-grinding history
• Previous toxin treatment
• Desired degree of slimming

This helps determine whether the concern is caused by muscle, bone, fat, loose skin, or a combination.

Masseter Botox for Jaw Slimming

Patients with large jaw muscles may notice gradual lower-face slimming after treatment.

The result depends on:

• Muscle size
• Facial bone structure
• Dose
• Injection technique
• Individual response
• Chewing habits

Patients with a wide jawbone will continue to have a naturally broad lower face.

Masseter Botox for a V-Line Face

Reducing bulky masseter muscles may create a softer and more tapered jawline.

Some patients may require additional treatment for:

• Under-chin fat
• Jowls
• Loose skin
• Chin projection
• Jawline definition

Masseter Botox alone does not lift sagging tissue or create a more projected chin.

Masseter Botox for Jaw Clenching

Botulinum toxin may reduce excessive masseter activity related to jaw clenching or teeth grinding.

However, jaw discomfort can also result from:

• Temporomandibular joint disorders
• Dental problems
• Bite misalignment
• Stress
• Joint inflammation
• Other facial muscles

Patients with significant pain, locking, or difficulty opening the mouth may require dental or TMJ evaluation.

Masseter Botox for Facial Asymmetry

One masseter muscle may be larger or stronger than the other.

Customized dosing may improve mild muscular asymmetry. Perfect symmetry cannot be guaranteed because bone structure, chewing habits, and facial volume also contribute to facial shape.

Masseter Botox vs. Jawline Filler

These treatments have different purposes.

• Masseter Botox reduces muscle-related lower-face width.
• Jawline filler adds structure and definition.
• Chin filler improves projection and facial balance.
• Combination treatment may create a more defined V-line in selected patients.

Adding filler does not make a wide jaw physically narrower.

Masseter Botox vs. Facial Fat Reduction

Masseter Botox does not reduce fat.

If lower-face width is caused by fat, treatment may involve:

• InMode
• Onda
• HIFU contouring
• Fat-dissolving injections
• Liposuction

A professional assessment helps identify the dominant tissue.

When Will I See Results?

Jaw tension may begin to decrease within several days.

Visible facial slimming develops more gradually as muscle volume reduces, often becoming clearer over several weeks. The timeline varies according to muscle size, dose, and individual response.

How Long Does Masseter Botox Last?

Results are temporary.

Duration depends on:

• Product used
• Dose
• Muscle strength
• Chewing habits
• Individual metabolism
• Previous treatment history

Muscle activity and volume gradually return as the effect wears off.

Possible Side Effects

Temporary reactions may include:

• Redness
• Swelling
• Bruising
• Tenderness
• Jaw fatigue
• Mild chewing weakness
• Temporary asymmetry

Other possible complications include:

• Uneven smile
• Cheek hollowing
• Excessive jaw weakness
• Difficulty chewing hard food
• Increased jowl visibility
• Compensatory muscle bulging
• Changes in facial expression
• Allergic or systemic reactions

Can Masseter Botox Cause Sagging?

Reducing large masseter muscles decreases support and volume in the lower face.

Patients with thin skin, existing jowls, or reduced elasticity may notice more visible laxity after aggressive treatment. Conservative dosing or combination skin tightening may be recommended.

Who May Not Be Suitable?

Treatment may be unsuitable or require additional assessment for patients with:

• Neuromuscular disorders
• Significant chewing weakness
• Severe TMJ dysfunction
• Facial nerve problems
• Active infection
• Pregnancy or breastfeeding
• Certain antibiotic or muscle-relaxant use
• Recent botulinum toxin treatment
• Known allergy to treatment ingredients
• Significant lower-face sagging

All medical conditions, medications, and previous toxin treatments should be disclosed.

Masseter Botox Aftercare

After treatment:

• Avoid rubbing or massaging the jaw.
• Avoid strenuous exercise temporarily.
• Avoid saunas and excessive heat.
• Avoid alcohol if advised.
• Remain upright for the period recommended.
• Do not schedule facial massage immediately.
• Follow the clinic’s instructions.

Contact the clinic for significant smile asymmetry, severe chewing weakness, swallowing difficulty, or other concerning symptoms.

Treatment for International Patients

International patients should provide:

• Previous toxin brand
• Dose and treatment date, if known
• Teeth-grinding or TMJ history
• Previous side effects
• Current medications
• Arrival and departure dates

Schedule treatment early enough for the initial response to be reviewed before leaving Korea.

Will it affect chewing?

Temporary jaw fatigue or reduced strength when chewing hard foods may occur.
