What Are Double Chin Injections?

Double Chin Injections are non-surgical treatments used to reduce fullness under the chin and improve the transition between the chin, jawline, and neck. A double chin can occur due to localized fat, genetics, aging, posture, skin laxity, or facial structure, even in patients who are not overweight.

Unlike surgery or liposuction, double chin injections do not require incisions, general anesthesia, or long recovery time. They are designed to gradually improve the under-chin contour and create a slimmer, more defined lower-face appearance.

At Seomyeon One Clinic, every double chin treatment plan is customized according to the amount of submental fat, jawline definition, chin projection, skin elasticity, and desired result.

How Do Double Chin Injections Work?

Double chin injections usually work by targeting localized fat beneath the chin. Fat-dissolving ingredients are injected into the submental area, where they gradually help break down small fat deposits. Over time, the treated area may become slimmer and more defined.

If the double chin is caused by weak chin projection, loose skin, or poor jawline structure, fat-dissolving injections alone may not be enough. In those cases, the doctor may recommend combining treatment with chin filler, jawline contouring injections, Skin Botox, HIFU, radiofrequency tightening, or collagen-stimulating injectables.

Who Is a Good Candidate?

Double Chin Injections may be suitable for patients with mild to moderate fullness under the chin.

You may be a good candidate if you:

• Have a visible double chin
• Have localized fat under the chin
• Want a sharper jawline
• Want a slimmer side profile
• Prefer non-surgical treatment
• Want minimal downtime
• Are not ready for liposuction
• Have good or moderate skin elasticity
• Want gradual, natural-looking improvement
• Want a personalized facial contouring plan

A consultation is important because double chin appearance can be caused by fat, skin laxity, weak chin structure, neck posture, or aging changes.

What Causes a Double Chin?

A double chin can develop for several reasons.

Common causes include:

• Localized submental fat
• Genetics
• Aging-related skin laxity
• Weak chin projection
• Poor jawline definition
• Weight fluctuation
• Posture habits
• Reduced skin elasticity
• Natural facial structure

Because causes vary, the most effective treatment plan depends on a proper facial and neck assessment.

Fat-Dissolving Injections for Double Chin

Fat-dissolving injections are commonly used when the double chin is caused by localized fat.

The treatment is performed by injecting selected ingredients into the under-chin area to help reduce small fat pockets gradually. Multiple sessions may be needed depending on fat thickness, treatment response, and desired contour.

As the under-chin area becomes slimmer, the jawline may look cleaner and the face may appear more defined from the front and side.

Double Chin Injections vs Chin Filler

Double chin injections and chin filler treat different concerns.

Double chin injections reduce fullness under the chin. Chin filler improves chin projection and facial balance. If the chin is recessed or short, adding subtle chin projection may make the jawline and neck angle appear more defined.

In some patients, combining double chin injections with chin filler can create a more balanced and sharper lower-face profile.

Double Chin Injections vs Liposuction

Double chin injections are non-surgical, gradual, and suitable for patients with mild to moderate fat under the chin.

Liposuction removes fat more directly and may be more suitable for patients with larger fat deposits or those who want more dramatic results. However, surgery involves more downtime, swelling, and recovery.

Double chin injections are often preferred by patients who want a less invasive option and are comfortable with gradual improvement.

What Happens During the Procedure?

Treatment begins with a consultation and lower-face assessment.

The doctor evaluates under-chin fat, jawline definition, chin projection, skin elasticity, and neck contour. After marking the treatment area, the selected injection formula is placed into the under-chin area using fine needles.

Most treatments are completed within approximately 20 to 30 minutes. Patients can usually return to normal daily activities shortly after the procedure.

Results and Recovery

Results develop gradually because the body needs time to process the treated fat.

Some patients notice improvement after a few weeks, while more visible contour change may require multiple sessions. The number of sessions depends on the amount of submental fat and the patient’s desired result.

Temporary swelling, tenderness, redness, bruising, or mild firmness may occur after treatment. Swelling is common with double chin injections and usually improves over time.

Can Double Chin Injections Be Combined with Other Treatments?

Yes. Combination treatment is often recommended for better lower-face contour.

Popular combination treatments include:

• Chin Filler
• Jawline Contouring Injections
• Masseter Botox
• Skin Botox
• Fat-Dissolving Injections
• HIFU Lifting
• Radiofrequency Skin Tightening
• Collagen Stimulators
• Skin Boosters
• Medical Facials

Your doctor will recommend the most suitable combination depending on your double chin cause, skin elasticity, and jawline goals.
