Double Chin Removal in Singapore | What are the Causes & Treatment
A double chin, medically known as submental fullness, develops when excess fat accumulates beneath the chin. This fullness can soften the definition between the chin and neck and create the appearance of a second chin.
However, excess fat is not the only cause of a double chin. Skin laxity, ageing, genetics and facial anatomy can also affect the appearance of the chin and jawline. A double chin is generally not a medical concern, but some people may choose treatment to improve their chin and jawline definition.
What Causes a Double Chin?
Several factors can contribute to a double chin. Identifying the underlying cause helps determine the most suitable double chin treatment.
- Age – As we age, the skin gradually loses collagen and elastin. Reduced skin firmness and increased laxity around the chin and neck can make submental fullness appear more noticeable.
- Weight and Fat Distribution – Weight gain can increase fat beneath the chin, but people at a healthy body weight can also develop a double chin depending on how their body naturally stores fat.
- Genetics – Genetics can influence facial structure, skin elasticity and where the body tends to store fat. Some people are therefore more prone to developing submental fullness regardless of their overall weight.
- Facial and Chin Anatomy – A smaller or recessed chin, jaw structure and the natural anatomy of the neck can make fullness beneath the chin appear more prominent.
Double Chin Removal in Singapore | Non-Surgical Treatment Options
1. High Intensity Focused Ultrasound | HIFU Treatment for Double Chin & Skin Lifting
High-Intensity Focused Ultrasound (HIFU) is a non-invasive treatment that delivers focused ultrasound energy at selected depths beneath the skin. Doctors use HIFU to improve skin laxity, sagging jowls, jawline definition and loose skin beneath the chin without surgery.
Unlike treatments that primarily work at the skin surface, HIFU concentrates ultrasound energy at precise points within deeper tissues. At each treatment point, the energy produces controlled thermal coagulation, which triggers collagen contraction followed by gradual collagen remodelling.
How Do Different HIFU Depths Work?
The face consists of multiple tissue layers, and each layer contributes differently to facial firmness and contour. HIFU systems use different treatment depths to target specific layers beneath the skin.
- 1.5 mm – Superficial Dermis
The shallower depth targets the superficial dermal layer. It can stimulate collagen remodelling and help improve skin firmness and fine textural laxity. - 3.0 mm – Deeper Dermis and Subcutaneous Tissue
This depth delivers ultrasound energy deeper beneath the skin and can help stimulate collagen remodelling in the deeper dermal and superficial subcutaneous tissues. Doctors may use this depth when treating skin laxity around the lower face, jawline and neck. - 4.5 mm – Deeper Supporting Tissue / SMAS Level
The 4.5 mm treatment depth is commonly used to reach deeper fibromuscular supporting tissues, including the Superficial Musculoaponeurotic System (SMAS) in appropriate facial areas. The SMAS contributes to the structural support of the face and is also a tissue layer manipulated during surgical facelift procedures.
By creating controlled thermal coagulation points at this deeper level, HIFU can produce tissue contraction and stimulate a longer-term healing and collagen-remodelling response. This can gradually improve lower-face laxity, sagging jowls and jawline definition.
2. Microfocused Ultrasound with Real-Time Imaging
Microfocused ultrasound with real-time ultrasound imaging (MFU-V) is another non-invasive ultrasound technology used for lifting and tightening the skin.
Unlike ultrasound treatments performed without visualisation, this technology allows the doctor to visualise the tissue layers during treatment and confirm that energy is being delivered at the intended depth.
The treatment delivers precise microfocused ultrasound energy at selected depths to create controlled thermal coagulation points. This stimulates the body's collagen-remodelling response and can gradually improve skin laxity and definition around the jawline, under-chin area and neck.
MFU-V may be considered for patients whose double chin appearance is partly related to loose or ageing skin rather than excess fat alone. Results develop progressively as collagen remodels and may continue to improve over several months.
3. Monopolar Radiofrequency (RF) Skin Tightening
Monopolar radiofrequency (RF) provides another non-invasive option for patients with skin laxity around the lower face, jawline and under-chin area.
The technology delivers controlled radiofrequency energy into the tissue, generating heat within targeted tissue layers while protecting the skin surface.
This controlled heating can cause immediate collagen contraction and stimulate longer-term collagen and elastin remodelling, helping improve skin firmness and overall lower-face contour over time.
Monopolar RF does not work in exactly the same way as HIFU. Ultrasound technologies deliver focused energy at specific tissue depths, while monopolar RF creates controlled volumetric heating within the treated tissues.
Depending on the patient's anatomy and degree of laxity, a doctor may recommend HIFU, microfocused ultrasound with imaging, monopolar RF or a combination approach.
4. Laser Thermolysis | Non-Invasive Laser-Based Fat Reduction
Laser thermolysis is a non-invasive treatment that uses controlled laser energy to target localised fat beneath the chin. The laser energy heats the subcutaneous fat layer to a therapeutic temperature, causing controlled damage to targeted fat cells while the treatment system helps protect the skin surface.
Following treatment, the body gradually clears the affected fat cells through its natural processes. This can help reduce submental fat and improve the contour of the chin and jawline over time.
The controlled heating may also stimulate collagen remodelling, which can provide some improvement in skin firmness. However, the primary purpose of laser thermolysis is fat reduction rather than skin lifting.
5. Chin Fillers Augmentation
This is also another treatment that reduces visible signs of aging caused by volume loss. As we age, another prominent area for skin aging is the chin and jaw area. Saggy skin in the under chin area contributes to the appearance of double chin. This is the result of loose skin hanging from the chin or neck. As fillers contain an ingredient called Hyaluronic Acid, by applying the fillers to the chin or jaw area, they can add volume to the facial tissues. This is done by stimulating collagen production and delivering moisture to the skin, making the face plump.
6. Jawline Sculpting Injection
Botulinum toxin injectables help reduce the muscle bulk located in the jaw area. By relaxing the jaw muscles, it can give the lower part of the face more definition. Apart from the jaw, injecting the neck's surrounding muscles can cause the muscles to tighten which helps to lift the neck and narrow the lower face.
Finding the Right Double Chin Treatment
A double chin does not have a single cause or a one-size-fits-all treatment. Submental fat, skin laxity, chin projection, jaw structure and muscle bulk can each contribute to the appearance of the lower face.
At Ensoul Medical Clinic, our doctors assess these factors before recommending a double chin treatment in Singapore. Depending on your facial anatomy and concerns, treatment may involve HIFU, microfocused ultrasound, monopolar radiofrequency, laser thermolysis, chin augmentation, jawline sculpting injections or a combination of treatments.
The goal is not simply to reduce fullness beneath the chin, but to address the contributing structures and create a more defined, balanced chin and jawline while maintaining natural facial proportions.
