Sunken Cheeks/Undefined Facial Profile

Cheek is a critical facial feature that outlines our facial profile; a round, fuller facial profile delivers a younger-looking face. The collagen in our body peaks at the age of 25 and starts to decline. The loss of collagen will lead to the appearance of drooping skin and loss of tissue volume. Losing volume at the cheeks create sunken cheeks that will give the impression of tiredness and old. However, aesthetic treatment can help slow them down or even reverse them.

Sunken Cheeks

Collagen is a protein and one of its essential functions is to give structural support in tissues. However, we gradually lose collagen as we age, resulting in losing volume in tissue, one of the obvious observations is the development of sunken cheeks.

Scientists recently tend to believe that the manifestation of ageing is not drooping skin but skin losing volume/skin depression. During the ageing process, our skin loses its collagen and subcutaneous fat which causes the loss of tissue volume and structural support in the skin. This change will make the skin uneven and depressed. Some common locations that show depression during ageing are forehead, temple, eye lid and cheek.

From the aesthetic point of view, a face with plump cheeks creates smooth facial contour and a younger-looking appearance. On the other hand, a face with sunken cheeks creates an unsmooth facial contour and makes the person look tired, old, sad, and mean.


Sunken skin is mainly caused by ageing. Ageing stimulates the loss of collagen which will reduce the structural support of tissues, leading to the loss of volume and plumpness of the skin and drooping skin. When sunken skin happens at the cheek, we can see cheek depression and a drooping jawline.

Other possible reasons for sunken cheeks:

  • Wide zygomatic arch or high cheekbone can strength the depression appearance at the cheeks;
  • Lack of fat tissue at the deep cheek layer. Some people were born with little to no fat tissue at their deep cheek layer. This condition creates unwanted shadow at the cheeks that disturb a balanced facial appearance.
  • Injection Failure. Improper or excessive fat injection on the face may cause accumulation of fat on the face and drooping chin due to excessive fat injection at the jawline.
  • People who are smokers or have poor sleep patterns.


●Mild Sunken Cheeks. Mostly happens at the age of 20+. Mild depression or concave at their cheeks are only visible at a certain angle and light.

●Moderate Sunken Cheeks. Happens at the age of 25-35+. Moderate depression at the cheeks. Starts to develop depression at other locations such as temples. Depression features are visible under light.

●Severe Sunken Cheeks. Several areas on the face including cheeks have shown depression. Cheekbones become more prominent.


A. Hyaluronic Acid Dermal Fillers

What is it?

Hyaluronic acid (HA), also known as hyaluronate, is naturally found in tissues and cells. In aesthetic treatment, hyaluronic acid can act as a filler and is injected into the dermis layer to fill up the folds/depressions or plump certain areas such as lips, cheeks, nose and chin. The injected hyaluronic acid will smooth and fill lines and wrinkles, and add volume to the face naturally. As hyaluronic acid can be naturally metabolised and will not remain in the body, there are no side effects of injecting HA. Also, having repeated courses of HA injection is safe and effective for long term results.

How does it work?

To drive volume back to the cheeks, medium molecular weight hyaluronic acid will be injected into the skin at the sunken area at the cheeks. The injected hyaluronic acid will group with the hyaluronic acid that already exists in the body naturally to plump up the hollow cheeks. The resulting round and filled cheeks help to smooth the facial contour, defining and shaping a youthful look.


1. Face-to-face consultation: Confirmation of a detailed plan of injection areas and dosage after fully understanding the client’s conditions and desired results.

2. Pre-treatment preparation: Clean and disinfect the injection areas. Confirm the injection solution has not been opened.

3.Injection: Injecting the solution at the depressed cheeks. Massage the injection areas while injecting to fill the indentation at the cheeks.

4. Post-treatment care.

Duration: 30-45 mins

Who is it for?

  • People with unsmooth facial contour caused by sunken cheeks;
  • People with sunken cheeks due to wide zygomatic arch or high cheekbone;
  • People who have shown early sign of sunken cheeks;
  • People who want a natural, smooth facial contour quickly;

B. Thread lift

What is thread lift:

Thread lift is currently the most effective face lifting technique. By embedding threads to the dermis layer, which lifts the face according to the direction and interval of the threads, it stimulates the skin, and further activates fibroblasts to produce collagen. Thread lift restores skin’s lifting ability, preventing it from sagging. Therefore, embedding threads in a big V shape can instantly lift the face shape and result in a slimmer face.

How does it work:

Thread lift treatment enables embedding threads in the skin to stimulate regeneration of collagen. These new collagens will contract naturally and lift cheek and sagging skin to create a youthful look. Also, embedding threads in a big V shape can lift the drooping skin at the lower part of the face to regain a tightened face. Doctors will develop a unique treatment plan for each client based on their condition and expectation.


1. Face-to-face consultation: Develop a unique treatment plan based on the client’s condition and desired results.

2. Apply anesthetic: Apply anesthetic externally. Clean and disinfect the areas to be embedded with threads.

3. Pre-treatment: Fully understand the treatment plan. Check the quality and quantity of the threads.

4. During treatment: Proceed with the treatment plan to embed threads.

5. Post-treatment precautions.

Duration: 45-60 mins

Who is it for:

  • People who have sunken cheeks along with drooping skin;
  • People who have drooping skin on their face due to signs or early signs of ageing;
  • People who have observed loss of their facial volume and support and significant depression at their cheeks;
  • People who do not receive desired results from filler therapy alone;
  • People who want to quickly create a natural, fuller face contour by stimulating the proliferation of collagen;

MERZ ULTHERAPY®is a non-surgical aesthetic treatment. It enables high-intensity ultrasound to precisely focus to the SMAS layer, stimulate the self-renewal mechanism of skin tissue, and result in a series of rejuvenation effects such as tightening, increased elasticity, lifting, wrinkle reduction, whitening, and pigmentation. Apart from regaining a youthful look, the technology also helps you to reduce fat deposits. For example, one single MERZ ULTHERAPY® treatment not only helps you to restore a younger skin but also helps you to get rid of the double chin and create well-defined face contours.

How does MERZ ULTHERAPY® work:

ULTHERAPY® engages precise ultrasonic energy to go 4.5mm, 3.0mm and/or 1.5mm skin deep, triggering cellular friction to generate high heating energy at pinpointed thermal focal points. The heat generated at these focal points will stimulate tissue self-renewal mechanism, collagen regrowth, and an increase in collagen fibre and elastic fibre. Provide instant reverse of ageing signs.


1. Face-to-face consultation: Suggest treatment plan based on client’s condition and expectation.

2. Anesthetic: Apply Anesthetic externally. Clean and disinfect the treatment areas.

3. Pre-treatment preparation: Draw markings on the face to define treatment areas. Adjust treatment parameters based on the client’s signs of aging on the face.

4. During treatment: Perform the MERZ ULTHERAPY treatment. Focus on the areas of the double chin and the jawline.

5. Post-treatment repair: Medical-grade facial repair mask + QDEL Phototherapy mask to nourish and repair the skin.

6. Post-treatment caring.

Duration: 1.5-2 hr

Who is it for:

  • People who have severe sunken cheeks.
  • People who want to improve their ageing signs by stimulating the proliferation of collagen.
  • People who have experienced disappointing results on improving their sunken cheeks from injection treatments.
  • People who want to receive long term treatment for anti-ageing and improving their sunken cheeks.
  • People who do not rush into immediate results and are looking for long term treatment with sufficient financial support.

Thermage uses radiofrequency technology to heat the dermis. The tissue at the localised dermis area will be damaged and hence its self-healing process will be stimulated. The healing process promotes the formation and remodelling of collagens, which will tighten, smoothen, and lift the skin, resulting in re-contouring and slowing down the ageing process. Similar with Ultherapy, Thermage delivers a significant face slimming effect, helping to firm our skin, lift the facial contour, and create a more defined lower jawline.

How does THERMAGE work:

Thermage is a radiofrequency treatment. The patented applicator will contact your skin and deliver the accurately set radiofrequency to the dermis and heat it up to 65℃ – 75℃. The high temperature will stimulate the self-healing mechanism. A large amount of collagen in the dermis will be regenerated, resulting in an instant firming effect on the face.
