Sunken Cheeks: Causes, 4 Treatment Options, and Prevention

Last Modified: April 17, 2026

Have you noticed your cheeks looking less full over time? Sunken cheeks, often caused by a natural loss of volume, can affect both men and women and may lead to a hollow or less defined facial appearance. 

In this article, we’ll explore the underlying causes of sunken cheeks, including how ageing and lifestyle choices can influence facial volume. We’ll also look at treatment options that may help address volume loss in the cheeks, along with preventive measures that support healthy skin and facial structure.

What Are Sunken Cheeks?

Flat or sunken cheeks occur when the cheeks lose their natural volume, creating a hollowed appearance that may alter facial proportions. This volume loss can result from several factors that reduce subcutaneous fat and collagen, leading to a slimmer or more angular facial structure.

Causes of Sunken Cheeks

Sunken cheeks can arise from various factors, leading to a hollow appearance in the face. Common contributors include the natural ageing process, genetics, weight loss, and certain illnesses.

Natural Ageing Process

As we age, several changes occur in the skin and underlying tissues that may contribute to the development of sunken cheeks:

  • Loss of Fat Pads: Subcutaneous fat gradually diminishes, particularly around the cheeks and jawline, which can make the cheeks look less full..
  • Reduced Collagen Production: Collagen, which provides structure and elasticity to the skin, decreases over time, resulting in reduced volume and firmness.
  • Skin Thinning: The skin becomes thinner and less elastic, making the underlying bone structure more visible.

Genetic Factors

Genetics play a role in shaping facial structure. Some individuals may naturally have less defined cheek contours due to their inherited bone structure. This predisposition can give the cheeks a slimmer appearance, regardless of age or weight.

Weight Loss

Significant weight loss may reduce facial fat, which can make the cheeks look less full. As overall body fat decreases, the face often reflects this change, sometimes giving it a slimmer or more angular appearance.

Illness

Certain medical conditions can contribute to changes in cheek volume:

  • Lipoatrophy: Often associated with conditions like HIV, lipoatrophy results in localised fat loss in the face.
  • Eating Disorders: Conditions such as bulimia and anorexia can cause significant weight loss and malnutrition, which may affect facial fullness.
  • Chronic Illnesses: Diseases such as cancer and tuberculosis can also result in malnutrition and changes in cheek appearance.

Treatment Options for Sunken Cheeks

There are different treatment options that may be used to address cheek volume loss. These range from non-invasive procedures to surgical approaches, each with different considerations.

Dermal Fillers

Dermal fillers are commonly used to address cheek volume loss and support mid-face structure. They work by attracting water molecules, which may improve skin hydration. This non-surgical procedure involves injecting filler into specific areas of the cheeks using a cannula or fine needles. A topical anaesthetic may be applied beforehand to minimise discomfort.

The effects typically last between 6 months and 2 years, depending on factors such as individual metabolism, lifestyle, and the type of filler used.

Fat Transfer (Fat Grafting)

Fat transfer, also known as facial fat grafting, is a procedure that involves harvesting fat from one area of the body and injecting it into the cheeks to address volume loss.

The process typically consists of three stages. First, fat is collected from areas such as the abdomen, thighs, or hips through liposuction, using small incisions to extract fat cells. The fat is then purified to remove impurities, blood, and other fluids. Finally, the purified fat is injected into the cheeks using fine needles or cannulas.

Because the patient’s own fat is used, this approach reduces the likelihood of rejection or allergic reactions. However, potential risks remain, including infection at the donor and injection sites or fat necrosis, where some of the injected fat may not survive, which can lead to lumps or unevenness.

Recovery usually involves an initial healing period, during which bruising and swelling may last for about one to two weeks. Patients are usually advised to avoid strenuous activities for several days to support healing.

Some changes may be visible soon after the procedure, though it can take several months for the fat to fully integrate and settle.

Cheek Implants (Malar Augmentation)

Cheek implants are a surgical option that may be used to address changes in cheek volume. The procedure usually takes about 30 to 45 minutes and can be performed under local anaesthesia with sedation or general anaesthesia.

To place the implant, the surgeon makes an incision either inside the mouth or through the lower eyelid to create a pocket for the implant. Once positioned, the implant is secured and the incision is closed with dissolvable stitches.

Recovery typically involves managing swelling and discomfort. Initial swelling often reduces within a few weeks, though it may take several months for the cheeks to settle into their final appearance. Potential complications include infection, asymmetry, implant displacement, scarring, and, in rare cases, nerve damage.

Non-Surgical Options (Thread Lifts, Skin Tightening)

Non-invasive treatments such as thread lifts and radiofrequency skin tightening may be used to address mild changes in cheek volume and skin support without surgery.

Radiofrequency Skin Tightening

Radiofrequency skin tightening uses energy to heat the deeper layers of skin, which may support collagen production and improve elasticity. Treatments are usually performed as a series of sessions, each lasting about 30 to 60 minutes. Patients may experience temporary swelling or redness, and many are able to resume normal activities soon after treatment.

How to Prevent Sunken Cheeks

While it may not be possible to completely prevent changes in cheek volume, certain practices can support overall health and skin integrity.

Oral Health and Bone Density

Maintaining good oral health may help reduce the risk of bone loss in the jaw, which supports overall facial structure. Regular dental appointments can identify and address issues early, supporting healthy jaw function over time.

Sun Protection and Skincare

Sun protection and good skincare practices may help slow down changes that contribute to sunken cheeks. Prolonged exposure to UV radiation can accelerate collagen breakdown, which leads to reduced skin elasticity. Using sunscreen daily and skincare products that support skin health may help maintain skin elasticity and reduce visible signs of volume loss.

Diet and Lifestyle Choices

A diet rich in antioxidants may support skin elasticity and overall facial health. Foods high in antioxidants include:

  • Fruits and Vegetables: Leafy greens (like spinach and kale), colourful fruits (such as berries, tomatoes, and citrus), and other vegetables are good sources of vitamins A, C, and E.
  • Nuts and Seeds: Provide healthy fats and vitamin E, which support skin health.
  • Legumes: Beans and lentils are high in phenolic compounds that contribute to overall health.

Drinking enough water throughout the day is equally important, as it keeps the skin hydrated from within.

Complications and Long-term Effects

Over time, changes in cheek volume may contribute to differences in facial appearance and structure. Some of these changes may include:

  • Appearance of Ageing: Reduced cheek volume may be associated with wrinkles and sagging skin.
  • Changes in Facial Proportions: A decrease in cheek fullness can alter the relative appearance of other features, such as the nose or chin.
  • Sagging Skin: Reduced fat in the cheeks may affect elasticity, leading to drooping or deeper lines around the nose and mouth.
  • Impact on Self-perception: These visible changes may influence how some individuals view themselves.

When to Seek Professional Help

Some individuals may choose to consult a qualified professional if they notice certain changes in their cheeks over time. These may include:

  • Visible Volume Changes: Noticeable hollowness in the cheeks that changes facial appearance.
  • Differences in Contour: Adjustments in cheek contour that affect how facial features relate to one another.
  • Wrinkles or Sagging: The development of deeper lines or sagging skin around the cheeks and mouth.
  • Increased Self-awareness: Becoming more aware or concerned about facial changes.

When you are experiencing any of these indicators, book a consultation now.

Conclusion

Understanding the causes and possible treatment options for sunken cheeks can help individuals make informed decisions about their care. Cheek volume changes may arise from factors such as age-related volume loss, dietary habits, and skincare practices.

Both surgical procedures, such as cheek implants, and non-surgical approaches, including thread lifts and radiofrequency skin tightening, may be considered to address changes in facial volume and skin support. Preventive measures focusing on oral health, sun protection, and a diet rich in antioxidants may also support overall skin and facial health.

By taking steps to understand these factors, individuals can feel more informed about how facial changes occur over time. Speaking with a qualified professional can provide further guidance on suitable options tailored to individual needs..
