Quick Answer: Hollow cheeks are a loss of midface volume creating a sunken appearance beneath the cheekbones, caused by ageing, weight loss, genetics, or lifestyle factors. They can be restored with dermal fillers, collagen biostimulators, or fat transfer. If you’re looking to create hollow cheeks: buccal fat removal is permanent, and the sculpted look many people want at 25 frequently reads as gaunt by 45.
Two Different Questions
People search “hollow cheeks” for opposite reasons, and it’s worth naming that upfront.
Some want to fix them. Their face has lost volume through ageing or weight loss, and they look tired or older than they feel.
Some want to create them. The sculpted, high-cheekbone look has been heavily promoted, and buccal fat removal has become a widely discussed procedure.
This article covers both — including the honest warning that links them: the people seeking treatment for hollow cheeks in their 40s and 50s are often dealing with exactly the appearance others are paying to create.
What Are Hollow Cheeks?
Hollow cheeks describe a loss of volume in the midface, creating a sunken or shadowed appearance beneath the cheekbones.
There’s a useful distinction here. According to PHI Clinic, a hollow cheek usually describes a shadow under the cheekbone where support has been lost, whereas a gaunt face means the effect has spread more widely, so the face reads as drawn overall.
In practice:
- Hollow cheeks — localised shadowing beneath the cheekbones
- Gaunt face — generalised volume loss across the midface, temples, and around the eyes
The distinction matters for treatment. Localised hollowing responds well to targeted filler. Generalised gauntness usually needs a broader approach.
What Causes Hollow Cheeks?
Ageing and Fat Pad Loss
The most common cause.
Your face contains distinct fat compartments that provide structure and fullness. With age these pads shrink and descend, while bone resorption reduces the underlying scaffold. The result is loss of support beneath the cheekbones.
This is compounded by declining collagen — see our guide on collagen production for why skin thickness reduces alongside volume.
Weight Loss — Including Weight-Loss Medication
Facial fat is lost along with body fat, and you can’t direct where fat loss occurs.
Cadogan Clinic specifically lists weight loss including weight-loss medication among the causes — a reflection of how common this has become with GLP-1 medications.
This isn’t a drug side effect. Rapid weight loss causes it regardless of method. Our guide on Ozempic face covers why speed of loss is the actual variable, and how weight loss affects your face explains the broader pattern.
Genetics
Some people naturally have very little facial fat and appear hollow even young. This is a structural characteristic rather than a change — and it means treatment expectations differ from age-related hollowing.
Smoking
Nicotine constricts blood vessels, reducing nutrient delivery to facial tissue, while tobacco chemicals accelerate collagen breakdown. Long-term smokers frequently show pronounced midface hollowing.
Dehydration and Poor Nutrition
Chronic dehydration and inadequate protein intake both affect how full the face appears. Neither causes structural fat loss on their own, but both worsen the appearance.
Lack of Sleep
Poor sleep affects circulation and tissue repair, and often exaggerates existing hollowing — particularly under the eyes and in the midface.
Sun Damage
Cumulative UV exposure degrades collagen and elastin, reducing skin thickness and support. See our guide on sun-damaged skin.
How to Fix Hollow Cheeks
Dermal Fillers
The most direct approach. Hyaluronic acid filler placed in the midface restores volume where it’s been lost, lifting the shadow beneath the cheekbones.
Results: immediate Duration: 12–18 months for cheek placement Reversible: yes, with hyaluronidase
Our guides cover the best facial fillers in Malaysia, how long fillers last by area, and why some fillers look more natural.
A note on technique: cheek filler is one of the areas where over-treatment is most visible. Conservative placement across sessions produces better results than trying to correct everything at once.
Collagen Biostimulators
Rather than adding gel, these prompt your body to build its own collagen — better suited to diffuse volume loss than targeted hollowing.
Results: gradual, over 3–6 months Duration: 18 months to 2 years Reversible: no
Our guide on collagen biostimulators compares Sculptra, Radiesse, Julaine, and Ultracol.
Which to choose: filler for a defined hollow you can point to; biostimulator for generalised thinning across the midface. Many treatment plans use both.
Fat Transfer
Fat harvested from elsewhere on your body, processed, and injected into the face.
Advantages: uses your own tissue, potentially permanent for the fat that survives Limitations: unpredictable survival rate (typically 50–70%), requires a donor site, more downtime
Usually considered for more significant volume loss rather than moderate hollowing.
Skin Boosters
Where the issue is skin quality — thin, crepey, dull skin making hollowing look worse — rather than volume itself, skin boosters improve hydration and texture.
They won’t fill a hollow. They’re a complement, not a solution.
What Doesn’t Work
- Facial exercises — you cannot exercise fat pads back into existence
- Cheek-plumping creams — no topical restores subcutaneous volume
- Deliberate weight gain — you can’t direct where fat is deposited, and often gain it elsewhere first
- Facial massage tools — temporary circulation effect, no structural change
Do You Actually Want Hollow Cheeks? Read This First
For those searching to create hollow cheeks, this section is the one worth reading.
Buccal Fat Removal
Buccal fat pads sit in the lower cheek. Removing them creates a more sculpted, hollowed appearance beneath the cheekbones — which is why the procedure has become widely discussed.
It is permanent. Buccal fat does not grow back.
The Warning From Plastic Surgeons Themselves
The American Society of Plastic Surgeons cautions against jumping into buccal fat removal, noting you may end up with a result you don’t want in the long run.
Here’s the mechanism behind that warning:
Your face loses volume naturally with age. Buccal fat removal accelerates that process permanently. A 25-year-old with full cheeks who removes buccal fat may look sculpted immediately — and gaunt at 45, when natural age-related volume loss compounds what was surgically removed.
The people in this clinic seeking cheek filler for hollowing are frequently dealing with exactly the appearance others are paying to create. That’s not an argument that nobody should have the procedure. It’s an argument for understanding that facial fullness is an asset that depletes on its own.
If You’re Considering It
- You cannot reverse it. Restoring the look requires filler or fat transfer indefinitely
- Your face will change regardless. Factor in what you’ll look like in 20 years, not just now
- Contouring makeup achieves a similar effect temporarily, with no permanence
- Weight loss to create hollowing affects your whole body and carries its own consequences
- Get assessed by someone who will tell you no if your facial structure doesn’t suit it
The Non-Permanent Alternatives
If you want more defined cheekbones without removing tissue:
- Cheekbone filler — adding projection to the cheekbone creates shadow beneath it, achieving definition by adding rather than removing. Fully reversible
- Contouring makeup — zero commitment
- Skin tightening treatments — improve jawline and midface definition without volume loss
The key insight: you can create the appearance of hollowing by enhancing what sits above it. That’s reversible. Removing fat isn’t.
When Hollow Cheeks Warrant Medical Attention
Occasionally, facial volume loss signals something requiring investigation rather than cosmetic treatment:
- Rapid, unexplained hollowing without weight loss or ageing
- Alongside unintentional weight loss
- With fatigue, appetite changes, or other systemic symptoms
- In someone with a history of disordered eating
In these cases, see a doctor before considering aesthetic treatment.
FAQ
What causes hollow cheeks? Most commonly ageing and facial fat pad loss, weight loss (including from GLP-1 medications), genetics, smoking, and cumulative sun damage.
Can hollow cheeks be fixed? Yes. Dermal fillers restore volume immediately, collagen biostimulators build it gradually, and fat transfer offers a longer-term option for more significant loss.
How much filler do I need for hollow cheeks? Typically 1–2ml per side depending on severity. Conservative placement across sessions produces better results than treating everything at once.
Is buccal fat removal a good idea? It’s permanent, and the ASPS cautions that the result may not be what you want long-term. Facial fat depletes naturally with age, so removing it accelerates a process that would happen anyway.
Can you get hollow cheeks back after buccal fat removal? Not naturally — the fat doesn’t regenerate. Restoring fullness requires filler or fat transfer on an ongoing basis.
Do facial exercises help hollow cheeks? No. Exercises may tone muscle but can’t restore lost fat pads or bone support.
Are hollow cheeks caused by weight-loss injections? Not by the medication directly. Rapid weight loss causes facial fat loss regardless of method — GLP-1 drugs simply make rapid loss achievable for more people.
Can I prevent hollow cheeks? Partially. Daily sunscreen, not smoking, maintaining a stable weight, adequate protein, and good sleep all slow the process. Genetics and ageing you can’t change.
Will gaining weight fill my cheeks? Possibly, but you can’t control where fat is deposited — most people gain it elsewhere first. Not a reliable approach.
Bottom Line
Hollow cheeks come from volume loss — through ageing, weight loss, genetics, or lifestyle. They’re treatable with fillers, biostimulators, or fat transfer, each suited to different patterns of loss.
And if you’re on the other side of this search, wanting to create them: buccal fat removal is permanent, plastic surgeons themselves caution about long-term regret, and your face will lose that volume on its own with time anyway.
Cheekbone filler achieves similar definition by adding rather than removing — and it’s reversible. That’s usually the better first step.
At CLÉO Clinic, facial assessments are carried out by LCP-certified doctors who will tell you honestly what your facial structure suits — including when a treatment you’ve asked about isn’t the right choice. See our treatable conditions, or book a consultation.
