Hollow Cheeks After Lifting: Why They Happen and How to Reduce the Risk
Worry about hollow cheeks makes many people hesitate before lifting treatment. Hollowing usually depends less on the device itself than on whether the treatment depth and areas match how fat is distributed in your face. The most useful precaution is to assess skin thickness and fat volume beforehand, then skip lean areas or treat them more gently.
Why can cheeks look hollow after lifting?
Lifting devices use heat to stimulate collagen; with some devices, that heat also reaches fat. A 2025 review of high-intensity focused ultrasound (HIFU) explains that ultrasound-induced heat both stimulates collagen renewal and reduces fat-cell size. This can slim a fuller face, but concentrating heat beneath the cheekbones or in the lateral cheeks where fat is already sparse can leave a hollow.
The same review notes that complications can occur even with minimally invasive HIFU. In many cases, hollowing reflects a treatment plan that did not fit the face, rather than the device itself.
Is lifting always the cause?
No. A 2024 review of facial aging describes fat loss in specific compartments as a major cause of structural aging. The cheeks may already be losing volume gradually; lifting the sagging tissue can simply make those existing hollows easier to see.
Weight changes also matter. A 2025 imaging study of patients taking weight-loss medication found that midface volume fell by approximately 7% for every 10 kg lost, mainly in the superficial fat layer. We plan more cautiously when a patient is dieting or has recently lost substantial weight.
Common causes of cheek hollowing
The people and areas at risk, and the best response, depend on the cause.
| Cause | Who or where is most affected | Prevention and management |
|---|---|---|
| Excessive heat in the fat layer | Lean areas below the cheekbones and in the lateral cheeks | Reduce depth or intensity, or leave the area untreated |
| Repeated treatment in the same spot | Too many pulses or lines concentrated in a small area | Distribute treatment evenly across each area |
| Age-related fat loss | People in their 40s and older, especially with naturally lean faces | Plan volume restoration alongside lifting |
| Rapid weight loss | People currently dieting or who have recently lost weight | Plan after weight stabilizes; consider a skin booster |
| Excessive contour or fat-dissolving injections | Repeated injections in cheeks with little fat | Assess fat volume before choosing dose and frequency |
How can hollowing after Ultherapy be avoided?
Ultherapy sends ultrasound energy as deep as the SMAS, so selecting the depth matters. Ultherapy PRIME uses real-time ultrasound imaging to check tissue thickness, allowing the doctor to identify thin fat layers and adjust the depth. A 2023 review of ultrasound lifting studies found that most adverse effects were mild bruising, redness, or pain that resolved within 2–3 days. This ultrasound lift often suits patients with pronounced nasolabial or marionette folds, or those disappointed by how briefly previous lifting results lasted. We first identify the layer where sagging begins. One first-time patient told us their jawline began to feel lifted after a few days.
Can Titanium lifting also cause hollowing?
Titanium lifting uses three laser wavelengths (755, 810, and 1064 nm) with little discomfort and no downtime. Its STACK mode targets deeper tissue and SHR targets the dermis. Slimming is one of its main effects. For a lean face, we vary the mode by area and reserve deeper treatment for thicker fat. Tell us at your consultation if your cheeks are already lean and you are worried about hollowing. This laser lift is especially popular with patients preparing for a wedding, anniversary, or other event.
Is ONDA suitable for a face with little fat?
ONDA delivers 2.45 GHz microwave heat from the dermis down to the fat layer. The shallow 3 mm handpiece contracts collagen, while the deeper 7 mm handpiece promotes fat-cell breakdown. This is useful for double chins and sagging cheeks, but lean faces need a plan built around the shallow handpiece. When patients say the treatment did little, the same settings have often been used repeatedly without assessing fat thickness and sagging, and hollowing can result from the same oversight. Experience matters. We also screen for cardiovascular, liver, and kidney disease, tumor treatment, pregnancy, and breastfeeding, any of which rules out treatment.
How does Dong-An Joongsim Clinic reduce the risk?
At Dong-An Joongsim Clinic, your doctor personally assesses your face, conducts the consultation, and performs the treatment, identifying fuller and leaner areas before deciding where to deliver energy.
Dr. Soyoun Koo, recognized by El.En and DEKA as Korea's first ONDA LIFTING EXPERT MEMBER, assesses skin thickness, fat volume, and where sagging occurs to plan ONDA skin tightening treatment with the 3 mm and 7 mm handpieces. Dong-An Joongsim Clinic is a certified Ultherapy provider and issues a certificate confirming genuine treatment after each procedure. We also received the Alma Elite Award from the manufacturer of Titanium lifting . When cheeks are already hollow, we recommend restoring volume in the lateral cheeks and beneath the cheekbones with HILO WAVE before adding lifting. This combination can also help if you are concerned that device results fade quickly. One patient who received ONDA and HILO WAVE together said the combination seemed to work well and their face looked more defined. For patients preparing for a photo shoot at short notice, we choose a combination intended to give an immediate improvement without swelling or redness.
What else should you know?
Fat volume and skin thickness vary, so the same plan can produce different results. Cheeks may temporarily look hollow as post-treatment swelling settles; allow a few weeks before judging the result. Established hollowing can be addressed with volume-restoring treatment, but recovery takes time.
Cheek hollowing: common questions
How should I choose a lifting clinic in Apgujeong, Gangnam, Seoul if I am worried about hollowing?
Look for a doctor who personally assesses facial fat and varies treatment depth by area. At Dong-An Joongsim Clinic, your doctor provides both the consultation and treatment.
Will hollow cheeks return to normal?
A temporarily hollow appearance related to swelling usually settles naturally within a few weeks. When fat has been lost, skin boosters or collagen stimulators can help restore volume.
Can I have lifting treatment if my face is thin?
Yes. We focus on shallower depths that target the dermis rather than fat, and add volume-restoring treatment if needed.
Can contour injections cause hollowing for the same reason?
Yes. Injecting too much fat-reducing solution into an already lean cheek can produce a similar hollow. We assess fat volume before injecting.
What determines the cost of lifting treatment?
Cost depends on the device, number of pulses or lines, treatment areas, and whether volume restoration is included. We explain the cost after your doctor's assessment.
