- Ultherapy may be considered when skin laxity is the main issue, even on a thin face. First distinguish shadows caused by missing volume from skin that has actually loosened.
- If your cheeks are already hollow or your face changed after weight loss, show your clinician both the volume you want to preserve and the jawline you want to improve.
- There is no universal shot count that eliminates the risk of hollowing. Even a jawline-only plan requires consideration of the treatment area, skin and underlying tissue, energy and depth.
- Thermage is an alternative to compare, but it is not risk-free. With any treatment, ask about both the change you can reasonably expect and possible adverse effects.

Why does my jawline look saggy when there is little fat on my face?
A thin face and firm tissue around the jawline are different things. Aging and weight changes affect skin elasticity. Even with little cheek volume, skin beside the jaw can loosen or the contour below the mouth can look different.
At your consultation, explain exactly what changed instead of stopping at “my face is thin.” Loose skin beside the jaw, tissue descending beside the mouth, and an indistinct jawline with little under-chin fat describe different concerns.
If your profile bothers you more than the front view, show photographs from that angle too. Lighting and camera angle should be distinguished from a real change. Appearance alone does not let you diagnose a particular fat layer or ligament as the cause.
This reviewer was concerned about jawline shape rather than overall body weight. Saying that their body was not overweight does not establish that their facial fat layer was thin.

What should I check first if my cheeks are already hollow or my face sagged after weight loss?
First have the hollow areas and sagging areas assessed separately. Explain the change you want and the change you want to avoid: for example, “I do not want the area below my cheekbones to look thinner, but I want to improve the loose area below my mouth.”
Mention recent weight loss, whether the same hollowness appears in older photos, and any cheek liposuction or fat grafting. Comparing photographs before and after weight changes or treatments helps explain existing hollowness versus a recent concern.
If hollowness is your main concern, ask whether lifting the jawline alone would create the appearance you want. If a volume treatment is proposed, ask which area it addresses, why it is proposed, and what risks that treatment carries.

Can Ultherapy make my cheeks look more hollow?
Fat or volume loss is included in the manufacturer’s post-market adverse-event information. Cheek-hollowing concerns should therefore not be dismissed as rumor. The US instructions for both the original Ulthera system and Ultherapy PRIME discuss these reports.
The documents also explain that voluntary reports alone cannot reliably establish incidence or causation for individual cases. They do not justify saying that every thin person will develop hollow cheeks or that a specific percentage will experience this problem.
Before treatment, show the exact hollow area and ask whether there is a reason to treat it. If a new depression, asymmetry or persistent altered sensation develops afterward, have it assessed by your treating clinician before adding another treatment.

Can I treat only my jawline and leave my cheeks alone? Are 300 shots safer?
Treatment areas can be discussed and adjusted, but the number “300 shots” alone cannot establish safety. A total shot count does not explain where the treatment is delivered, at what depth or with what energy. Receiving less treatment and receiving a suitable plan are different matters.
Ultherapy imaging is used to view tissue beneath the skin, check contact and confirm treatment depth. Viewing an image does not remove the possibility of adverse effects. The decisions made using that image remain important.
This reviewer described their experience from treatment design through the procedure. Ask how your own treatment plan would distinguish areas to treat from volume to preserve.
Ask, “How will you handle the areas where I want to preserve volume?” and “What determines the treatment allocation for my jawline?” These questions are more specific than applying another person’s shot count and price to your face.

How much can my jawline change, and when should I expect a difference?
Check whether gradual improvement in firmness and contour matches your goal rather than expecting a surgical-size change. The American Academy of Dermatology describes non-invasive ultrasound tightening as modest, with results generally developing over two to six months. Substantial sagging may exceed what these treatments can achieve.
The systematic review linked at PMID 39540440 included 42 studies. Pooled satisfaction was 84% in 326 participants, while studies offering a neutral response option reported 62% in 172 participants. These figures come from different groups of studies, not a before-and-after comparison of the same patients.
Do not read these percentages as your probability of satisfaction with Ultherapy on a thin face. The researchers also noted that the way neutral responses were handled could overestimate satisfaction.
This excerpt describes immediate swelling and anticipation rather than a final outcome. The “about a week” mentioned by the reviewer is not a guaranteed recovery time for everyone.
When comparing reviews, check whether they describe the day of treatment, several weeks later or several months later. Also look for concurrent treatments and photographic angles. Clarify whether you want a subtle improvement beneath the jaw or a large change comparable to pulling the skin upward by hand.

Would Thermage or another lifting treatment be better if I worry about hollow cheeks?
Thermage is an option to compare, but there is insufficient basis to say it is always more suitable for thin faces. Ultherapy uses ultrasound and Thermage uses radiofrequency. Ask what each treatment is intended to change in your case and how each plan would differ.
Thermage’s safety information includes burns and surface irregularities after treatment. These materials do not let us calculate a rate of fat loss, but they also do not support a promise of treatment without hollowing concerns or adverse effects.
If skin laxity is central, compare the expected benefits of energy-based treatments. If hollowness is central, have the volume issue assessed separately. For marked sagging and a large desired change, discuss the limitations of non-surgical options alongside the scars and recovery burden of surgery.
Do not group thread lifting, skin boosters and botulinum toxin together as interchangeable alternatives. If another procedure is proposed, ask “Which part of my concern is this intended to improve?” and “Why would you recommend it before the treatment I originally considered?”

What if I previously had Shurink, InMode or filler?
Start with the treatment name, area, date and changes you noticed afterward. A history of lifting treatment alone does not determine when another procedure is appropriate or how much of the same area should be treated.
Tell the clinician about filler or implants in particular. The US Ulthera instructions include precautions such as not recommending treatment directly over areas with dermal filler. Also mention wounds or skin conditions in the area, medications, and pregnancy or breastfeeding.
If your cheeks looked more hollow after a previous treatment, bring dates and photographs. Without an assessment, do not assume that treatment caused the change or that adding another lifting procedure will resolve it.
What should a clinic explain during my consultation?
Look for an explanation that distinguishes the volume you want to preserve from the sagging you want to improve. Beyond the device name and authenticity information, check who will actually perform treatment and whether that person explains your treatment areas.
The clinician’s specialty and current affiliation, device model and method of checking an authentic tip are separate facts. An authenticity statement does not establish suitability for your face, and a specialist credential does not guarantee a particular result.
When looking at examples, ask about existing hollowness, treatment areas, concurrent procedures and photo timing as well as whether the face is similarly thin. A clinic’s explanatory column and an individual patient’s progress record are different kinds of material. Clinic columns here illustrate consultation approaches; they are not a basis for ranking clinics.
After the consultation, check whether you can explain the treatment goal and limitations in your own words. If your main concern was hollowing but you only remember the price and shot count, ask for a clearer explanation before paying.

What should I ask during the consultation?
- Is my jawline concern primarily skin laxity, volume deficiency or tissue beside the mouth?
- How will you handle existing hollow cheeks and temples in the plan?
- Can you show me the areas you intend to treat and avoid?
- Why are you choosing this shot count and treatment depth for me?
- What tissue and treatment depth do you check on the ultrasound image?
- Who will perform treatment, what device model will be used, and how can I check the tip’s authenticity?
- How would Thermage, another option or postponing treatment differ?
- When will we compare photographs, and what degree of change is realistic?
- Who should I contact for hollowing or altered sensation, and how will it be assessed?
- Does the quote include VAT, anesthesia, additional treatments and follow-up care?
Where should I start in my situation?
| My situation | What to discuss first |
|---|---|
| The skin beside my jaw is loose, but cheek hollowness is limited | Discuss the degree of laxity and the change reasonably expected from non-surgical treatment. |
| My cheeks are hollow below the cheekbones, while tissue descends beside my mouth | Assess hollowness and descending tissue separately, and identify volume you want to preserve first. |
| There is little under-chin fat, but my profile lacks definition | Assess what makes the contour indistinct before choosing a treatment. |
| My face changed after weight loss or a previous procedure | Bring your weight and treatment history and earlier photographs. |
| Sagging is substantial and I want a clear lift | Compare non-surgical limitations with the burden of surgical options in the same discussion. |
Preserve volume and define the jawline concern
The starting point for Ultherapy on a thin face is “What do I want to preserve, and what do I want to change?” rather than “How many shots should I buy?” Show existing hollow areas first, then discuss the cause of the jawline concern and the actual treatment area. Use that explanation to compare Ultherapy, another treatment and postponement.

Is Ultherapy too early for someone in their 30s with a thin face?
Being in your 30s alone does not determine suitability. The degree of sagging, existing cheek hollowness and your desired change are more specific consultation criteria.

Can I consult about my profile if my face looks fine from the front?
Yes. Show the angle that bothers you and have the jawline contour, loose skin and existing facial shape assessed together. One profile photograph alone does not determine whether Ultherapy is suitable.

Should I limit treatment to 300 shots if I am afraid of hollow cheeks?
Choosing a total shot count alone does not answer that concern. Have the tissue and treatment location and extent assessed, then ask for the reasoning behind the plan.

Does Ultherapy PRIME remove the risk of cheek hollowing?
The US PRIME instructions also include fat or volume loss in post-market reports. A newer model does not establish that an individual’s risk has disappeared.
Can I rely on a review saying the jawline changed within days?
Read it as that reviewer’s early impression rather than a final result. Check observation time, swelling and concurrent procedures; society guidance describes gradual change over months.
Do I need both Ultherapy and Thermage for a better result?
An individual’s combination-treatment review does not prove that receiving both is better. Ask which concern each treatment addresses and why another procedure is being added rather than using one alone.
Sources: Thermage: safety information
Can I feel reassured if another reviewer had no hollowing?
Another person’s experience without that problem cannot predict your risk. Compare existing hollowness and treatment history, and check official safety information and your clinician’s explanation separately.
