How do Ultherapy and Thermage heat tissue differently?
Ultherapy focuses ultrasound waves at set depths beneath the skin, creating small, well-defined points of heat. Thermage converts radiofrequency energy into heat through the tissue's electrical resistance and spreads that heat across a broader volume, while the skin surface is cooled. Both aim to stimulate collagen production, but they get there in different ways.
With Ultherapy, ultrasound energy is concentrated at a set depth, much as a magnifying glass gathers light into a single point. When energy is delivered, millimetre-sized points of heat are lined up at that depth, while the tissue between them and the skin surface are relatively spared. Transducers focusing at different depths allow more superficial and deeper layers in the same area to be targeted separately. Distinctively, the practitioner can watch the layers beneath the skin on an ultrasound image while working. This imaging helps confirm that energy reaches the intended tissue rather than a structure such as bone, and each line follows the planned treatment map. As tissue thickness varies by area, imaging also guides the choice of transducer.
With Thermage, energy travels from a single tip towards a grounding pad placed on the body, and along the way the tissue's resistance converts it into heat. The resulting heat is volumetric rather than point-like: the tip heats the tissue beneath the area it touches more diffusely. Before and after each pulse, the tip cools the skin surface, helping to protect it. A temporary grid drawn on the treatment area helps distribute the pulses evenly. The heat causes an immediate contraction of collagen fibres, followed by a repair process that develops over months. This diffuse heating means an effect spread across a wider area of the skin itself is intended.
Which layers do they reach, and why does the difference in depth matter?
Ultherapy's deeper transducers can reach the superficial muscular aponeurotic system (SMAS), the layer also addressed in a surgical facelift. Thermage mainly targets the deep dermis and the connective tissue bands beneath the skin. Ultherapy is therefore considered more for laxity of the deep supporting tissue, and Thermage for the firmness and quality of the skin itself.
Facial laxity does not always come from the same layer. In some people, skin quality is relatively well preserved while the supporting tissue beneath loosens; a softening jawline, fullness under the chin and a slightly lowered brow are examples. In others, the main change is in the skin itself: it thins, loses elasticity, and fine wrinkles and a crêpey look become more visible. Focused ultrasound, which can target the deep layer, is discussed more often in the first picture, and radiofrequency, which heats the dermis and connective tissue bands diffusely, in the second. At consultation, gently lifting the skin to assess its thickness and elasticity helps make this distinction. These tendencies are not fixed rules and can vary between people.
The difference in depth also has safety implications. In people with very little facial fat, unwanted volume loss has been described with focused ultrasound aimed at deep layers, so transducer and depth selection are made with care. With radiofrequency, heat spreads diffusely, so the energy level is adjusted to how the person feels; changes in the fat beneath the skin have been reported rarely. For very thin-skinned areas such as the eyelids, Thermage has dedicated eye-area tips, whereas Ultherapy is applied to the brow line rather than to the eyelid itself. The position of any filler, threads or metal implants in the area is also taken into account when choosing depth and energy. These differences explain why the choice varies by area.
Who might each suit, and what are the limits of both?
For mild to moderate laxity arising from deeper tissue at the brow line, jawline, under the chin and on the neck, Ultherapy is discussed more often; for thinning skin, fine wrinkles, a crêpey look and mild laxity of the eyelid skin, Thermage. Neither replaces lost volume, removes significant excess skin or aims at the change a surgical facelift provides.
For example, in someone with good skin quality who notices that their jawline is starting to lose definition, Ultherapy, which targets the deep supporting tissue, may be discussed. In skin that has thinned across the face and neck, carries sun damage and shows fine wrinkles, the diffuse heat of Thermage may be more relevant. The neck is assessed for both devices, and Thermage is also known to be used on some body areas. Because the same person may have both needs, the decision is based not only on the complaint but on the layer and skin structure seen at consultation. Your pain threshold, the time you can set aside for recovery and your response to previous treatments can also influence the choice.
The limits of the two devices are similar. For volume loss at the cheeks, temples or under the eyes, filler or biostimulators may be more relevant, and botulinum toxin for expression lines. With advanced sagging and significant excess skin, neither focused ultrasound nor radiofrequency replaces surgery, and a plastic surgery opinion may be advised. Medical history also narrows the choice: a pacemaker or implanted defibrillator is an important contraindication for monopolar radiofrequency devices such as Thermage, and with focused ultrasound, implants in the treatment area are also assessed individually. Both treatments are usually postponed during pregnancy and breastfeeding, and your full medication list is reviewed beforehand. With an active infection, cold sore or open wound in the area, treatment waits until it has healed.
What feels different during and after treatment?
With Ultherapy, a deep, brief warmth or prickling is felt as energy is delivered, and this can be more noticeable near bone. With Thermage, each pulse brings a short burst of intense heat across the surface, followed immediately by cooling. After either treatment, most people return to their daily routine the same day.
How intense the discomfort feels varies with the person, the area and the energy level. With Ultherapy, the sensation depends on the depth of focus and the thickness of the underlying tissue, and may be more noticeable close to bone, such as along the jawline and forehead. With Thermage, the energy level can be adjusted during treatment according to your feedback. For both, pain relief or other comfort measures can be planned by the physician in advance. The length of the procedure depends on the size of the area treated and increases when the face and neck are treated together. Knowing in advance how long it will take, and where the sensation may increase, makes the process more predictable.
After Ultherapy, mild redness and swelling usually settle within a few days, while tenderness to touch can last a few weeks in some people; occasionally, mild bruising appears along the lines. After Thermage, redness usually clears within a few hours to a few days; rarely, marks matching the grid lines or small blisters have been reported. Temporary numbness and burns are among the rare risks with both devices. Make-up and daily skincare can usually be resumed soon, and sun protection is advised. If swelling is noticeable, pausing activities that raise body heat, such as saunas and intense exercise, for the first day or two may be suggested. If you notice unexpected pain, blistering or colour change, contact your physician.
Is there a difference in when results appear and how long they last?
Not a marked one. With both devices, change linked to collagen production begins within weeks and usually develops gradually over several months. Both are often planned as a single session; how long the effect is maintained varies with age, skin quality and lifestyle, and the timing of any maintenance treatment is decided individually.
The tightness felt straight after Thermage is largely linked to the immediate contraction heat causes in collagen fibres and to mild swelling, and this early appearance may fade quickly. With Ultherapy, no noticeable change is expected immediately after treatment. In both, the real change depends on new collagen production and in many people develops over a few months, continuing in some for up to six months. A review is therefore planned a few months later to assess the result, with comparison based on photographs taken before treatment in the same light and from the same angle. Agreeing before treatment on which change is being targeted, and in which area, also makes the result easier to assess.
How long the effect lasts cannot be expressed as a fixed ranking between the two devices. Age, skin thickness, sun damage, smoking and significant weight changes are the main factors affecting how well the result is maintained. Because tissue continues to age, a maintenance treatment may be discussed after a while; its timing depends on the response to the previous treatment and current examination findings. When the effect fades, the face is not expected to become looser than before treatment; the tissue simply continues along its normal course of ageing. Regular sun protection and avoiding smoking help maintain the result with either method. Which device is chosen for maintenance is also reassessed according to the change most prominent at that time.
Can Ultherapy and Thermage be used together?
Yes, in some plans the two devices are used together to complement each other: Ultherapy targets the deep supporting tissue, and Thermage the skin itself and its quality. They are reported to be planned on the same day or at different times; whether combining is needed, and the order and spacing, are decided by the physician based on examination findings.
The rationale for combining is to treat each layer with suitable energy in faces where laxity affects more than one layer. For example, a softening jawline arising from deeper tissue and thinned skin across the face may coexist in the same person. However, combining is not necessary for everyone; where one device can deliver the intended change, adding a second treatment increases recovery time and cost without always adding benefit. When both are done on the same day, swelling and tenderness may be more noticeable, so in some plans the treatments are spaced a few weeks apart. The decision to combine rests on whether the change achievable with a single device would meet your expectations.
When choosing, the real question is not which device is stronger but in which layer the problem lies. At consultation, your face is examined from different angles and with expressions, skin thickness and elasticity are assessed by hand, and fat distribution and volume loss are reviewed. Where volume loss predominates, injectable options rather than devices may be discussed, and with advanced sagging a surgical opinion. Genuine devices, known registration status in Türkiye and treatment in a licensed healthcare facility under a physician's responsibility are the basis of a safe process. It is also reasonable to ask for the exact name and model of the device to be used. You are encouraged to take time to have your questions answered before deciding.
Frequently asked questions
Does Ultherapy or Thermage hurt more?
Discomfort varies from person to person, but some people describe the deep heat of Ultherapy near bone as more intense. With Thermage, cooling follows the brief heat of each pulse, and the energy level can be adjusted to your feedback. Because numbing creams act near the surface and may do little for Ultherapy's deep heat, options such as oral pain relief are discussed in advance.
My face is thin with little fat. Should I consider Ultherapy or Thermage?
In a thin face with little fat, both Ultherapy and Thermage are planned more cautiously. With Ultherapy, unwanted volume loss has been described with deep transducers, so transducer and depth are chosen carefully; with Thermage, fat changes have also been reported rarely. In such faces the main concern is often volume loss rather than laxity, so filler or biostimulator options may come to the fore.
Should I consider Ultherapy or Thermage for a loose neck?
On the neck, the choice depends on the type of laxity. Ultherapy is discussed more often for mild to moderate laxity arising from deeper tissue under the chin and on the neck, and Thermage for thinning, crêpey neck skin. Botulinum toxin may suit neck bands, and skin-quality injectables or filler horizontal neck lines; with marked skin sagging, both devices have a limited effect.
How do Ultherapy and Thermage differ for a low brow and loose eyelids?
Ultherapy can be used to target the tissue supporting the brow when it has dropped slightly, but it is not applied to the eyelid itself. Thermage has eye-area tips designed for mild laxity and fine lines of the eyelid skin, and that treatment requires eye protection. With marked excess eyelid skin or true drooping of the eyelid, Ultherapy and Thermage have a limited effect.
I've had Ultherapy before. Can Thermage be chosen next time?
Yes, having had Ultherapy before does not rule out Thermage next time, and the reverse is also true. The choice depends on your response to the previous treatment and the change most prominent at that time: laxity in the deeper tissue, or thinning of the skin. The time between treatments and any filler or threads in the area also affect the plan.
Do different factors affect the cost of Ultherapy and Thermage?
Partly. For both devices, the size of the treated area is a key factor. With Ultherapy, the transducers used and the number of lines delivered define the scope of the plan; with Thermage, the tip type and number of pulses do, and Thermage tips are known to be single-use. Clear information can be given once the areas and extent of treatment are decided at consultation.
Can I have Ultherapy or Thermage if I have a pacemaker or a metal implant?
A pacemaker or implanted defibrillator is regarded as an important contraindication for monopolar radiofrequency devices such as Thermage, which is generally not advised in that situation. For Ultherapy, manufacturer information is reported to include warnings about active electronic or metal implants in the treatment area. The type and position of any implant are therefore discussed in detail at consultation, with a specialist opinion if needed.
If I'm planning to lose weight, should I wait before Ultherapy or Thermage?
If significant weight loss is planned, waiting until your weight has largely stabilised before Ultherapy or Thermage is often more sensible. Rapid, marked weight loss can change facial fat distribution and laxity, which shifts the aim of the planned treatment. Because the main concern after weight loss is often volume loss, injectable options may be discussed alongside devices.
