Quick answer
Thermage is a monopolar radiofrequency device that heats the dermis through cooled skin; the US FDA cleared the FLX in 2017 for wrinkles, including around the eyes, and a quote depends on the tip, the area and the operator.
- What it is: monopolar radiofrequency with surface cooling, delivered through a disposable tip.
- What the FDA cleared: the FLX System on 22 September 2017, for non-invasive treatment of wrinkles and rhytids, with periorbital use including the upper and lower eyelids named.
- What studies report: improvement in wrinkle scores and brow position in an early periorbital trial, with a burn rate of 0.36 per cent of applications, and pain scores of about 6 to 7 out of 10 in two later reports.
- What decides a quote: the tip, the area, the number of pulses, the operator and the follow-up, not a single list price.
- The Retreat Clinic does not offer Thermage; Dr Ong performs XERF, another monopolar radiofrequency device.
What is Thermage, and how does it work?
Thermage is a brand of monopolar radiofrequency device. Current passes from the handpiece through the tissue to a return pad elsewhere on the body, the dermis heats, and the surface is cooled so the skin is not burned. The FDA summary for the FLX describes energy delivered from a disposable tip, with the system monitoring skin contact, and the earlier CPT summary describes the same approach as selective coagulation of tissue while conductively cooling the epidermis.
The aim is a gradual change in the skin over weeks to months rather than an immediate one. A systematic review of 121 articles on radiofrequency for the face and neck found improved laxity and elasticity, histological changes consistent with a repair response, and higher satisfaction in people who wanted modest change. That review covers radiofrequency in general, so it supports the technology rather than any one brand. The comparison article on Thermage and XERF explains the frequencies and cooling methods in more detail.
Is Thermage FDA approved, and what do the studies report?
The US FDA cleared the Thermage FLX System on 22 September 2017, and the FDA database lists earlier Thermage systems cleared through the same 510(k) route since 2000. The letter finds the device substantially equivalent to legally marketed predicate devices, which is a different finding from a head-to-head trial, and the indications are for the non-invasive treatment of wrinkles and rhytids. With the vibration handpiece, the listed uses also include temporary improvement in the appearance of cellulite and temporary improvement of local circulation. The word is clearance, not approval, and it concerns the listed uses rather than a promise for a particular face.
The periorbital trial is the nearest to the eye question. Eighty-six people had one treatment with an early Thermage system and were followed for six months. Independent scoring of blinded photographs found an improvement of at least 1 point on the wrinkle scale in 83.2 per cent of treated periorbital areas, whereas the treating physicians, without the before photographs, noted improvement in 28.9 per cent of areas. Half of the subjects (41 of 82) were satisfied or very satisfied, and 61.5 per cent of eyebrows (40 of 65) were lifted by at least 0.5 mm. That device is an earlier generation, and the figures do not transfer to the FLX.
A physician survey of 5,700 monopolar radiofrequency treatments reported tightening at six months in 54 per cent with the original high-energy single pass and 92 per cent with a lower-energy multiple-pass method. A survey is not a controlled trial, and its abstract does not name the device. A 2013 survey of 64 patients treated with a vibration handpiece found 80 per cent reported at least mild correction of laxity. None of these sources followed people beyond ten months.
Does Thermage work around the eyes?
The FDA indications for the FLX name periorbital wrinkles and rhytids, including the upper and lower eyelids, for the radiofrequency-only components. Trial evidence for the eye area comes from the 2003 study above: improvement on blinded scoring in most treated areas, a modest brow lift, and a second-degree burn rate of 0.36 per cent of applications (21 of 5,858), with three people left with small areas of scarring at six months.
Those burn and scar figures are the reason the eye area is a decision for the treating doctor and not a menu item. Skin there is thin, the margin for error is small, and settings and technique matter. The Retreat Clinic does not offer Thermage. Dr Ong performs XERF, which treats the face, jawline, brow and neck; eyelid skin is not treated with XERF at present, and the small XERF eye tips are due at this clinic with no date set. The XERF page describes what it is used for.
Does Thermage hurt?
Most reports describe it as uncomfortable rather than trivial. In a study of 46 patients, pain on a 0 to 10 scale within five minutes was 7.12 on the left side of the face and 6.62 on the right, and younger patients (42 or under) reported more pain than older ones. In the 2013 survey of 64 patients the average was 6.06 and 9 per cent found it too painful. The first physician survey found 45 per cent too painful with a high-energy single pass and 5 per cent with a lower-energy multiple-pass method.
Two of those abstracts do not name the device, so the figures describe monopolar radiofrequency as used in those studies, not a promised experience. Comfort depends on the energy, the number of passes, the cooling and any numbing, which is why the protocol is worth asking about. For another device with a published comfort record, the XERF side effects article sets out what is known.
What decides the fee for Thermage in Malaysia?
No price is published here, because the quote is built from several parts, and a headline figure rarely shows which parts it includes. The parts are these.
- The tip. The FDA summary describes energy delivered from a disposable tip, and the tips come in different sizes for the face, the eye area and the body, so a single-use item sits inside the quote.
- The area. A full face and neck uses more pulses than the eye area alone, and the number of pulses is how most protocols count work done.
- The passes. A low-energy multiple-pass approach and a single high-energy pass are different amounts of work, and the survey above found different pain and tightening rates for them.
- The operator and the setting. Who holds the handpiece, how the energy is set to the person in front of them, and whether numbing is used are all part of what is being paid for.
- The follow-up. Whether a review or a repeat session is included changes the true cost of a course.
Asking what is included, whether the tip is counted per treatment, and what a second session would involve makes two quotes comparable. A low quote is not a flaw and a high one is not a promise.
What are the device and operator rules in Malaysia?
Every medical device supplied in Malaysia must be registered with the Medical Device Authority, and the register is public, so the device can be checked by its registration number. Separately, the Medical Device (Designated Medical Device) Order 2026, in force since 1 June 2026, requires a permit to operate the devices it names, which are medical lasers, HIFU and liposuction devices. The article on the Order reads it closely, including the point that radiofrequency devices are not named in its schedule, so the operator permit is not the check that applies to them.
That leaves three questions a patient can still ask: is the machine registered, who is operating it and with what training, and which doctor is making the diagnosis and choosing the treatment. A device outside the schedule is still a medical device, and registration still applies.
How does Thermage compare with XERF and other devices?
The two are monopolar radiofrequency devices that differ in frequency, cooling and tips, and no study has compared them directly, so neither the tightening nor the comfort can be ranked on evidence. Thermage delivers one frequency, 6.78 MHz, and XERF delivers 6.78 MHz and then 2 MHz within a single pulse, as the comparison article reports. Other registered monopolar devices have their own small studies, and the same limit applies: results from one device do not carry over to another.
To put the clinic position once and plainly: The Retreat Clinic does not offer Thermage. Dr Ong performs XERF, which treats the face, jawline, brow and neck. The article on who XERF is for, and who it is not sets out the selection questions that apply to monopolar radiofrequency generally, including skin, laxity and expectations.
What should I expect, and what do the studies not show?
Expect a gradual, modest change, not a surgical lift. The review of 121 articles found higher satisfaction among people who wanted modest improvement, and the trials above followed people for six months and, in surveys, up to ten, which is not the same as years. No source read measured results in Malaysian patients, so none is claimed, and none of the sources read compares one brand with another. A claim of an assured lift or a result that lasts for a stated number of years goes beyond what these studies show.
