Thermage genuine tip
The short answer
Use the checks the manufacturer's Korean office publishes. Solta Medical Korea describes a silver hologram sticker on the outside of each Thermage FLX tip box. The sticker carries a QR code and a 12-digit authentication number: scanning the code with a phone camera, or entering the number in the authentication section of the official Thermage FLX website in Korea, confirms whether the tip is a genuine product. The same office restricts each tip to a single patient.
Sources: Solta Medical Korea's announcement of its renewed authentication system (June 2024) and Rewind's device documentation, which lists Thermage FLX among the seven lifting devices at the clinic. The page explains a manufacturer's checks for one device and says nothing about any provider.
The tip is the part patients ask about because it is the part that gets used up. It clips onto the handpiece, touches the skin directly and is coded for a fixed number of pulses. A genuine, unused tip is what a Thermage quote pays for.
This page stays with one task: what you can check for yourself, what each check confirms, and what to ask when one of them is missing. How the device works is explained on the Thermage FLX overview.
What to look at
You need no technical background for any of them. Some are visible from the chair; the rest can be read once you are home.
Running the check
The verification itself takes a minute. What matters is running it with the sticker from your own tip.
Point the camera at the QR code on the hologram sticker. Solta Medical Korea describes the scan opening a genuine-product check on the phone itself.
On a computer, open the authentication category of the official Thermage FLX website in Korea and enter the 12-digit number from the sticker. The site is written in Korean, so a browser translation feature helps.
The office says any patient who has received a Thermage FLX treatment can run the check. Ask for the sticker, or a photograph of it, at the end of the session so the number is to hand.
A successful check confirms that the number belongs to a genuine Thermage product. It says nothing about how the energy was set or where it was placed, which are clinical questions for the doctor.

Why it matters
The tip is more than a cover for the handpiece. Solta Medical Korea has described the membrane inside it acting as a sensor that helps regulate how energy is delivered.
According to the manufacturer's Korean office, a tip is a one-patient consumable, because it sits against the skin and the accuracy and safety of the treatment depend on it being new.
The same office has told the press that when the membrane is damaged, heat cannot be spread evenly; energy can concentrate, the effect falls away and burns become possible.
At Rewind, Dr. Jonghwan Choi, a board-certified plastic surgeon, sets the shot count before the session, so the count on your plan and the count on the box can be read side by side.
During your visit

Fig. 04 · A treatment room on the clinic floors

Fig. 05 · Reception, Richro Building
The clinic occupies floors four and five of the Richro Building in Apgujeong, Gangnam, Seoul, and sees patients by appointment on Monday, Tuesday, Wednesday and Friday from 10:00 to 19:00 and on Saturday from 10:00 to 16:00. The examination comes first, and the count is agreed there. In the treatment room, before the first pulse, is the moment to see the sealed box, the sticker and the printed count. After the session, the sticker number is what you check online.
Mention at booking that you want to see the box opened so it is part of the plan for the day. Anaesthesia and session length are not published for this device at Rewind, so raise those at booking as well.
Pricing
Rewind prices each plan by the count of the tip opened for you. The figure and the check therefore point at the same object: the count you pay for is printed on the box you can inspect.
Value-added tax is added to each figure at payment, while any anaesthetic fee is already counted in. The list carries no separate tip charge. The 900-shot plan inside the elasticity package is quoted at consultation.
Checklist
The list assumes nothing about the provider and asks only for what the manufacturer's own system makes available. A genuine tip settles which part is used; whether Thermage suits your face is a separate judgement, and descended tissue, very thin skin, a pregnancy, a pacemaker or an infection on the face is raised before any plan.
Recovery
Verifying the tip changes nothing about recovery. Rewind's written instructions after Thermage are the same four points for every patient.
An authentic tip does not remove the known hazards of monopolar radiofrequency, among them surface burns, blistering, long-lasting redness, numb or tingling patches and, occasionally, thinning of the fat layer. Settings, placement and whether the face suits the device still decide most of the outcome.
At Rewind one board-certified plastic surgeon sets each Thermage plan and its count, and can account for the tip used on the day.

Scientific evidence
None of these papers studies whether a tip is genuine. They are listed for what monopolar radiofrequency, delivered as designed, has been reported to do and how its technique was refined. None was carried out at Rewind, and none predicts an individual result.
