Who it suits
- Dermal laxity of the cheeks and jawlineVolumetric RF heating at a depth comparable to Thermage.
- Eyelid and periorbital laxityDedicated eye tips, developed from the physician's own lecture work on Eye Xerf.
- Patients comparing radiofrequency platforms on priceA newer monopolar RF option available at a different price point.
What it does
Xerf delivers monopolar radiofrequency that heats the dermis volumetrically while the surface is kept cool, contracting existing collagen immediately and stimulating new collagen formation over the following months. Its dedicated eye tips allow treatment close to the orbit, which is often where laxity becomes visible first.
How it is planned here
Following the Meta-Vu scan, Xerf is weighed against Thermage FLX and Alltite based on skin thickness, treatment area and budget. The physician here lectures to other dermatologists on the clinical application of Eye Xerf, and the eye protocol used in this clinic follows that same approach.
What to expect
Expect mild redness for a few hours after treatment. Tightening builds over two to six months and is typically maintained for a year or more.
Questions
Xerf or Thermage?
Both are monopolar RF. Thermage has the longest record; Xerf is a newer platform with its own tip range. The dermatologist compares them for your face at consultation.
Downtime?
None.
Does it hurt?
Numbing cream and surface cooling keep it tolerable.
I have never had a lifting treatment. Where do I start?
With a consultation and a 3D Meta-Vu scan, not with a device. The dermatologist shows you on screen where your face has lost volume and where the skin has loosened, then explains which single treatment, if any, would change what you see. Many first-time patients leave with one treatment, not a package.
Does lifting hurt, and will I look different the next day?
Numbing cream is applied for 20 to 30 minutes first. Ultrasound treatments feel like brief deep heat; radiofrequency feels like warm pulses. Most patients go to dinner the same evening with no visible sign of treatment. Any mild redness is gone within hours.
How long before I see a result, and how long does it last?
Some tightening is visible early, but the main result builds as new collagen forms over two to three months. One treatment typically holds for a year or more, after which it is repeated as the face requires.
Can I do it on the day of my consultation?
Yes for Ultherapy, Thermage, Sofwave, Xerf and ONDA. Allow about two hours including the scan, numbing and treatment.
What does it cost?
Prices are published on this site in Korean won and depend on the shot count, which is decided from the scan. Ultherapy Prime starts at ₩450,000 per 100 shots and Thermage FLX at ₩1,450,000 per 300 shots. Cosmetic treatment carries 10% VAT.
