Greetings! This is Seye clinic, dedicated to all aspects of beauty.
"Which is firmerâUltherapy or Thermage?" "I heard that XERF is less painful these days. Among the three, which is best?" These are some of the most frequently asked questions we receive in our clinic. XERF, Ultherapy, and Thermage are all leading devices for lifting and improving skin elasticity, but they use different technologies and produce unique experiences. Today, we will professionally compare these top three lifting procedures in Gangnam.
XERF uses a dual monopolar radiofrequency system, combining 6.78 MHz and 2 MHz RF frequencies. Much like layering different sounds in an audio mixer, it gently transmits heat to each layerâfrom the superficial dermis down to the deep fatty tissuesâto improve overall firmness. Thermage utilizes monopolar RF to thoroughly and deeply heat the entire dermis, acting like an iron to help enhance skin tightness and reduce wrinkles. Ultherapy, on the other hand, uses focused ultrasound energy to directly target the SMAS (Superficial Musculoaponeurotic System) layerâsharpening facial contours as if focusing sunlight through a magnifying glass.

XERF is recommended for those seeking minimal pain while improving skin elasticity, pore size, fine lines, and overall texture. Ultherapy is more suitable for those who want clearer lifting resultsâsuch as a defined V-line, cheeks, or jaw contour. Thermage is most effective for those looking to simultaneously address overall skin elasticity, texture, and fine lines, or for those who wish to treat larger areas in a single session.
Procedure | Recommended For | Strengths & Indications | Main Age Group |
|---|---|---|---|
XERF | Those sensitive to pain or downtime | Simultaneous improvement of elasticity, texture, fine lines, and pores | 20s to 40s |
Ultherapy | Distinct lifting & contour definition | Lifting facial contours, skin laxity, and deeper layers | 30s to 50s |
Thermage | Comprehensive firming & fine line care | Improves wrinkles, elasticity, texture; suitable for large areas | 30s to 60s |
Each treatment should be selected based on your specific skin concerns and the results you are seeking. The wisest choice is the one that best matches your individual needs.

One of the biggest concerns with lifting procedures is their longevity and the associated pain or recovery. Please see the comparison table below.
Procedure | Energy Type | Pain Level | Return to Daily Activity | Onset of Results | Duration |
|---|---|---|---|---|---|
XERF | Dual RF | Very minimal | 0â1 day | Immediate + Gradual | Varies by individual |
Ultherapy | HIFU | Relatively high | 0â3 days | Gradual improvement after treatment | 6â12 months |
Thermage | Monopolar RF | Moderate | 0 days | Immediatelyâ1 month | 6â12 months |
XERF can be performed comfortably without surface damage, allowing many to notice improved firmness immediately post-procedure. Ultherapy delivers stronger lifting with gradual results, whereas Thermage strikes a balance between pain and recovery. Occasionally, temporary redness may occur, but this usually resolves quickly.
Q. Among XERF, Thermage, and Ultherapy, which is the least painful?
A. Thanks to dual-frequency RF and triple cooling technology, XERF typically offers much less discomfort compared to conventional energy-based lifting. Ultherapy tends to be more painful, and Thermage is moderate in this regard.
Q. Which procedure yields the fastest visible results?
A. Both Thermage and XERF usually deliver a firmer feel immediately after treatment, while Ultherapy gradually reveals contour improvements over several months.
Q. What are the main differences between XERF and the traditional Thermage/Ultherapy?
A. XERF delivers energy from shallow to deep layers in one session, offering a low-pain yet comprehensive solution for improving skin texture, pores, and facial definition.
Q. Is it necessary to undergo these treatments several times?
A. Most patients see positive improvements with a single session; however, a tailored treatment plan should be designed after thorough evaluation of each individual's needs.
At Seye clinic, we are equipped with EVE LAB and a 3D precision facial analysis system. Instead of focusing solely on shot counts, we analyze the patient's skin thickness, ligament structure, and fat distribution to specifically tailor the energy delivery plan. Ultherapy Prime procedures are administered only by certified key doctors designated by Merz, using the official product authentication system. Both Thermage and XERF are also delivered safely, based on individual facial structure and treatment goals. If sedation is needed, university hospital-level real-time monitoring ensures complete safety. Scientific diagnosis and personalized designâthese two elements set Seye clinic apart.

XERF, Ultherapy, and Thermage differ in mechanism, indications, pain level, and more. If you are looking for a solution best suited to your needs, we can provide detailed guidance from diagnosis through to treatment planning. Thank you for readingâthis has been the chief physician of Seye clinic.
