Hello, this is the director of ORTA Clinic.

One of the questions we hear most often in lifting consultations these days is, "How is XERF different from Thermage?" Since XERF is a relatively new device, there isn't much information available yet, and many patients are curious. Today, I'll walk you through how XERF works, who it's a good fit for, and the principles we follow at ORTA Clinic when designing each treatment.

What is XERF?

XERF is a non-invasive, monopolar radiofrequency (RF) lifting device that combines two frequencies — 6.78MHz and 2MHz — to deliver energy at different depths of the skin. By raising the temperature within the skin, it induces immediate collagen contraction, followed by collagen remodeling over the next one to three months, which can improve skin elasticity and sagging. It is a medical device approved by Korea's Ministry of Food and Drug Safety (MFDS).

XERF belongs to the same family as existing monopolar RF devices (such as Thermage), but its defining feature is the dual-frequency system, which allows the energy delivery depth to be adjusted across three levels: Shallow, Middle, and Deep.

How XERF Works

Dual-frequency depth control — Energy is delivered shallowly in areas where the skin is thin, and deeper in areas with more pronounced sagging, such as the cheeks and jawline.
Impedance feedback — The device measures each person's unique skin resistance in real time and adjusts the energy accordingly.
Real-time temperature monitoring + 3-stage cooling — Skin surface temperature is monitored and cooled throughout the treatment, reducing heat-related discomfort and irritation to the epidermis.
Immediate contraction + long-term remodeling — Right after treatment, collagen contraction produces a tightening effect; over the following one to three months, collagen regeneration gradually improves elasticity.

What Results Can You Expect from XERF?

Results and their duration may vary from person to person depending on skin condition.

Tightening of sagging cheeks and mid-cheek fullness
A more defined jawline and improvement in the double-chin area
Softening of fine lines around the eyes, mouth, and forehead
Improved overall skin elasticity
Improvement in skin texture and pores
Gradual lifting effect through collagen remodeling (progressing over roughly 1–3 months)

Who Is XERF Recommended For?

Those interested in RF lifting but concerned about pain
Those beginning to notice sagging in the cheeks or jawline who want to manage elasticity without surgery
Those who need to return to daily life immediately (washing your face and wearing makeup the same day)
Those concerned about both fine lines and loss of skin elasticity
Those who want regular skin elasticity care at 6-month to 1-year intervals

How XERF Is Performed at ORTA Clinic

Even with the same device, satisfaction with the results depends on who designs the treatment and by what standards. At ORTA Clinic, we follow these principles.

We diagnose and design for each individual patient. After assessing skin thickness, elasticity, and the location and depth of sagging, we plan the energy intensity and shot distribution differently for each area.
Depth-customized design by area. Thin-skinned areas such as the forehead and around the eyes are treated in shallow mode, while areas with deeper sagging, such as the cheeks and jawline, are treated in deep mode.
A 1:1 customized plan combining our devices. We also offer devices that work at different layers of the skin — including Ulthera (ultrasound), Onda, and Rejuran — so rather than pushing a single treatment, we recommend the combination best suited to your condition.
Authentic tips and the exact number of shots promised. We show you the authentic tip before treatment and deliver exactly the number of shots discussed.
Pain management protocol. Three-stage cooling comes standard, and for those sensitive to pain, we adjust comfort measures together during the pre-treatment consultation.

Aftercare Instructions

On the day of treatment, avoid saunas, hot baths, and strenuous exercise.
Temporary redness, warmth, or swelling may occur in the treated area and usually subsides within hours to a few days.
Apply sunscreen diligently for 1–2 weeks after treatment.
Avoid harsh scrubs, peels, and other abrasive skincare for about a week.
If symptoms persist, or if you experience blistering or significant pain, please contact the clinic.

Possible side effects: As with any medical procedure, XERF may cause temporary redness, swelling, or a sensation of heat, and in rare cases burns or pigmentation, depending on the individual. Please consult thoroughly with your medical provider before treatment.

Frequently Asked Questions (FAQ)

Q. How many XERF sessions do I need?

A. Visible change can be expected from a single session, and results last about one year (individual variation). Depending on the degree of elasticity loss, we recommend regular sessions every 6 months to 1 year.

Q. When will I see results?

A. Tightening from collagen contraction appears immediately after treatment, while the main improvement in elasticity develops gradually over 1–3 months as collagen remodeling progresses.

Q. Should I choose Thermage or XERF?

A. Both are monopolar RF devices that act on collagen in the dermis. XERF's distinguishing features are its dual-frequency system with three adjustable depth levels and its three-stage cooling. The right device differs depending on skin thickness, where the sagging is, and pain sensitivity, so we recommend deciding after a diagnosis.

Q. Does the treatment hurt?

A. With its three-stage cooling system and real-time temperature monitoring, XERF is generally performed without separate anesthesia, feeling like gentle warmth. Pain perception varies by individual, however — if you are sensitive, let us know before treatment and we will adjust accordingly.

Q. Can I wash my face or wear makeup the same day?

A. Yes. As a non-invasive treatment, both washing your face and wearing makeup are fine the same day. Just avoid hot saunas and strenuous exercise on the day of treatment.

If you have more questions about XERF or would like to find out whether it suits your skin, please feel free to contact ORTA Clinic in Seocho, Seoul. Through a consultation, we will work with you to determine the right care plan for your skin's current condition.
