Eye XERF is the eye-area option of XERF, a dual-frequency radiofrequency (RF) skin-tightening treatment. At COCO Clinic in Seoul it is a separate 300-shot protocol that delivers lower energy through a dedicated tip for the thin skin around the eyes, aimed at fine lines and firmness. It costs ₩850,000 including VAT, is often combined with a full-face XERF session, and the change builds over about 2–3 months. Lines that appear mainly when you smile or squint are expression lines, which wrinkle Botox treats, so the eye area is assessed in person first.
Short Answer: What Eye XERF Does and Who It Suits
Eye XERF works on the skin around the eyes: fine lines and loss of firmness in thin, slackening skin. It is one option for that concern, not the only one, and whether it fits is decided in person, after checking whether the lines come from the skin itself or from muscle movement. COCO Clinic was designated an official XERF Heavy User by the manufacturer in February 2026, on the basis of more than 30 cases a month through 2025.
What Eye XERF Is and How It Differs From a Full-Face Session
XERF is a monopolar radiofrequency (RF) device made by Cynosure Lutronic. Its two frequencies, 6.78 MHz and 2 MHz, heat the dermis and the layer beneath it while the surface is protected: existing collagen tightens slightly straight away, and new collagen builds over the following 2–3 months.
Eye XERF is a separate protocol within that menu. At COCO Clinic it is a 300-shot session for the area around the eyes only, using a dedicated tip and lower energy suited to the thin, sensitive skin there. It targets fine lines and firmness around the eyes, and it is often combined with a full-face XERF session — whether to combine is decided in person.
Who May Be a Candidate for Eye XERF, and Who Should Wait
Eye XERF suits fine lines and loss of firmness that come from the skin around the eyes itself. Lines that show mainly when you smile or squint are expression lines driven by muscle, which wrinkle Botox treats, so the two are told apart in person — and sometimes combined. For how XERF works on the rest of the face, see How XERF Radiofrequency Lifting Works.
Tell the clinic beforehand if any of these apply:
- A pacemaker or other implanted electronic or metal medical device — RF is not done
- Pregnancy
- Inflammation or infection around the eyes
If you have had other treatments recently, the spacing is short. Filler placed within the last two weeks: COCO Clinic would rather wait until two weeks have passed, though it can go ahead if today is your only day. Botox in the last few days: about two weeks before lifting when possible. Threads already in place do not get in the way. If filler, a booster or Botox is planned for the same day, the lifting is done first; on a separate day, injections come a week after the lifting.
At COCO Clinic, a professional consultant provides a detailed one-on-one consultation. The doctor may also conduct a brief assessment before the procedure. This is where candidacy questions and your treatment history are reviewed.
Session Planning and Published Pricing
COCO Clinic's published XERF prices, all VAT included, are shown below with the clinic's stated use for each option, as listed on its XERF page.
| Option | Published price (KRW, VAT included) | Use |
|---|---|---|
| 300 shots | ₩950,000 | Small area, maintenance |
| 600 shots | ₩1,800,000 | Standard · recommended |
| 900 shots | ₩2,600,000 | Forehead to neck, full tightening |
| Eye (300 shots) | ₩850,000 | Around the eyes only · fine lines, firmness |
The shot count is chosen at the consultation by age, laxity and area; the 900-shot option can vary with the area covered, and the final cost is confirmed then.
As with XERF elsewhere on the face, the change builds over about 2–3 months, so for an important date one to two months ahead is the usual reference point. How often to repeat Eye XERF is decided individually.
Pain, Downtime and Side Effects
- Pain: a warm to hot sensation, kept comfortable with cooling and output control. Numbing is usually not needed, though numbing cream is available if you are sensitive.
- Downtime: virtually none. Slight redness right after usually settles within the day, and daily life and make-up can continue the same day.
- Common, settling in hours to days: temporary redness, warmth, mild swelling.
- Occasional: tenderness at the treated area, fine marks.
- Rare: burns or blisters — possible with excessive output, and prevented by adjusting output and cooling.
If redness or pain lasts more than a few days, or a blister forms, contact the clinic. Results vary between individuals, and no outcome can be promised.
How to Choose a Clinic for Eye-Area Tightening in Seoul
Whichever clinic you consider, these questions are worth asking:
- Who performs the treatment, and what is their experience?
- Is pricing itemised, with VAT stated?
- How are contraindications and recent treatments screened?
- How does the first visit work, and how is follow-up handled?
At COCO Clinic, the medical director is Dr. Jay, with 10+ years in skin anti-aging and face lifting; prices are published with VAT included; and a professional consultant leads the one-on-one consultation, with a brief doctor assessment before treatment.
Planning a Visit From Abroad
COCO Clinic is in Seoul. Eye XERF itself fits a short trip: there is virtually no downtime, so you can go back to your day straight away. The change builds over 2–3 months, so you will most likely be home before you see the full result.
Before booking, share your recent treatment history — especially filler or Botox in the last two weeks — and ask whether the consultation and treatment can happen on the same visit.
Readers who want to discuss candidacy can contact COCO Clinic through the contact methods listed on its English website.
Results vary between individuals.
Frequently Asked Questions
What is Eye XERF?
The eye-area option of XERF, a monopolar radiofrequency treatment that uses 6.78 MHz and 2 MHz together. At COCO Clinic it is a separate 300-shot protocol with a dedicated tip and lower energy for the thin skin around the eyes.
How much does Eye XERF cost at COCO Clinic?
₩850,000 including VAT for the 300-shot eye session. It is often combined with a full-face XERF session, and the final cost is confirmed in person.
Who should not have XERF treatment?
RF is not done with a pacemaker or other implanted electronic or metal medical device, during pregnancy, or with inflammation or infection at the treatment site. If filler went in within the last two weeks, or Botox in the last few days, COCO Clinic would rather leave about two weeks first; threads already in place do not get in the way.
Will Eye XERF remove fine lines around the eyes?
No outcome can be promised. Eye XERF works on fine lines and firmness that come from the skin itself, and the change builds over about 2–3 months. Lines that appear mainly when you smile or squint come from muscle movement, which wrinkle Botox treats.
Does Eye XERF hurt, and is there downtime?
It feels warm to hot, kept comfortable with cooling and output control, and numbing is usually not needed. Downtime is virtually none: slight redness usually settles within the day, and make-up is fine the same day.
When should I plan treatment before an important event?
One to two months ahead is the usual reference point for lifting, because the change builds while new collagen forms. Ask how that applies to your eye area and plan.
