Leading treatments
Rhinoplasty
Rhinoplasty reshapes the nose. The clinic's main nose operation is a structure-first rhinoplasty it calls ONYX Core, which uses the patient's own cartilage. The clinic's English website says anesthesia is sedation or general, the operation takes about 1.5–3 hours, and the splint and stitches come out after about 5–7 days. It suggests about 7–10 days in Korea, because most patients fly home after a check at one week, and says you can ask the team questions on WhatsApp after you return. The clinic says Dr. Yoo personally consults, designs and performs every operation. No regular price is published: the official website says the cost depends on the case and gives an estimated range after reviewing your photos.
Revision rhinoplasty
Revision rhinoplasty corrects the result of an earlier nose operation. The clinic offers revision surgery, including correction of a contracted nose and reconstruction with rib cartilage. Its English website says revision is done under general anesthesia and takes about 2.5–4 hours (about 3–4 hours for a contracted nose), that the splint and stitches come out after about 7 days, and that a revision is usually considered 6–12 months after the last operation. It suggests about 10–14 days in Korea. No regular price is published.
Septoplasty
Septoplasty straightens a deviated septum, the wall inside the nose. The clinic also offers functional rhinoplasty for breathing, alone or together with a cosmetic rhinoplasty. Its English website says septoplasty is done under general anesthesia, takes about 1 hour on its own and 1–2 hours for deviated septum surgery (longer when combined with rhinoplasty), uses internal splints for about 5–7 days and needs about 7 days in Korea. The clinic's Korean website lists functional rhinoplasty as an add-on at an event price with no end date, which is not shown on this page.
Double eyelid surgery
Double eyelid surgery creates a crease in the upper eyelid. The clinic's Korean website lists non-incisional and incisional double eyelid surgery, ptosis correction, eye-corner surgery (epicanthoplasty and lateral canthoplasty) and lower blepharoplasty. The official English website does not mention eye surgery. No prices or procedure details are published.
Fat transfer
Fat transfer moves a patient's own fat to another area. The clinic's Korean website lists facial fat grafting. Its only dated price is a KakaoTalk channel-friends offer: ₩490,000 for one area excluding the forehead, first session, VAT excluded, for surgery by 31 October 2026. If existing filler must be removed first, the Kakao Map notice adds ₩100,000 for a filler-dissolving injection. No regular price is published.
Liposuction (double chin)
The clinic's Korean website lists double-chin liposuction, double-chin muscle tightening and facial liposuction. The KakaoTalk channel-friends offer for double-chin liposuction with muscle tightening is ₩1,190,000, VAT excluded, for surgery by 31 October 2026. The Korean website shows a different event price with no end date and VAT included, which is not shown here, so ask which price applies to you.
Thread lift
A thread lift places threads under the skin to lift the tissue. The clinic's Korean website names VXIL, MINT, VOV, EPITICON, Silhouette Soft and Elasticum threads. The KakaoTalk channel-friends offer is ₩590,000 per session, VAT excluded, until 31 October 2026; the Kakao Map notice does not state the thread type or the number of threads.

ONYX Plastic Surgery publishes no regular price list. Its official English website says the cost depends on the case and gives an estimated range only after the clinic reviews your photos, and HIRA holds no non-insured fee data for the clinic, which registered in 2026. The clinic's Korean website posts event prices for first rhinoplasty, revision rhinoplasty, functional rhinoplasty and double-chin surgery with no end date; they cannot be dated, so this page does not show them. The only dated prices are the clinic's offers for KakaoTalk channel friends in a Kakao Map notice posted on 3 September 2026. They are for people who have added the clinic's KakaoTalk channel, run until 31 October 2026 (surgery counted by the date of the operation) and exclude VAT, which is added at payment. The notice does not say whether international visitors can use them. Ask the clinic for a written estimate in KRW that states whether VAT is included. Approximate US dollar amounts use the exchange rate of 23 October 2026.

Doctors
Yoo KunwoonRepresentative director (대표원장), medical director and plastic surgeon
Korea's HIRA registry (Health Insurance Review and Assessment Service) lists 1 doctor at ONYX Plastic Surgery, a plastic surgery specialist (October 2026), and 1 operating room. Plastic surgery (성형외과) is the clinic's only registered department. HIRA does not publish names. The clinic names one surgeon:
- Dr. Yoo Kunwoon (유건운), representative director and plastic surgeon, board-certified plastic surgeon: the clinic's only registered doctor, matching HIRA's one specialist. The clinic says Dr. Yoo personally consults, designs and performs every operation, and consults in English. It lists membership of the Korean Society of Plastic and Reconstructive Surgeons, the Korean Association of Plastic Surgeons and the Korean Society for Aesthetic Plastic Surgery.
The clinic's Korean website also says an anesthesiologist is present during surgery. HIRA lists no anesthesiologist at the clinic, so ask who will give your anesthesia and whether that doctor is present for your operation.

How many days do I need in Seoul for rhinoplasty at ONYX?
The clinic suggests about 7–10 days for a first rhinoplasty, 10–14 days for revision rhinoplasty and about 7 days for septoplasty. It says the splint and stitches come out after about 5–7 days and that most patients fly home after a check at one week. These are the clinic's typical figures, not a promise for your case.
Is the surgeon at ONYX Plastic Surgery board certified?
HIRA lists 1 doctor at the clinic in October 2026, a plastic surgery specialist, so Dr. Yoo Kunwoon, the clinic's only registered doctor, is a board-certified plastic surgeon. HIRA lists 1 operating room and 3 recovery beds at the clinic. The clinic opened in June 2026, as its HIRA registration date of 24 June 2026 shows.
Who gives the anesthesia at ONYX Plastic Surgery?
The clinic's Korean website says an anesthesiologist is present during surgery, while its English website says anesthesia is sedation or general, depending on the operation. HIRA lists no anesthesiologist at the clinic (October 2026). Ask who will give your anesthesia and whether that doctor is registered at the clinic.
Is ONYX Plastic Surgery open on Thursdays?
Yes. The clinic's Korean website and Naver Map give Monday to Friday 10:00–19:00, Thursday included, and Saturday 10:00–16:00, with Sundays and public holidays closed. Naver Map gives last reception at 18:30 on weekdays and 15:30 on Saturday. Kakao Map still shows other hours (from 09:30, closed Thursdays); the clinic's own sources do not support them. Book ahead on WhatsApp or by phone.
Can tourists still get a VAT refund on surgery in Korea?
No. The tourist VAT refund on cosmetic procedures ended on 31 December 2025, so surgery at ONYX Plastic Surgery is not tax-free for tourists. The clinic makes no tax-refund offer. Its KakaoTalk channel-friends offers exclude VAT, so 10% VAT is added to those prices and cannot be reclaimed at the airport.
