Yonsei Star Dermatology is a five-dermatologist practice in Sinchon, Seoul, in continuous operation since 2002. It is known nationally for scar treatment — the Pinhole technique was developed here — and runs one of the broadest anti-ageing line-ups in the city: Ultherapy Prime, Thermage FLX, and a full skin-booster range chosen for the patient rather than the product.

Anti-ageing & lifting
Ultherapy Prime for the SMAS, Thermage FLX for the dermis, dedicated eye protocols and BBL — different mechanisms at different depths, combined only where your skin needs it.

Micro-focused ultrasound to the SMAS, planned shot by shot from the patient's own facial analysis.

Monopolar radiofrequency tightening across the dermis, with vibration and cooling built into the tip.

Ultherapy and Thermage protocols dedicated to the eye area, combined with Rejuran i and hyperbaric oxygen.

Broadband light in three passes — base, pigment, skin tightening — for elasticity and tone with no downtime.
Skin boosters
Rejuran, GOURI, Re2O and Juvelook are chosen and combined according to skin thickness, hydration, texture and where the face has deflated — the clinic's Personalised Skin Booster programme.

Rejuran, GOURI, Re2O, Juvelook and others — selected and combined by zone from the skin in front of the doctor, not by product.

Polynucleotide skin booster for barrier recovery and texture; Rejuran i for the eye area.

Liquid-form polycaprolactone collagen stimulator — particle-free, spread across the field, lasting six months or more.

PDLLA microspheres with hyaluronic acid for skin density, fine texture and pores; Juvelook Volume for deflated areas.
Why this clinic
Since 2002 the clinic has studied how skin changes and how it recovers. Rather than following fashionable procedures, it works from an understanding of the skin's structure and from long clinical experience. From anti-ageing to the hardest scar revisions, the field may differ but the principle is the same: understand the skin deeply, make a real difference in the treatment, and deliver value beyond expectation.

Ultherapy Prime, Thermage FLX and laser shockwave for lifting; Rejuran, GOURI, Re2O, Juvelook and a custom booster programme for skin quality. Different mechanisms, different depths — chosen per face.
Led by Dr. Lee Sang-joo, current President of the Korean Dermatologists Association, every physician at the clinic is a dermatology specialist with substantial clinical experience.
The clinic focuses on structurally complex scars and on patients who were treated elsewhere without enough improvement. The Pinhole technique was developed here; Pinhole, laser subcision and multiple laser platforms are combined according to the scar rather than repeated by rote.
Our doctors
Every consultation and every treatment is by a dermatology specialist. Dr. Lee Sang-joo, Representative Director, is the current President of the Korean Dermatologists Association.
Scar treatment
The Pinhole technique was developed here. Burn, surgical, self-harm, acne and keloid scars — including cases treated elsewhere first — are planned from the scar's structure, not its name. Scar programmes run over months and are scheduled around your travel.

The clinic's own method for burn, surgical and self-harm scars: dense laser micro-perforation through matted collagen, regenerating the scar layer by layer.

Subcision, matched laser, regenerative injection and laser shockwave in two alternating stages for depressed acne scars.

Ultra excision with steroid injection for keloids — including the earlobe — followed by a scheduled maintenance course.

Eyelid, epicanthoplasty, rhinoplasty and other post-surgical scars treated with Ultra laser and laser subcision.

How a visit works
Every patient is seen by one of five board-certified dermatologists, not by a consultant. The plan is written by the physician who will treat you.
Skin thickness, elasticity, hydration, texture, pigment depth or scar structure are examined before any device is chosen.
Treatments with different mechanisms and depths are combined where the skin needs it — and withheld where it does not.
Progress is reviewed at set intervals. Courses are adjusted against what the skin actually did, not against a package.
FAQ
Consultation is with a board-certified dermatologist. Message us on WhatsApp in English with what you want to change and how long you will be in Seoul; an interpreter is arranged when needed.
