Hello, this is Dr. Won Dae-han, the director of Seongsu Primi Clinic.

　

Until now, I’ve introduced myself in many different settings as “Won Dae-han from 〇〇〇,”

　

but now that I’ve opened my own clinic, being called “Director of Primi Clinic, Won Dae-han”

　

still feels a bit unfamiliar. But I’m sure I’ll get used to it soon :)

　

I’ve built my experience in dermatology and plastic surgery clinics, focusing on laser and filler procedures,

　

and out of my passion for dermatological lasers and fillers, I’ve dedicated myself to extensive research.

　

As a result, I’ve been invited to speak at various academic conferences such as filler societies and the Rejuran Symposium,

and had the honor of teaching many fellow doctors as a guest lecturer.

　

I also authored a book summarizing my deep understanding and expertise on lasers titled,

“Understanding Dermatologic Lasers and How to Set Parameters.”
(This book is aimed at doctors, so patients might not find it very entertaining.)

I also wrote a book titled “Understanding Dermatologic Lasers and How to Set Parameters.”
(Since it’s a technical book for doctors, it might not be very fun for patients to read… haha)

　

Until now, I’ve worked as a physician at various clinics,

　

treating a wide range of cases including pigmentation, discoloration, facial asymmetry, and fat reduction,

　

accumulating extensive clinical experience across diverse areas.

　

What led me to open my own clinic

When treating pigmentation and discoloration,
I often combine various wavelengths and handpieces during procedures.

　

However, the laser machines I regularly use are extremely high-end—each costing between 100 million to 200 million KRW.

　

Because of this, it’s rare to find clinics that are fully equipped with all of these devices.
As a staff doctor, I frequently felt limited in delivering optimal pigmentation treatments.

　

Especially since it wasn’t my own clinic,
I had no choice but to follow the preset laser parameters of the institution—regardless of the outcome.

　

This made it difficult to offer truly customized, one-on-one care tailored to each patient.
(I'm sure many fellow employed physicians can relate to this frustration.)

　

On top of that, some clinics lacked skin diagnostic equipment, making accurate assessment nearly impossible.

　

There were even cases where treatment plans were misguided by misdiagnosis or aggressive sales tactics from non-medical counselors,
leading to unnecessary procedures—leaving me feeling disheartened.

　

These experiences ultimately motivated me to open my own clinic.

From the interior design to the flow of movement for both patients and staff,
to the soundproofing, heating and cooling systems, and air purification—

even down to the bedding, scents, facial cleansers, and other daily-use items—
and of course, all the medications, fillers, and laser equipment...

 

I personally selected and designed every single detail,
from the biggest decisions to the tiniest elements.

 

You might wonder, “Do you really need to go that far?”

But I genuinely put my heart into every step of the preparation.

Is it just about the interior?

 

The reason I paid such close attention to the clinic’s design is simple:
Beyond just offering great results—whether it's for clearer skin, better elasticity, scar treatment, or lifting—
I wanted the clinic to be a space of comfort.

 

In the middle of our patients' busy lives,
I hoped Primi Clinic could also serve as a peaceful, healing place to recharge—even if just a little.

All treatment rooms at Primi Clinic are private VIP suites,
and we use hotel-grade bedding for your utmost comfort.

 

We take great care with everything that touches our patients' skin,
and for those who value privacy,
everything—from anesthesia to treatment—is performed in private rooms.

We offer before-and-after comparisons for treatments

 

Dermatological procedures are not inexpensive,
so if there were no noticeable results,
even I would feel it was a waste.

 

That’s why we’ve introduced the Mark-Vu skin diagnostic system,
so we can confidently show you clear visual results—especially for pigmentation and vascular treatments.

 

Additionally, with procedures like lifting and fillers,
it is essential that before-and-after photos are taken under the same lighting,

from the same angle, and in the same position
to ensure an accurate comparison.

If the lighting or facial expressions differ, objective comparisons become impossible.

 

That’s why we use professional-grade two-point lighting,
allowing for clear and accurate before-and-after comparisons.

These are the laser devices I selected after countless hours of careful consideration.

 

As the author of a dermatology laser textbook, I have a deep passion for and understanding of laser technology.

That’s why we have no less than four different types of lasers for pigmentation and vascular treatments alone.

 

Each of these machines costs tens of millions of yen,
and while introducing them required significant deliberation,

I invested in them without hesitation for the sake of achieving the best possible results.

 

When it comes to lifting devices as well,
we only use machines that have been proven to deliver effective outcomes.

 

I've given numerous lectures on fillers over the years and have compared a wide range of products.
Each filler has its own unique characteristics — some are ideal for wrinkles, others for volume.

 

At Primi Clinic, we select different filler products for each facial area,
minimizing side effects while maximizing natural and beautiful results.

 

Since filler treatments are highly dependent on the practitioner’s skill,
I take great pride in my expertise in this area.

 

At Primi Clinic, in addition to pigmentation, vascular, and acne treatments,
filler injection is the field in which I am most confident.

I also serve as a key doctor for Rejuran's Rejuviel Filler,
and have extensive expertise in natural-looking filler design,
having trained many fellow physicians over the years.

 

With thousands of filler cases under my belt,
I have consistently pursued a natural and harmonious aesthetic,
achieving high levels of patient satisfaction without any complications or dissatisfaction.

 

This is all possible because I do not follow a one-size-fits-all, factory-like approach.

Instead, I tailor each treatment to the unique features of the patient's face,
proposing the shape that suits them best.

 

Filler procedures should not be rushed.

For beautiful and natural results, it’s essential to carefully combine both needle and cannula techniques
based on the patient’s individual facial structure.

100% Physician-Led Consultations — No Counselors

 

At Primi Clinic, we do not rely on non-medical counselors for patient consultations.

Every consultation is conducted directly by a licensed physician.

Doctors themselves understand that it is best when a physician provides the consultation directly.

 

However, many clinics still employ counselors because if a doctor handles every consultation,
they are limited in the number of patients they can see.

 

At Primi Clinic, we intentionally do not accept a large number of patients at once.

We have a strict appointment system in place, ensuring that our waiting area is never crowded.

 

For every patient who visits our dermatology clinic, we promise to:

• Keep waiting times to a minimum

• Ensure that a physician personally consults each patient

• Use a diagnostic device to deliver accurate diagnoses and compare before-and-after results

• Never recommend unnecessary procedures

• Take full responsibility for every treatment provided

 

This is the core identity upon which Primi Clinic at Seongsu was founded.

 

Furthermore, all treatment prices at Primi Clinic are clearly listed at fixed rates on our official website

We are currently running an opening event, offering our treatments at very special prices.

If you are concerned about your skin, feel free to make a reservation via Naver.

 

I will personally consult with you and provide results you can be satisfied with.

 

At Primi Clinic, we don't want to be known just for stylish interiors or high-quality materials.

What truly matters is offering only necessary and effective treatments
through accurate diagnosis—never wasting your precious time or money.

 

We promise to deliver care that is trustworthy, personalized, and results-driven
for every single person who visits us.

 

Thank you sincerely for reading this long message.

We look forward to seeing you.
