We look for ways to improve results while reducing side effects.
Our aim is a longer-lasting contour, not a one-time change.

LINE ON Injection
A course of injections that slims the area a little at a time. For when surgery feels like too much and only one spot bothers you.
II
Mini LINE ON Lipo
One area that bothers you, removed in a single session. For when a long recovery isn’t possible but you want a clear change.
III
LINE ON Lipo
As much as your frame allows, in one surgery. We only go as far as the risk of side effects stays low.
Treatments
For each treatment, Dr. Oh explains who it may suit, who it may not, and how long recovery takes.

Face line on
Rather than filling one area at a time, we restore balance across the whole face.
A face is about harmony, not close-ups. The goal is a face that looks more alive, not a bigger one, so for most people 3 mL is enough.Dr. Oh Hae Seok, Medical Director

Nose line on
Non-surgical nose shaping for a nose that’s already good but could be a little more defined. We build support with 4–6 LSCO threads and use only as much filler as needed.
Just as a building needs both steel and concrete, I use threads to build the structure and filler to refine the shape.Dr. Oh Hae Seok, Medical Director

Breast fat transfer
Add one to one and a half cup sizes with your own fat, no implants.
Body weight matters most for how much fat stays. At the very least, please try not to lose weight.Dr. Oh Hae Seok, Medical Director

Waist, hip & thigh
We don’t look at the thighs or the waist alone, but at the whole line from your waist down to your thighs.
If you only treat the thighs, only the thighs improve. What matters is the line that runs from the waist through the buttocks to the thighs.Dr. Oh Hae Seok, Medical Director
Process
01
We start with what you’d like and what’s holding you back.
02
An exam and ultrasound show what to remove and what to keep.
03
We tell you the expected change and its limits up front.
04
After the stitches are out, we check in at 1, 2 and 3 months.
Our promise
Before asking whether we can, we ask whether it will truly help you.
Sometimes a patient who is already slim says, “If I could just lose a little more, it would be fine.”
Removing more at that point doesn’t make the contour smoother. Instead, the outline of bone and muscle can show too much, and the shape can look uneven. A good contour needs some fat to stay.
Breast fat transfer isn’t decided by looking at the breasts alone.
The fat has to come from your own body, so we first look at how much can reasonably be harvested, not only how much you’d like to add. Pushing ahead anyway means harvesting from more areas without getting the change you hoped for. In that case, we’ll tell you, “We could try, but we don’t recommend it.”
Together, we first work out exactly what you like in the photo.
Is it a defined waist, a smooth side profile or a short, soft jawline? Once we know, we talk about how to create that feature with what you have now. Even when two waists look alike, rib cage size and pelvic width don’t change easily.
Before anything else, we explain what is possible and where the limits are.
Talking only about what’s possible makes for an easy consultation, but you may be disappointed when you see the result later. Once you’ve heard everything, we respect your decision. But we won’t do anything that could harm your body.
Published studies put the fat retention rate for breast fat transfer at around 50%.
It can fall as low as 30% if you lose weight and rise as high as 70% if you gain weight. A number without its conditions means little. Eating well, sleeping well and keeping your weight from dropping are part of the treatment.
If you don’t exercise enough and keep overeating after treatment, the results will fade.
This is true of everything from injection treatments to Mini LINE ON Lipo and liposuction. That’s why we’re open at your consultation about what it takes to maintain results. What matters is a healthy contour that lasts.

Research & invention
Looking for ways to improve results while reducing side effects led to patents,
and one of them became a product now used by physicians in other countries.
On the 61st Invention Day in 2026, Dr. Oh received a commendation from the Minister of Intellectual Property.
5 key inventions, 13 registered patents

In production, exported to 4 countries, 6 registered patents
The thread anchors at two points, the nasal bridge and the columella (the column of skin between the nostrils), and its folded L-shaped end fills and supports the nasal tip directly. A folded surface, rather than the sharp end of a straight thread, sits against the tissue. The aim of this design is to lower the risk of the thread pushing through the skin.
Absorbable PDO (polydioxanone); 19G, 45 mm half-L cannula; 3 depth-guide markers; bridge 42 mm, columella 20 mm, tip 2 mm
Clinical evaluation plan: 40 patients, 4 threads each; before, right after and at 3 months; nasal tip projection ratio, nasolabial angle and GAIS; thread position checked by ultrasound
Korean Patent Nos. 10-2358717, 10-2411627, 10-2411628, 10-2411629, 10-2411630 and 10-2461560 (lifting thread for nose shaping; lifting thread)

4 registered patents, physical prototype built, co-development under discussion with a global company
A soft feel, and the strength to hold its shape without wrinkling (rippling): for a long time, implants have had to give up one of these qualities to gain the other. This implant is designed with a double membrane, an extra layer around the implant, to offer both.
The physical prototype was made with standard implant manufacturing processes, without new materials. We expect it to be most relevant to breast reconstruction, where the covering tissue is thin, and plan to refine it with a company experienced in manufacturing and regulatory approval. This implant is not used at LINE ON Clinic.
In finite element analysis (FEA), with the implant tilted to 90°, surface indentation was about 5 mm less than in a single-membrane model (10.5 mm vs. 16 mm), and peak stress was also lower (0.095 vs. 0.123 MPa)
Korean Patent Nos. 10-2826523, 10-2845331, 10-2877058 and 10-2952197 (breast implant; manufacturing method; implant cover)
Registered patent, preparing for production
Designed to reduce the bluish tint that filler can show under thin skin, such as under the eyes or along the nasal bridge.
Korean Patent No. 10-2877057 (skin filler composition)
Patent pending
Designed so that the parts of the thread that lift tissue and the parts that anchor it sit in effective positions.
Korean patent applications 10-2026-0084067 and 10-2026-0112236 (cannula for thread lifts)
2 registered patents, comparative study designed
A needle with separate channels (Separate Lumen System): one for the filler and one for checking blood backflow, to help prevent filler from entering a blood vessel. It is designed so that backflow can be noticed right away if the needle enters a vessel. It is not yet used in treatment.
27G + 34G dual lumen. Study design: blood detection rate and time to detection compared with standard 25G and 27G needles in an animal model (Doppler ultrasound guided)
Korean Patent Nos. 10-2405915 and 10-2125976 (needle for backflow detection; syringe for filler)
