If You Are Having a GOURI Consultation in Daegu — What Miso Clinic Actually Looks At
“Which clinic in Daegu is best at GOURI?” — there is no way to answer that from public data. No metric comparing practitioners’ skill is published, reviews do not constitute evidence of effect, and a count of procedures is not the same thing as proficiency. What can be judged is something else — what the clinic asks you at the consultation, what it tells you, and what it says it will not do. This article is not promotion but a written-out procedure.
The short answer
There is no way to answer “which clinic in Daegu is best at GOURI (liquid-form polycaprolactone)?” from public data. No metric comparing practitioners’ skill is published, reviews do not constitute evidence of effect, and a count of procedures is not the same thing as proficiency. So a page that answers this question with “it is us” is itself an answer without grounds. What can be judged is something else — what a clinic asks you at the consultation, what it tells you, and what it says it will not do. For GOURI the published human data comes to 33 people in total, and it is a material that cannot be reversed with hyaluronidase. The thinner the data and the less reversible the treatment, the more the result turns on the judgement of who is a candidate, before any question of equipment or technique.
The order we actually work through in consultation
1. First we distinguish what has decreased
The first thing we do is not choose a treatment but distinguish which kind of ageing this is. The answer differs depending on whether volume has hollowed, whether the skin has thinned, or whether it has sagged. GOURI sends a signal to the dermis, so it is not an answer to change caused by lost volume. It is not uncommon for GOURI to drop out of consideration at this stage.
2. We confirm the goal as a sentence
A goal of “I want to look generally better” cannot be used to judge a result. We put into a sentence what would have to change for you to be satisfied, and we tell you on the spot whether that goal is within what GOURI can achieve. If it is outside that range, we recommend a different treatment or say that doing nothing would be better.
3. We say up front that it cannot be reversed
Polycaprolactone is not hyaluronic acid, so it does not dissolve with hyaluronidase. The literature states that this class does not respond to hyaluronidase and may require invasive removal. Irreversible does not mean permanent — it means there is no means of removing it on demand. Giving this explanation before the decision and giving it after the treatment are entirely different things.
4. We check what is already in there
If irreversible material (PCL, PLLA, CaHA) is already present in the same area, it becomes impossible to tell what caused a problem later. So we go through the treatment history area by area, and where there is overlap we defer the timing or adjust the area. We also ask about fillers, lifting and laser history.
5. We state how far the evidence goes, in numbers
| What | The actual data |
|---|---|
| Published human data | 33 people in total (30-person pilot + 2-person case series + 1 case report) |
| Longest follow-up | Six months. Beyond that it has never been measured |
| Human biopsy | We could not find a single study |
| Earliest confirmed collagen increase | Six weeks in animals (p < 0.001) |
| Nodule reports | We could not find any — but with a denominator of 33 an incidence cannot be calculated |
| The widely circulated “6–12 months” | How long the material takes to break down, not how long the effect lasts |
Some people decide against the treatment after seeing this table. We regard that as a legitimate conclusion too.
6. On sessions, we state the manufacturer’s figure first
The manufacturer’s official FAQ says “one session recommended, optionally 1–2 follow-up sessions at 4–6 week intervals.” The widely circulated “three sessions at 3–4 week intervals” is a figure for which we could not find a primary source. So we start from one session as the default and decide on anything further from the condition at four weeks or later. We also say that no trial has compared outcomes by number of sessions. The detail is in how many GOURI sessions, how far apart.
7. Where there is no data, we say there is no data
The manufacturer’s official FAQ recommends using GOURI on the face only and states that clinical data is being collected for hands and neck. The published human studies also covered the face alone, and for the neck, décolletage and back of the hands we could not find a single published study. When those areas are requested, we do not answer “yes, that is possible” — we put the alternatives that do have data alongside them first.
What we do not do
Having written out the procedure, it is only fair to write out what we do not do.
- We do not present reviews or before-and-after photographs as evidence of effect. This is prohibited in medical advertising, but before that it is because they do not hold up as evidence. How to read reviews is set out in how to read reviews.
- We do not use expressions such as “side-effect-free,” “the best,” or “the only.”
- We do not ask for a same-day decision. Bringing a decision forward with a same-day discount on an irreversible material shifts the risk onto the patient.
- We do not speak of indications without data as though data existed. We distinguish between “we could not find any,” “there is none,” and “0%.”
- We do not disparage other clinics’ treatments. Comparison is made on products and data.
Five questions you can ask at any clinic
For use when choosing a clinic, we have selected only questions whose answers settle a judgement. You are welcome to ask us as well.
- “Can this be reversed?” The accurate answer for GOURI is “it does not dissolve with hyaluronidase.” If that answer does not come straight back, there is room to check the understanding of the product.
- “How many people is the human data based on?” The published human data for liquid-form polycaprolactone comes to 33 people in total, longest follow-up six months. If the only answer is “it is a product that has completed clinical trials,” you may also ask for the paper, the abstract or the trial registration number.
- “In my case, is the problem volume or skin thickness?” If a treatment is settled on without that distinction, there is room for the direction to be wrong.
- “Why this number of sessions?” If the answer is “three,” ask on what basis. The default in the manufacturer’s official FAQ is one session.
- “Is there data for this area?” Particularly useful if you have been offered treatment on an area off the face, or on a thin area, such as the neck, the back of the hands or around the eyes.

Frequently asked questions
Which clinic in Daegu is best at GOURI?
This cannot be answered from data, because no public metric comparing practitioners’ skill exists. What can be answered is the method of judging — ask whether it can be reversed, how many people the human data covers, why that number of sessions, and whether there is data for that area, and choose the place whose answers are specific. The five questions above are set out for that purpose.
Can I just have a consultation?
Yes. There are real cases in which GOURI drops out of consideration at steps 1–2 above, and when it does we recommend a different treatment or say that doing nothing would be better.
Is a place with a higher case volume better?
We are not aware of data linking case volume to outcome. Liquid-form polycaprolactone is a product with 33 people of published human data, so it is also hard to regard a count of procedures as meaning verified experience.
What should I prepare before the consultation?
Bringing your treatment history organised by area helps most. Particularly fillers, collagen boosters and lifting, with dates. Please also tell us about medication you are taking (especially anticoagulants and immunosuppressants) and any recent vaccination or scheduled dental work.
Is it wrong to choose a clinic on price?
Price is one criterion, but with an irreversible material it is safer to place it later in the order. In particular, if a place brings a decision forward with a same-day discount, it is worth considering what that condition is standing in for.
I have already had it elsewhere — can I still be seen?
Yes. In that case which material went into which area and when is the most important information. Because layering into an area that already contains irreversible material makes the cause impossible to identify later, the consultation becomes one about adjusting timing and area.
