Gouri: Liquid, So It Spreads
Polycaprolactone with no microspheres in it. Because it is fully liquid, it spreads through the tissue instead of staying where the needle went — which is why it builds collagen rather than filling a line.

Quick Answer
What is Gouri?
It replaces the collagen you have lost, not the volume.
In Brief
Fully liquid PCL. A stimulator, not a filler.
Gouri is polycaprolactone — a biodegradable polymer long used in medicine — in a fully solubilised form. Earlier PCL products were suspensions of microspheres, which stay where they are placed and act as fillers. Gouri has no particles in it at all, so it disperses through the dermis and works as a scaffold that provokes your fibroblasts into producing collagen. The polymer then breaks down, and what remains is collagen you made yourself. It is made by Dexlevo in Korea and holds CE approval.

Understanding It
Why Liquid Changes What It Does

“A filler sits where you put it. This spreads out and wakes the tissue up.”
Polycaprolactone is not new. It has been used in sutures and implants for years, and as an aesthetic injectable it usually arrives as microspheres suspended in a gel. Those particles stay roughly where they are placed, which makes them useful for adding volume to a specific spot — and means they behave like a filler, with a filler’s risks of lumps and overcorrection.
Gouri is the same polymer dissolved rather than suspended. With nothing particulate in it, it spreads through the dermis as a thin, even layer. That changes the job entirely: instead of occupying space, it gives fibroblasts a surface to work against across a whole region. Collagen production rises where it spreads, the polymer biodegrades, and the improvement you are left with is your own tissue.
A Fair Question
“If it is not a filler, what will I actually see?”
Not volume. Gouri does not plump a hollow or lift a fold, and if that is what you want, a filler is the honest answer and we will say so. What changes is the quality of the skin itself — firmness, fineness of texture, the way light sits on it, and fine lines that soften because the skin beneath them has thickened. People most often notice it around the eyes and across the lower face. It is a gradual change that others register before they can name it.
How It Works
Spread. Stimulate. Dissolve.
A scaffold that does its work, then leaves.
01
First, whether collagen is the actual shortfall
Lost firmness can come from thinning collagen, from lost volume, or from laxity that no injectable will reach. Your doctor works out which before anything is planned. If the issue is volume or sagging, Gouri is the wrong tool and we will tell you so.

02
Then, a few points and a wide spread
A full face takes around ten injection points, five a side, because the liquid travels from each one rather than staying put. The periorbital area takes two. The session itself runs 20 to 30 minutes.

03
Then your collagen builds, and the polymer goes
Fibroblasts respond to the scaffold and lay down new collagen around it. Early change shows from about two to three weeks, and the polymer biodegrades over the months that follow. Results generally hold 6 to 12 months before a maintenance session.

Candidacy
Who It May Be For
— Your skin has lost its fineness and firmness, though nothing has sagged yet.
— Fine lines bother you more than folds, particularly around the eyes.
— You want skin quality improved without anything being added to your face.
— You’re willing to wait a few weeks and come back two or three times.

Side by Side
How the Collagen Treatments Differ
Several products claim to build collagen. They do it by different routes, and the route decides who each one suits.
| Gouri | Juvelook | Radiesse | Tissivo | Rejuran | |
|---|---|---|---|---|---|
| Material | Liquid PCL | PDLLA | Calcium hydroxylapatite | Human dermal matrix | Polynucleotide |
| Form | Fully liquid, no particles | Microparticle suspension | Microsphere gel | Micronised matrix | Solution |
| How it acts | Spreads, then stimulates | Stays, then stimulates | Adds volume and stimulates | Supplies matrix | Signals repair |
| Adds volume | No | Slightly | Yes | No | No |
| Course | 2 to 3, about 4 weeks apart | Usually a short series | Usually one | Set in consultation | Usually a short series |
| Best when | Skin quality and fine lines | Collagen and firmness | Volume and firmness together | Skin has thinned | Repair and texture |
More than one of these may suit you, and a plan often sequences them. Which is right depends on where the change actually sits, and that is settled by examination.
On the Day
What Actually Happens
Four steps, and the appointment is shorter than most people expect.
01
Consultation before anything is drawn up
Your skin is examined and the shortfall identified. If what you want back is volume rather than quality, we will say so before anything is planned.
02
Cleansing, then numbing cream
The area is cleansed and numbing cream applied, then left to take effect.
03
The injection itself
Around ten injection points across a full face, five a side, or two for the eye area. The liquid spreads from each point rather than staying where it went in.
04
Pressure, then aftercare
The sites are compressed and dressed. Downtime is minimal. Change begins showing from two to three weeks and builds across the course.
Key Points
What to Take Away
- Fully solubilised polycaprolactone — no microspheres, so it spreads rather than sitting where it is placed.
- A collagen stimulator, not a filler. It will not add volume or lift a fold.
- About 10 injection points for a full face, 2 for the eye area. Twenty to thirty minutes.
- Course of 2 to 3 sessions, roughly 4 weeks apart.
- Change shows from 2 to 3 weeks and generally holds 6 to 12 months.
- Maintenance once or twice a year.
- Made by Dexlevo in Korea, CE approved.
- Wrong answer for sagging. That needs lifting, not collagen.
FAQ
Questions People Ask
No, and the distinction matters. A filler occupies space where it is injected and gives you volume straight away. Gouri is fully liquid, so it spreads through the dermis instead of staying put, and what it does there is provoke your fibroblasts into making collagen. You will not see volume added. You will see the skin itself change over the following weeks.
Older PCL injectables are suspensions of solid microspheres in a gel. Those particles stay roughly where they are placed, which makes them behave as fillers and carries the risk of nodules or overcorrection. Gouri is the same polymer dissolved rather than suspended, so there is nothing particulate in it. That is what lets it spread, and it is also why it can be used in thin skin such as the eye area, where microsphere products are riskier.
Usually two to three sessions about four weeks apart, then maintenance once or twice a year. Older skin, with less collagen-making capacity to draw on, tends to need the full three. Your doctor will tell you which after examining your skin rather than before.
Early change from around two to three weeks, building across the course as collagen accumulates. Results generally hold somewhere between six and twelve months, which varies with age, skin condition and lifestyle more than most clinics admit.
It is used across the full face for overall skin quality, and it suits the periorbital area — crow’s feet and the thin skin of the eyelid — better than particle-based products can. It also softens nasolabial folds and horizontal forehead lines, though by improving the skin rather than filling the crease.
Polycaprolactone, a biodegradable polyester that has been used in medicine for years in sutures and implants. Gouri is made by Dexlevo in Korea and holds CE approval. Ask to see the syringe and its labelling before treatment — we would rather you did.
