Gouri: a liquid PCL collagen biostimulator
Gouri is an injectable collagen biostimulator from Dexlevo, a South Korean company, whose active ingredient is polycaprolactone (PCL) in a low-viscosity liquid form. Dexlevo describes it as the first liquid polymer filler. It is supplied as a prefilled syringe and administered at a small number of points on each side of the face.
PCL is a biodegradable polymer used in several collagen-stimulating injectables. Unlike a hyaluronic acid filler, it is not intended to add immediate volume. It is placed in the tissue and is described as forming a framework that prompts the body to produce new collagen over the following weeks and months.
Gouri is aimed at practitioners who want a biostimulator for skin quality and firmness, rather than a filler for volume or fold correction. Results develop gradually and no independent clinical trials of this product were found, so patients should be given a realistic timeline.
Polycaprolactone in a low-viscosity form that is injected through a fine needle and spreads in the tissue.
Described as forming a scaffold that supports the body's own collagen production over weeks to months.
The listed technique uses five points per side, which keeps sessions short.
It does not give immediate volume and should not be offered as a fold or volume correction.
Why practitioners stock Gouri
A five-points-per-side technique makes the procedure simple to teach and to standardise across a clinic.
The low-viscosity liquid is described as easy to administer and quick to spread under the skin.
For patients who want a collagen-stimulating approach instead of a hydrating one, or who have had HA-based treatments already.
Tiered pricing applies from 5 units for clinics that stock several syringes.
Treatment areas and indications
Areas and concerns where liquid PCL biostimulators are used. All are skin-quality indications. The product does not replace volume.
Early loss of skin firmness and suppleness on the cheeks and lateral face, treated using the five-point-per-side pattern.
Patients who prefer a biostimulator to a hydrating booster, or who want a longer-term approach.
Used alongside toxin, skin boosters or fillers, with each product addressing a different contributor to ageing.
Gouri is an injectable medical product. Which indications are permitted and what training is required are set by the regulatory framework where you practise. Korea Filler Experts supplies the product. Nothing here is a recommendation to treat any medical condition, and nothing here replaces manufacturer training.

What each component does
Polycaprolactone (PCL)
PCL is a biodegradable synthetic polymer that the body breaks down gradually. It is used in several collagen-stimulating injectables. Distributor materials describe Gouri as a liquid PCL that spreads through the tissue and forms a three-dimensional framework on which new collagen is laid down.
The PCL concentration, carrier and syringe volume are not stated in the information we hold. Check the carton for the definitive composition.
Gouri compared with a skin booster and a filler
- A hyaluronic acid skin booster hydrates the dermis. Its effect begins soon after injection and fades as the HA is cleared.
- A hyaluronic acid filler gives immediate volume and structure.
- A PCL biostimulator such as Gouri does not add volume at injection. It is intended to prompt collagen over weeks and months, and the effect is described as lasting longer than HA. We are not aware of independent data on the duration for this product.
Regulatory status
PCL is used in several collagen stimulators sold in different markets, but this does not mean that Gouri itself holds approval in your country. We do not hold FDA documentation for Gouri. Confirm its status where you practise before you buy.
How Gouri is used
Reference information for trained practitioners. Collagen biostimulators have specific technique and complication-management requirements. Manufacturer training and the instructions for use take precedence over this page.
Step by step
-
Assess and consent
Confirm the aim is skin quality and firmness, not volume or fold correction. Review medical history, medication, autoimmune disease, scarring tendency and previous fillers. Explain that results develop over weeks to months.
-
Apply topical anaesthesia
A numbing cream is applied before the procedure, as described in the listing information.
-
Prepare and mark
Cleanse the skin, remove make-up and mark the five points on each side of the face according to your training.
-
Inject at the marked points
Place the product at each point using the technique and depth in the instructions for use. Inject slowly, and aspirate or use a cannula as your training specifies.
-
Do not over-correct
A biostimulator is not a filler. Do not add extra product to achieve an immediate visible change.
-
Follow up
Review at the interval your protocol sets and assess the response before any repeat treatment. Do not repeat early.
Administration notes
Patients should not expect an immediate result. A biostimulator works over weeks to months. If the patient wants an instant visible change, a hyaluronic acid filler is the appropriate tool.
Avoid sensitive sites unless trained. Placement around the eyes, eyebrows and mouth is technically demanding and carries a higher risk of lumps and vascular events. It should only be done by practitioners with specific training for those areas.
- Single use. One syringe, one patient. Discard any remainder.
- Do not inject into infected, inflamed or broken skin.
- Know how to recognise and manage vascular occlusion and nodules.
- Dispose of needles into a sharps container in line with local clinical waste rules.
After treatment
- Redness, swelling, tenderness and bruising are common and settle within days
- Small lumps may be felt at the injection points for a period
- Avoid strenuous exercise, saunas and steam rooms for 48 hours
- Seek urgent review for severe pain, blanching, skin colour change, visual change or a lump that grows or becomes tender

Gouri — frequently asked questions
What is Gouri?
A collagen biostimulator from Dexlevo of South Korea. The active ingredient is polycaprolactone (PCL) in a low-viscosity liquid form, supplied as a prefilled syringe.
Is Gouri a filler?
Dexlevo describes it as a liquid polymer filler, but in practice it works as a biostimulator. It does not add immediate volume and is intended to prompt collagen over weeks to months. Use a hyaluronic acid filler for immediate volume.
What is the injection technique?
The listed technique uses five points on each side of the face, after topical numbing cream. Follow the manufacturer’s training and instructions for use.
How soon will patients see results?
Gradually. A biostimulator works over weeks to months, so we do not promise visible results after a single treatment. Plan a review before any repeat.
Does it lift the face?
It is intended to improve skin firmness and quality, which can give a subtle change in how the skin looks. It is not a substitute for a surgical lift or a volumising filler.
Is Gouri FDA approved?
We do not hold FDA documentation for Gouri. PCL is used in several collagen stimulators sold in different markets, but this does not mean that Gouri itself is approved in your country. Confirm its status before you buy.
What are the risks?
Bruising, swelling, tenderness and lumps at the injection points are the most common. Rarely, vascular complications and nodules can occur. Practitioners must know how to recognise and manage them.
How does it compare with Profhilo or a skin booster?
Profhilo and HA boosters hydrate the dermis. Gouri is a PCL biostimulator intended to prompt collagen. They suit different goals and can be part of the same treatment plan.
Who can buy and use this product?
Injectable products are for administration by licensed healthcare practitioners. We supply qualified professionals and do not sell to consumers.

Happy with my purchase. Customer service was also very helpful.
You need patience with this one. I didn't see much at first but now I get the hype.
This taught me not to evaluate treatments every 24 hours. I couldn't see much happening day to day, but pictures taken several weeks apart told a completely different story.
At first I genuinely couldn't decide whether anything was happening. A few weeks later my skin started looking noticeably more refreshed, so I'm glad I didn't judge it too early.
This is difficult to rate immediately because the changes are so gradual. A friend I hadn't seen for a while said I looked refreshed, and that was when I really started noticing it myself.
I understood this wasn't supposed to be instant, but I still got impatient halfway through. Glad I waited before deciding because the later improvement was much more noticeable.
Don't expect to wake up one morning looking completely different. Mine was more of a slow improvement in the overall look of my skin, and I'm actually happier with that.
Very hard to evaluate this one too early. I almost wrote it off, then compared pictures from two months apart and changed my mind. The overall skin quality definitely looks better.
Someone told me not to keep checking the mirror every morning and they were right. I stopped thinking about it for a while, then suddenly noticed my skin looked better.
Very much a trust-the-process kind of treatment in my experience. There wasn't a single dramatic moment, but the overall difference became noticeable later.
