First things first — what exactly is GOURI?

GOURI has been popping up everywhere in skincare and aesthetics communities lately — and I'll admit, I had no idea what it was at first. To put it simply, it's a fully liquid PCL (Polycaprolactone)-based collagen booster injection. It holds official approval in Korea and has earned European CE certification, so its safety profile is already well-established.

PCL itself is a bioabsorbable polymer that has been used in medicine for decades — think dissolvable sutures and drug-delivery capsules. In aesthetics, it works by gradually breaking down inside the body while stimulating collagen production along the way.

Traditional PCL-based products come in solid or semi-solid forms, which can lead to clumping or uneven distribution under the skin. GOURI's defining feature is that it's completely liquid — no particles, no clumps, just smooth and even spread throughout the treated area.

Why I Decided to Try It on Myself First

To be completely honest, I spent a long time deliberating before adding Gouri to our treatment lineup. No matter how well a product is approved and regulated, I need to build up enough firsthand clinical experience before I can confidently recommend it to my patients. So the conclusion I reached was simple — I would be my own first patient.

As the person administering the treatment, it's easy to overlook what the patient actually feels — the sensation of the needle entering the skin, how the solution spreads, the pattern of swelling and bruising that follows. I genuinely believe that experiencing it yourself is the only way to have a truly empathetic conversation with your patients.

I'm in my early 40s, and over the past few years I've noticed a real decline in my skin's elasticity and overall volume. I had been feeling that what I needed wasn't an instant volumizing fix like filler, but rather an approach focused on gradually restoring my skin's own health from within — so the timing felt right.

What Actually Happened on the Day of My Treatment

In my case, the treatment covered my entire face — forehead, temples, cheeks, and jawline. Since Gouri is injected densely into the dermis, the number of injection points isn't small. That's why a numbing cream was applied thoroughly before we got started.

I know you're probably curious about the pain, so I'll be honest — thanks to the numbing cream, the injections themselves weren't bad at all. That said, areas where the skin sits directly over bone, like the forehead and temples, did feel a bit more sensitive. The best way I can describe it is a sharp prick followed by a feeling of pressure.

What struck me most was the sensation of the solution spreading. With conventional solid-particle PCL products, you can really feel the resistance as it's pushed in. Gouri was completely different — it flowed in like water, almost effortlessly. It was a genuinely new experience, both as a patient and as someone familiar with these treatments.

The total treatment time, not including the numbing period, was around 20 to 25 minutes.

Right After the Treatment: Honest Day-One Changes

The first thing I noticed was redness — which was completely expected. With multiple needle insertions across the face, my skin looked slightly flushed overall, with small pinpoint bruises scattered here and there. The cheek area was a bit more noticeable than the rest.

The swelling was milder than I anticipated — more of a subtle puffiness than anything dramatic. When I pressed on the skin, there was a slight firmness, which makes sense since the solution hadn't fully dispersed yet. Over the next day or two, it gradually integrates with the surrounding tissue and softens naturally.

One thing worth noting — no lumps whatsoever. This was actually one of the biggest reasons I wanted to try this treatment firsthand. When I pressed along each injection site, everything felt evenly distributed. It was a completely different experience from solid-particle PCL products I'd used in the past, where you'd occasionally feel tiny nodules under the skin.

By the evening of treatment day, my skin felt slightly tight and sensitive to the touch. I cleansed with water only and kept my skincare routine to an absolute minimum. Makeup was fine to resume the following day.

Who Is a Good Candidate — and Who Should Think Twice

Why Cellon Clinic Chose Gouri — From the Director's Perspective

Cellon Clinic is a Ministry of Health and Welfare Designated Advanced Regenerative Medicine Hospital. Because our treatment lineup is built around regenerative procedures, we hold any new addition to a high standard. It's never just about a product being new or trending — we first ask: is the regenerative mechanism clearly established, and is there sufficient evidence of safety?

Gouri met our criteria on several fronts: it uses PCL, an already well-validated ingredient, reformulated into a liquid form, and it has obtained both CE certification and approval from Korea's Ministry of Food and Drug Safety. On top of that, I received the treatment myself and was able to confirm firsthand that it distributes evenly without any lumping or irregularities — which was a deciding factor in bringing it on.

At Cellon Clinic, we use Gouri both as a standalone treatment and in combination with other regenerative procedures such as Exosome therapy and Rejuran. The right approach varies depending on your skin condition, so we always recommend a thorough consultation before deciding on any combination.
