Expert tips for healthy skin

"Doctor, is GOURI really safe to use under the eyes, even though the skin there is so thin?"
This is a frequent question at Forever in Myeongdong, Seoul whenever GOURI is brought up. Usually, fillers and boosters come with specific area restrictions, but GOURI is often mentioned alongside delicate spots like under the eyes.
The secret lies in the form of GOURI - it's a liquid.
Key Takeaways
- GOURI is a collagen booster made by liquefying PCL (Polycaprolactone), a biostimulant.
- Difference from traditional PCL: It's fully dissolved in liquid form rather than having suspended particles, allowing it to spread evenly without clumping.
- Reason for use under the eyes: It spreads smoothly, even on thin areas. (Application and extent depend on individual skin conditions.)
- Mechanism: Instead of filling, it stimulates your skin to produce collagen. Changes occur gradually and vary from person to person.
Today, let's explore why the term 'liquid' is crucial and how GOURI works, using its application under the eyes as a starting point. We'll break it down in straightforward terms.
In short, GOURI is a collagen booster made from PCL (Polycaprolactone) in liquid form. Known as a 'liquid collagen booster,' it belongs to the skin booster family, but it does more than simply hydrate the skin. For context, PCL is a well-established biocompatible material that has long been used in absorbable surgical sutures and gradually breaks down inside the body.

Remember these two key terms:
"Is it adding collagen, or does it make my skin produce it?"
This is a common question, and the answer is the latter. GOURI doesn't fill in collagen; it stimulates your skin cells to produce new collagen. We'll delve into this more later.

'Liquid' matters because it lets GOURI spread evenly instead of clumping in one spot, which is what makes it usable even on thin areas like under the eyes. The key is in how it spreads: particle-based products can cluster, while liquids disperse evenly.
Let's break it down. Traditional PCL products used for collagen stimulation often come in the form of tiny particles suspended in a gel. While effective, these particles can cluster at the injection site.
GOURI, however, is made by completely dissolving PCL into a liquid. Without suspended particles, it spreads evenly through tissues when injected.

💡 Think of it like this - It's the difference between sprinkling sand and dissolving sugar in water. Sand (particles) settles and clusters, but dissolved sugar (liquid) spreads evenly throughout. GOURI's 'liquid' is akin to the 'dissolved sugar.'
Here's a comparison of the two forms:
| Type | Particle-Based PCL | Liquid PCL (GOURI) |
|---|---|---|
| Form | Tiny particles suspended in gel | Fully dissolved liquid |
| Dispersion | Tends to cluster at injection site | Spreads evenly through tissues |
| Clumping | More likely | Less likely |
| Application | Focused on specific areas | Suitable for broad, thin areas |
⚠️ Note - These are general characteristics, not a statement of superiority. The best choice depends on your purpose, area of application, and skin condition. It's essential to tailor the treatment to your specific needs.
The skin under the eyes is thin, so clumping is noticeable. GOURI's liquid form spreads evenly, making it well-suited for such areas. The characteristic of 'spreading evenly' is the reason behind its suitability.
"The area under my eyes is so delicate, I'm hesitant to do anything there."
That's understandable. Thin areas like under the eyes can easily show clumping on the surface. That's why such areas require careful consideration.
GOURI's liquid form lets it spread thinly and evenly, which makes it well-suited to delicate areas. It's often mentioned for full-face applications, too, because it can evenly treat broad surfaces.
But just to be clear, using it on thin areas doesn't mean it's right for everyone or everywhere. It depends on skin condition, past treatments, and how your skin is doing that day. That's something we determine by examining the skin in person.
GOURI works by stimulating skin cells to produce new collagen, rather than adding collagen directly. Thus, changes appear gradually over time.
Let's explain further. The PCL in GOURI breaks down slowly inside the skin, during which it stimulates the fibroblasts to produce collagen. The stimulated cells generate new collagen and elastin fibers. This process is known as biostimulation (collagen booster).

Thus, collagen boosters differ from fillers.
💡 To illustrate - It's like the difference between placing an artificial flower (filler) and planting a seed (booster). The seed grows directly in your pot. It's not about which is better; they serve different purposes.
⚠️ Hence, expectations vary - Collagen boosters aren't about 'instant dramatic change.' Collagen formation takes time, and results vary significantly among individuals. So it's best not to judge the result after just one session.
GOURI tends to suit people who want to refine the whole face naturally rather than fill one specific spot. There's no one-size-fits-all answer, so it's worth seeing whether GOURI's characteristics (evenly spreading collagen stimulation) match your concerns. Generally, these are some considerations:
🩺 Doctor's Note - In practice, those interested in GOURI often seek 'overall natural enhancement' rather than 'filling a specific spot.' At Forever in Myeongdong, Seoul, we recommend GOURI by considering skin condition and desired outcome, not automatically. Different concerns might be better addressed with other approaches.
It's closer to a collagen booster (biostimulation). Unlike fillers that add volume, GOURI stimulates your skin to produce collagen. Therefore, changes appear gradually and vary from person to person.
Collagen formation takes time, so expect gradual improvement rather than immediate results. However, the timing and extent vary greatly among individuals. It's best to monitor your skin's response over time.
GOURI's even-spreading liquid form is generally well-suited for thin areas like under the eyes. However, 'okay' doesn't mean it's universally applicable. Decisions should be based on direct skin assessment.
The main difference is the form. While traditional products often have suspended particles, GOURI is fully dissolved into a liquid. This prevents clumping and allows even distribution. Choice depends on purpose and area of application.
Collagen boosters usually involve ongoing assessment, so frequency and intervals depend on skin condition and objectives. There's no fixed formula; adjustments are made based on skin evaluation.
The possibility of combination depends on skin condition and treatment type, making it difficult to generalize. If you're receiving or planning other treatments, let us know so we can provide guidance that avoids overlap.
GOURI's suitability for delicate areas like under the eyes is due to its 'liquid' form that spreads evenly without clumping. This characteristic broadens its application range.
Remember, GOURI doesn't add collagen; it helps your skin to produce it naturally, with changes emerging gradually. Instead of expecting instant transformation, think of it as a way to naturally enhance your skin's texture.
Ultimately, whether this approach suits your skin is a matter of direct assessment, which is exactly how we look at it at Forever in Myeongdong, Seoul. With today's insights, you'll have a clearer understanding of why GOURI is used the way it is.
