There are many skin-beauty methods for concealing wrinkles and filling volume.
But if structural problems inside the skin are not addressed, aging effects eventually return over time. For that reason, more people are turning to anti-aging solutions that go beyond surface care and improve the skin's own regenerative ability and structural function.
In particular, skin booster approaches that improve the fundamental environment of the dermis and focus on regenerating the skin structure itself are drawing attention. Today we take a closer look at how GOURI, a fully liquid PCL solution designed to overcome the limits of microparticle formulations, works and what its features are.
What sets GOURI liquid skin booster apart
1. GOURI compared with existing skin boosters and fillers
How well each solution suits you depends on your skin concerns and goals, so it is most important to understand your skin condition precisely before choosing a treatment.
| Category | Filler | Rejuran Healer | Juvelook | GOURI |
|---|---|---|---|---|
| Ingredient / formulation | Cross-linked HA (gel) | PN (viscous liquid) | PDLLA (microparticles) | PCL (fully liquid) |
| Main purpose | Local volume filling | Improving skin texture / epidermal environment | Local volume / firmness by area | Overall facial tightening & collagen regeneration |
| Features | Immediate contour volume | Hydration and barrier strengthening | Particle-based cell stimulation | Minimal nodule concern / excellent spread |

2. GOURI goes beyond simple volume: remodeling skin structure
GOURI is not a one-off treatment that simply adds physical volume to hollow areas. It continuously stimulates fibroblasts in the dermis to improve the skin tissue's own regenerative ability at its source.
This aims to improve complex aging signs together, such as loss of firmness, fine lines and dull skin texture. Because the formulation is very smooth and spreads evenly over a wide area, it can be applied naturally, without looking artificial, even to thin-skinned areas around the eyes, the forehead and neck lines, which used to be difficult to treat, making it highly versatile.

3. Why precise technique matters given GOURI's high diffusion
Because this is a high-end treatment that can be used on many areas, the procedure calls for an even more careful and meticulous approach. The GOURI skin booster has high diffusion with excellent fluidity. That is an advantage, but it also means that, if technique is lacking, it can spread unintentionally into surrounding tissue and reduce the concentrated effect on a specific target area.
① Personalized diagnosis
Skin thickness, elasticity, dermis depth and even the way your expression muscles are used should be analyzed together.
② Combined solution design
If deep, localized hollowing is the main concern, combining Juvelook or a filler, and if the goal is hydration and texture of the epidermis, combining Rejuran, may give a more efficient result.
In other words, rather than insisting on GOURI alone, it is better to decide through close communication with a medical professional whether GOURI is the most suitable option for your skin type.
One-to-one personal design at Gangnam Pieobom Clinic
At Gangnam Pieobom Clinic, Dr. Hyoseung Jang, who serves as President of the Korean Association of Clinical Aesthetic Medicine, personally takes charge of the entire process, from consultation to treatment.
After carefully analyzing your skin thickness, stage of aging, fat accumulation and individual needs through one-to-one communication, a one-to-one personal design is created.
A difference in experience becomes a difference in results. A liquid PCL solution requires careful calculation of the formulation's diffusion and the injection depth for each skin layer, so please proceed carefully with medical staff who have long clinical know-how and solid skill.
Frequently Asked Questions
How long do bruising, swelling and downtime last after GOURI?
Because it is a liquid formulation, absorption into the skin tissue after injection is relatively quick. Slight swelling or injection marks may appear right after treatment, but they usually settle naturally within 1-3 days, so you can return to daily life right away.
How many sessions are recommended, and how long do results last?
About 3 consecutive sessions at 4-week intervals are usually recommended. Collagen remodeling in the dermis proceeds gradually after treatment, and the newly formed collagen is described as keeping the skin firm and smooth for one year to one and a half years or more. Individual results vary.
Is there really no risk of nodules (clumping) after GOURI?
Unlike existing PCL/PLLA treatments that contain particles, GOURI is a fully dissolved 'liquid' formulation. The risk of nodules or granulomas caused by particle clumping is therefore described as considerably lower, and it is well regarded for safety. This does not mean the risk is zero, and results vary by individual.
Can it be used safely on thin-skinned areas such as around the eyes or the forehead?
Yes, it is possible. One of GOURI's biggest strengths is its excellent diffusion and softness. It blends naturally into the dermis without showing through, the Tyndall effect or a floating feeling, so it is also used for fine lines around the eyes and for forehead firmness.
Can it be combined with other skin boosters (Rejuran, Juvelook, etc.) or laser lifting?
Yes, combining may offer a complementary effect. For example, a combined plan is possible in which skin-surface texture is refined with Rejuran and overall dermal firmness is addressed with GOURI. The interval and order of treatments should be decided after consulting your doctor, depending on your skin condition.
