What is PCL Skin Booster?

PCL Skin Booster is composed of PCL (Polycaprolactone), a completely solubilized liquid form with no particles.

When PCL enters the dermis, it smoothly diffuses throughout the skin, continuously stimulating fibroblasts to produce collagen and elastin. This leads to improvements in fine lines, skin texture, overall skin density and elasticity, and anti-aging effects.

Kkeut Clinic's Layering Technique Process

1. Preparation & Cleansing

Cooling or anesthetic cream application if necessary

Kkeut Clinic's Skin Booster 4-D Layering Program

2. 4-Stage Skin Booster Layering (MTS or Potenza RF Treatment)

1st Skin Booster Ampoule Application: Apply thinly and overall (priming) / Induce epidermal skin reaction

2nd Skin Booster Ampoule Application: Apply after shallow needling targeting the epidermis

3rd Skin Booster Ampoule Application: Apply after needling targeting the dermal-epidermal junction basement membrane

4th Skin Booster Ampoule Application: Apply after intensive needling targeting areas the client wants to focus on (e.g., fine lines, reduced elasticity)

3. Soothing Care

Finish with Jaungo Modeling Pack for soothing care

Kkeut Clinic performs 4 stages of layering in a single treatment to ensure the skin booster is absorbed widely and uniformly.

Kkeut Clinic's Skin Booster Layering Program is a treatment designed with safety in mind, significantly reducing risks such as bruising, swelling, injection errors, and hypersensitivity reactions.

Kkeut Clinic's Absorption Method: Layering Technique

To ensure the high-molecular active ingredients of PCL Skin Booster are smoothly delivered to the dermis, Kkeut Clinic utilizes MTS (Microneedle Therapy System) and needle RF (Secret RF/Potenza) for its skin booster layering absorption technique.

PCL Skin Booster has a pure liquid formulation with no solid particles, giving it excellent spreadability when entering the dermal layer. Kkeut Clinic uses a customized layering technique to reduce drug loss and ensure uniform delivery throughout the dermis.

MTS Layering Technique

MTS creates channels approximately 150μm in size in the skin, forming pathways for drug absorption. Kkeut Clinic layers MTS in 4 stages to maximize absorption efficiency.

Epidermal Priming Application

Epidermal Target Application after shallow needling

Dermal-Epidermal Junction Target Application

Custom Target Application for focused areas (e.g., fine lines, eye area, reduced elasticity)

The treatment is then concluded with soothing care, such as a Jaungo modeling pack, ensuring no inflammatory reactions.

Potenza RF Needle Radiofrequency Layering Technique

After creating approximately 180μm channels, RF heat is used to constrict the pathways, preventing fluid backflow (overflow) that occurs with conventional needle injections. This allows for more precise absorption of PCL into the dermis with less drug loss.

Compared to manual injection, it prevents drug loss while ensuring uniform delivery to the desired target layer, the dermis. It offers the advantages of less pain and even absorption. Similar to MTS, needle depth can be customized, allowing for a 4-stage layering technique.

Kkeut Clinic appropriately combines MTS and Potenza RF according to the patient's skin condition.

Why does Kkeut Clinic use this treatment method?

PCL ingredients have the characteristics of a high-molecular liquid formulation.

If administered by manual injection, incorrect depth control or pooling on the skin's surface can leave temporary bumps or irritation. If injected too deeply into the subcutaneous fat layer, the desired dermal regeneration effect may not be fully achieved.

Particularly to reduce the possibility of side effects such as bruising, swelling, pain, and injection errors that can occur during injection procedures, Kkeut Clinic aims to provide treatments that are as safe as possible for clients while maximizing their effectiveness.

From channel creation to absorption method, Kkeut Clinic designs customized treatments with layering techniques tailored to skin condition, ensuring that PCL's active ingredients are precisely absorbed into the dermis.

We determined that treatments maximizing efficacy while minimizing risks are the correct approach.

Key Actions of PCL Skin Booster:

Induces self-collagen and elastin regeneration (Dermal structure rebuilding)

Minimizes nodule risk with a particle-free, fully liquid structure

When PCL is delivered into the dermis, it stimulates fibroblasts to promote collagen and elastin fiber production.

Collagen is a crucial component that determines skin thickness and density, while elastin determines elasticity. Therefore, increasing both fibers simultaneously helps restore thinned dermal thickness and fundamentally improves fine wrinkles and loss of elasticity.

Furthermore, PCL polymers continuously stimulate the body to produce autologous collagen, and after a certain period, they completely break down into water and carbon dioxide and are safely expelled from the body.

What is the difference with Juvelook?

Many people are curious about the difference between Juvelook (PDLLA), a well-known collagen skin booster, and PCL skin boosters. The two treatments have clear differences in the formulation characteristics of their active ingredients and their main target effects.

Differences in Formulation and Mechanism of Action

Juvelook is injected by hydrating fine porous particles in water, intensely stimulating the surrounding tissues to regenerate new skin. In contrast, PCL skin booster is a fully solubilized liquid formulation with no particles. The biggest difference is that when injected into the skin, it smoothly diffuses throughout the surrounding tissues without clumping, forming a 3D matrix.

Differences in Main Improvement Objectives

Juvelook excels in improving sunken acne scars, enlarged pores, and localized volume and texture in specific areas. PCL skin booster, on the other hand, is more specialized in improving overall facial fine lines, restoring thinned dermal thickness, and rebooting firm skin density and elasticity across the entire face.

Safety and Formulation Characteristics

PCL skin booster has the advantage of minimizing the risk of nodule (particle clumping) side effects, which are a concern during injectable procedures, because no solid particles exist in its formulation.

Recommended for

Those concerned about reduced skin elasticity and fine lines across the face

Those whose skin has thinned, losing density and firmness

Those concerned about nodule (clumping) side effects, bruising, or swelling from injectable procedures

Those with rough skin texture who desire a subtle, smooth skin reboot

Those looking for a safe autologous collagen regeneration treatment with minimal pain

Those who desire a natural skin tightening effect

What is the clinical evidence for PCL?

Numerous studies have proven the dermal regeneration and collagen induction effects of PCL.

Continuous Collagen Bioreaction of PCL Polymer: PCL has been shown to stimulate fibroblasts in the dermal layer of the body, promoting the neogenesis of Type I and Type III collagen and elastin.

Stability and Diffusibility of Solubilized PCL: Liquid PCL, unlike its particulate form, uniformly diffuses into surrounding tissues when injected into the dermal layer, improving dermal density without clumping.

Efficiency of MTS/RF-based Delivery System: Drug delivery via micro-channels safely diffuses the substance throughout the dermal layer while reducing epidermal irritation and bleeding compared to manual injection.

A Message from the Head Director

"As we age, skin thins and fine lines increase due to a reduction in collagen and density in the dermal layer. Many people are concerned about the superficial elasticity they see in the mirror.

We recommend PCL skin boosters for such individuals.

This is because it is a treatment with a pure liquid structure without particles, reducing the risk of clumping, and it spreads smoothly throughout the entire dermis, restoring firm strength from deep within the skin.

"For those who usually found pain or injection marks burdensome, or those who sought a safe treatment with reduced concerns about nodule side effects, we highly recommend experiencing PCL skin booster with Kkeut Clinic's layering technique."

Q&A

Q. What is the recommended treatment interval?

A. We usually recommend 2-3 sessions at 4-week intervals, followed by maintenance care tailored to your individual skin condition.

Q. What is PCL Skin Booster?

A. PCL Skin Booster is a self-tissue regenerating collagen booster made from high-molecular PCL (Polycaprolactone). It is a completely liquid form with no particles, safely degrading in the body without leaving residues. It spreads widely throughout the dermis, inducing long-term collagen production and increasing skin density and elasticity.

Q. Are there any treatments that can be done together?

A. When performed with Potenza RF, the effects are doubled. Potenza inserts micro-needles into the dermal layer to deliver high-frequency thermal energy, helping to generate new collagen. Especially, using KKEUT Clinic's layering technique, medication loss is reduced, and it is effectively delivered to the dermis without pain.

Q. When do the effects appear?

A. From 2-3 weeks after the treatment, you will notice improved skin texture and a soft, hydrated feel. After 1-2 months, when PCL diffuses within the dermis and actively remodels collagen, skin density and elasticity will become noticeably enhanced.

AFTERCARE GUIDE (Precautions)

Temporary redness, minor swelling, and slight bumps may occur at the treatment site, which usually resolve naturally within 1-3 days.

For 1 week after the treatment, please avoid alcohol and smoking, saunas, swimming pools, and strenuous exercise.

Do not rub or excessively stimulate the treated area.

Avoid using scrub products for 1 week as they can irritate the skin.
