Kkeut Clinic Layering Technique Process *1. Preparation & Cleansing - If necessary, apply cooling or anesthetic cream Kkeut Clinic Skinbooster 4-D Layering Program *2. 4th Skinbooster Layering (MTS or Secret RF treatment) 1st Skinbooster Ampoule Application - Apply thinly and uniformly (priming) - Induce epidermal skin reaction 2nd Skinbooster Ampoule Application - Apply after shallow needling targeting the epidermal layer 3rd Skinbooster Ampoule Application - Apply after needling targeting the dermal-epidermal junction basement membrane 4th Skinbooster Ampoule Application - Apply after intensive target needling on areas the client wants to focus on (e.g., pores, scars) *3. Soothing Care - Finish with Jauungo modeling pack for soothing management Kkeut Clinic performs 4 layers of application in a single session to ensure the skinbooster is absorbed widely and uniformly. Kkeut Clinic's skinbooster layering program is a safe procedure with almost no risks such as bruising, swelling, injection error, or hypersensitivity reactions. Kkeut Clinic's Absorption Method: Layering Technique Since Juvelook is difficult to absorb with simple topical application, Kkeut Clinic uses MTS (Microneedle Therapy System) and Needle RF (Secret RF) to perform the skinbooster layering absorption technique. The particle size of Juvelook skinbooster is approximately 30-50μm, so it can be sufficiently absorbed with MTS and Secret RF, but to further reduce drug damage from the application method, the layering technique is used for treatment. MTS Layering Technique MTS creates channels of approximately 150μm in size on the skin, forming drug absorption pathways. Kkeut Clinic maximizes absorption rate by layering MTS in 4 stages: Epidermal layer priming application Shallow needling followed by epidermal layer target application Dermal-epidermal junction target application Custom target application on focus areas (pores, scars, etc.) Afterward, the treatment is concluded with soothing care such as a Jauungo modeling pack, minimizing inflammatory reactions. Secret RF Needle RF Layering Technique After forming channels of approximately 180μm, radiofrequency heat is used to constrict the pathways, preventing fluid reflux (overflow) that occurs with conventional needle injections, thereby allowing Juvelook to be absorbed into the dermal layer more accurately with less drug loss. Although there is more drug loss than with manual injection, it has the advantage of being uniformly delivered to the desired target layer (dermis), with less pain and uniform absorption. Similar to MTS, needle depth can be customized, so a 4-stage layering technique is performed. Kkeut Clinic appropriately combines MTS and Secret RF depending on the patient's skin condition. Why does Kkeut Clinic perform treatments this way? Since Juvelook is provided in powder form, it must be sufficiently hydrated with saline to stabilize its viscosity. When performing treatments with manual injections, if hydration is insufficient or depth control is incorrect, the drug may clump, leading to nodules. If it enters the subcutaneous fat layer instead of the dermis, the desired effect may not be achieved. In particular, even with consistent hydration, it is difficult to conclude that there will be absolutely no side effects like nodules when injecting. Therefore, Kkeut Clinic performs treatments in a way that is as safe and effective as possible for our clients. Kkeut Clinic designs treatments to ensure accurate drug absorption, from drug hydration and viscosity control to channel creation and absorption methods, using layering techniques and customized procedures based on skin condition. We believe it is correct to perform treatments that maximize effectiveness while minimizing risks. What is Juvelook Skinbooster? Juvelook (Juvelook) is a next-generation skinbooster that combines PDLLA (Poly-D,L-lactic acid) and hyaluronic acid (HA). It is gaining attention as a regenerative skinbooster that not only improves skin texture, pores, fine wrinkles, and acne scars but also induces the regeneration of autologous collagen and elastin in the dermis, enhancing overall skin elasticity and density. PDLLA is characterized by smaller particles than conventional PLLA (ingredients like Sculptra which have large particles and potential for nodules), resulting in excellent absorption and high safety. Its design allows it to be delivered deep into the skin while reducing inflammatory reactions and the possibility of nodules, making it suitable for those with high skin sensitivity. Juvelook contains the following ingredients: PDLLA 42.5mg (autologous collagen regeneration-inducing component) Non-crosslinked hyaluronic acid 7.5mg (moisture supply and skin barrier improvement) When PDLLA is injected into the dermis, it stimulates fibroblasts to promote the production of collagen and elastin fibers. Since collagen determines skin thickness and density, and elastin determines elasticity, the simultaneous increase of both fibers fundamentally helps improve fine wrinkles, pores, and loss of elasticity. Furthermore, PDLLA also stimulates stem cells to induce the differentiation of new fibroblasts, effectively rebuilding the skin structure itself by replacing existing aged cell structures. Fibroblasts that produce collagen and elastin fibers often do not form anew. Juvelook Skinbooster, instead of stimulating these aging fibroblasts, participates in the formation of new fibroblasts, thereby maximizing long-term collagen and elastin fiber production. Recommended for: 01. Those concerned about skin elasticity and enlarged pores 02. Those concerned about pores, acne scars, etc. 03. Those who desire natural volume improvement without obvious signs 04. Those with uneven skin texture and bothersome fine wrinkles 05. Those who want autologous collagen regeneration but are reluctant to undergo injection procedures 06. Those who desire natural and healthy skin tightening and lifting What is the clinical basis for Juvelook? The dermal regenerative effects of PDLLA have been proven in numerous studies. Kwon et al., Dermatologic Surgery, 2022: After 3 treatments with PDLLA skinbooster at 4-week intervals, increased skin thickness, improved dermal density, and enhanced elasticity were confirmed. Kim et al., Journal of Cosmetic Dermatology, 2021: Confirmed that PDLLA induces elastin production, demonstrating more diverse fiber regeneration effects than typical collagen-focused products. Han et al., Lasers in Surgery and Medicine, 2020: In a study on patients with acne scars, MTS-based absorption method was effective in delivering the drug to the dermis with less epidermal stimulation and side effects. A message from the Director Among those who visit our clinic for the first time, many are deeply concerned about their skin texture alone. Broad pores or rough texture leading to makeup not sitting well. Others might not know, but for the individual, it's quite a significant source of stress. We recommend Juvelook for such individuals. This is because it is a treatment that helps smooth out skin texture, tighten pores, and restore the skin's self-healing power. For those who are usually afraid of injection procedures due to pain, or those who were concerned about drug loss, we sincerely hope you experience the Juvelook skinbooster with Kkeut Clinic's layering technique. Advantages of the treatment 01. FDA-approved in the US, combination of high-molecular PLA + hyaluronic acid to improve problematic skin 02. Promotes autologous collagen regeneration for natural results over time 03. Improves skin elasticity, skin texture, fine wrinkles, and acne scars 04. Biodegradable and bioabsorbable, leaving no residue in the body after a certain period
