Dr. Hyo-Hyun Seok, Medical Director of AllLiting Plastic Surgery, announced that he was invited to the 'Thermage User Symposium' to share his clinical expertise and advanced anti-aging treatment protocols. The symposium brought together prominent domestic and international aesthetic professionals to discuss the latest clinical utilities and safe, effective procedural know-how for the monopolar radiofrequency (RF) device, 'Thermage FLX.'

Thermage FLX is a premier non-invasive anti-aging procedure that delivers uniform radiofrequency energy into the dermal layer while protecting the epidermis, thereby stimulating natural collagen remodeling. It continues to enjoy high patient preference in the aesthetic market due to its exceptional efficacy in improving fine wrinkles, enhancing skin elasticity, and achieving comprehensive skin tightening.

During his lecture, Dr. Seok underscored the critical need for customized energy distribution and vector mapping tailored to each patient's facial contour and anatomical structure. Rather than applying a fixed number of shots, his custom-designed clinical approach received widespread acclaim from participating medical professionals.

Dr. Hyo-Hyun Seok stated, "Thermage treatment is not about simply delivering a predetermined number of shots; the clinical outcome hinges on accurately evaluating individual skin conditions and subcutaneous fat thickness to fine-tune energy delivery. It was a meaningful opportunity to exchange academic insights with fellow practitioners, and I will continue my research to provide patients with safer, highly satisfying lifting solutions."

[Press Q&A]

Q1. What is the mechanism behind Thermage FLX for improving skin elasticity?

"Thermage FLX delivers monopolar radiofrequency (RF) energy into the dermal layer to induce collagen contraction and stimulate neocollagenesis. As the targeted thermal energy encourages new collagen formation over time, patients achieve a refined skin tightening effect characterized by naturally firmer skin and softened fine lines."

Q2. What defines the 'customized treatment' you emphasized at the symposium?

"Every individual possesses distinct skin thickness, hydration levels, adipose tissue distribution, and aging velocity. Applying a uniform shot count or energy level cannot deliver optimal results. The essence lies in evaluating localized skin conditions through meticulous pre-treatment diagnosis and distributing shots with consideration to energy depth and vectors. We emphasize a '1:1 custom design treatment' harmonized with individual facial architecture."

Q3. What should patients keep in mind when considering Thermage procedures?

"First is verifying the authenticity of the treatment tip. Reused or counterfeit tips significantly increase the risk of adverse reactions and diminish clinical efficacy; verifying genuine tips and authentic devices is essential. Second is the practitioner's procedural expertise. Because Thermage requires delicate energy calibration, receiving treatment from a board-certified plastic surgeon or dermatologist with extensive clinical experience and facial anatomical insight ensures safe, optimal outcomes."

Q4. What clinical synergy is achieved when combining Thermage with other lifting treatments such as Ultherapy?

"While Thermage excels at superficial and dermal 'tightening' by regenerating collagen to make the skin firm and elastic, Ultherapy specializes in deep structural 'lifting' by targeting the SMAS (Superficial Musculoaponeurotic System) layer. Combining both treatments—often referred to as 'Ul-Thermage'—provides comprehensive multi-layer rejuvenation from the deep supporting structures to the cutaneous surface, maximizing anti-aging synergy."

Dr. Hyo-Hyun Seok, Medical Director of AllLiting Plastic Surgery, announced his participation as a key advisory specialist in authoring the official clinical guide for 'Silhouette Soft', the premium thread lifting treatment by Sinclair, aimed at enhancing clinical competencies and fostering a safe medical environment.

This guidebook serves as a specialized manual for domestic plastic surgeons and dermatologists performing or adopting Silhouette Soft procedures. It provides in-depth coverage of customized design methods tailored to individual facial contours and skin laxity, advanced techniques to minimize complications while maximizing lifting longevity, and detailed analyses of real-world clinical cases.

Silhouette Soft is a premium thread lifting procedure utilizing 360-degree bidirectional cones to achieve robust fixation and structural tissue repositioning. Formulated with fully bioabsorbable Poly L-Lactic Acid (PLLA), it delivers immediate mechanical lifting while actively stimulating autologous collagen synthesis over time. Because procedural outcomes rely heavily on the physician’s technical dexterity and precise vector engineering, it is recognized as a procedure demanding advanced surgical expertise.

Having accumulated extensive clinical experience, Dr. Hyo-Hyun Seok of AllLiting Plastic Surgery has served actively as a Key Opinion Leader (KOL) in global academic conferences and symposia. Through this guidebook, Dr. Seok has presented standardized protocols for the sophisticated Silhouette Soft procedure, earning widespread acclaim for helping practitioners execute safer and more systematic treatments.

Dr. Hyo-Hyun Seok stated, "Silhouette Soft is a procedure that goes beyond simple lifting; it requires an organic design of overall facial volume and contours. I hope this guidebook serves as a practical asset for fellow practitioners and stands as a benchmark for providing safer, highly satisfactory medical outcomes to patients."

[Q&A Interview]

Q1. What motivated your participation in authoring this 'Silhouette Soft Treatment Guide'?

"While Silhouette Soft is an exceptional premium procedure that allows flexible and organic facial remodeling, results can vary significantly based on practitioner technique. I chose to participate as an advisory author to share the clinical know-how and safe treatment protocols I have developed, helping fellow practitioners minimize trial and error while delivering safer, highly refined results to patients."

Q2. What is the most significant differentiator of Silhouette Soft compared to conventional thread lifting?

"The fundamental difference lies in the cone architecture and raw material. Unlike conventional threads that utilize barbed cutting cogs, Silhouette Soft features 360-degree movable bidirectional cones that allow practitioners to freely 'reposition' skin tissue into optimal positions rather than merely pulling it in a fixed direction. Furthermore, the PLLA composition stimulates endogenous collagen production, ensuring long-lasting lifting and volume restoration."

Q3. What is the most critical takeaway medical professionals should focus on in this guidebook?

"Patient-specific 'customized vector design' and 'natural anchoring techniques.' Because areas of laxity and volume deflation vary across individuals, applying a standardized thread pattern often leads to unnatural outcomes. The guide emphasizes accurate design mapping aligned with aging progression and safe anatomical insertion depth to prevent complications."

Q4. What advice would you give to patients considering Silhouette Soft?

"For Silhouette Soft, receiving treatment from a skilled specialist who completely understands facial anatomy and can fully leverage the thread’s distinct properties is essential. Through our contribution to this clinical guide, AllLiting Plastic Surgery remains committed to delivering natural and healthy beauty through continuous research and standardized safety protocols."

Leading the Paradigm Shift in Skin Boosters via Supercritical CO₂ Processed Acellular Human Dermal Matrix (E-cell™)

  Dr. Hyo-Hyun Seok, Medical Director of AllLiting Plastic Surgery, has been officially appointed as a Key Opinion Leader (KOL) for 'Juveàcell', a 5th-generation skin booster derived from human dermal components gaining immense traction in the global aesthetic market. This appointment recognizes Dr. Seok’s extensive clinical experience in anti-aging procedures and his contributions to establishing safe, highly effective treatment protocols.

 Juveàcell is an innovative Extracellular Matrix (ECM) booster launched by Vaim Co., Ltd. While conventional skin boosters focus on inducing collagen synthesis indirectly, Juveàcell utilizes proprietary 'Supercritical CO₂ Decellularization Technology (E-cell™ Technology)' to completely eliminate immunogenic substances from human dermal tissue, directly supplying pure human collagen and ECM structural scaffolds into the skin. This minimizes chemical solvent residues and immediately reinforces the structural framework of the skin, demonstrating exceptional efficacy in enhancing elasticity, restoring natural volume, and refining texture.

 As a designated Key Opinion Leader, Dr. Seok will actively engage in academic research, medical seminars, and live surgery demonstrations, providing authoritative clinical guidelines to medical professionals. Juveàcell is supplied in a pre-filled syringe format requiring no reconstitution prior to treatment, significantly reducing the risk of nodule formation or clumping while enabling customized applications for delicate facial zones such as the infraorbital region, cheeks, and perioral lines.

 Dr. Hyo-Hyun Seok stated, "I am honored to serve as a Key Opinion Leader for Juveàcell, an advanced solution that simultaneously addresses skin density improvement and safety—two factors previously lacking in traditional skin boosters. Since every patient exhibits distinct skin thickness and aging velocity, I will continue my academic and clinical endeavors to deliver the safest and most natural skin regeneration outcomes through tailored 3% and 8% concentration protocols."

[Media Q&A] Insights on the 5th-Generation Skin Booster with Juveàcell KOL Dr. Hyo-Hyun Seok of AllLiting Plastic Surgery

Q1. Congratulations on your appointment as a Key Opinion Leader for Juveàcell. Could you share your thoughts?

 "Thank you. It is truly meaningful to serve as a Key Opinion Leader for Juveàcell, which is recognized as one of the most innovative hADM (Human Acellular Dermal Matrix) solutions in the medical aesthetic market. My primary value as a surgeon is delivering 'safe yet definitive outcomes.' Because Juveàcell satisfies both criteria, I look forward to sharing my clinical expertise with colleagues to foster a safer, more effective treatment culture."

Q2. Excellent skin boosters like Rejuran and Juvelook are already established. What is Juveàcell’s biggest differentiator?

 "In short, it is the fundamental difference between a 'signaling stimulant' and 'pre-fabricated construction material.' Traditional products stimulate fibroblasts to encourage collagen synthesis. In contrast, Juveàcell directly implants pure human collagen and ECM—the essential structural foundation of the human dermis. By immediately reinforcing the collapsed skin structure without waiting for self-collagen production, patients with thin, sagging skin experience far more direct and visible regenerative results."

Q3. Juveàcell comes in 3% and 8% concentrations. How do you apply them differently in clinical practice?

 "Applications are strictly customized according to the patient's skin condition and target depth. Juveàcell 3% is ideal for refining skin texture, brightening tone, and tightening thin dermal surfaces, administered densely using manual micro-injections or automated injectors. Juveàcell 8% features a significantly higher collagen concentration and is injected via cannula into deeper layers to increase skin density or add subtle volume to the under-eyes, anterior cheeks, and nasolabial folds, creating a natural, self-regenerated dimensional look rather than an artificial filler appearance."

Q4. Many patients express concern over nodules or severe pain during skin booster treatments. How does Juveàcell perform?
 

 "Its performance is exceptional. Previous powder-form dermal products required reconstitution with saline, risking clumping if insufficiently dissolved. Juveàcell is manufactured as a uniform liquid in pre-filled syringes through advanced processing, dramatically lowering nodule risks. Regarding discomfort, while a slight tightness may occur due to viscosity, the Supercritical CO₂ process minimizes inflammatory responses, resulting in noticeably less pain and higher patient comfort compared to 1st or 2nd generation products."

Q5. What advice would you offer to patients considering Juveàcell treatments?

 "Juveàcell serves as a superior alternative for individuals experiencing thinned skin and sudden loss of elasticity due to aging. However, even premium formulations require precise evaluation of skin thickness and aging progression. I strongly recommend consulting a qualified specialist with extensive anatomical knowledge and clinical expertise to ensure accurate dosage and depth mapping for your specific needs."

Moving beyond conventional dermatological approaches, the seminar featured in-depth discussions on utilizing Juvelook more safely and effectively through a comprehensive understanding of human facial anatomy. Dr. Seok shared essential particle characteristics, hydration techniques, and combination protocols designed to maximize synergy when paired with surgical procedures (such as fat grafting or facelifts) or energy-based lifting lasers.

Capitalizing on his expertise as a plastic surgery specialist, Dr. Seok demonstrated safe layer-by-layer injection techniques for delicate facial areas requiring precise design, including the infraorbital region, nasolabial folds, and sunken cheeks, using live demonstrations and clinical case studies. The core highlight of the seminar was his differentiated technique for achieving natural volume and skin texture restoration while minimizing adverse effects.

Dr. Hyo-Hyun Seok stated, "Juvelook requires precise control of injection depth and dosage tailored to the patient's skin thickness, degree of sagging, and anatomical structure. Sharing clinical guidelines that maximize Juvelook's potential based on accumulated anatomical knowledge and surgical experience was truly meaningful. I will continue academic research to deliver safe and highly satisfying anti-aging outcomes."

[Q&A Interview]

Q1. What distinguishes the plastic surgeon's approach to Juvelook, which served as the main theme of this seminar?

"While standard skin booster treatments focus primarily on improving the superficial dermal environment, a plastic surgeon's approach originates from a comprehensive anatomical perspective encompassing the entire facial architecture. By evaluating muscle dynamics, fat loss, and skin laxity, we target Juvelook and Juvelook Volume to the exact structural layer needed. This distinction delivers structural elasticity and a natural facial contouring effect beyond simple texture refinement."

Q2. Juvelook is known for its synergistic results when combined with other procedures. Which combinations are most effective? 

"Combination protocols featuring energy-based lifting devices like Ultherapy or Thermage are highly effective. While lasers contract the inner dermal layers for tightening, Juvelook stimulates collagen within those spaces to prolong elasticity. Furthermore, it serves as a valuable adjunctive therapy to increase graft survival rates after fat transplantation or to restore intrinsic skin quality following surgical procedures like facelifts."

Q3. Patients often worry about nodule formation with Juvelook. How do you prevent this issue?

"Nodules typically occur when the product clumps or is injected excessively into superficial layers. Prevention requires a meticulous hydration process prior to treatment, followed by uniform injection techniques with consistent pressure at exact anatomical depths. At our clinic, we conduct precise diagnostic evaluations of skin thickness and utilize customized cannulas and injection protocols to minimize risk."

Q4. What advice would you give to patients considering Juvelook treatments?

"Unlike traditional dermal fillers that physically fill space, Juvelook is an autologous regeneration treatment that prompts your skin to produce its own collagen. It is an ideal choice for those seeking natural rejuvenation. However, clinical outcomes depend significantly on the practitioner's anatomical expertise and artistic design. I strongly recommend consulting with a highly experienced specialist before proceeding with treatment."

The paradigm of anti-aging aesthetic procedures is evolving rapidly. Moving away from single-modality treatments focused solely on volume restoration or wrinkle reduction, improving comprehensive 'Skin Quality'—encompassing texture, hydration, radiance, and structural elasticity—has emerged as a central theme. In line with this shift, Dr. Seok Hyo-hyun of AllLiting Plastic Surgery hosted an in-house seminar titled "Synergistic Effects of Skin Boosters and Biostimulators through an Anatomical Approach," presenting advanced skin regeneration solutions.

During the seminar, Dr. Seok highlighted a combination strategy using Merz's flagship hyaluronic acid skin booster 'Belotero Revive' and the CaHA-based biostimulator 'Radiesse' as a core solution driving anti-aging trends in Gangnam. Dr. Seok emphasized, "Modern patients prefer subtle, natural enhancements where their skin appears inherently healthier, rather than artificial surgical changes. To achieve both immediate hydration on the skin surface and sustained collagen regeneration in the deep dermis, a sophisticated dual-acting protocol combining distinct mechanisms is essential."

In the subsequent Q&A session, Dr. Seok further elaborated on the multi-layer skin quality strategy.

Q1. What is driving the growing interest in 'Skin Quality' within plastic surgery?

"While traditional anti-aging in plastic surgery focused on structural shifts like facelifts or fat grafting, patients across all age groups now prioritize intrinsic skin health, texture, tone, and radiance. Flawless facial contours still require refined skin texture to complete a youthful appearance, driving the rapid growth of skin booster and biostimulator markets."

Q2.What are the respective roles of Belotero Revive and Radiesse?

"From a surgical perspective, they are complementary solutions targeting different skin layers. Belotero Revive combines hyaluronic acid with glycerol to deliver immediate hydration and smooth the superficial skin layer for quick, intuitive results. Radiesse, containing Calcium Hydroxylapatite (CaHA), stimulates fibroblasts deep within the dermis to induce extracellular matrix (ECM) components like collagen and elastin, strengthening the structural foundation for long-term regeneration."

Q3. What distinguishes 'Belotero Revive' from other boosters?

"It is the unique hyaluronic acid booster formulation containing glycerol. Glycerol’s powerful hygroscopic properties immediately bind moisture to restore skin barriers post-treatment, enhancing skin translucency and accelerating recovery from dryness."

Q4. What synergistic benefits does the combination strategy offer?

"It enables multi-layer care where surface remodeling and deep structural regeneration occur simultaneously. Belotero Revive refines upper-layer texture and hydration, while Radiesse provides deep dermal support through continuous collagen synthesis. This combined approach delivers comprehensive improvements in fine lines, tone, hydration, and long-term elasticity, while serving as an excellent finishing treatment following surgical lifting."

Q5. What is your outlook on future anti-aging trends?

"The market is moving toward customized clinical design tailored to individual patient anatomy. Anti-aging procedures represent complex medical decisions rather than simple cosmetic injections. Patients should consult thoroughly with experienced specialists who possess deep anatomical insight to formulate safe, multi-layered treatment plans."

[Q&A Interview] Innovation of 'Juveàcell' with Dr. Hyo-Hyun Seok of AllLiting Plastic Surgery

Q. What is driving the emphasis on 'skin quality' in the medical aesthetic field? "Recent treatment trends unequivocally converge on natural beauty and fundamental skin health. Procedures that artificially erase specific wrinkles or overfill volume are declining. Modern patients seek holistic enhancement across texture, tone, elasticity, and hydration. This trend is driven not only by younger demographics seeking preventive care but also by older patients who desire subtle, authentic improvements rather than artificial changes."

Q. How does 'Juveàcell' differ from traditional skin boosters or collagen stimulators? "The primary distinction lies in the raw material and structural mechanism. Traditional collagen boosters stimulate fibroblasts to promote collagen synthesis—acting as a delivery of building materials. Conversely, Juveàcell utilizes human acellular dermal matrix (hADM), providing a pre-formed structural scaffold where cells can immediately reside and thrive. Delivering fully formed collagen and structural components directly yields faster and more reliable regenerative outcomes, particularly for aging or thinned skin."

Q. You highlighted ECM preservation using the 'Supercritical CO₂ Process.' Why is this clinically significant? "Preserving the Extracellular Matrix (ECM) is vital for authentic skin regeneration. The ECM serves as a structural framework composed of collagen and elastin. Conventional chemical decellularization methods often risk damaging this micro-architecture. Juveàcell applies a proprietary Supercritical Carbon Dioxide (CO₂) process that effectively eliminates immunogenic factors while preserving the native ECM intact. This substantially minimizes foreign body reactions and chronic inflammation while maximizing biocompatibility and long-term skin quality enhancement."

Q. From a plastic surgery specialist's perspective, which patient profiles benefit most from Juveàcell? "It serves as an excellent solution for patients with thin, compromised skin prone to fine wrinkles, or those who found previous skin boosters lacking in hydration longevity. In delicate regions such as around the eyes or mouth, Juveàcell densifies and strengthens the skin layer naturally without unnatural volumization. It is also highly effective for individuals addressing loss of pore elasticity or persistent texture degradation."

Q. What is your outlook on the future of the anti-aging and aesthetic market? "The market will transition toward multi-dimensional reconstruction of the entire skin environment using highly biocompatible bio-materials. The introduction of Juveàcell marks an important turning point for hADM-based aesthetic solutions. However, achieving optimal results requires precise diagnosis of skin thickness and anatomical characteristics, combined with meticulous injection techniques by experienced specialists."
