Abstract

Background: The delicate periorbital region is susceptible to skin dehydration, wrinkles, and loss of elasticity. Thus, targeted and effective anti-aging interventions are necessary for the periorbital area.

Aim: To evaluate the efficacy and safety of a new anti-aging eye cream formulated with the active complex (Yeast/rice fermentation filtrate, N-acetylneuraminic acid, palmityl tripeptide-1, and palmitoyl tetrapeptide-7).

Methods: The cell viability and expressions of key extracellular matrix (ECM) components of the active complex were evaluated using a human skin fibroblast model. In the 12-week clinical trial, skin hydration, elasticity, facial photographs, and collagen density following eye cream application were assessed using Corneometer, Cutometer, VISIA, and ultrasound device, respectively. Dermatologists and participants evaluated clinical efficacy and safety at baseline, and after 4, 8, and 12 weeks.

Results: PCR and immunofluorescent analyses revealed that the active complex significantly stimulated fibroblast proliferation (p < 0.05) and markedly promote the synthesis of collagen and elastin. Clinical findings exhibited a substantial enhancement in skin hydration (28.12%), elasticity (18.81%), and collagen production (54.99%) following 12 weeks of eye cream application. Dermatological evaluations and participants’ assessments reported a significant improvement in skin moisture, roughness, elasticity, as well as fine lines and wrinkles by week 8.

Conclusion: The new anti-aging eye cream, enriched with the active complex, demonstrates comprehensive rejuvenating effects, effectively addressing aging concerns in the periorbital area, coupled with a high safety profile.

Abstract

Facial aging prompts a shift in the demands for lifting procedures, transitioning from targeted improvements in younger individuals to overall facial contour enhancements as skin elasticity declines in later years. This paper examines the evolution of PDO volumizing threads, delineating their development from initial limitations to contemporary innovations aimed at addressing tissue deformation and maintaining thread integrity post-insertion. Categorizing these threads based on elasticity, shape, and functionality underscores their versatility and application nuances, catering to specific wrinkle correction, contour sculpting, and facial volume restoration. The discussion emphasizes the pivotal role of thread characteristics in achieving optimal outcomes while minimizing potential complications. By delving into historical contexts, mechanisms, effectiveness, and thread classification, this paper equips practitioners with a comprehensive understanding to make informed decisions in selecting threads for volumizing thread procedures. Recommendations for future research directions, including longterm safety assessments and patient-specific outcomes, seek to enhance the clinical utility and applicability of this analysis.

Abstract

Background: During aging, the face loses volume with progressive sagging of the soft tissues, while the neck demonstrates skin laxity and muscle banding. The treatment of facial and neck aging usually involves a traditional facelift, which can cause noticeable scarring and distortion of anatomy.

Objectives: Modern facelift surgery must avoid such shortcomings and still address aging in all layers of the face. To achieve this goal a novel surgical technique was developed and coined the “ponytail lift” (PTL). When global facial rejuvenation is indicated, this procedure is combined with neck skin excision and referred to as the “ponytail facelift” (PTFL).

Methods: A retrospective analysis of 600 consecutive cases over 22 years (2000-2022) of facial rejuvenation employing the endoscopic techniques of PTL and PTFL was performed. Patients were followed for at least 12 months postoperatively. Demographics, surgical data, and complications were recorded and analyzed. Additionally, technical details of the PTL and PTFL are discussed.

Results: There were no instances of postoperative skin flap necrosis, and no permanent nerve injuries were recorded. An additional surgical touch-up procedure to address unsatisfied aesthetic needs was performed in 20 cases.

Conclusions: The ponytail procedures offer a stepwise approach matched to the extent of the problem and are intended to refresh or transform the face with minimal incisions. The procedures represent a deep plane facelift without the scar burden, with incisions that are hidden in the temple, postauricular, and posterior scalp. The described techniques are safe and effective while providing reliable and satisfying results.

摘要

背景: 随着年龄的增长，面部体积会逐渐减小，软组织会逐渐下垂，而颈部会出现皮肤松弛和肌肉带状。面部和颈部衰老的治疗通常涉及传统的面部拉皮术，这会导致明显的疤痕和解剖结构扭曲。

目标: 现代面部拉皮手术必须避免此类缺点，同时还要解决面部所有层面的衰老问题。为了实现这一目标，开发了一种新颖的手术技术，创造了“马尾辫提升术”（PTL）这一名称。当需要进行整体面部年轻化时，该手术与颈部皮肤切除术相结合，称为“马尾辫拉皮术”（PTFL）。

方法: 回顾性分析了 22 年间（2000-2022 年）采用 PTL 和 PTFL 内窥镜技术进行面部年轻化的 600 个连续病例。术后对患者进行至少 12 个月的随访。记录并分析了人口统计学、手术数据和并发症。此外，还讨论了 PTL 和 PTFL 的技术细节。

结果: 没有出现术后皮瓣坏死的情况，也没有记录到永久性神经损伤。在 20 个病例中进行了额外的外科修补手术，以解决未满足的美学需求。

结论: 马尾辫手术提供了一种与问题程度相匹配的分步方法，旨在以最小的切口使面部得以改造或焕然一新。这些手术代表了一种深层平面拉皮术，没有疤痕负担，切口隐藏在太阳穴、耳后和头皮后部。所描述的技术是安全有效的，同时提供可靠且令人满意的结果。

Abstract: Background: The aim of this study was to evaluate the moisturizing efficacy of quince fruit, used in folk medicine. For this purpose, the phytoconstituents of Cydonia oblonga fruit extract, like phenolics and flavonoids, were determined. A stable cosmetic emulgel containing 4% Cydonia oblonga fresh fruit extract was formulated and subjected to in vivo evaluation compared with a control. Materials and Methods: Cydonia oblonga fresh fruit extract was evaluated for tyrosinase activity and phenolic and flavonoid content. A stable emulgel containing 4% Cydonia oblonga fresh fruit extract was formulated and tested in a skin irritation test. After this, in vivo tests of erythema, moisture, sebum, and skin elasticity were conducted. The in vivo evaluation was a randomized and single-blind study. Thirteen healthy female volunteers were selected for a three-month study period. Results: Cydonia oblonga fruit extract showed good phenolic and flavonoid content, which was associated with its good antioxidant and tyrosinase-inhibiting activity. Cydonia oblonga containing the emulgel showed a reduction in sebum and erythema, while the elasticity and moisture content showed increments in their levels after the three-month application of the formulation. The fruit contains chlorogenic acid and many sugars, which might account for its anti-inflammatory and sebum reduction effects; it is also capable of enhancing the skin’s hydration level and decreasing skin sagging by enhancing its elasticity. Conclusion: The emulgel loaded with Cydonia oblonga fresh fruit extract is verified regarding its folklore status as a moisturizing agent that enhances the facial skin cells’ resilience potential.
