Purpose: The study aimed to investigate in vitro anti-aging activities of 29 Dendrobium spp. and develop and characterize microemulsions (MEs) for topical application.
Methods: Antioxidant activity was determined using 2,2-diphenyl-1-picrylhydrazyl (DPPH), H2O2 scavenging, and ferric reducing antioxidant power (FRAP) assays. The anti-collagenase (MMP-1 and MMP-2) and anti-elastase activities were also evaluated.
Cytotoxicity and human intracellular reactive oxygen species (ROS) levels were determined using resazurin reduction and 2′,7′- dichlorofluorescin diacetate (DCFDA) assays, respectively. D. kentrophyllum extract-loaded microemulsion (DKME) was then prepared and optimized. The stability of DKME was studied using a heating-cooling cycle.
Results: D. kentrophyllum appeared to be the best candidate anti-aging agent because of its antioxidant, anti-collagenase, and antielastase activities. The extract was safe for human skin cells at a concentration of 6.25–100 μg/mL. It also decreased the intracellular ROS-induced ultraviolet B (UVB) irradiation compared to that in the control. DKME comprising Tween 80:ethanol (5:1), water, and isononyl isononanoate showed a suitable appearance, droplet size, polydisperse index, zeta potential, pH, and viscosity. This formulation demonstrated desirable physical and chemical stability, with non-cytotoxic effects.
Conclusion: DKME is considered a promising anti-aging product. However, an in vivo study of this optimized formulation might be evaluated in further study for anti-aging purposes.

Abstract: Isoflavones are found in numerous plant species within the Leguminosae family; however, soy isoflavones are particularly significant in practice and have been extensively studied in recent years. The health-promoting potential of orally administered soy isoflavones is widely documented in the scientific literature, and many review articles have been developed to highlight their significance. However, it should be noted that soy-isoflavone-rich extracts and isolated soy isoflavones, such as genistein and daidzein, are also often applied topically as ingredients in many formulations, including face creams, tonics, and emulsions. New delivery systems are continuously being developed to enhance the skin permeability of isoflavones, thus improving their efficacy. In this context, their direct activity on skin cells is an important aspect of scientific research. The anti-inflammatory, protective, and antioxidant properties of isoflavones and soy extracts make them promising cosmetic ingredients with anti-aging potential because inflammation and the accumulation of reactive oxygen species (ROS) can lead to structural and functional changes in skin cells, accelerating the aging process. This review provides an overview of research on the impact of the application of soy isoflavone extract and soy-derived isoflavones on skin cells, with a focus on the documented molecular mechanisms underlying their effects. This study aims to offer essential insights to aid in the development of functional cosmetics and future clinical applications.

疤痕形成的原因
在人体损伤后愈合的部位，皮肤上会留下不规则的凸起于表面，质硬的，或伴有疼痛、红、痒等不具备正常皮肤组织结构及生理功能的，失去正常组织活力的，异常的，不健全的组织即称为疤痕。疤痕是皮肤对创伤自我修复的产物。
当一个人受伤后，尤其是大面积烧烫伤后，受伤区域的疤痕可能会出现凸起并伴随瘙痒。
严重的瘙痒可以让病人寝食不安，痛苦不堪。那么，疤痕为什么会痒?可以治疗吗?
