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.

一位援疆医生讲述了自己的故事:一天夜里,他接诊了一名遭遇车祸的病人,肝脏破裂,生命垂危。虽经全力抢救,病人终因失血过多而死亡。当医生告诉家属这个坏消息后,家属不仅没有责怪医生,反而向医生道谢,然后要求把切下的破碎肝脏带回去,和死者一起埋葬。丧事办完后,家属又来到医院结清所有费用。此举令这位医生十分感动。从此,每当遇到危重患者,他都没有后顾之忧,总是愿意冒险一搏。
