Intrinsic and extrinsic factors, including lifestyle and sun exposure, can contribute to cell senescence, which impairs skin homeostasis, that may in turn lead to skin aging. Senescent cells have a specific secretome, called the senescence-associated secretory phenotype (SASP) that includes MMPs, CXCLs and S100A8/9. Reducing the SASP with senotherapeutics is a promising strategy to reduce skin aging. Here we evaluated the effect of a formula containing niacinamide and hyaluronic acid, which are known to limit senescence and skin aging. We conducted three different studies. (1) Ex vivo explants treated with the formula had more collagen and glycosaminoglycan. (2) In a clinical trial with forty-four women, two months of treatment improved fne lines, wrinkles, luminosity, smoothness, homogeneity, and plumpness. (3) In a third study on thirty women, we treated one arm for two months and took skin biopsies to study gene expression. 101 mRNAs and 13 miRNAs were differentially expressed. We observed a likely senomorphic efect, as there was a decrease in many SASP genes including MMP12 and CXCL9 and a significant downregulation of autocrine signaling genes: S100A8 and S100A9. These pharmaco-clinical results are the first to demonstrate the senomorphic properties of an effective anti-aging formula in skin.

Abstract
Phytochemicals help mitigate skin aging by scavenging free radicals, modulating key enzymatic pathways, and promoting the skin’s structural integrity. Carotenoids, vitamins, essential fatty acids, and phenolic compounds work by acting as antioxidants, inhibiting enzymes like hyaluronidase, collagenase, and elastase, which degrade skin structure, and reducing levels of inflammatory markers (IL-6, IL-8, etc.) and matrix metalloproteinases (MMP-1, MMP- 2) linked to aging. Recent research highlights that plant-based phytochemicals can improve skin elasticity, reduce hyperpigmentation, prevent the breakdown of important skin proteins, and support wound healing, making them valuable components for skin care and treatments. This review explores the multifaceted roles of phytochemicals in maintaining and improving skin health, highlighting their mechanisms of action and potential in skin anti-aging

糖尿病足是糖尿病最常见的并发症之一，糖尿病患者一生中患足溃疡的风险为10%至25%。糖尿病足感染容易扩散，尤其是深部组织感染，可促进溃疡发展。如果不及时治疗，很可能造成截肢等后果
对于下肢溃疡这个疾病，我们已经在之前介绍过一些了，那么想要更深入的了解及治疗这个疾病，就需要完善的检查还有评估，今天我们来介绍一下，关伊下肢溃疡都需要哪些专业的检查和评估呢？
