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

皮肤是作为人类健康与美丽的象征,当我们最初注意到一个人时,她健康的肌肤往往是形成美好的第一印象的重要因素。
健康与美丽是分不开的,尤其是对皮肤来说,这一点更加重要,如果没有了健康,便根本谈不上皮肤的美丽。
在日常的工作、学习、生活中,难免会有磕磕碰碰,时不时我们的身体就是因某些原因,造成不可避免的伤口出现。有时我们会发现,有些伤口会快速愈合甚至不留痕迹,而有些伤口经久不愈甚至情况愈演愈烈,造成不可挽回的后果,只有我们能够简单的初步认识伤口的各种情况,才能更好地对待我们所发生的一些伤口情况,使其快速愈合,让我们的身体恢复健康。
今天,小编就给大家讲解一下什么是伤口以及伤口的分类。
在日常生活中,当我们的机体受到伤害而造成伤口的时候,最希望伤口能够尽快愈合,恢复到未受伤时候的状态。通过观察不难发现,伤口几乎是一天一个样,那么机体是如何让伤口产生这些变化的呢?伤口有时如何进行修复的呢?
今天小编就告诉大家伤口的愈合过程,通过了解这个过程,我们能够更好地了解自己伤口所处在的周期,以及能够大概了解伤口是往好的方向发展还是往坏的方向恶化。话不多说,下面介绍今天的主题!
一旦有伤口出现,往往会有疼痛的症状发生,这些疼痛反复发作,让许多患者困扰不已。实际上导致患者出现伤口疼痛有些是伤口愈合期间的正常症状,有些由于伤口感染等原因导致,我们应该区别对待,区别处理。
伤口世界平台生态圈,以“关爱人间所有伤口患者”为愿景,连接、整合和拓展线上和线下的管理慢性伤口的资源,倡导远程、就近和居家管理慢性伤口,解决伤口专家的碎片化时间的价值创造、诊疗经验的裂变复制、和患者的就近、居家和低成本管理慢性伤口的问题。
