Abstract: This comprehensive review explores the pivotal roles of glycation and oxidative stress in the aging process of the skin, their targeted therapeutic applications in aesthetic and regenerative medicine, as well as anti-aging interventions. Glycation, a biochemical process involving the non-enzymatic attachment of sugars to proteins, lipids, or nucleic acids, culminates in the formation of Advanced Glycation End products (AGEs). These AGEs are significant contributors to aging and various chronic ailments, triggering oxidative stress and inflammatory pathways, thereby manifesting as wrinkles, diminished skin elasticity, and other age-related dermal alterations. A central focus of this review is the synergistic interplay between Hyaluronic Acid (HA) and Trehalose in combating these aging mechanisms. HA, renowned for its anti-inflammatory and antioxidative properties, assumes a pivotal role in modulating Reactive Oxygen Species (ROS) levels and safeguarding against oxidative damage. Concurrently, trehalose targetsglycation and oxidative stress, exhibiting promising outcomes in augmenting skin health, providing Ultraviolet B (UVB) photoprotection, and manifesting notable anti-photoaging effects. The combined administration of HA and trehalose not only addresses existing skin damage but also confers preventive and reparative benefits, particularly in stabilizing HA and mitigating glycation-induced stress. Their synergistic action significantly enhances skin quality and mitigates inflammation. The implications of these findings are profound for the future of anti-aging therapeutics in aesthetic medicine, suggesting that the integration of HA and trehalose holds promise for revolutionary advancements in preserving skin vitality and health. Moreover this paper underscores the imperative for continued research into the combined efficacy of these compounds, advocating for innovative therapeutic modalities in aesthetic medicine and enhanced strategies for combating aging, glycation, and oxidative stress.

Abstract
Longevity genes and senescence-related signaling proteins are crucial targets in aging research, which aims to enhance the healthy period and quality of life. Identifying these target proteins remains challenging because of the need for precise categorization and validation methods. Our multifaceted approach combined bioinformatics with transcriptomic data to identify collagen as a key element associated with the lifespan of the model organism, Caenorhabditis elegans. By analyzing transcriptomic data from long-lived mutants that involved mechanisms such as antioxidation, dietary restriction, and genetic background, we identified collagen as a common longevity-associated gene. We validated these findings by confirming that collagen peptides positively affect lifespan, thereby strengthening the validity of the target. Further verification through healthspan factors in C. elegans and functional assays in skin fibroblasts provided additional evidence of the role of collagen in organismal aging. Specifically, our study revealed that collagen type VII is a significant target protein for mitigating age-related decline. By validating these findings across different aging models and cell-based studies, we present compelling evidence for the anti-aging effects of collagen type VII, highlighting its potential as a target for promoting healthy aging. This study proposes that collagen not only serves as an indicative marker of organismal longevity across various senescence-related signaling pathways, but also offers a mechanistic understanding of skin degeneration. Consequently, collagen is an effective target for interventions aimed at mitigating skin aging. This study underscores the potential of collagen type VII (bonding collagen T7) as a therapeutic target for enhancing skin health and overall longevity.

你知道吗，皮肤是人体最重要的系统之一。我们应该定期呵护她。想要呵护我们的皮肤，就要了解它，今天小编给大家介绍一下，我们人体中面积最大的系统—皮肤的结构。
不管哪种肤质，哪怕是“天生丽质”的人，都会存在或多或少的小毛病，每种不同的肤质可能出现的问题也各有侧重，当皮肤出现问题时就应该警醒了，应该立即审视和调整你的计划，那么我们应该如何科学评估自己的皮肤？今天小编就告诉大家医生及伤口师是如何评估我们的皮肤的。
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。
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。
