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.

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。
伤口的愈合除了需要良好的环境以外,必不可少的就是需要充足的营养物质的提供。今天小编就给大家介绍一下与伤口愈合紧密相关的一些营养素(分为两次课程)。
