Carotenoids in Skin Photoaging: Unveiling Protective Effects, Molecular Insights, and Safety and Bioavailability Frontiers

Antioxidants
Skin photoaging, driven primarily by ultraviolet radiation, remains a critical dermatological concern. Carotenoids, a class of natural pigments with potent antioxidant properties, have emerged as promising agents for preventing and mitigating photoaging.

Hesperidin from Chenpi Ameliorates Skin Photoaging by Targeting HSPA1L to Stabilize GPX4 and Suppress Ferroptosis [PDF]

Antioxidants
Photoaging is an extrinsic skin aging process caused by chronic ultraviolet (UV) radiation. A core pathological feature of photoaging is excessive oxidative stress, which can further induce ferroptosis.

Non-Negligible Effects of UV Irradiation on Transformation and Environmental Risks of Microplastics in the Water Environment

Journal of Xenobiotics, 2021
Microplastics (MPs) are ubiquitous in environmental media, and their harmful effects on MPs on the ecosystem have attracted more and more attention. Once released into the environment, MPs can trigger oxidative degradation through ultraviolet (UV) to ...

The Secretome Derived From Human Umbilical Cord Mesenchymal Stem Cells Improves Skin Photoaging by Enhancing Mitophagy to Inhibit the cGAS-STING Pathway. [PDF]

Aging Cell
HUC‐MSC‐derived SCT alleviates UV‐induced skin photoaging. It acts by enhancing mitophagy to clear damaged mitochondria, thereby suppressing the pro‐inflammatory cGAS‐STING pathway. This work identifies SCT as a novel cell‐free therapy targeting mitochondrial quality control to counteract sterile inflammation in aging. ABSTRACT Ultraviolet (UV)‐induced

Roles of oxidative stress in photoaging and the pathogenesis of systemic sclerosis [PDF]

, 2006
我々の皮膚は常に外界からの様々な刺激にさらされている．その刺激の代表的なものとして太陽光線中の紫外線があげられる．紫外線は皮膚癌の発生の誘因となる他に，紫外線の曝露により皮膚には光老化と称される変化が生じてくる．光老化の特徴的な変化として皮膚表面のびまん性の色素沈着と深い皺があげられるが，その変化を特徴づけるものとして皮膚真皮におけるsolar elastosisと称される膠原線維・弾性線維の変化がある．この皮膚光老化には紫外線による酸化ストレスが深く関与していると考えられている．一方 ...
