Luteolin Mitigates Photoaging Caused by UVA-Induced Fibroblast Senescence by Modulating Oxidative Stress Pathways

International Journal of Molecular Sciences
As a polyphenolic plant flavone, luteolin (Lut) is widely found in many medicinal plants, flowers, and vegetables. Although Lut has been shown to have the effect of preventing and treating skin photoaging, its role in preventing photoaging specifically ...

Human adipose and umbilical cord mesenchymal stem cell-derived extracellular vesicles mitigate photoaging via TIMP1/Notch1

Signal Transduction and Targeted Therapy
UVB radiation induces oxidative stress, DNA damage, and inflammation, leading to skin wrinkling, compromised barrier function, and an increased risk of carcinogenesis. Addressing or preventing photoaging may offer a promising therapeutic avenue for these

Photoaging

Postgraduate Medicine, 1993
Given the many ways our culture promotes deeply tanned skin as a symbol of beauty, health, and even happiness, physicians face an uphill battle in promoting the healthy aspects of a pale complexion. Not only can excessive solar exposure accelerate and intensify aging in skin, it can also lead to serious health risks.

Functional hyaluronic acid microneedles for skin photoaging based on collagen induction and oxidative stress regulation strategies.

International Journal of Biological Macromolecules
Photoaging holds remarkable importance for skin health and senescence. Ultraviolet (UV) irradiation results in the disruption of the extracellular matrix (ECM) microenvironment, the degradation of collagen, and the generation of oxidative stress ...
