This study investigated the photoprotective properties of Brazilian pepper tree extract against UV-induced damage in skin cells, reporting that it enhanced expression of genes relevant to skin health and showed superior activity compared to standard antioxidants.

This review explores how various skin cell types contribute to photoaging driven by UV radiation, detailing their interactions and molecular mechanisms like oxidative stress and ECM degradation, ultimately offering insights for future anti-photoaging strategies.

In this laboratory study, researchers reported that Camellia sinensis seed flavonoids significantly reduced oxidative stress and inflammation in UV-irradiated skin cells by modulating key signaling pathways, highlighting its potential as a skincare ingredient for anti-inflammatory and anti-photoaging benefits.

This article discusses the genomic and postgenomic changes in chronic degenerative diseases and cardiovascular and skin disease contexts, highlighting potential modulation through diet and pharmacological interventions without presenting new experimental results.

In this study, treatment with cell-derived nanovesicles from hair follicle mesenchymal stem cells improved photoaging signs in UVB-exposed mice and human dermal fibroblasts by reducing oxidative stress, enhancing cell proliferation, and promoting extracellular matrix production.
