Topical application of 17β-estradiol (E2) has been shown to improve various hallmark features skin aging, including enhancing elasticity and hydration, reducing wrinkles, promoting collagen synthesis. However, the role estrogen in UVB-induced photoaging remains unclear. Furthermore, E2's clinical is limited by issues such as bioavailability potential adverse effects. Therefore, this study aims explore E2 prepare a gold (Au)@mesoporous polydopamine (mPDA)-hyaluronic acid (HA)/carboxymethyl chitosan (CMCS) nanoparticle composite hydrogel (Au/E2@mPDA-HCG) for treatment photoaging. This successfully fabricated mPDA with well-defined mesoporous structure incorporated Au NPs into mesopores using an situ growth method, thereby constructing Au@mPDA loaded E2. Subsequently, Au/E2@mPDA were embedded HA/CMCS develop Au/E2@mPDA-HCG hydrogel. The was characterized through vitro vivo experiments, its efficacy improving evaluated. revealed that deficiency significantly exacerbates photoaging, likely mechanisms closely associated increased oxidative stress reduced production. Moreover, demonstrated favorable morphological characteristics biocompatibility. In experimental results indicated effectively enhanced therapeutic treating evidenced significant mitigation inflammatory responses, along promotion conclusion, suggests combination Au@mPDA@HCG nanocomposite offers promising strategy

The depletion of the ozone layer has intensified ultraviolet (UV) radiation exposure, leading to oxidative stress, DNA damage, inflammation, photoaging, and skin cancer. Medicinal plants, widely used in Traditional Herbal Medicine (THM), particularly Chinese (TCM), have demonstrated significant therapeutic potential due their well-characterized active compounds established photoprotective effects. This review systematically evaluates 18 medicinal plants selected based on traditional use skin-related conditions emerging evidence supporting efficacy against UV-induced damage. Their bioactive components exert antioxidant, anti-inflammatory, repair, depigmentation effects by modulating key signaling pathways, including Nrf2/ARE-, MAPK/AP-1-, PI3K/Akt-, MITF/TYR-related melanogenesis pathways. Moreover, novel drug delivery systems, such as exosomes, hydrogels, nanoemulsions, significantly enhanced stability, bioavailability, penetration these compounds. However, challenges remain standardizing plant-derived formulations, elucidating complex synergistic mechanisms, translating preclinical findings into clinical applications. Future interdisciplinary research technological advancements will be essential harness full for damage prevention treatment.
