FISETIN.

Fisetin operates through several distinct pathways to enhance skin health. It acts as a potent antioxidant, neutralizing free radicals generated by environmental stressors like UV radiation and pollution, thereby mitigating oxidative stress. Its anti-inflammatory properties are demonstrated by its ability to inhibit pro-inflammatory molecules (e.g., NF-κB) and suppress senescence-associated secretory phenotypes (SASP) cytokines, effectively soothing irritated skin and reducing redness. As a groundbreaking senolytic agent, Fisetin selectively eliminates senescent ('zombie') dermal fibroblasts without harming healthy cells, directly promoting skin rejuvenation. Furthermore, Fisetin stimulates collagen production and inhibits collagenase and elastase, enzymes responsible for degrading collagen and elastin, leading to improved skin elasticity and firmness. It also contributes to a more even skin tone by inhibiting tyrosinase, a key enzyme in melanin synthesis. Additional benefits include enhanced skin barrier function for improved hydration and accelerated wound healing through cellular repair and inflammation reduction.
