PRUNUS YEDOENSIS SPROUT CELL EXTRACT.

This extract operates through multiple pathways to improve skin health. It exhibits strong antioxidant activity by significantly reducing reactive oxygen species (ROS) and malondialdehyde (MDA), while boosting intrinsic antioxidant enzymes such as superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px). Its rich profile of polyphenols, flavonoids, and phenolic acids directly neutralizes free radicals, mitigating oxidative stress. The extract also demonstrates anti-inflammatory effects by decreasing nitric oxide (NO) production and modulating key inflammatory mediators, including interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α), potentially via NF-KB and MAPK signaling pathways. Furthermore, it supports skin barrier integrity and hydration through increased hyaluronic acid (HA) synthesis and enhanced expression of epidermal barrier proteins (filaggrin and involucrin). Initial indications suggest it may also stimulate collagen production, reduce the appearance of fine lines, and contribute to skin brightening by inhibiting tyrosinase activity.
