HYDRANGEA MACROPHYLLA LEAF EXTRACT.

This extract functions as a potent skin conditioning agent, primarily by establishing an imperceptible moisture barrier through its rich plant polysaccharides, contributing to a fresh and soft dermal surface. Its protective action shields skin against environmental aggressors while boosting cellular regeneration and resistance. The extract's antioxidant capacity combats free radical damage, mitigating signs of aging. Key bioactive constituents, including flavonoids, saponins, and tannins, are integral to maintaining skin elasticity and moisture balance. Notably, Hydrangenol, a significant active component, safeguards cell viability, stimulates procollagen type I production, and inhibits collagen-degrading Matrix Metalloproteinase-1 (MMP-1). Furthermore, it exhibits anti-inflammatory effects by suppressing Akt-mediated NF-κB activation and supports skin moisturization via the AP-1 protein pathway.
