Science
Mechanism of Action
At a cellular level, Defatted Narcissus Tazetta Flower extract inhibits the mechanistic target of rapamycin complex 1 (mTORC1) pathway, a critical regulator of cellular senescence, thereby preserving telomere integrity and extending the lifespan of dermal fibroblasts. Its rich polyphenolic profile confers potent antioxidant capacity, shielding skin cells from reactive oxygen species (ROS)-induced oxidative damage. Phenylethanoid compounds present within the extract effectively inhibit tyrosinase activity, thereby regulating melanogenesis and addressing hyperpigmentation disorders. Furthermore, it exhibits sebostatic properties, contributing to sebum production regulation, and provides anti-inflammatory effects through its alkaloid constituents, notably lycorine derivatives. The ingredient also acts as an astringent to refine pore appearance and actively promotes dermal fibroblast proliferation for enhanced skin structure.
