Summary

Skin-conditioning Antioxidant Brightening Anti-inflammatory Hydrating Anti-aging Photo-protective Skin renewal

Science

Mechanism of Action

The ingredient functions as a skin-brightening agent by inhibiting tyrosinase, an enzyme crucial for melanin synthesis. It acts as a potent antioxidant, utilizing components like carotenoids, coumarins, limonoids, and flavonoids to protect against UV-induced damage and neutralize free radicals. Its anti-inflammatory properties stem from its ability to suppress inflammatory mediators such as nitric oxide, TNF-α, IL-6, and PGE2. Furthermore, it enhances skin hydration by stimulating the production of hyaluronic acid and promoting the expression of key barrier proteins like filaggrin and serine palmitoyltransferase (SPT), while also supporting skin regeneration and accelerated cellular renewal.
