Science
Mechanism of Action
This ingredient functions as a high-performance humectant and antioxidant complex. It utilizes a rich profile of amino acids (citrulline and arginine) to maintain osmotic pressure within skin cells, while its concentration of lycopene and Vitamins A, C, and E neutralizes free radicals. It further supports the skin's structural integrity by promoting collagen synthesis and modulating sebum production for a refined texture.
