Science
Mechanism of Action
This ingredient operates by significantly increasing the scavenging activity against DPPH radicals, thereby providing robust antioxidant defense. It also actively inhibits Matrix Metalloproteinase-1 (MMP-1) expression and promotes the production of type I procollagen, contributing to improved skin elasticity and reduced appearance of wrinkles.
