Science

Mechanism of Action

This ingredient operates through several precise mechanisms: it robustly scavenges free radicals via its rich content of vitamin C, flavonoids, and polyphenols, thereby protecting against environmental damage. Its anti-inflammatory action is evidenced by a 43.2% reduction in PGE2 levels in LPS-stimulated macrophages and inhibition of TNF-α-induced reactive oxygen species (ROS) in dermal fibroblasts. Furthermore, it contributes to anti-aging by protecting collagen via reduced MMP-1 secretion and upregulated procollagen type I α1 expression. It also fortifies the skin barrier by promoting keratinocyte differentiation and increasing key components like FLG, IVL, LOR, and CLDN1, while offering hydrating, potential skin brightening, and mild astringent benefits.
