Science
Mechanism of Action
Smilax China extracts exert their beneficial effects primarily through antioxidant and anti-inflammatory pathways. They effectively scavenge free radicals, mitigating oxidative stress, and possess immunomodulatory properties by inhibiting pro-inflammatory cytokines such as TNF-α, IL-6, and IL-1β, alongside suppressing NF-κB and MAPK signaling. The extract also demonstrates antimicrobial activity against Cutibacterium acnes, potentially by disrupting bacterial cell membranes. Furthermore, it can inhibit Advanced Glycation End Products (AGEs) formation and aldose reductase activity, contributing to anti-aging benefits, and promotes skin barrier repair and wound healing through enhanced keratinocyte proliferation, migration, collagen synthesis, and upregulation of key barrier proteins like filaggrin and loricrin.
