LYCOPUS COREANUS LEAF EXTRACT.

This extract precisely targets cellular signaling pathways implicated in skin sensitivity and inflammation. It significantly improves NF-κB activation markers by approximately 50% and reduces MAPK activation markers by 40%, effectively diminishing the secretion of inflammatory substances and mitigating the initial cascade of sensitivity. Its action stabilizes the skin barrier and cellular responses, allowing for deep dermal penetration to facilitate tissue repair and reduce inflammation. Furthermore, it exerts inhibitory effects on tyrosinase activity to reduce hyperpigmentation, inhibits lipoxygenase activity to regulate sebum production (beneficial for oily skin), and suppresses MMP-1 activity to minimize the appearance of fine lines, wrinkles, and sagging. It also provides robust antioxidant defense, inhibits the infiltration of mast cells, eosinophils, and CD8+ cells, and suppresses the expression of IgE and IL‑6, while downregulating inflammatory chemokines and cytokines via inhibition of ERK, JNK, and NF‑κB phosphorylation.
