Science
Mechanism of Action
Enhances skin barrier function by upregulating key differentiation markers including involucrin, transglutaminase-1, and filaggrin in keratinocytes. Simultaneously suppresses inflammatory cascades by blocking pro-inflammatory cytokines (TSLP, IL-4, IL-5, IL-13) and matrix-degrading enzymes (MMP-1, MMP-3) through p38 and JNK-AP-1 pathway modulation. Additionally inhibits melanin synthesis by downregulating MITF protein and tyrosinase enzyme activity.
