Science
Mechanism of Action
Ardisia japonica extract operates by modulating key inflammatory responses, specifically influencing the PI3K/AKT and MAPK signaling pathways, which includes promoting the phosphorylation of MAPK14, ERK, and JNK proteins. This activity leads to a quantifiable reduction in inflammatory factors such as IL-6 and TNF-α. The extract exhibits significant antioxidant capabilities through direct radical-scavenging. Furthermore, it delivers anti-photoaging and skin-protective actions by preventing UV-induced cellular damage and mortality, bolstering the skin barrier via the upregulation of hyaluronic acid synthase-1, occludin, and transglutaminase-1, mediated by inhibiting the activator protein-1 signaling pathway (ERK and JNK). Research also indicates potential for skin brightening and wrinkle reduction.
