Science
Mechanism of Action
Timosaponin A3 (TA-III) operates by downregulating key markers of skin degradation. It inhibits the increase of matrix metalloproteinase-1 (MMP-1), an enzyme that breaks down collagen, and reduces pro-inflammatory cytokines in skin cells exposed to UVB radiation. Furthermore, TA-III offers photoprotection by suppressing UVB-induced inflammation and DNA damage through the downregulation of DNA repair enzymes like PCNA and SMC1, and by blocking critical signaling pathways such as MAPK, NF-κB, and AP-1. These combined actions establish its anti-inflammatory and antioxidant profile, crucial for limiting wrinkle development.
