BIS-DEMETHOXYCURCUMIN.

Valuable CAS 33171-05-0 / ANTIOXIDANT

A high-stability curcuminoid derivative engineered for superior skin penetration and multi-pathway biological activity. This precision molecule outperforms standard turmeric extracts by providing intensive anti-inflammatory and antibacterial benefits without the typical stability issues of parent curcumin.

antioxidant anti-inflammatory antibacterial skin-brightening soothing agent

Science

It modulates the skin's inflammatory response by inhibiting NF-κB and MAPK signaling pathways, effectively dampening the production of pro-inflammatory cytokines like TNF-α and IL-6. Simultaneously, it triggers the Nrf2/HO-1 pathway to reinforce the dermis's natural antioxidant shield and acts as a tyrosinase inhibitor to regulate melanin production and brighten the complexion.
