Turmeric Extract
Contains curcuminoids with antioxidant and anti-inflammatory benefits for skin.
What does Turmeric Extract do for skin?
Turmeric extract, rich in curcuminoids, exerts its effects primarily through antioxidant and anti-inflammatory pathways. It scavenges reactive oxygen species (ROS) and upregulates endogenous antioxidant enzymes, protecting skin cells from oxidative damage caused by UV radiation and environmental pollutants. Furthermore, it inhibits key pro-inflammatory mediators such as NF-κB, COX-2, and various cytokines, reducing redness, swelling, and irritation. Topically, it also shows potential in inhibiting tyrosinase activity, thereby contributing to skin brightening and reducing hyperpigmentation.
Typical concentration: 0.1-3% (most formulas use 0.5-1%).
Is Turmeric Extract safe?
Generally considered safe for topical use, with a low incidence of irritation or sensitization. The CIR Expert Panel has not specifically reviewed Turmeric Extract, but components like Curcuma Longa Root Extract are generally regarded as safe. Note its yellow pigment may temporarily stain skin or textiles.
