Cosmetic Grade Curcumin Overview
Curcumin is derived from the rhizome of Curcuma longa, also known as turmeric. Curcumin has a variety of biological activities. It is a functional cosmetic raw material with excellent performance and a wide range of uses. Curcumin is poorly water-soluble and unstable, which limits its application in cosmetics. After upgrades of process, We have developed water-soluble curcumin. It is of cosmetics grade; it has higher bioavailability and greater skin penetration. Moreover, cosmetics grade curcumin has anti-aging and anti-wrinkles properties, as well as skin-whitening effect. It is an effective cosmetic ingredient for skincare.

Cosmetic Grade Curcumin Benefits
1.Anti-aging and Sun ProtectionCurcumin's molecular structure contains a diketone structure, which is a high-level conjugated planar molecule, and is a rare natural pigment with β-diketone structure in nature. Additionally, curcumin has abilities to resist oxidation, scavenge free radicals, and absorb ultraviolet rays. Therefore, curcumin is a natural cosmetic ingredient for anti-aging and sun protection.2.Skin WhiteningCurcumin contains a polyphenol structure, and its skin whitening effect is the same as that of other plant polyphenols. Therefore, it can greatly inhibit tyrosinase, and reduce its activity. Also curcumin's strong antioxidant capacity and the ability to capture free radicals are the main basis for its whitening effect.
