Glabridin is a kind of flavonoids.It is known as “whitening gold” because of its powerful whitening effect. Glabridin can effectively inhibit tyrosinase activity, thereby inhibiting the production of melanin. It is a safe, mild as well as effective whitening active ingredient. Experimental data show that the whitening effect of Glabridin is 232 times that of vitamin C, 16 times that of hydroquinone, and 1164 times that of arbutin.  Glabridin, also known as licorice flavonoids, is a safe, mild and super skin-whitening ingredient. The content of Glabridin only accounts for 0.1%-0.3% of of Glycyrrhiza glabra. 1000KG Glycyrrhiza glabra can only extract 100g Glabridin. Therefore, Glabridin is so scarce and precious, and it is almost the same as the price of gold.     Key Technical Parameters: Appearance White powder Purity （HPLC） Glabridin≥98% Test of flavone Positive Physical characteristics Particle-size NLT100% 80 Mesh Loss on drying ≤2.0% Heavy metal Total metals ≤10.0ppm Arsenic ≤2.0ppm Lead ≤2.0ppm Mercury ≤1.0ppm Cadmium ≤0.5 ppm Microorganism Total number of bacteria ≤100cfu/g Yeast ≤100cfu/g Escherichia coli Not included Salmonella Not included Staphylococcus Not included Function: 1. Glabridin can whiten and inhibit melanin. 2. Glabridin has anti-inflammatory effects. 3. Glabridin has antioxidant effect. 4. Glabridin can effectively resist bacteria   Application: 1.Glabridin has depigmentation and properties. It inhibits the production of melanin, the pigment responsible for the colouring of the skin; 2.Studies have show positive effects in fields like LDL(low-density lipoprotein ) protection against oxidation; 3.Glabridin inhibits the inflammatory reaction by blocking cyclooxygenase and preventing the formation of free radicals such as superoxide anions; 4.At the same time Glabridin prevent rough skin and also has anti-inflammatory, antibacterial effect;
