Glabridin is one of the main flavonoids in the glycyrrhiza.It in cytochrome P450 / NADPH oxidation system shows very strong resistance to free radical oxidation, can obviously inhibit the body produced during the process of metabolism of free radical, against sensitive to oxidation of biological macromolecules (DNA), low density lipoprotein LDL and cell wall by free radicals oxidative damage, etc.In this way, certain pathological changes related to free radical oxidation can be prevented, such as atherosclerosis, cell aging and so on.In addition, the glycyrrhiza has a certain effect of lowering blood lipid and lowering blood pressure.

1. Glabridin has depigmentation and lightening 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.
