What Is Glabridin ?
Glabridin is a flavonoid extracted from the roots of licorice (Glycyrrhiza glabra) and has a variety of biological activities and health benefits. glabridin is known for its powerful whitening, antioxidant and anti-inflammatory properties and is widely used in skin care and cosmetics.
Glycyrrhiza glabra L. is a perennial herb that grows in southern Europe, Asia, and the Mediterranean region. It is widely planted in Russia, Spain, Iran, and India. The plant of G. glabra is about 1-1.5 meters tall, with small dark green leaves, yellow, blue, and violet flowers, and a sweet rhizome.
Glabridin is one of the main flavonoids in Glycyrrhiza glabra. It shows a strong anti-free radical oxidation effect in the cytochrome P450/NADPH oxidation system, and can significantly inhibit the free radicals produced during the metabolism process in the body to prevent oxidation-sensitive biomacromolecules (low-density lipoprotein LDL, DNA) and cell walls from being damaged by free radical oxidation. This can prevent and treat certain pathological changes related to free radical oxidation, such as atherosclerosis and cell aging. In addition, glabridin has a certain effect of lowering blood lipids and blood pressure. Italian research has also confirmed that Glabridin has an appetite suppressant effect, which can reduce fat without reducing weight. After repeated tests, the main effects are as follows: 1. Whitening, inhibiting melanin; 2. Anti-inflammatory effect; 3. Antioxidant effect; 4. Antibacterial.
