Product introduction

Inhibition of tyrosinase

Human tyrosinase is an essential enzyme, which can produce melanin regularly and make skin or eyes turn from brown to black. We know that skin exposure to ultraviolet light will cause some reactions (such as inflammation). Because the phospholipid membrane of skin tissue is damaged by reactive oxygen species induced by ultraviolet light, this histological change is manifested as erythema and pigmentation. Reactive oxygen is a substance that can cause skin pigmentation, so inhibiting its production can inhibit the production of melanin. Light glycyrrhizin is the most expensive and effective whitening ingredient among all whitening ingredients. According to the Chinese Herbal Medicine, the whitening effect of light glycyrrhizin is 232 times that of ordinary vitamin C, 16 times higher than hydroquinone, and 1164 times that of "arbutin", so light glycyrrhizin is called "whitening gold".

Anti-inflammatory effect

The anti-inflammatory activity of light glycyrrhizin was verified by experiments. The guinea pigs were irradiated with ultraviolet to cause pigmentation, and then smeared with 0.5% light glycyrrhizin solution. It was found that light glycyrrhizin reduced skin inflammation caused by ultraviolet stimulation. Use a value to indicate erythema on the skin. The degree of inflammation reduction can be calculated by recording the a value (colorimeter reading) of glycyrrhizin before and after irradiation. Researchers have studied the inhibition of cyclooxygenase activity by light glycyrrhizin. Cyclooxygenase is an enzyme that converts arachidonic acid into prostaglandin, which is an inflammatory factor. Compared with the control group (using the current cyclooxygenase inhibitor, indomethacin), light glycyrrhizin can achieve the effect of inhibiting cyclooxygenase. It is worth trusting that glycyrrhizin can reduce inflammation by inhibiting the production of arachidonic acid by inhibiting cyclooxygenase.

Antioxidant effect

Light glycyrrhizin has a strong scavenging effect on free radicals, vitamin C, vitamin E and β- Carotene is recognized as the three kings of antioxidant and anti-aging. Glycyrrhizin is a natural antioxidant with anti-aging ability equivalent to vitamin E. It is reported that its antioxidant effect is significantly better than BHA and BHT. It has been reported that licorice can be used to reduce the corticosteroids of infectious skin diseases and strengthen the role of steroids.

Cosmetics application

Guangglycyrrhizin has excellent anti-inflammatory, antioxidant and anti melanin formation effects, so it is used as a component of various cosmetics and medical care products (such as face cream, lotion, shower gel, etc.). It can be made into whitening face cream, and such patented products have been launched.

Dosage:

In cosmetics, in order to achieve the whitening effect, the patent recommended dosage is 0.001 - 3% of glycyrrhizin, preferably 0.001 - 1%. 1:10 with glycerol, added at low temperature. Glycyrrhizin for external use can inhibit the formation of melanin. It has excellent tyrosinase inhibition activity and can prevent skin sunburn, line spots and sunburn. The recommended dosage is 0.0007-0.05%. Research shows that as long as 0.05% light glycyrrhizin, 0.3% aloe powder, 1% nicotinamide and 1% AA2G are paired, the inhibition rate of melanin tyrosinase is up to 98.97%. For the purpose of inhibiting male hormones and treating acne, the dosage of light glycyrrhizin is 0.01-0.5%.

Chinese scientists have also studied the preparation and application of glycyrrhizin liposomes in cosmetics. The results showed that the liposomes of glycyrrhiza uralensis could be successfully prepared by using the liposome model and preparation technology. The phospholipid bilayer membrane of glycyrrhizin liposome is similar to the biological membrane, which is easy to be fused with the biological membrane, promote the penetration of the effective components to the biological membrane, make the effective components transport across the skin barrier and the biological membrane with high efficiency, and play a positive role in improving and improving its skin whitening and freckle removal effect and other auxiliary effects.
