Yes, this essence can be used for any skin type, especially for skin with dark yellow skin or many spots. Five core whitening ingredients are added, but they will not turn black. Extracted from precious plants, the glabridin concentration is 99%. -Whitening the skin from the source, reducing the production and activity of arginase, promoting the absorption, decomposition and excretion of melanin, whitening the skin, reducing the pigmentation of the skin and making the skin translucent.

Glabridin is a flavonoid extracted from the precious plant Glycyrrhiza glabra. Glabridin is known as "whitening gold" because of its powerful whitening effect, which can eliminate free radicals and melanin in muscle bottom, and it is a holy thing for skin whitening and anti-aging.

Glabridin efficacy

Inhibit tyrosinase?

Human tyrosinase is an essential enzyme, which can regularly produce melanin and turn skin or eyes from brown to black. We know that skin exposure to ultraviolet rays can cause some reactions (such as inflammation). Because the phospholipid membrane of skin tissue was destroyed by reactive oxygen species induced by ultraviolet rays, this histological change showed erythema and pigmentation. Reactive oxygen species (ROS) is a substance that can cause skin pigmentation, so inhibiting its production can inhibit the production of melanin. Glabridin is the most expensive and effective whitening ingredient among all whitening ingredients.

anti-inflammatory action

The experiment confirmed the anti-inflammatory activity of glabridin. Pigmentation was induced by ultraviolet irradiation in guinea pigs, and then 0.5% glabridin solution was applied. It was found that glabridin reduced skin inflammation caused by ultraviolet stimulation. Use a value to represent erythema on the skin. By recording the A value (colorimeter reading) of glabridin before and after irradiation, the degree of inflammation reduction can be calculated. The researchers studied the inhibitory effect of glabridin on cyclooxygenase activity. 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 indacin), glabridin can inhibit cyclooxygenase. It is believed that glabridin can affect the production of arachidonic acid by inhibiting cyclooxygenase, thus reducing inflammation.

Antioxidant effect?

Glabridin has a strong scavenging effect on free radicals. Vitamin C, vitamin E and β -carotene are recognized as the three kings of anti-oxidation and anti-aging. Glabridin has the same anti-aging ability as vitamin E, and it is a natural antioxidant. It is reported that its antioxidant effect is obviously better than BHA and BHT.
