Everything You Want Gathered Under One Roof-From Cosmetic Raw Materials To Nutritious Supplementary
introduction
Licorice Glabridin is a flavonoid active ingredient extracted from licorice roots. It is a whitening cosmetic additive, the main ingredient of which is licorice flavonoids, a natural substance with an outstanding whitening effect. It is the main functional ingredient of high-end whitening cosmetics in the world. The whitening effect of glabridin is 16 times that of hydroquinone, 232 times that of regular vitamin C, and 1164 times that of arbutin, so glabridin is called whitening gold.

feature
High-purity extraction
Glabridin is produced using modern plant separation and purification technology, with a stable purity of more than 90%, and the measured value is 90.12%, which can ensure sufficient ingredient activity and stable performance.
Good solubility
The presence of multiple phenolic hydroxyl groups in the structure makes Glabridin have good dispersion and solubility in both polar and non-polar systems. It can be completely dissolved in common solvents such as ethanol or butanediol and is easy to add to different dosage forms such as lotions, essences, and masks to meet the development needs of various products.
High safety
Glabridin meets international cosmetic raw material quality control standards in terms of heavy metals (≤ 10 ppm), drying loss (≤5%, measured 1.70%), and microorganisms. The product has passed CTFA certification and has been included in the "China Cosmetic Raw Materials Standard Catalog", and its safety has been widely recognized.
function
Whitening
Glabridin can effectively inhibit tyrosinase activity, block the melanin production pathway, and reduce the formation of spots from the root. Compared with common whitening ingredients, its efficacy is 16 times that of hydroquinone, 232 times that of ordinary vitamin C, and 1164 times that of arbutin.
Strong antioxidant capacity
The SOD-like activity in Glabridin can efficiently remove hydroxyl radicals and superoxide anions, and reduce lipid oxidation and protein damage. At a concentration of 0.1%, its hydroxyl radical scavenging rate reaches 78.3%, much higher than vitamin E (58.6%) and coenzyme Q10 (64.1%).
Anti-inflammatory and antibacterial
By inhibiting the expression of inflammatory factors such as COX-2, Licorice Glabridin can effectively reduce skin redness, fever, and irritation, and at the same time show a certain antibacterial effect. After adding 0.05% Glabridin to the in vitro skin cell model, the average reduction in inflammatory indicators reached 42.6%.
