Detailed Introduction of Sponge Glabridin
Glabridin is unique isoflavan flavonoid extracted from Glycyrrhiza glabra root, well-known as “Brightening Gold”, the core plant raw material for high-end spot fading, soothing and anti-aging skincare worldwide. We adopt authentic Xinjiang licorice as raw material, low-temperature alcohol extraction and multi-stage resin purification technology, launching three grades: 40% cost-effective extract, 90% medium balanced powder and 95% high-purity crystal, covering mass-market brightening masks, mid-range repair serums, medical beauty spot ointment and lab reference standards. The whole production is controlled under low light & low temperature to prevent glabridin oxidation and deactivation. Every batch is quantified by HPLC. Pesticide residues, heavy metals and solvent residues are far below EU & US cosmetic limits. 40% glabridin features high cost performance for entry-level brightening masks and herbal drinks; 90% balances purity & cost, the mainstream raw material for brightening & anti-redness serums; 95% crystal has minimal impurities without interfering flavonoids, specially for premium medical beauty products and pharmaceutical pharmacological calibration. Glabridin delivers synergistic multi-effects: powerfully inhibit tyrosinase to block melanin formation, relieve inflammatory redness, scavenge free radicals & resist photoaging. It works perfectly with asiaticoside, panthenol and niacinamide for synergistic effects. Liposoluble glabridin fits ointments, serums and oil formulas; cyclodextrin encapsulation can improve water solubility for aqueous systems. Complete chromatograms and full export certificates are provided per batch, supporting one-stop service for global cosmetic manufacturers, plant extract traders and skincare R&D labs.
