Glabridin

Product Description

Glabridin is a high-purity isoflavan, celebrated throughout the cosmetic industry as "Whitening Gold" for its exceptional skin brightening capabilities. Extracted from the root of the licorice plant, it is one of the most potent natural tyrosinase inhibitors available. Its key advantage is its powerful, multi-pathway approach to achieving a luminous complexion: it effectively inhibits melanin production, provides strong antioxidant protection against environmental stressors, and soothes the skin with its potent anti-inflammatory properties. For formulators developing premium, high-performance whitening and spot-correcting products, Glabridin is the ultimate science-backed botanical active.

Product Uses

This powerful botanical active is a cornerstone for a wide range of high-end brightening and soothing skincare:

• Brightening Products: The ideal hero ingredient for dark spot correctors, whitening serums, and even-tone facial creams.
• Soothing Formulations: A key component in products for sensitive or blemish-prone skin to calm redness and prevent post-inflammatory hyperpigmentation (PIH).
• Anti-Aging: Incorporated into anti-aging lines for its potent antioxidant and collagen-protecting benefits.

Formulation Suggestions

The recommended dosage is between 0.05-0.2% (based on pure Glabridin). As a powder with poor water solubility, it must be pre-dissolved in a suitable solvent system, such as a blend of butylene glycol, pentylene glycol, or ethanol, before being added to a formulation. It is best incorporated during the cool-down phase. Due to its sensitivity to light, opaque or UV-protective packaging is essential. It works synergistically with other brightening agents like Niacinamide and Vitamin C derivatives.
