Glabridin Extract, an isoflavonoid derived from the roots of Glycyrrhiza glabra L. (licorice), is globally recognized as the premier natural skin-lightening active ingredient. Its extreme rarity, complex extraction process, and remarkable tyrosinase inhibitory activity have earned it the moniker "whitening gold" within the industry.
At Xi'an Le-Nutra Ingredients Inc., our Glabridin powder is produced using a proprietary multi-stage counter-current extraction and decolorization technology. This innovative approach effectively overcomes the challenges of dark coloration and strong odor often associated with traditional extracts. Our product not only inhibits melanin synthesis at its source but also offers significant anti-inflammatory and antioxidant benefits, making it the core ingredient in high-end whitening serums, anti-aging creams, and soothing formulations.

1. Advanced Skin Brightening and Even Toning:
Glabridin Extract deeply penetrates the basal layer of melanocytes. It not only inhibits the synthesis of new melanin but also synergistically accelerates the metabolism of pre-existing melanin. This results in a significant improvement in dullness, sallowness, and uneven skin tone.
2. Fading Stubborn Pigmentation and Post-Acne Marks:
It demonstrates exceptional efficacy in fading sun spots, post-inflammatory hyperpigmentation (PIH), and melasma. Furthermore, it minimizes the risk of rebound hyperpigmentation upon cessation of use.
3. Antioxidant and Photoprotective Properties:
As a potent antioxidant, Glabridin neutralizes reactive oxygen species (ROS) generated by UV radiation. This protects dermal collagen from degradation, thereby preventing the formation of wrinkles and laxity.
4. Soothing and Calming Sensitive Skin:
For redness caused by environmental stressors, Glabridin cosmetic ingredient rapidly calms nerve endings and downregulates pro-inflammatory cytokine expression. It is a key ingredient in post-procedure skincare formulations.
Natural alternatives to synthetics: As consumers increasingly question the safety of chemical skin-lightening agents like hydroquinone and resorcinol, Glabridin is steadily replacing synthetic ingredients and becoming the preferred choice for premium brands.
The "gentle whitening" concept: Market focus in 2026 will shift away from aggressive acid peels towards "barrier-friendly" skin lightening, particularly in the Asian market.
Ubiquity of microencapsulation technology: To enhance stability, the use of encapsulated Glabridin in aqueous formulations is experiencing explosive growth.

The key lies in the active ingredient. Ordinary licorice extracts mainly contain glycyrrhizic acid or licoflavone, whereas Glabridin is found only in specific varieties of licorice roots and in extremely low concentrations. Extracting 1kg of 40% Glabridin requires consuming several tons of high-quality licorice raw materials.
Yes, it is sensitive to light and heat. We recommend adding a small amount of antioxidants (such as Vitamin E or sodium metabisulfite) to the formulation and using it within a pH range of 5.0-7.0. Additionally, light-blocking packaging is essential.
The 40% specification offers the best cost-effectiveness and is suitable for most mass-market and high-end skincare products, as it also contains other beneficial licorice flavonoids that provide synergistic effects. Specifications above 90% are more suited for premium anti-aging serums or pure white creams with extremely high color requirements.
Each batch of raw materials undergoes rigorous inspection, process control, and quality testing to ensure that purity, physical and chemical indicators, and microbial standards comply with international cosmetic and food ingredient requirements. Concurrently, we provide a complete Certificate of Analysis (COA).
Yes. We support OEM/ODM formula development and can provide raw materials in different concentrations, particle sizes, solubilities, or carrier forms according to customer requirements, to meet specific product design needs.
Yes. We can provide small batch samples for R&D testing and assist customers with formula validation and application testing to help expedite the product development cycle.
