product description
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.

Product Characteristics
• Highly Effective Tyrosinase Inhibitor: Studies have shown that glycyrrhizin's whitening effect is 232 times that of Vitamin C and 16 times that of hydroquinone, with no cytotoxicity or irritation.
• Color Control: Le-Nutra's proprietary decolorization process ensures the whiteness of the high-purity powder, preventing yellowing in the final product and enhancing the premium feel of the skincare.
• Multiple Activities: In addition to its powerful whitening effect, it is also an excellent free radical scavenger, effectively alleviating UV-induced erythema and inflammation, possessing dual "whitening + repairing" properties.
• Clean Label & Safety: 100% naturally derived, non-GMO, and free of any prohibited chemical additives, aligning with the Clean Beauty trend.
• Application Compatibility: Addressing the challenge of difficult dissolution, we developed microencapsulated, water-soluble glycyrrhizin, allowing it to exhibit excellent compatibility in lotions, toners, and serums.
Product Efficacy
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.
Market Application
• Brightening Serums: As a core active ingredient, a typical usage recommendation ranges from 0.05% to 0.1% (based on a 40% concentration).
• Whitening Creams: Leveraging its excellent oil solubility, it integrates seamlessly into oil-based formulations.
• Anti-aging Formulas: Utilizes its free radical scavenging properties.
• Post-Sun Repair and Sunscreen Support: Mitigates UV-induced erythema and thermal damage to the skin.
• Aqueous Formulations: In conjunction with nanoliposome technology, it can be directly incorporated into toners and water-based masks.
Market Trends 2026
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.
FAQ
Q1: Why is the price of Glabridin powder significantly higher than other licorice extracts?
A: 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.
Q2: Does it easily discolor in formulations? How can this be managed?
A: 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.
Q3: Which is better, the 40% or 90% specification?
A: 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.
Q4: Are your products tested for pesticide residues?
A: Absolutely. Our Glabridin meets the strictest standards, ensuring worry-free export.
Q5. How is the quality of raw materials guaranteed at the factory?
A: 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).
Q6. Do you support OEM / customized formula production?
A: 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.
Q7. Does the factory support small batch samples or technical development?
A: 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.
