Clinically Proven
Plant Extract (Glycyrrhiza glabra)
Licorice root extract is a powerful yet gentle skin-brightening agent that contains active compounds like glabridin and liquiritin. Unlike harsh brightening ingredients, it inhibits tyrosinase (the enzyme that produces melanin) without causing irritation, making it ideal for sensitive skin. It also has remarkable anti-inflammatory properties that calm redness and irritation. The extract helps fade hyperpigmentation, dark spots, and post-inflammatory marks while simultaneously soothing the skin—making it one of the most versatile brightening ingredients available.

Clinical studies confirm licorice root's brightening and anti-inflammatory effects. Research shows glabridin (the main active) inhibits tyrosinase more effectively than many synthetic alternatives. Studies in Journal of Cosmetic Dermatology demonstrate significant improvement in hyperpigmentation with minimal irritation. Its anti-inflammatory properties are well-documented, making it particularly effective for redness-prone skin types.
Licorice root extract is typically used at 1-5% in formulations. It's water-soluble and works well in serums, toners, and moisturizers. The two main active compounds—glabridin (for brightening) and liquiritin (for even skin tone)—are both effective. For maximum benefit, look for products that specify "glabridin-rich" or "standardized licorice extract." It pairs beautifully with other brightening agents like vitamin C, niacinamide, and alpha arbutin.
Did You Know?
Licorice root has been used in traditional Chinese medicine for over 3,000 years! It's one of the oldest known herbal remedies and was even mentioned in ancient Egyptian papyrus texts.
Licorice root comes from the Glycyrrhiza glabra plant, native to Mediterranean regions, Central Asia, and parts of China. The root is harvested, dried, and extracted to create the skincare ingredient. Sustainable farming practices ensure the plant can be harvested without depleting natural populations. Look for extracts from responsibly sourced licorice root, preferably from organic farms.
