What are the benefits?
The Licorice Root Extract Powder retains a variety of natural components from licorice, offering comprehensive benefits, including anti-inflammatory, soothing, and antioxidant effects. Its flavonoids and polyphenols possess antioxidant properties, helping to combat free radicals; various complex components also support daily digestive health.
Glabridin inhibits tyrosinase activity, effectively blocking melanin production and is a core ingredient in whitening skincare products; its glycyrrhizic acid can suppress inflammatory responses and relieve skin redness and itching.
Glycyrrhetinic acid has broad pharmacological activities, including anti-inflammatory, antiviral, hepatoprotective, antioxidant, and immunomodulatory effects.
The active ingredient glycyrrhizic acid has been widely used in traditional medicine for anti-inflammatory and hepatoprotective treatments and has recently gained significant attention in the field of dermatology.

Glabridin: Experimentally Supported Multi-Target Skin Brightening Mechanism
Traditional research suggests that glabridin primarily exerts its skin-brightening effect by inhibiting tyrosinase activity and reducing melanin production. Recent research has found that glabridin can also accelerate melanosome degradation by promoting autophagy in keratinocytes.
In cell models, artificial epidermal models, and live zebrafish models, glabridin demonstrated a melanosome-promoting effect. The study found that glabridin can activate autophagy-related signaling pathways, helping to reduce melanosome accumulation in keratinocytes, thereby improving dull skin tone.
Furthermore, it was found that excessive melanin accumulation may affect mitochondrial function in keratinocytes and increase oxidative stress, while glabridin, by promoting melanin clearance, helps maintain cellular energy metabolism balance and antioxidant status.
Therefore, glabridin is considered to have multi-dimensional skin-brightening potential, specifically in the following aspects:
- Inhibiting tyrosinase activity
- Reducing melanin transport and lowering pigmentation
- Activating autophagy and promoting melanosome degradation
- Providing antioxidant support
This study further enhances the application value of glabridin as a natural plant-derived skin-brightening ingredient in high-end skincare products.
