It is an important active ingredient in licorice, has excellent antioxidant and whitening effects, and is widely used in skin care products and medicine.

 

It has high stability, good fat solubility, and is easy to penetrate the skin barrier, so it is easier to be absorbed by the skin when added to cosmetics.

1. Whitening and lightening of spots

• It can inhibit the activity of tyrosinase and reduce the production of melanin. Its whitening effect is better than vitamin C and arbutin.
• Clinical studies have shown that after continuous use of skin care products containing 0.5% glabridin powder for 8 weeks, the area of ​​pigmentation is reduced by more than 30%.

 

2. Antioxidant
It has a good ability to scavenge free radicals, protect collagen, and delay skin photoaging.

 

3. Anti-inflammatory and soothing
It can reduce the skin inflammation caused by ultraviolet rays, relieve redness and sensitivity.

 

4. Medical application
Glabridin powder has potential anti-tumor and lipid-lowering effects, but more research data is needed to prove it.

 

 

1. Irritation
If a high concentration of >2% is used, it may cause redness or tingling in sensitive skin, but the skin needs to be tolerated first to avoid allergies.

 

2. High cost
The natural extraction process is complicated, and the price of 1kg of glabridin raw material can reach tens of thousands of yuan, resulting in a high price for products containing this ingredient.

 

3. Photosensitivity
Glabridin powder is not phototoxic in itself, but it needs to be used with sunscreen to maintain the effect.

 

4. Use with caution in pregnant women
In the absence of sufficient safety research, it is recommended to avoid high doses during pregnancy.

 

 

Product	Benefits	Features
Glabridin	Inhibit tyrosinase activity, antioxidant	Multi-channel whitening, gentle and non-irritating, suitable for sensitive skin
Vitamin C	Lightens melanin, inhibits tyrosinase, antioxidant	Requires high concentration (10%~20%), but is easily oxidized and needs to be well preserved
Nicotinamide	Block melanin transport and resist glycation	Strong tolerance, but the spot-lightening effect is slow when used alone
Arbutin	Inhibits tyrosinase	Including Alpha/Beta, Alpha arbutin is more stable
Kojic acid	Chelated copper ions inhibit tyrosinase	Highly effective but may be irritating, restricted in some countries
Tranexamic acid	Inhibit prostaglandin synthesis and reduce inflammatory pigmentation	Oral administration is more effective, while topical administration requires long-term use

 

Key differences:

 

• Glabridin powder has both antioxidant and anti-inflammatory properties and is suitable for sensitive skin; kojic acid and high concentrations of VC may be highly irritating.
• Niacinamide and tranexamic acid focus on preventing pigmentation, while glycyrrhizin and arbutin directly block melanin production.
