China Cosmestic Grade Alpha-Arbutin Arbutin CAS No: 84380-01-8, Find details about China Arbutin, Alpha-Arbutin from Cosmestic Grade Alpha-Arbutin Arbutin CAS No: 84380-01-8
Alpha-Arbutin, similar to Arbutin, inhibits the production and deposition of melanin. It inhibits the activity of tyrosinase at very low concentrations. It inhibits tyrosinase better than Arbutin, rapidly whitening and brightening the skin. It effectively diminishes spots, protects skin and reduces skin damage caused by UV rays. The dosage is small, the cost is reduced, and the safety and stability are high. Good compatibility, not affected by temperature, light, etc. in the formulation.
