It is considered one of the most powerful whitening ingredients in cosmetics currently available. Its core advantage lies in its extremely strong tyrosinase inhibitory ability. Studies have shown that the inhibition rate of this peptide on human tyrosinase is 119 times that of 377, 454 times that of kojic acid, and 3636 times that of arbutin. Clinically, treatment with a concentration as low as 0.1% can reduce the appearance of age spots.
