Active whitening ingredient kojic acid

It targets melanin production at an early
and effectively stops melanin production.

Kojic acid's whitening action works in melanocytes, inhibiting the activity of tyrosinase, the enzyme that turns on melanin production. It effectively inhibits melanin production by using a process called chilation to steal the copper ions that are active inside tyrosinase, preventing it from functioning. Kojic acid was discovered over 100 years ago. It is produced naturally during fermentation by the koji bacteria used in the production of Japanese sake, soy sauce, and miso.
Research began after it was observed that those who work brewing sake had beautiful, white hands. In 1988 it was officially recognised as an active whitening ingredient (main whitening agent) by the Ministry of Health and Welfare at the time.
