Kojic Acid is fermented and purified by glucose or sucrose under the action of koji. Its whitening mechanism is to inhibit both tyrosinase activity and N-DHICA oxidaSe activity. Also it can block dihydroxyindole polymerization. Kojic Acid is a rare single whitening agent that inhibits multiple enzymes simultaneously.
We also have available Kojic Acid Dipalmitate
Inhibits melanin formation
Great alternative to Hydroquinone
Lightens visible sun damage, age spots, or scars
