What does Kojic Acid do, and how does it work with the other ingredients?

Kojic Acid is a naturally derived brightening agent produced during the fermentation of certain fungi, and it has a long track record in skincare for reducing the appearance of dark spots, uneven tone, and hyperpigmentation. It works by inhibiting an enzyme called tyrosinase, which plays a key role in melanin production — the process that creates dark spots. At 3%, Kojic Acid in this formula complements the Tranexamic Acid (which disrupts the signaling that triggers melanin overproduction) and the Azelaic Acid (which normalizes skin cell turnover and reduces pigment transfer) to address discoloration through multiple mechanisms simultaneously. The result is a broader, more comprehensive brightening effect than any single ingredient can deliver alone.
