What is Kojic Acid?

A natural melanin inhibitor produced during the koji fermentation process

Inhibits the tyrosinase enzyme to block melanin synthesis. Effective for melasma and dark spots.

Main causes & characteristics of Kojic Acid

Kojic acid is known to be a naturally occurring compound produced when koji mold ferments rice or soybeans. It is known to help slow the deepening of pigmentation by binding to tyrosinase — the key enzyme in melanin synthesis — and reducing its activity.

Managing Kojic Acid

When uneven skin tone, dark spots, or melasma are a concern, it is recommended to incorporate kojic acid in serum or ampoule form into an evening skincare routine. Because it is susceptible to oxidation and light exposure, products in airtight, opaque packaging are advised. Sunscreen should always be applied during the day. If irritation is felt, reducing frequency of use is recommended, and if pigmentation persists, consulting a dermatologist is recommended.

Related information

Kojic acid is frequently mentioned alongside other brightening ingredients such as vitamin C, arbutin, and niacinamide, and is known to belong to the class of whitening actives that target the tyrosinase pathway.

Everyday care tips

After opening, it is best to use the product as soon as possible, and products that have turned brown in color should be avoided.
