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.
Key properties & actions
Kojic acid is known to be a naturally occurring compound produced when koji mold ferments rice or soybeans. It is believed to work by binding to tyrosinase — the key enzyme in melanin synthesis — and reducing its activity, which may help slow the progression of pigmentation darkening.
How to manage
When uneven tone, melasma, or dark spots are a concern, adding a kojic acid serum or ampoule to your evening routine may be beneficial. Since it is susceptible to air and light and prone to discoloration, products in airtight, opaque packaging are recommended. Sunscreen should always be used during the day alongside this ingredient. If irritation occurs, reducing frequency of use is advisable, and if pigmentation persists, consulting a dermatologist is recommended.
Good to know alongside
Kojic acid is frequently mentioned alongside brightening ingredients such as vitamin C, arbutin, and niacinamide, and is known to belong to the group 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 should be avoided.
