Kojic Acid

What is it

What is Kojic Acid?

Kojic acid is a naturally occurring compound produced through the fermentation of certain fungi. In dermatology, it is one of the most well-studied tyrosinase inhibitors. By blocking tyrosinase, kojic acid helps fade existing dark spots, hyperpigmentation, and uneven tone over time, while also functioning as an antioxidant.
