Whether you have been struggling with an uneven skin tone, dark spots that are hard to get rid of, or dull skin, kojic acid serum could be the new best friend of your skin. In this guide, we will explore all the reasons why kojic acid serum is an essential addition to your skincare routine, the right way to apply it, kojic acid serum myths, and the best recommendations, and frequently asked questions.

What is Kojic Acid?
Kojic acid is a natural product that is extracted in fungi, especially Aspergillus oryzae, also referred to as koji mold. It is also a byproduct of fermentation of rice, soy and sake.
How Does Kojic Acid Work on the Skin?
This wonder ingredient works by the inhibition of the formation of the enzyme tyrosinase that produces melanin (pigment). Decreased tyrosinase = less melanin = lighter everyday-fairer skin.
