Kojic acid is an ingredient that’s largely been eclipsed by the substance that it’s a byproduct of- sake! However, kojic acid totally deserves its own spotlight. It’s created during the sake fermentation process of rice and also can be found in mushrooms. Hailed as a complexion saver, it blocks the enzyme that is needed for the production of melanin.
Benefits: Skin brightening and dark spot reduction.
Skin Types: Those with a history of easy scarring would best suit kojic acid, although everyone can use it.
