Kojic Acid A naturally occurring ingredient that is derived from several types of fungi or a byproduct from fermenting sake, soy sauce, rice wine or miso. Kojic Acid has a long history of consumption as well as use in Japanese culture, and is considered one of the primary secrets, as well as the cornerstone of Japanese skincare tradition. The main mechanism of action of Kojic Acid is prevention of the formation of tyrosine in the skin, an amino acid that produces melanin, which in turn causes dark spots, freckles and other skin damage. When the production of melanin is inhibited, it results in your skin looking younger, brighter and lighter. According to a study published by the Journal of Pharmacy and Pharmacology, Kojic Acid has an "excellent whitening effect" on the skin. [1] An additional study on the efficacy of Kojic Acid published in the Journal of Dermatologic Surgery suggested that Kojic Acid is "highly effective in reducing the pigment in melasma patients" and should be a primary tool used by dermatologists for skin discoloration.[2]
