Cojic Acid is a natural compound derived from fungi, particularly from the fermentation of kojic rice. It is commonly used in skincare products for its skin-lightening properties, helping to reduce the appearance of dark spots and hyperpigmentation. Cojic acid works by inhibiting the enzyme tyrosinase, which is essential for melanin production in the skin. In addition to its skin-lightening effects, Cojic Acid also has antioxidant properties, which can help protect the skin from damage caused by free radicals. It is often found in creams, serums, and soaps, making it a popular choice for those seeking a brighter, more even skin tone.
