Kojic Acid is a natural compound derived from fungi, particularly from the fermentation of rice. It is commonly used in skincare products for its ability to lighten skin and reduce the appearance of dark spots, hyperpigmentation, and uneven skin tone. This acid works by inhibiting the production of melanin, the pigment responsible for skin color. As a result, it can help achieve a brighter complexion. Kojic Acid is often found in creams, serums, and soaps, making it a popular choice for those seeking to improve their skin's appearance.
