Detailed answer

Kojic acid is a natural skin lightening agent that inhibits the production of melanin, the pigment responsible for uneven skin tone. It works by suppressing the enzyme tyrosinase, which is involved in melanin synthesis. This helps to fade hyperpigmentation, dark spots, and melasma, resulting in a more even complexion. Kojic acid can be found in various skincare products like serums, creams, and soaps, and is often used in combination with other ingredients like vitamin C or retinol for enhanced results. It is important to note that prolonged or excessive use of kojic acid can cause skin irritation, so it's advisable to start with a low concentration and gradually increase if necessary while closely monitoring the skin's reaction.
