Kojic acid is a safe and effective skin lightening agent, says Dr. [Doctor’s Name], a dermatologist at [Hospital Name]. It is well-tolerated by most people and can be used on all skin types.
Kojic acid works by inhibiting the production of melanin, the pigment that gives skin its color. Melanin is produced by cells called melanocytes. When kojic acid is applied to the skin, it binds to tyrosinase, an enzyme that is necessary for the production of melanin. This binding prevents tyrosinase from functioning, which in turn reduces the production of melanin.
Kojic acid is available in a variety of products, including creams, serums, and soaps. It is important to use kojic acid products as directed and to avoid using them on broken or irritated skin.
