KOJIC ACID: A SKIN LIGHTENING AGENT

This article deals with the study of kojic acid (KA), a tyrosinase inhibitor that has been extensively studied for its ability to lighten skin and treat hyperpigmentation, including melasma. KA, which is derived from fungi, reduces dark patches and UV-induced pigmentation by blocking the synthesis of melanin. To improve efficacy and stability, however, problems including cytotoxicity, instability, and skin irritation have led to a great deal of research on KA derivatives and combination therapy, especially with substances like hydroquinone and glycolic acid. The Cosmeceutical component Review (CIR) states that because of its cytotoxicity, this component (KA) can be used safely at concentrations up to 1%. Its safety at concentrations of 2% or less is further supported by other scientific studies. This study emphasizes the promise of KA for the long-term, efficient treatment of pigmentation problems in dermatology and cosmetics by highlighting its uses, safety profile, and developments in KA-based therapies.
