Kojic acid blocks tyrosinase, an enzyme that produces melanin, making it effective at reducing dark spots and hyperpigmentation. It also has antimicrobial, antiviral, and antioxidant properties. The research shows it's stable enough for use in creams, lotions, soaps, and other skincare products.

This was a literature review that analyzed existing research on kojic acid's properties and applications across cosmetic and pharmaceutical uses rather than a new clinical trial.
