Clinical Summary
A fungal fermentation metabolite that chelates copper in tyrosinase. Use cautiously and avoid high concentrations.
Pharmacological Mechanism & Teratogenic Context
Kojic acid inhibits tyrosinase activity by chelating the essential copper atom. In high animal doses, kojic acid has shown potential thyroid and liver metabolism alterations. EU SCCS guidelines set safe limits at 1%. Obstetricians generally prefer safer brighteners like vitamin C and azelaic acid.
