Descrizione

Applicazioni

Azioni biochim/fisiol

Kojic acid is derived from some fungal species such as, Aspergillus, Acetobacter and Penicillium.. It halts melanin synthesis by inhibiting tyrosinase enzyme. It is used in the preparation of skin whitening cosmetics. However, kojic acid usage is minimal in cosmetics, as it induces skin irritation by its unstability and cytotoxic nature during long storage. It is an antioxidant and elicits radioprotective effects on chelating with manganese and zinc.

Tyrosinase inhibitor.
