KOJIC ACID

Depending on the source of the carbon, kojic acid can be produced chemically using pyranoid 3,2-enolones or biologically by Aspergillus oryzae and Aspergillus flavus when they directly ferment glucose.

Kojic acid is used as a skin-lightening agent in cosmetic products. Kojic acid inhibits melanosis by interfering with the uptake of oxygen required for enzymatic browning.

Kojic acid inhibits the growth of bacteria, fungi, and the multiplication of viruses. Tyrosinase, a key enzyme in the biosynthesis of the skin pigment melanin, is inhibited in its rate-limiting catecholase activity. It is used in the cosmetics industry because of its ability to fight bacteria, fight free radicals, and protect colors.

It works as an antioxidant and a skin-lightening agent. It is used in cosmetic formulations for fading dark spots, to even the skin tone, and in anti-ageing products.

It’s been approved for use in cosmetic products in concentrations of 1 per cent or less.
