Kojic acid

Kojic acid is receiving increasing attention in the world of aesthetic medicine and skin care due to its properties for treating pigmentation problems. It is used in creams, serums and chemical treatments to provide more uniform and radiant skin.

This compound derived from rice and mushrooms is named after the Japanese word “koji”, in reference to the mushroom cultures used in the fermentation of traditional Japanese foods.

How does kojic acid work?

Kojic acid acts as an inhibitor of melanin, the pigment responsible for skin color. Specifically, it inhibits the enzyme tyrosinase. By interfering with excessive melanin production, it can help reduce the appearance of dark spots, melasma and freckles.

Unlike other more aggressive treatments, the action of kojic acid is gentle and suitable for a wide range of skin types.

Compared to other treatments targeting hyperpigmentation, kojic acid is considered a mild agent, although this does not mean that precautions should not be taken.

Aesthetic medicine applications

Kojic acid is used as a topical product in creams, serums and gels. They are designed to help lighten and even skin tone, which can result in a more radiant and youthful appearance.
