  • Détails du produit
Kojic acid (CAS 501-30-4), also known as aspergillic acid and aspergillic acid, is a specific inhibitor of melanin. After entering skin cells, kojic acid can coordinate with copper ions in cells, change the three-dimensional structure of tyrosinase, prevent the activation of tyrosinase, and thus inhibit the formation of melanin. Kojic acid whitening activators have better tyrosinase inhibition effect than other whitening activators. It does not act on other biological enzymes in the cell, and has no toxic effect on the cell. At the same time, it can enter the intercellular matrix to form the intercellular glia, which plays a role in water conservation and increasing skin elasticity. At present, it has been blended into various cosmetics to make whitening cosmetics for freckles, senile spots, pigmentation and acne.

Kojic acid is also widely used in medicine and food because of its role in scavenging free radicals, enhancing cell vitality, preserving food freshness and color, etc.
