ActiBiso™ Arbutin Pro is a powerful whitening agent. Its molecular structure resembles that of tyrosine, allowing it to competitively inhibit tyrosinase. By binding directly to tyrosinase, it competes with dopa for the enzyme's active site, thereby reducing the activity of tyrosine in the skin, hindering melanin production, and promoting the breakdown and removal of melanin. This process effectively minimizes melanin accumulation, helping to eliminate spots and freckles. Moreover, it is non-toxic, non-irritating, and non-sensitizing to melanocytes, while also displaying antibacterial properties.
