🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by inhibiting the enzyme tyrosinase, which is essential for converting the amino acid tyrosine into melanin. By blocking this step, it reduces the formation of new melanin pigment in the skin. It also appears to damage melanocytes, the pigment-producing cells, and interfere with the structure of melanin granules. The result is a gradual lightening of hyperpigmented areas over several weeks of regular use.
