Pigmentation Control Serum is formulated with 3% Tranexamic and 2% Glycolic acid. Together they reduce tyrosinase activity of melanocytes thus preventing UV-induced pigmentation, melasma, hyperpigmentation, post inflammatory hyperpigmentation(PIH), PIE(Erythema) and acne scars. It suppresses melanin production and inhibits melanosome transfer hence reduces hyperpigmentation and melasma.
