PROPERTIES Serum suitable as an intensive shock treatment to counteract localized hyperchromia (sun spots, chloasma, acne lesions, anti-inflammatory or medication-induced hyperchromia, uneven tone). Formulated with anti-stain active ingredients (Butyl Resorcinol, High Tech Vitamin C and PP, Tetrapeptide-30) and enriched with fruit-derived AHAs, it promotes the elimination of pigment-laden cells. HOW TO USE Apply morning and night. For a more localized effect, apply 1-2 drops directly to the area to be treated.
