Serum PIGM 400 by Biologique Recherche is a targeted anti-pigmentation serum formulated to prevent new dark spots from forming, reduce the appearance of existing hyperpigmentation and leave the complexion more even, unified and luminous. A complex of Watercress Sprout Extract and Soy-based Pure Genistein provides the formula's core brightening action, while a Chromanyl Palmitate-based Synthetic Peptide — a stabilised Vitamin E derivative — adds a further layer of antioxidant protection. Plum Pulp Extract rounds out the active brightening complex, working at the skin's surface to visibly fade existing discolouration through natural acids and brightening compounds. The watercress targets oxidative stress triggers at their source by neutralising both reactive oxygen species (ROS) and reactive nitrogen species (RNS), while Pure Genistein acts directly on the melanogenesis pathway to inhibit pigment synthesis at the cellular level. The Chromanyl Peptide intercepts free radical chains before they can stimulate melanocyte activity, helping to prevent the environmental triggers that cause dark spots to recur.
