Bioderma Pigmentbio Brightening Night Renewer is a night facial cream inspired by leading treatments used by dermatologists (like Kligman's Trio), Laboratoire Bioderma designed LumiReveal Technology to provide an option for people with hyperpigmented skin without the associated cutaneous side effects. This technology works effectively and durably on the 3 biological stages that cause hyperpigmentation, while ensuring good tolerance: > Inflammation: glabridin reduces inflammation, which causes an overproduction of melanin; > Production: andrographolide + lysine azelate limit melanin production; > Elimination: Epidermactiv boosts cellular renewal by eliminating cells filled with melanin. LumiReveal Technology is supplemented by a cocktail of vitamins that are essential for the skin: vitamin C, E and PP which protect and strengthen the skin barrier. Pigmentbio Night Renewer also contains an active ingredient that is fully dedicated to anti-ageing action: hexapeptide-2. It helps regulate collagen production for smoother and firmer skin in the morning.
