Bioderma White Objective Lightening Serum is a hyper-pigmentation treatment suitable for all skin, including sensitive skin and pregnant women. This serum acts on all stages of melanin production thanks to the WO Patent which is based on andrographolide, glabridin, melanostatin, and lysine aze-late to inhibit melanin production and help prevent indirect melanin synthesis. Vitamin C and glycolic acid help with already existing hyperpigmentation to remove spots due to their ability to boost cellular renovation and whitening properties.
