La Roche-Posay's Mela B3 range combines the multi-patented Melasyl™ ingredient - our active melanin trapper - with Niacinamide for multi-action against hyperpigmentation. Melasyl™ intercepts excess melanin at a different stage of its production before it marks the skin. Correct the appearance of hyperpigmentation and dark spots, even persistent ones, whilst helping prevent the appearance of future dark spot discolouration.
