The MelaB3 Serum: Intense Anti-Dark Spot Serum for Hyperpigmentation (30ml) from La Roche-Posay works to deliver tone-correcting results over time. Powered by 10% niacinamide and Melasyl (one of the brand's proprietary ingredients), this potent yet gentle must-have helps to minimise the appearance of dark spots and post-acne marks to reveal brighter and more radiant skin. Thought it couldn't get any better? It's also infused with the brand's very own 'Thermal Spring Water' to hydrate your complexion and leave it with a fresh, soothing feel that lasts.
