Description
Co-developed with dermatologists, this lightweight gel-serum targets persistent discolouration while remaining suitable for all skin types and tones, including sensitive skin. Melasyl™ helps reduce the appearance of stubborn dark spots, while 10% niacinamide helps visibly even skin tone and brighten the complexion. Enriched with La Roche-Posay Thermal Spring Water, sodium hyaluronate, LHA and carnosine, the formula hydrates, gently refines the skin surface and helps protect against oxidative stress for a smoother, more radiant finish.
