MELA B3 double dose intensive serum

La Roche-Posay Mela B3 Double Dose Serum: a potent day-and-night depigmenting treatment featuring Melasyl and Niacinamide. This formula marks the brand’s first integration of Melasyl™’s targeted depigmentation with Proxylane™’s firming action, delivering a two-pronged approach that tackles stubborn dark spots while restoring facial density and volume. In clinical tests, the serum reduced the intensity of tenacious spots by about 30% and immediately increased firmness by around 20% after a single use. Its light, fluid texture absorbs quickly and leaves no greasy residue, making it easy to add to both morning and evening routines.Main benefits
