La Roche-Posay’s Mela B3 Double Dose is designed to support mature skin, visibly improving the look of tone and texture while you sleep. At the heart of the formula, Melasyl™ targets the appearance of dark spots, while Proxylane™ helps to maintain moisture levels for a smoother, more balanced finish. Together, this dual-action blend helps to refine texture, enhance firmness, and address visible discolouration. With a lightweight, melt-in emulsion, it absorbs quickly into the skin, delivering lasting comfort. Niacinamide and glycerin further support a brighter, more even-looking complexion.
