Co-developed with dermatologists, the La Roche-Posay MelaB3 Serum is a lightweight formula designed to improve the appearance of uneven skin tone and discolouration. Suitable for all skin types and tones, including sensitive skin, the formula helps promote a more even-looking and radiant complexion. Powered by multi-patented Melasyl™ and 10% niacinamide (vitamin B3), the serum helps to reduce the look of dark spots while locking in long-lasting hydration. The lightweight texture absorbs easily, leaving skin feeling hydrated, smoother and more balanced, with a brighter, more uniform appearance over time.
