La Roche-Posay Mela B3 Serum is an advanced anti-hyperpigmentation treatment designed to visibly reduce dark spots, including persistent ones. Formulated with 10 percent Niacinamide (Vitamin B3) and the patented Melasyl ingredient, it targets melanin production to correct existing pigmentation and prevent future discoloration. The lightweight, non-sticky gel-serum texture absorbs quickly, leaving the skin feeling hydrated and soothed. Suitable for all skin tones and types, including sensitive skin, this serum helps achieve a more even and radiant complexion.
