Improve skin tone and enhance skin clarity with La Roche-Posay Mela-D Pigment Control - Concentrated Serum. Powered by glycolic acid and LHA, this nighttime serum exfoliates skin to visibly reduce the appearance of dark spots and discoloration for a more even tone. This La Roche-Posay dark spot serum also contains kojic acid, which helps prevent melanin production, the pigment responsible for color in the skin. While many skin brighteners can cause skin sensitivity and irritation, La Roche-Posay Mela-D Pigment Control is gentler on skin because it contains thermal dermobiotic, a unique ingredient that helps soothe the complexion. For best results, apply this dark spot serum at night and follow with SPF 30 sunscreen in the morning.
