La Roche-Posay Pure Niacinamide 10 Serum is a dermatological anti-aging serum that targets dark spots, discolorations, and uneven skin tone. It contains 10% pure niacinamide, a powerful ingredient that helps fade hyperpigmentation, rebalance skin tone, and improve skin barrier function. It also contains hyaluronic acid, a hydrating molecule that plumps and smooths the skin. This serum is suitable for all skin types, including sensitive skin, and is allergy-tested, non-comedogenic, oil-free, and paraben-free. It delivers visible results starting from the first week of use, reducing the size and color of dark spots, post-acne marks, and stubborn pigmentation. With continued use, it reveals a brighter, more radiant, and more even complexion.
