La Roche-Posay Mela B3 Serum is a targeted treatment designed to address uneven skin tone and dark spots. Formulated with niacinamide (Vitamin B3) and the brand's signature Thermal Spring Water, this lightweight serum works to visibly reduce the appearance of hyperpigmentation and melasma over time. The serum absorbs quickly without leaving a greasy residue, making it suitable for daily use morning and night. Its gentle yet effective formula helps restore a more radiant, even complexion while strengthening the skin barrier. Ideal for those struggling with post-inflammatory hyperpigmentation, sun damage, or melasma concerns. Dermatologist-tested and suitable for sensitive skin types. For best results, apply to clean skin before moisturizer and always use SPF during the day.
