LA Roche-Posay Niacinamide B9 Serum is a dermatologist-developed repairing and soothing serum designed to strengthen the skin barrier, reduce redness, and restore comfort in sensitive and stressed skin. Suitable for all skin types, including sensitive skin, it helps visibly improve skin texture and resilience.
Formulated with Niacinamide (Vitamin B3) to calm irritation and reinforce the barrier, and Vitamin B9 (Folic Acid) to support skin repair and regeneration, this serum works synergistically to improve overall skin health. Enriched with La Roche-Posay Thermal Spring Water, it delivers immediate soothing benefits while enhancing long-term tolerance.
