The La Roche-Posay Retinol B3 Serum is a 30ml anti-aging treatment formulated to address wrinkles and dull skin. This serum features a combination of pure retinol, niacinamide (vitamin B3), and La Roche-Posay thermal water. The retinol works to improve skin texture, reduce the appearance of fine lines, and support collagen production. Niacinamide helps balance skin tone and supports the skin barrier, while the thermal water provides a soothing effect. This lightweight, non-comedogenic formula is free from fragrance, parabens, and mineral oils, making it suitable for normal to oily skin types. To use, apply a small amount to clean, dry skin in the evening, avoiding the eye and lip areas. Start with two to three applications per week, gradually increasing frequency as tolerated. Always use sunscreen during the day while using this product.
