La Roche Posay Retinol B3 Serum 30 Ml

La Roche-Posay Retinol B3 Serum is an anti-aging face and neck serum that combines pure retinol and vitamin B3 to reduce the appearance of lines, wrinkles, and sun damage. This dermatologist-recommended formula is suitable for sensitive skin while providing optimal effectiveness for smoother, renewed skin. The serum should be applied in the evening, using 3-4 drops on cleansed face and neck before moisturizer. For best results, always apply sunscreen the following day. The pure retinol may turn yellow when exposed to air, but this does not affect its efficacy or tolerance. The formula features a lightweight, hydrating texture and includes La Roche-Posay thermal spring water.
