La Roche Posay Retinol B3 Serum 30Ml

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 wrinkles and sun damage. This lightweight formula is specially designed for sensitive skin, leaving it smoother, hydrated and renewed. 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 contains La Roche-Posay thermal spring water and has a gradual-release technology for optimal effectiveness and skin tolerance.
