La Roche-Posay Pure Retinol Face Serum With Vitamin B3

La Roche-Posay Pure Retinol Face Serum combines concentrated pure retinol and vitamin B3 in an anti-aging formula designed for sensitive skin. This serum helps reduce the appearance of wrinkles, fine lines, and sun damage while leaving skin feeling smoother and more hydrated. 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 formula contains pure retinol that releases gradually for optimal effectiveness and tolerance. The lightweight texture is suitable for sensitive skin. Note that pure retinol may turn yellow when exposed to air, but this does not affect its efficacy or tolerance.
