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 effectively reduce the appearance of lines, wrinkles, and sun damage. This dermatologically-tested formula is suitable for sensitive skin while providing optimal skin renewal and hydration. 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 after use. The pure retinol in the formula may turn yellow when exposed to air, but this does not affect its efficacy or tolerance. The lightweight formula absorbs quickly and is designed for gradual release to ensure both effectiveness and skin tolerance.
