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 lines, wrinkles and sun damage. The formula is specially designed to be effective while remaining suitable for sensitive skin. The serum should be applied in the evening, using 3-4 drops on cleansed face and neck before moisturizer. Sunscreen application is essential the following day. The product comes in a 30ml bottle with a dropper applicator. Note that pure retinol may turn yellow when exposed to air, but this does not affect its efficacy or tolerance.
