La Roche‑Posay Retinol B3 Serum is a high‑performance anti‑ageing treatment formulated in a dermatological laboratory. The advanced formula contains both pure retinol and gradual‑release retinol, enabling a continuous corrective effect on the skin’s surface while respecting skin tolerance. This retinol complex targets the most visible signs of ageing — including deep wrinkles, photodamage (sun ageing), uneven skin tone and loss of firmness. At the same time, the infusion of vitamin B3 (niacinamide) strengthens the skin barrier, soothes sensitivity and improves overall tone and texture. Glycerin and other hydrating actives help keep skin comfortable and replenished.
