Our first retinol serum to fight the visible signs of ageing with a unique formulation for sensitive skin. It's clinically proven to firm, fill and smooth. Specifically formulated for those concerned with dehydration, skin irregularities and wrinkles, but also searching for a serum suitable for sensitive skin. Retinol targets fine lines and wrinkles, improving the appearance of uneven skin texture and tone. Vitamin B3 is a soothing agent that helps keep skin soft, plump and supple by improving moisture retention. Glycerin provides intense hydration, helping to restore the skin's precious moisture barrier. The result is firmer, smoother and more youthful-looking skin. La Roche-Posay's commitment to sustainability is evident in their use of pure and protected thermal spring water, which is over 1700 years old and protected from pollution.
