Guerlain's Super Aqua Serum has been created to give the skin a powerful new source of anti-wrinkle hydration. It reinforces the skin's protective barrier, enhancing the impermeability of the skin and improving its resistance against aggressions. Enriched with pure and essential hydration, the skin becomes more resistant to visible signs of ageing, reducing the appearance of wrinkles and fine lines. Skin is left smooth, revitalised, radiant, fresh and youthful again. To use: Apply mornings and/or evenings to the cleansed face and neck.
