At the heart of the Guerlain Super Aqua-Serum, a bestseller for the last 25 years, lies Aquacomplex, which purifies cellular water to improve its circulation, restoring a youthful appearance and providing skin with powerful age-defying hydration. The first BB Cream infused with Super Aqua-Serum, this true Beauty Balm delivers, in a single step, instant and long-lasting hydration (12 hours)**, smoothes out wrinkles and fine lines, and evens out the complexion. This subtly tinted, feather-light texture protects the skin from both UV rays and dehydration while perfecting the complexion for a naturally radiant glow. Comes in two shades: "Light" for pale to medium complexions and "medium" for medium to dark complexions.
