At the heart of <b>Guerlain</b>&#39;s Super Aqua-Serum, a bestseller for the last 25 years, lies Aquacomplex, which &nbsp;purifies cellular water* to improve its circulation, restore a youthful appearance and provide skin with powerful age-defying hydration. The first <b>BB Cream</b> 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.
