At the heart of Guerlain's Super Aqua-Serum, a bestseller for the last 25 years, lies Aquacomplex, which purifies cellular water* to improve its circulation, restore a youthful appearance and provide skin with powerful age-defying hydration. The first BB Cream infused with Super Aqua-Serum, this true Beauty Balm delivers instant and long-lasting hydration (12 hours)**, smoothes out wrinkles and fine lines, and evens out and enhances 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. *In-vitro tests ** Instrumental test – results 12 hours after application
