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. Enriched with the benefits of Aquacomplex, Super Aqua-Serum is reinventing itself to offer the skin a new anti-wrinkle hydrating power. The skin is deeply hydrated and more resistant to the effects of time. Its wrinkles and fine lines are visibly plumped up. It is smoothed and recovers its radiance, freshness and plumpness.
