Guerlain Super Aqua-Mask, x 6 at John Lewis & Partners

This silky-soft sheet mask boasts the latest Aquacomplex Advanced technology, a concentrate of ingredients that promotes the flow of water to the heart of the skin when dehydrated*.

In only 15 mins, the Super Aqua-Mask bathes the skin in intense hydration. With each application, the skin seems protected against the risk of future dehydration, a major cause of skin ageing. Replete with moisture, the hydric support system appears replenished. The skin seems instantly re-plumped and looks rested. Smoothed, its youthful radiance looks restored.
