Biotherm - 'Aquasource Spa' Night Mask - 75 ml

You sleep at night, but your skin never stops working. In fact, it works even harder as skin regenerates faster, and loses up to 4x more water.
Discover this new generation bounceback gel texture that self-reforms & creates a natural second skin barrier on skin to lock & replenish skin with plumping moisture all night long. Power regenerator dark cultivated algae produces an extract rich in "skin energy generating molecules" only in the absence of light. On skin, this extract helps boost skin recovery and replenishment. While you sleep, skin bounces back into shape: skin wakes up intensely replenished & plump.
