Created using advanced microfluidic technology, Chanel Hydra Beauty Micro SERUM offers extraordinary hydration and sensoriality. This ultra-light serum strengthens skin's barrier function and locks in moisture for up to 24 hours.* The complexion looks plump, rebalanced and glowing. For the first time, the formula is infused with two types of micro-bubbles, which preserve the ingredient's purity until application. Blue bubbles containing camellia oleo-extract intensely hydrate and restore the look of volume to skin's uppermost layers, while clear bubbles containing camellia oil deliver nourishing benefits.
