L’Oréal Paris Revitalift Classic Brightening Sheet Mask is a naturally sourced Japanese cotton fabric mask designed to deliver a more concentrated dose of active ingredients into the skin. With only 0.3mm thickness, it fits perfectly to the contours of the face, locking the serum into the skin for a luminous brightening effect. Enriched with brightening serum and volcanic spring water, this mask helps the skin look rested, fresher and glowing.
