L’Oréal Paris Revitalift Filler [HA] Plumping 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 plumping effect. Enriched with Hyaluronic Acid and Damask rose, this mask helps the skin feel hydrated, smooth and more radiant.
