LANEIGE Time Freeze Sleeping Mask revitalizes skin while you sleep. It employs Sleep-Tight Technology, using polymers to visibly soften, smooth, and plump the skin. Dynamic Collagen, with Time Freeze-Centered Technology, targets dryness, uneven texture, fine lines, and other signs of stressed skin. Wake up to a refreshed complexion, as this mask helps boost elasticity and redefine facial contours. A Sleepscent with ylang ylang, rose, and sandalwood further soothes and calms.
