Water Sleeping Mask

What it is

Water Sleeping Mask is a lightweight gel treatment that Laneige places after face cream as an overnight step. The brand highlights squalane, niacinamide, ceramides, and a blend of three types of hyaluronic acid.

Key ingredients

• Three-type hyaluronic acid blend: Laneige says its 3x Hyaluronic Night Blend is intended to provide deeper, longer-lasting hydration. Laneige product page
• Squalane, niacinamide, and ceramides: The brand identifies these as formula ingredients alongside its hydration blend; the product page does not specify a separate effect for each one. Laneige product page

How to use

After face cream, spread the mask evenly over the face. Leave it on overnight and rinse it off in the morning. Manufacturer directions

Who should be careful

The ingredient list includes fragrance, limonene, and linalool. People who avoid fragrance or have known sensitivity to these ingredients may want to review the label before use. This is general ingredient information, not medical advice.

What the brand claims

Laneige says the mask’s light gel formula cools and seals in hydration. The brand reports instrumental measurements in 32 women comparing hydration, elasticity, brightness, and radiance after four versus eight hours of sleep, with one use for each condition. This is a brand-reported result, not our testing. Laneige product information
