What the product description says
“Our Restoring Marine Algae Overnight Face Mask deeply hydrates while you sleep to reduce the appearance of fine lines and wrinkles for smoother, healthier-looking skin.”

This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": glycerin, sodium hyaluronate.

When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from within deeper layers of the skin. If the air is dry, humectants can speed up the moisture loss from the skin. This is why it is a good idea to use another product on top of this one to help "seal in" the moisture (look for ingredients like dimethicone, squalane, oils and butters).

    My favorite gel-based overnight mask. I've used it for years and have yet to find one to best it. Great for the price point and consistent. Wake up with glowing and smooth skin every time. Would repurchase and / or recommend.
