What the product description says
“A mask that is effective for soothing rough skin and dry skin, for moisturizing and moisturizing skin with one sheet.”
Source: Yesstyle

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

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).

This product contains antioxidants (camellia sinensis leaf extract) that might be able to help neutralize free radicals in skin to lessen the damage it gets from the UV light (sun). There is not enough evidence to confirm their effectiveness in skin though.
