What the product description says
“This specially formulated blend of peptides and copper tripeptides helps to hydrate, brighten, and smooth for a healthy, youthful-looking glow.”
Source: Beautylish

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

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).

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: acetyl hexapeptide-8, acetyl octapeptide-3, copper tripeptide-1

Acetyl hexapeptide-8Hero· HumectantEffect: HighA type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles~0.1–0.4%
Acetyl octapeptide-3Hero· HumectantEffect: HighA type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles~0.05–0.2%
Copper tripeptide-1HeroEffect: HighA naturally occurring peptide. One of the most studied peptides in dermatology. It is sometimes abbreviated GHK-Cu. Belongs to the class of carrier peptides. It stimulates both synthesis and breakdown of collagen in skin. It is released in skin wounds and inflammation to support healing. It accelerates wound-healing of the skin and can stimulate hair growth. There are preliminary studies that confirm that copper tripeptide can help support collagen production reducing fine lines and wrinkles and decrease inflammation in skin.~0.01–0.1%
