What the product description says
“Formulated with a ceramide complex, peptide complex and amino acids, this lightweight moisturizer hydrates the skin for dewy, plump and radiant looking skin.”
Source: Prequel

This product can help improve hydration of the skin with the two types of ingredients.

The first type is called “humectants”:
these ingredients help attract water. 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. The following ingredients in this product do the job: alanine, arginine.

This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: arginine, squalane.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: ceramide ap, ceramide as, ceramide eop, ceramide np, ceramide ns, hexapeptide-11, palmitoyl tetrapeptide-7, palmitoyl tripeptide-1
