What does the product description say?
"Powered by a 7x concentration of the brand’s Matrixyl 3000 PlusTM peptide, the serum works to replenish moisture below the skin surface in order to plump out lines and refine its texture."
WIMJ summary

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: glycerin, sodium lactate.

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: palmitoyl tetrapeptide-7, caprylyl glycol.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: acetyl dipeptide-1 cetyl ester, palmitoyl tetrapeptide-7
