What the product description says

“Hydraphase Intense 24 Hour Rehydrating Face Moisturizer”

Source: Walgreens

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, glyceryl acrylate/acrylic acid copolymer.

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: butyrospermum parkii butter, dimethicone.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: paraffinum liquidum, urea

Butyrospermum parkii butterKey active· Emollient, OcclusiveEffect: HighA great moisturising ingredient that softens the skin and reduces water loss from its upper layer. It also can be helpful in protecting skin from free radicals~3.7–5.5%

GlycerinKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant~3.8–5.7%

Glyceryl acrylate/acrylic acid copolymerKey active· HumectantEffect: HighHelps attract water to the upper layer of the skin and provide a longer-lasting hydration. Can create a thicker product consistency~0.35–0.8%

Hydrolyzed hyaluronic acidKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin. A version of it is naturally present in skin~0.1–0.35%

Also has a positive effect on the skin barrier beyond the humectant action. Can enhance penetration of other ingredients. Is an exfoliating ingredient when used in high concentrations~1.2–1.8%

DimethiconeKey active· Emollient, OcclusiveEffect: HighA silicone that helps to reduce water loss from the surface of the skin. Can temporarily "fill in" lines and wrinkles, absorb oil, and create a nice product finish~2.8–4.1%
