What the product description says
“Infused with purifying zinc oxide and hydrating olive leaf extract, its powdery-gel texture melts effortlessly onto the face to smoothen the look of enlarged pores, whilst eliminating excess oil and shine on the T-zone (forehead and nose) and U-zone (cheeks and chin).”

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: sodium hyaluronate, butylene glycol.

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: dimethicone, cyclopentasiloxane.

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~6.4–9.6%
PolymethylsilsesquioxaneKey activeEffect: HighA silicone that improves product texture and helps dissolve other ingredients. Can form a non-greasy film on the skin to prevent moisture loss~1.2–1.8%
Sodium hyaluronateKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin~0.1–0.4%
CyclopentasiloxaneKey active· EmollientEffect: MediumA silicone that helps improve the product texture and spreadability. Can absorb oil creating a short-term mattifying effect on the skin~5.1–7.6%
Stearyl glycyrrhetinateKey activeEffect: MediumA fatty acid derived from licorice. Works as an emollient and can help calm down inflammation~0.3–0.75%
Butylene glycol· HumectantEffect: LowUsed to create a nice product texture and help delivery of other ingredients. Might be somewhat helpful in attracting water to the upper layer of the skin~0.15–0.55%
