What the product description says
“SPLASH Absolute Hydration Replenishing Sleeping Pack”
Source: Sephora Hong Kong

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 hyaluronate crosspolymer.

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: chondrus crispus extract, dimethicone.

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~4.4–5.4%

Well-moisturized skin might also be able to repair the sun damage better.This ingredient - beta-glucan - could be helpful for preventing or repairing signs of aging in theory, but there is no evidence that it actually works.
