What the product description says

“Waso: SHIKULIME Mega Hydrating Moisturizer”

Source: Allbeauty

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: erythritol, glycerin.

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, squalane.

TrehaloseKey active· HumectantEffect: HighA sugar that attracts water to the upper layer of the skin~0.45–0.65%
