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, caprylyl 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: butyrospermum parkii butter, caprylic/capric triglyceride.

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

Caprylic/capric triglycerideKey active· Emollient, OcclusiveEffect: HighA good mix of fatty acids that forms a protective layer on the skin. Improves the shelf life of products. Derived from coconut and glycerin~2.4–2.9%

It can help attract water to the upper layer of the skin. Might to be helpful against acne and clogged pores. Could be helpful in neutralizing free radicals, but solid research is missing~0.15–0.3%
