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, sclerocarya birrea seed oil.

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: helianthus annuus seed oil, persea gratissima oil.

This product contains antioxidants (tocopherol) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).

The following ingredients - rubus idaeus seed oil also can have an antioxidant effect, but there is less evidence to confirm their effectiveness in skin.
