Works well

This product contains antioxidants (astaxanthin, ubiquinone) 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 - centella asiatica extract, rubus idaeus seed oil, squalene also can have an antioxidant effect, but there is less evidence to confirm their effectiveness in skin.

Moisturizing
Side benefit · Palmitoyl tripeptide-5, Opuntia ficus-indica seed oil + 11 more
Works well

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: lactobacillus ferment, sodium hyaluronate.

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: squalene, argania spinosa kernel oil.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: palmitoyl tripeptide-5
