Peptides (palmitoyl tripeptide-1 0.05% - 0.25%, palmitoyl tetrapeptide-7 0.10% - 0.35% and palmitoyl dipeptide-5 diaminobutyroyl hydroxythreonine 0.20% - 0.70%). Peptides are a very big group of ingredients. They all consist of a different combination of aminoacids. Our skin produces Peptides naturally. Some of them work as natural antibiotics, promote wound-healing and production of collagen. The scientists are still studying how effective the topical application of Peptides is, but it is very likely that theynare helpful. Peptides might be able to support skin barrier restoration and even have an anti-aging benefit. At the very least, they certainly help attract water to the skin and support the hydration in this way.
Humectants (hyaluronic acid 0.40% - 0.90% and glycerin 3.80% - 5.70%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

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, hyaluronic acid.

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: palmitoyl tetrapeptide-7.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: palmitoyl dipeptide-5 diaminobutyroyl hydroxythreonine, palmitoyl tetrapeptide-7
