What the product description says
“is a brightening eye treatment, infused with vitamins and peptides, provides immediate and long-term hydration.”
Source: SkincareRX

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: cyclomethicone, 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: butyrospermum parkii butter, dimethicone.

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

Product summary

Based on the ingredients included, "Kerstin Florian - Brightening Eye Creme" works well for moisturizing the skin. This moisturizer uses a good combo of humectants and emollients. These both types of ingredients are essentials for improving the skin hydration and keeping the skin barrier healthy. Cyclomethicone, glycerin, glyceryl acrylate/acrylic acid copolymer, saccharomyces/copper ferment and saccharomyces/iron ferment in this product (humectants) attract water molecules to the upper layer of the skin (the water comes from the outside air or from the deeper layers of the skin if the air is dry). Palmitoyl tetrapeptide-7, cholesterol, cyclomethicone, butyrospermum parkii butter and dimethicone in this product help decrease the water evoporation from the skin, so that it stays hydrated for longer. These ingredients also soften the skin and take away the feeling of tightness and dryness.

Ingredient callouts

  • This moistruizer also contains peptides (palmitoyl tetrapeptide-7 0.35% - 0.60% and palmitoyl oligopeptide 0.40% - 0.60%). Peptides is a very big group of ingredients. They all consist of a different combination of amino-acids. Our skin produces peptides naturally. Some of them work as natural anti-biotics, 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 peptides in skincare are helpful. They 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.
