Judging from the ingredient list, "Bielenda - GOOD SKIN – HYDRA BOOST" works well for improving skin hydration 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. Humectants in this product (glycerin, sodium hyaluronate and trehalose) help to increase the water content in the upper layer of the skin. (These ingredients do so by "capturing" water molecules from the outside air or from within the deeper layers of the skin). Emollients in this formulation (theobroma cacao seed butter, c10-18 triglycerides, cetearyl alcohol, ethylhexyl stearate and glyceryl stearate) help to reduce the moisture loss from the skin. They also soften the skin surface and relieve the feeling of dryness and tightness.

Ingredient callouts

This moisturizer also contains Peptides (copper tripeptide-1 0.55% - 1.25%). 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 they are 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.

What does the product description say?

GOOD SKIN – HYDRA BOOST

Source: From product name

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, 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: theobroma cacao seed butter, c10-18 triglycerides.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: copper tripeptide-1

Irritation risk:Concentration:Effectiveness:HIGH

A naturally occurring peptide. One of the most studied peptides in dermatology. It is sometimes abbreviated GHK-Cu. Belongs to the class of carrier peptides. It stimulates both synthesis and breakdown of collagen in skin. It is released in skin wounds and inflammation to support healing. It accelerates wound-healing of the skin and can stimulate hair growth. There are preliminary studies that confirm that copper tripeptide can help support collagen production reducing fine lines and wrinkles and decrease inflammation in skin.
