Ingredient callouts

  • Ceramides (phytosphingosine 0.30% - 0.60% and ceramide 3 0.90% - 1.10%). Ceramides are a type of lipids that our skin produces itself. They are a building block of the skin's barrier. Ceramides used in skincare are synthetic or extracted from plants. They work well for softening the skin surface and "patch holes" in the skin's barrier.
  • Peptides (palmitoyl tripeptide-5 0.30% - 0.55%). 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 (biosaccharide gum-1 0.60% - 0.90%, aminobutyric acid 0.65% - 1.00%, sodium acetylated hyaluronate 2.00% - 2.40%, hydrolyzed collagen 2.50% - 3.00% and glycerin 3.10% - 3.80%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
