Ingredient callouts

  • Ceramides (caprooyl sphingosine 0.30% - 0.50%, caprooyl phytosphingosine 0.30% - 0.55%, ceramide eos 0.30% - 0.50%, ceramide eop 0.30% - 0.55%, ceramide ap 0.30% - 0.50%, ceramide ns 0.30% - 0.55% and ceramide np 0.30% - 0.60%). 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 (nonapeptide-1 0.30% - 0.50%). There are many different kind of Peptides and they are naturally present in our skin. They all are a combination of aminoacids. Some of them work as natural antibiotics, promote wound-healing and production of collagen. The science is still not settled on how effective Peptides are in skincare, but it is very likely that they have a benefit. They might help restore the skin barrier and fight the signs of aging. At the very least, Peptides work as humectants: they attract water to the upper layer of the skin and improve its hydration.
  • Humectants (histidine 0.30% - 0.50%, arginine 0.30% - 0.55%, alanine 0.30% - 0.55%, aspartic acid 0.30% - 0.55%, glutamic acid 0.30% - 0.55%, glycine 0.30% - 0.50%, polyglycerin-3 0.30% - 0.55%, carnosine 0.30% - 0.50%, betaine 0.50% - 0.75% and glycerin 5.10% - 6.20%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
