Ingredient callouts

  • Ceramides (ceramide ng 0.20% - 0.40% and ceramide np 0.20% - 0.35%). Ceramides are an important part of our natural skin barrier. The Ceramides used in skincare are synthetic or come from plants. They help soften the skin and can help "fill the gaps" in the skin barrier, keeping the skin hydrated and resilient for longer.
  • Peptides (acetyl tetrapeptide-15 0.10% - 0.15%). 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 (mannitol 0.25% - 0.45%, sodium hyaluronate 0.25% - 0.45%, panthenol 0.30% - 0.55% and glycerin 2.50% - 3.00%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
