Ingredient callouts

  • Peptides (palmitoyl tripeptide-1 0.20% - 0.35% and palmitoyl tetrapeptide-7 0.20% - 0.35%). 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.
  • Adenosine 0.15% - 0.25%. It is a compound that in involved in many biological processes inside the skin cells. According one high-quality clinical trial, topical Adenosine in low concentrations can somewhat help improve "deep wrinkles" - the wrinkles that appear with age in places where our faces are most dynamic (for example, on the forehead or in the corners of the eyes).
  • Humectants (sodium lactate 0.15% - 0.30%, panthenol 0.15% - 0.30%, sodium pca 0.15% - 0.30%, sodium hyaluronate 0.15% - 0.30%, yeast extract 0.15% - 0.25%, pca 0.15% - 0.30%, histidine 0.15% - 0.25%, glycine 0.15% - 0.25%, calcium pca 0.15% - 0.25%, aspartic acid 0.15% - 0.25%, arginine 0.10% - 0.25%, alanine 0.15% - 0.25%, glycerin 0.15% - 0.25%, panthenol 0.35% - 0.60% and glycerin 4.80% - 5.90%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
