Ingredient callouts

  • This product also contains Vitamin C (Ascorbic Acid). It can be an effective active for anti-aging and evening out the skin tone, but in this product it is used for stabilizing other ingredients in the formulation. In this concentration (0.20% - 0.40%) it cannot have a noticeable benefit for the skin.
  • Peptides (palmitoyl tetrapeptide-7 0.30% - 0.60% and dipeptide-2 0.30% - 0.60%). 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 (glycerin 4.70% - 5.80%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
