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 (0.25% - 0.45%) it cannot have a noticeable benefit for the skin.
  • This product includes a form of Retinoids (vitamin A) - retinyl palmitate 0.25% - 0.40%, but this type of vitamin A is not very effective. It could in theory help with fine lines and wrinkles, but the effect is most likely minimal.
  • Peptides (palmitoyl tripeptide-1 0.30% - 0.55%, trifluoroacetyl tripeptide-2 0.25% - 0.50%, palmitoyl tripeptide-5 0.25% - 0.50%, dipeptide diaminobutyroyl benzylamide diacetate 0.30% - 0.55%, hexapeptide-11 0.30% - 0.55%, palmitoyl tetrapeptide-7 0.45% - 0.65%, tripeptide-1 0.45% - 0.65%, acetyl tetrapeptide-2 0.40% - 0.65%, acetyl tetrapeptide-9 0.40% - 0.65%, palmitoyl oligopeptide 0.55% - 0.85%, acetyl hexapeptide-1 0.50% - 0.75%, acetyl hexapeptide-8 0.55% - 0.80%, acetyl tetrapeptide-11 0.65% - 1.00%, palmitoyl hexapeptide-12 0.95% - 1.15%, acetyl octapeptide-3 1.10% - 1.40% and tripeptide-10 citrulline 1.40% - 1.70%). 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 (sodium lactate 0.25% - 0.45%, dextran 0.25% - 0.45%, sodium hyaluronate 0.25% - 0.45%, acetyl hexapeptide-8 0.55% - 0.80%, acetyl octapeptide-3 1.10% - 1.40%, mannitol 2.30% - 2.80% and glycerin 4.40% - 5.40%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
