Sarah Chapman Stem Cell Collagen Activator Duo

"Sarah Chapman - Stem Cell Collagen Activator Duo" has a good moisturizing formula. This moisturizer uses a good combo of humectants and emollients. These both types of ingredients are essentials for improving the skin hydration and keeping the skin barrier healthy. Humectants in this product (acetyl hexapeptide-8, acetyl octapeptide-3, glycerin, imperata cylindrica root extract and sodium hyaluronate) help to increase the water content in the upper layer of the skin. (These ingredients do so by "capturing" water molecules from the outside air or from within the deeper layers of the skin). Palmitoyl tetrapeptide-7, glycine soja protein, caprylyl glycol, pentylene glycol and glyceryl polymethacrylate in this product help decrease the water evoporation from the skin, so that it stays hydrated for longer. These ingredients also soften the skin and take away the feeling of tightness and dryness.

Ingredient callouts

• This moistruizer also contains peptides (palmitoyl tripeptide-5 0.85% - 1.30%, palmitoyl tetrapeptide-7 0.50% - 1.20%, dipeptide-2 0.05% - 0.15%, dipeptide diaminobutyroyl benzylamide diacetate 0.10% - 0.30%, palmitoyl oligopeptide 1.20% - 1.80%, palmitoyl pentapeptide-4 1.20% - 1.90%, acetyl octapeptide-3 1.50% - 2.20% and acetyl hexapeptide-8 1.90% - 2.80%). Peptides is a very big group of ingredients. They all consist of a different combination of amino-acids. Our skin produces peptides naturally. Some of them work as natural anti-biotics, promote wound-healing and production of collagen. The scientists are still studying how effective the topical application of peptides is, but it is very likely that peptides in skincare are helpful. They might be able to support skin barrier restoration and even have an anti-aging benefit. At the very least, they certainly help attract water to the skin and support the hydration in this way.
