Physicians Formula Diamond Plumper

Judging from the ingredient list, "Physicians Formula - Diamond Plumper" works well for improving skin hydration As we expect from a proper moisturizer, the formula includes a combo of effective humectants and emollients. These are the two different types of ingredients that are essential for improving the skin hydration and supporting a healthy skin barrier. Sodium hyaluronate, butylene glycol and caprylyl glycol in this product (humectants) attract water molecules to the upper layer of the skin (the water comes from the outside air or from the deeper layers of the skin if the air is dry). Palmitoyl tripeptide-1, cetylhydroxyproline palmitamide, brassica campestris sterols, diisostearyl malate and ethylhexyl palmitate 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-1 0.15% - 0.65%). 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.
