La Roche-Posay Substiane Anti Aging Eye Cream

"La Roche-Posay - Substiane Anti Aging Eye Cream" has a good moisturizing formula. To work well, any moisturizer needs to include a combination of water-binding and emollient ingredients. La Roche-Posay - Substiane Anti Aging Eye Cream ticks this box. Humectants in this product (glycerin and bis-peg-18 methyl ether dimethyl silane) 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). Prunus armeniaca kernel oil, beeswax, butyrospermum parkii butter, cera alba and dimethicone 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 (acetyl dipeptide-1 cetyl ester 0.15% - 0.30%). 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.
