Product summary

"Dr. LeWinns - Line Smoothing Complex Triple Action Defence" 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 octapeptide-3, glycerin, sodium pca, hydrolyzed soy protein and hydrolyzed wheat protein) 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). Emollients in this formulation (tripeptide-1, ribes nigrum seed oil, cyclopentasiloxane and caprylyl glycol) help to reduce the moisture loss from the skin. They also soften the skin surface and relieve the feeling of dryness and tightness.

Ingredient callouts

  • This moistruizer also contains peptides (tripeptide-1 0.25% - 0.45% and acetyl octapeptide-3 0.20% - 0.40%). 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.
