L'ANZA Keratin Healing Oil Smooth Down Spray

Judging from the ingredient list, "L'ANZA - Keratin Healing Oil Smooth Down Spray" 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. Humectants in this product (magnesium pca, manganese pca, sodium pca and zinc pca) 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). Astrocaryum murumuru seed butter, helianthus annuus extract and helianthus annuus seed oil 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 tetrapeptide-17 4.70% - 7.00%). 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.
