NIA24 Skin Strengthening Complex

"NIA24 - Skin Strengthening Complex" 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 (glycerin, sodium hyaluronate, sucrose, hydrolyzed soy protein and butylene glycol) 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). Ceramide 2, ceramide 3, carthamus tinctorius seed oil, oenothera biennis oil and triticum vulgare germ 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 moisturizer includes a form of retinoids (vitamin A) - retinyl palmitate 0.25% - 0.45%, but this type of vitamin A is not very effective. It could in theory help with fine lines and wrinkles, but the effect is most likely minimal.
• As a plus, this moisturizer also contains ceramides (ceramide 3 0.30% - 0.55% and ceramide 2 0.30% - 0.55%). Ceramides are a type of lipids that our skin produces itself. They are a building block of the skin's barrier. Ceramides used in skincare are synthetic or extracted from plants. They work well for softening the skin surface and "patch holes" in the skin's barrier.
• We like that this moisturizer contains peptides (palmitoyl hexapeptide-12 0.25% - 0.50%). There are many different kind of peptides and they are naturally present in our skin. They all are a combination of amino-acids. Some of them work as natural anti-biotics, promote wound-healing and production of collagen. The science is still not settled on how effective peptides in skincare are, but it is very likely that they have a benefit. Peptides might help restore the skin barrier and fight the signs of aging. At the very least, peptides work as humectants: they attract water to the upper layer of the skin and improve its hydration.
