Replenix Restorative Nighttime Bio-Therapy

"Replenix - Restorative Nighttime Bio-Therapy" is a well-rounded moisturizing product. 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. Glycerin, sodium hyaluronate, sodium pca 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). Ceramide 2, ceramide eop, ceramide np, phytosphingosine and cholesterol 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

• As a plus, this moisturizer also contains ceramides (ceramide np 0.55% - 0.85%, ceramide 2 0.30% - 0.50%, phytosphingosine 0.50% - 0.70%, ceramide eop 0.45% - 0.70% and ceramide ap 0.45% - 0.70%). 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 (tetrapeptide-21 0.25% - 0.45%). 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.
