Product summary

"Replenix - Enriched Nighttime Bio-Therapy" is a well-rounded moisturizing product. The formulation is based on a combination of good humectants and emollients. Both are needed to increase the skin hydration level. Glycerin, sodium hyaluronate, butylene glycol 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). Emollients in this formulation (ceramide 2, ceramide eop, ceramide np, phytosphingosine and cholesterol) 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

  • As a plus, this moisturizer also contains ceramides (phytosphingosine 0.45% - 0.65%, ceramide np 0.60% - 0.85%, ceramide eop 0.45% - 0.70%, ceramide ap 0.45% - 0.70% and ceramide 2 0.40% - 0.65%). 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.
  • This moistruizer also contains peptides (tetrapeptide-21 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.
