Based on the ingredients included, "Ren Skincare - Mini Overnight Dark Spot Sleeping Cream" works well for moisturizing the skin. 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 (panthenol, arginine, glycerin, glycogen and sucrose) 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). Arginine, simmondsia chinensis seed oil, squalane, cetearyl alcohol and cetyl alcohol 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 formulation also uses an effective concentration of panthenol (pro-vitamin B5) - about 0.40% - 0.95%. Panthenol helps strengthen the skin barrier, improve hydration and reduce inflammation in skin.
