"Ren Skincare - Overnight Glow Dark Spot Sleeping Cream" has a good moisturizing formula. 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. Panthenol, arginine, glycerin, glycogen and sucrose 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). 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.
There are quite a few common irritants in this product, including ingredients without particular skin benefits. We would not recommend it for sensitive skin. We assess the overall irritancy of this moisturizer to be high. For a detailed overview of all potential irritants: click here
