What the product description says

“Overnight Glow Dark Spot Sleeping Cream”

From product name

This product can help improve hydration of the skin with the two types of ingredients.

The first type is called “humectants”:
these ingredients help attract water. When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from within deeper layers of the skin. The following ingredients in this product do the job: arginine, glycerin.

This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: arginine, simmondsia chinensis seed oil.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: panthenol

Product summary

"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.

Ingredient callouts

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.

This product contains ingredients that could be beneficial, but their concentrations are too low in this formulation: lecithin

Irritation risk
