What the product description says

“Face 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

Based on the ingredient list, "Ren Skincare - Face Overnight Glow Dark Spot Sleeping Cream" can work well for skin moisturization. This moisturizer uses a good combo of humectants and emollients. These both types of ingredients are essentials for improving the skin hydration and keeping the skin barrier healthy. 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). Emollients in this formulation (arginine, simmondsia chinensis seed oil, squalane, cetearyl alcohol and cetyl alcohol) 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

Panthenol (pro-vitamin B5) at about 0.40% - 1.00% concentration. In this concentration, Panthenol works effectively to improve the skin barrier and reduce inflammation.

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