L'Oréal Paris Eye Cream to Reduce Puffiness, Lines and Dark Circles, L'Oreal Paris Skincare Dermo-Expertise Eye Defense Eye Cream with Caffeine and Hyaluronic Acid For All Skin Types

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: glycerin, sodium hyaluronate.

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: simmondsia chinensis seed oil, pentaerythrityl tetraethylhexanoate.

Effective ingredients missing or their concentration is too low.
