“A powerful hydrator for the skin's surface, Polyglutamic Acid can hold 4x more moisture than Hyaluronic Acid, locking in moisture and helping the skin appear instantly smoother.”
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, polyglutamic acid.
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: dimethicone, bis-peg-12 dimethicone.
