What This Ingredient Does

Ceramide AP is one of the ceramides naturally found in the skin barrier. It helps maintain the structure and integrity of the outer skin layer, preventing moisture loss and protecting against external irritants.

Topically, it supports barrier repair by replenishing depleted lipids and improving the skin’s ability to retain hydration. It works effectively alongside humectants like glycerin, hyaluronic acid, and sodium hyaluronate, which draw moisture into the skin while ceramides help lock it in.
