Quick Summary

Ceramides are lipid ingredients used in moisturizers to support the feel of the skin barrier and help dry-looking skin look smoother and less flaky.

What It Is

Ceramides are part of the skin’s natural lipid mix. Product labels may name specific forms such as Ceramide NP, Ceramide AP, or Ceramide EOP, but this page keeps them under the consumer parent Ingredient Ceramides.

Mechanism

A simple way to picture ceramides is the brick-and-mortar model: skin cells are the bricks, and lipids help fill the spaces between them. In cosmetic moisturizers, ceramides fit the barrier-support side of dry-skin care rather than the water-attracting side.
