Lipid molecules that fill the spaces between skin cells. Replenishing them supports a damaged or aging barrier.
What it does
Ceramides make up about half of the skin's intercellular lipids; they decline with age and are stripped by harsh cleansing or active ingredients. Topical ceramides — especially in a 3:1:1 ratio with cholesterol and fatty acids — replenish the barrier.
