Ceramides have proven anti-aging properties. If we compare bricks and cement, skin cells are the bricks and ceramides are the cement. Ceramides hold the different elements of the skin together and form a protective layer to help prevent dehydration and protect against external aggressions.
There are two other fascinating ingredients in the skin: phytosphingosine and sphingolipids. These are precursors to ceramides: they help the upper layers of the skin to produce more ceramides, so that it protects itself better. Applying a ceramide skin care product helps regenerate the skin's ceramides. They help the skin to be better hydrated, firmer and more supple.
