How we scored it
Where it comes from
Manufactured by chemically joining fermentation-derived phytosphingosine with a long-chain omega-hydroxy acid esterified to a fatty acid. The assembly is synthetic but the feedstocks are natural-pattern lipids.
In plain English
A lipid that helps rebuild and strengthen the skin's outer moisture barrier, common in barrier-repair moisturisers. It is made by chemically linking phytosphingosine, a fermentation-derived lipid, with a fatty-acid-esterified long-chain acid.
CosIng definition: Ceramide EOP, formerly known under either of the INCI Names, Ceramide 1 or Ceramide 1 A, is the N-acylated sphingolipid consisting of Phytosphingosine having the D-erythro structure linked to an omega-hydroxy acid which is esterified with a saturated or unsaturated fatty acid.
