Ceramide AS

Ceramide AS

Low hazardMolecular weight no fixed value; d18:1/h18:0 about 582.0

What does Ceramide AS do for skin?

Alpha-hydroxy fatty acid + sphingosine. Related to lamellar packing, but there is little separate clinical concentration data. A possible barrier-lipid contribution is not proof that the single molecule is superior.

Dose on file: N/A; a stand-alone % cannot be fixed from finished-product mixed-lipid evidence alone

  • Dose on file: N/A; a stand-alone % cannot be fixed from finished-product mixed-lipid evidence alone

    Rated on structure and mixed-formulation evidence. The stand-alone clinical effective % is N/A, and 5.0 does not mean better than other lipids.

    • Reference: CIR, 2015
    • Reference: Man et al., 1996
    • Reference: Zettersten et al., 1997
  • Dose on file: N/A; a stand-alone % cannot be fixed from finished-product mixed-lipid evidence alone

    Indirect evidence for a barrier-support purpose. The clinical effective % of this single molecule for treating chronic inflammation in rosacea is N/A.

Red does not mean poison. Preservatives that stop a product going off, UV filters and fragrance can land on yellow or red depending on their score.

Green does not mean right for you. Skin and allergies differ from person to person. Treat the color as a starting point.
