What it is
Ceramide 1, now more often designated Ceramide EOP under updated nomenclature, is one of the ceramide lipids that are naturally present in the outer layer of skin. In cosmetics it is used as a skin-conditioning agent intended to complement the skin's own lipids and support a smooth, comfortable feel. It is oil-soluble and is typically incorporated into the lipid phase of emulsions, often alongside other ceramides, cholesterol, and fatty acids.
Safety & warnings
Ceramides are well tolerated and skin-identical, making them suitable for sensitive and dry skin; they are not recognized fragrance allergens and are used at levels that do not present comedogenicity concerns.
Origin & sourcing
Ceramides used in cosmetics are typically produced synthetically to match the structure of skin-identical lipids.
