Ceramide EOS

Ceramide EOS is a long-chain, omega-esterified skin-identical ceramide used in cosmetics as a barrier-supporting and skin-conditioning lipid.

What it is

Ceramide EOS is one of the ester-linked omega-hydroxy ceramides, a subclass distinguished by an unusually long fatty acid chain that carries a second fatty acid esterified at its end. In the skin these long-chain esterified ceramides help organize and stabilize the lipid layers of the outermost skin barrier. Added to skincare and sunscreen formulas, Ceramide EOS works alongside other lipids to support a conditioned, comfortable skin surface.

Safety & warnings

Skin-identical ceramides are generally well tolerated and are frequently chosen for products aimed at dry or sensitive skin. They are not recognized fragrance allergens.

Origin & sourcing

Cosmetic-grade ceramides of this type are typically manufactured synthetically or through biotechnological processes to provide a defined, skin-identical molecule.
