What it is
This ingredient is a lipid-based pseudo-ceramide engineered to mimic the structure and function of the skin's natural ceramides. It is incorporated into formulas to support a smooth, conditioned skin feel and to complement the skin barrier, and it is associated with barrier-focused Korean skincare and sun care brands. In sunscreens it contributes to the lipid phase and a comfortable after-feel.
Safety & warnings
As a synthetic lipid used at modest levels, it is generally well tolerated and is not a recognized fragrance allergen. Sensitivity data are limited but it is broadly considered low-irritation.
Origin & sourcing
Synthetic; produced as a designed ceramide analog rather than extracted from skin or plants.
