Cholesteryl/Octyldodecyl Lauroyl Glutamate

Cholesteryl/Octyldodecyl Lauroyl Glutamate is a synthetic ingredient derived from cholesterol and amino acids. It's designed to mimic the structure of natural ceramides—lipid molecules that form a crucial part of the skin's barrier. This ingredient belongs to a class called lipo-amino acids, which combine fatty acid and amino acid chemistry to create compounds that behave similarly to the skin's own moisturising components.In formulations, it functions as a skin conditioning agent. Its lamellae-forming properties (ability to create layered structures) allow it to integrate into the skin's u…

This ingredient works by integrating into the lipid matrix of the skin's outermost layer (stratum corneum). Because its molecular structure resembles ceramides, it can slot into the organised, layered arrangement of fats that cement skin cells together. This integration helps seal in moisture and strengthens the barrier against external irritants.The lamellae-forming structure is key: it creates microscopic organised layers that function like a moisture-holding scaffold, reducing the amount of water that evaporates from the skin's surface.

This ingredient is typically found in moisturisers, serums and barrier-repair formulations. It works well as part of a regular skincare routine and integrates effectively with other hydrating or barrier-supporting ingredients. Apply to clean skin, morning and evening, as directed by your product's instructions. There is no evidence of a need to cycle or rotate its use.

This ingredient is generally well-tolerated and is considered safe for topical skincare use. Those with very severe atopic dermatitis or compromised skin should patch-test first, though it is specifically designed for sensitive and reactive skin types.
