Ceramide 1
What is Ceramide 1?
Ceramide 1 belongs to the family of ceramides, which are sphingolipids composed of a sphingosine backbone linked to a fatty acid. It occurs naturally in the stratum corneum, forming part of the lipid lamellae that seal skin cells. In cosmetics, it functions as a skin conditioning agent in moisturizers, serums, and barrier creams, as well as a hair conditioner in select formulations. By embedding into the intercellular spaces, Ceramide 1 replenishes depleted lipids, fortifies the barrier structure, and minimizes water evaporation from the skin surface. This supports overall skin homeostasis, enhances lipid fluidity, and aids in resisting external aggressors like pollutants. Its amphiphilic nature allows compatibility with both oil and water phases in emulsions, making it versatile for leave-on and rinse-off products aimed at hydration and resilience.
