Ceramide 3

Ceramide / Barrier Lipid

What is Ceramide 3?

Ceramide 3, or N-stearoyl phytosphingosine, is a lab-made sphingolipid that closely resembles the ceramides abundant in the human skin's outermost layer. Structurally, it features a phytosphingosine base linked to stearic acid, forming a waxy lipid vital to the stratum corneum's mortar-like matrix between cells. In cosmetic formulations, it serves primarily as an emollient and conditioning agent in creams, lotions, and hair treatments. Upon application, it embeds within the skin's lipid bilayers, bolstering the protective envelope that limits water evaporation and blocks external aggressors. This integration aids in preserving the skin's supple texture. For hair, it coats the shaft, minimizing friction for easier styling. Sourced synthetically for purity and stability, it ensures consistent performance across products designed for daily barrier maintenance.
