Ceramide 2
What is Ceramide 2?
Ceramide 2, chemically known as N-stearoyl phytosphingosine, is a synthetic sphingolipid that replicates a key ceramide found in the human skin's stratum corneum. This lipid consists of a phytosphingosine base esterified with stearic acid, making it structurally identical to natural skin ceramides. In cosmetics, it falls under skin conditioning agents and emollients, commonly used in moisturizers, creams, and hair care formulations. It works by embedding into the intercellular lipid lamellae of the skin, reinforcing the barrier structure disrupted by daily stressors like cleansing or weather. This integration aids in locking in moisture and shielding against external aggressors. In hair products, it forms a protective film on the cuticle, smoothing the surface and enhancing tactile qualities without greasiness.
