Ceramide NP (0.01%)
Ceramide NP (also known as Ceramide 3) is an N-acylated sphingolipid consisting of phytosphingosine with the D-erythro structure linked to a normal saturated or unsaturated fatty acid (CAS #72968-43-5). It is one of many ceramide types found naturally in the uppermost layer of the skin. Ceramides collectively make up approximately 50% of the intercellular lipid matrix between skin cells. It is officially classified by CosIng as a hair conditioning and skin conditioning ingredient.
Ceramide NP plays an important role in maintaining a healthy skin barrier and keeping the skin hydrated. Research indicates it acts synergistically with Ceramide 1 to improve skin hydration and reduce transepidermal water loss, particularly on surfactant-irritated skin.
