Ceramide AP
Ceramide AP, formerly known under the INCI name Ceramide 6 II, is an N-acylated sphingolipid consisting of phytosphingosine having the D-erythro structure linked to an alpha-hydroxy saturated or unsaturated fatty acid (CAS #100403-19-8). It is a type of ceramide that occurs naturally in the upper layer of the skin. Ceramides as a class make up approximately 50% of the lipid matrix between skin cells and play a key role in maintaining the skin barrier and hydration.
Ceramide AP supports a healthy skin barrier by replenishing naturally occurring ceramide lipids found in the stratum corneum. It helps maintain skin hydration by reinforcing the intercellular lipid matrix. Its skin-identical nature makes it well-suited for barrier repair formulations.
