This product has a pure active ceramide concentration of 0.3%. Ceramide Complex is a term used by brands to either hide the ceramide concentration or inflate the concentration percent. Ceramide Complexes are blends of ceramides provided by raw material suppliers along with other ingredients (like emulsifiers, preservatives, etc) and contain around 2.5% ceramide or lesser. Using a 1% concentration of this complex delivers ceramides in the range of 0.025%. We have formulated this product to deliver a high concentration of pure ceramide (0.3%) to deliver maximum benefits to the skin.
