Ceramide exists naturally in rice, wheat and other food crops. This ingredient is the main component of the intercellular matrix. 40% to 50% of the sebum in the stratum corneum is composed of ceramide, which is composed of fatty acids and sphingosine. The two are combined with each other in different variants to form 12 types of ceramide. The extraction methods of Ceramide Powder raw materials include chemical synthesis, natural extraction and microbial fermentation.
