DS SPHINGOMYELIN M is a white to off white powder from milk with a characteristic odor. Sphingomyelin is one of the major components of the cell membrane. Under the stimulus of outside environment, sphingomyelin is degraded to ceramide. DS-Sphingomyelin-M protects skin from dryness and helps to maintain skin barrier homeostasis. Also, DS-Sphingomyelin-M is useful as a liposome stabilizer by increasing rigidity of liposome.
