C22 Ceramide (d18:1/22:0) is widely used in skincare and cosmetic products due to its ability to strengthen the skin barrier and retain moisture. It helps in restoring the natural lipid balance of the skin, making it effective for treating dry, irritated, or aging skin. Additionally, it is utilized in research to study cellular signaling pathways, particularly those related to apoptosis and cell differentiation. Its role in maintaining cellular integrity also makes it valuable in dermatological studies and therapeutic formulations for skin disorders.
