Used in skin care formulations for its role in maintaining skin barrier function and promoting hydration. It supports the regeneration of the epidermal layer and helps reduce signs of aging by improving skin elasticity and smoothness. Commonly found in anti-aging creams, serums, and moisturizers. Also utilized in biochemical research to study the role of sphingolipids in cellular signaling pathways, particularly those involved in cell growth, division, apoptosis, and differentiation. Serves as a standard in LC-MS analysis to measure sphingolipids in biological samples such as plasma or tissues, which is crucial for studying metabolic diseases, neurological disorders, and chronic inflammation.
