Sphingomyelin is a fat naturally found in cell membranes that may help regulate cholesterol and fat metabolism when consumed through diet. The research suggests dietary sphingomyelin could support skin health and potentially help prevent or manage metabolic issues like obesity and diabetes, though most evidence comes from food science rather than human skin trials.

This is a review article that summarized existing research on sphingomyelin—how it's processed in the body, where it's found in foods, and what studies show about its health effects. It's not a new experiment, but rather an analysis of published findings.
