Synopsis Objective The objective of this study is to create and establish a simple and rapid method for lipid evaluation in daily‐use female products, namely lipsticks. Methodology This approach uses STE‐LDI‐MSI for fast fingerprinting of complex lipids, such as triacylglycerols, phosphoglycerols and simpler structures as free fatty acids. Results This work has focused on lipsticks of several brands globally marketed. With no sample preparation, it has demonstrated to readily identify compounds of interest by integrating both full scan and MS/MS data. Conclusion A novel and rapid technique for lipid evaluation in lipsticks is presented. Résumé Objectif Créer et mettre en place une méthode simple et rapide pour l'évaluation des lipides dans les produits d'usage quotidien pour femmes, notamment les rouges à lèvres. Methodologie Cette approche utilise STE‐LDI‐MSI pour une caractérisation rapide des lipides complexes, tels que les triglycérides, phosphoglycérols et des structures plus simples comme les acides gras libres. Résultats Ce travail a porté sur les rouges à lèvres de plusieurs marques commercialisées au niveau mondial. En l'absence de préparation de l'échantillon, il démontré la capacité à identifier facilement les composés d'intérêt en intégrant à la fois l'analyse complète et de données MS / MS.
