The invention discloses a method for identifying the authenticity of cosmetics based on a gas chromatography-mass spectrometry (GC-MS) method, which is used for identifying the authenticity of the cosmetics on the basis of qualitative analysis and quantitative analysis. Firstly, layer-by-layer progressive identification is carried out from chromatographic features to mass spectrum features, the principle of'whether all features are all or not 'is followed, as long as one feature cannot be compared, the feature is judged as counterfeit, and then a measured value of the quantitative test raw material content is compared with a raw material content value in a genuine product or a raw material component content in a cosmetic filing system, so that the content of the raw material in the genuine product is determined. If the error range is + / -10%, the product is genuine, otherwise, the product is fake. The method improves the accuracy of cosmetic identification, solves the problems that qualitative analysis technologies such as single appearance identification and pure spectrum identification are easily interfered by impurities and fluorescence, the sensitivity is poor, and cosmetics with complex components cannot be identified, solves the technical problem of cosmetic identification, fills the technical blank of counterfeit cosmetic identification, and has wide application prospects. The method is suitable for true and false identification of components in all cosmetics.
