ABSTRACT Aim: The aim of this study is to examine the levels of heavy metal impurities in various commercially available cosmetic products (eyeshadow and lipstick), specifically to determine the presence and quantities of lead (Pb) and cadmium (Cd), and to evaluate the results in accordance with the Turkish Medicines and Medical Devices Agency Guideline on Heavy Metal Impurities in Cosmetic Products. Considering the potential health risks associated with heavy metal accumulation in cosmetics, the study aims to contribute to the protection of public health. Method: Cosmetic samples from various commercially available brands were obtained and subjected to standard sample preparation procedures. Calibration standards were prepared from certified stock solutions. The quantitative determination of Pb and Cd was performed using Graphite Furnace Atomic Absorption Spectroscopy (GF-AAS) due to its high sensitivity and suitability for tracelevel analysis. Analytical measurements were conducted at element specific wavelengths, and calibration curves with appropriate correlation coefficients were constructed to ensure method accuracy and reliability. Results: Trace levels of Pb and Cd were detected in all analyzed samples. While the concentrations generally remained within ranges considered to represent unavoidable impurities, notable variation among different brands and product types was observed. The analytical method demonstrated acceptable precision and accuracy, as reflected by the performance of the calibration curves and instrumental parameters. Conclusion: The study confirmed the presence of trace amounts of Pb and Cd in both eyeshadow and lipstick samples. Although the detected concentrations were largely below internationally accepted limit values, the potential for cumulative exposure through prolonged or frequent cosmetic use underscores the need for continuous monitoring and stricter quality control measures in the cosmetic industry. These findings highlight the relevance of routine surveillance to ensure consumer safety and regulatory compliance.
