Heavy metals are identified as potential impurities and known by their toxicity. This study aims to evaluate the concentrations of lead (Pb) and cadmium (Cd) in facial cosmetic products marketed in Morocco. The lead and cadmium concentrations were analyzed after mineralization with nitric acid, and the content was determined using differential pulse polarography. The analytical method was validated. Linear calibration curves were obtained for Cd (r² = 0.998), and for Pb (r² = 0.999). For lipsticks just one sample contained lead at 6020 ppm, for foundations one sample contained Pb at 140 ppm, and another sample contained Cd at 50 ppm, for sunblocks just one sample contained Pb at 2350 ppm, and for eye pencils 12 samples contained lead at different concentrations, the median of those being 505 ppm, and just one sample of eye pencil contained Cd at 50 ppm. Comparing our results with the limits recommended in Moroccan regulations, some products are found exceeding these limits. This study showed the presence of heavy metals in some cosmetics. Thus it seems necessary to establish more control in heavy metal levels in cosmetics available on the Moroccan market.
