The study looked at heavy metals in cosmetic products in Nigeria to see if they could harm people. They found that the levels of heavy metals were generally low and unlikely to cause health problems for users. The order of metal concentrations was iron, copper, zinc, manganese, chromium, cadmium, and lead. Overall, the amount of metals people could be exposed to from these products was below safe limits set by experts. So, using these cosmetics is not likely to pose a significant health risk, whether for cancer or other health issues.
