There is a problem of how much lead and mercury is contained in cosmetics, and regular manufacturers will strictly control the content of lead and mercury.
Twenty or thirty years ago, cosmetics that deliberately added toxic ingredients such as heavy metals led to serious exceedances of heavy metals did exist, but now with the strengthening of national supervision of cosmetics, such problems have rarely occurred. Nowadays, there is a practice of using silver and water to test whether cosmetics contain heavy metals, and there is a way to say that cosmetics can be applied to the back of the hand, and rubbed repeatedly with silverware, if ** turns black, it means that it contains heavy metals. There is also a method that if the cosmetics are poured into the submitted water, if they sink, it means that they contain heavy metals.
This test method is not scientific, maybe some simple chemical reactions can be preliminarily judged, but if the content of heavy metals in cosmetics is small, then the measured results will not be accurate, let alone determine whether the heavy metal content exceeds the standard. Science brings us advanced products, and the concept of our consumers should also keep up with the pace of science and technology, and use scientific methods and attitudes to understand cosmetics. Nowadays, there are relevant instruments for the detection of cosmetics, and the test results are very detailed and accurate, but the testing cost is relatively expensive.
