What is Bismuth Oxychloride and why is it important to know in makeup? Here is the quick and simple explanation of it.
Bismuth oxychloride is a bi-product of copper and lead refinement, mixed with chloride. Just think about that: why would you ever want something that is a derivative of lead on your face that is mixed with chlorine, which dries you out? It is chemically “heavy”, so it requires buffing to make it stick to the pores of your skin. Therefore, as you may guess, it can lead to clogged pores.
