If you have acne, and are worried about benzene because corporate media is touting that an "independent" lab - which happened to be paid by a group representing lawyers who want to sue - found elevated levels of it, you can relax.
In 2018, an International Agency for Research on Cancer did discuss benzene, but the levels were 10,000X safe levels. And they do not ever show what causes cancer, all they do is target chemicals and look at rows and columns of data from surveys and other papers, and try to claim correlation.
