Lipstick and glosses may contain potentially harmful levels of metals, a preliminary new study suggests.
A study has raised some issues over the presence of lead in lipstick, but the new research is the first to suggest that many famous lip products also contain cadmium, chromium, aluminum, and other metals, which at some levels may be dangerous.
Study author Katharine Hammond, a professor of environmental health sciences with the University of California Berkley’s School of Public Health, said they “looked at nine heavy metals and found that all of them were present in most of the lipsticks, but not necessarily at really high levels.”
Researchers said that when used on an average rate, around twice per day, the estimated intake exceeded acceptable daily levels for those metals, as presented in past public health studies. In other words, they could pose a potential health risk.
