The study reviewed 32 different lipsticks and lip glosses that you would commonly find in department stores and drug stores.
The study didn't list which products they tested, but they cost between $5.59 and $24.
Scientists analyzed the products for different dangerous metals and found heavy metals like cadmium, chromium, aluminum and manganese.
Cadmium, for instance, is linked to kidney problems.
Lead also showed up in 75 percent of these products.
The study's co-author S. Katharine Hammond says if you keep using these products, health problems could arise.
She advises people to use less product.
The Food and Drug Administration doesn't currently regulate lip products.
Its website refers to previous studies it conducted, which did show evidence of certain metals, but the website added, "We do not consider the lead levels we found in the lipsticks to be a safety concern."
The FDA goes on to state, "We are evaluating whether there may be a need to recommend an upper limit for lead in lipstick in order to further protect the health and welfare of consumers."
You can always check the product packaging.
The website CosmeticInfo.org also allows you to search different products and see what ingredients are in them.
