Petroleum jelly is what makes lip gloss shiny, but it's also a byproduct of oil drilling. Throughout her lifetime, the average woman will inadvertently rub and consume over seven pounds of the gunk. The European Union has banned petroleum jelly products due to cancer concerns. As it turns out, women with breast cancer test for twice the levels of contaminants found in the jelly as cancer-free patients. Overprotective or not, this study shows that the EU ban may save the lives of a lot of women.
