What could be more harmless than a little shine on your rosy lips? Well, as it turns out, lots of things, because the shine in lip gloss comes from petroleum jelly. Petroleum jelly is a byproduct of oil drilling, and when you spread it on your lips, you end up eating it, which is essentially the same as drinking gasoline. Add up the amount of lip gloss the average woman uses (and consumes) over a decade, and it equals 7 pounds. The European Union has banned many petroleum jelly products, and experts are concerned they could be linked to cancer. Women with breast cancer have twice the levels of hydrocarbons (substances found in petroleum jelly) in their breasts than women who haven't had breast cancer.”
