Test Your Lipstick For Dangerous Lead

Many women don't realize that when they're putting on their favorite lipstick each morning, it can be bringing them one step closer to lead poisoning. This guide will help you check to see if your lipstick contains lead.

Rub a small amount of lipstick across a part of open skin, preferably your hand.
Wipe a gold ring [or any jewelry made of gold] on it.
NOTE: "This claim appears to be drawn from an old alchemist's trick of testing the purity of gold by rubbing ore on a dark stone (often containing lead) and comparing the streak with another of known quality. However, the process does not work in reverse. Even if it did, there would not be a large enough concentration of lead in a strip of lipstick to produce a visible change.

Real, reliable detection of lead in a product requires rigorous scientific testing, and cannot be achieved "on the cheap" using normal household products."

Wait for about a minute or two. If the color turns black, then immediately throw the lipstick away. The lipsticks that you want to test are old ones, they don't make lipstick with lead anymore, but many from years past can be very dangerous.
If there is no color change, then your lipstick is fine. This part is very important, you must check with your other lipsticks and follow this process again. If you have any lipsticks from 5 years and older, throw them out! Even if they do not have lead, they may have bacteria which is common with old makeup including lipstick, eyeshadow and particularly mascara.

The lipstick will not turn black immediately. If it doesn't change within a minute or so, then it is fine.

Saint Laurent contains a considerable amount of lead.
Some mac lipsticks have lead too..
