RE: Lipstick
Have you found how much lead it takes to damage the human body or cause birth defects?
I usually like to know about how much or in what concentration a substance has to occur, and how, before I freak about it being in a product I use.
I tend to either tint my home made lip gloss, but if determined to use lipstick, I don't worry about its lead content. I am past my reproductive years and, if I remember correctly, lead effects children more than adults.
I could be mistaken, though..
