I agree the lipstick and makeup controversy over toxin levels needs to be set straight. There is also a component of that which lies on the FDA and Health Canada's shoulders. Health Canada has exhonerated the cosmetics industry to a large degree, which I think is overzealous and the FDA sets acceptable levels that have no real evidence to prove that lead is harmless. Personally I feel lead is bad, bad, bad period. The basics tell us that the body doesn't readily detox or eliminate lead, and that it tends to find it's way into our bones and accumulate there. If I were using lipstick that had lead in it and regularly, like a few times a day - I would look for a new brand. It's pretty simple really - in terms of toxins, I say, "The less, the merrier."
There are lots of other sources where we take lead in - can anyone say 'fill it up' - with leaded gasoline. So, over the years we have been exposed to lead from various sources and it does accumulate - so putting it on your lips in any amount seems rediculous to me.
The article also covers a number of different points and has some interesting links - it is a bit long and if I were editor I would def have said to tighten it up and add a bit more recent science.
Anyway, thanks for your views. B.
