This is the first I have heard of lead in lipstick and I don't know if it is
reliable information. But here it is just in case:

Lead in lipstick, etc.

Even lipstick isn't safe anymore. Recently a brand called "Red Earth"
decreased their prices from $67 to $9.90. It contained lead. Lead is a
chemical
which causes cancer, and brain and nerve damage, etc.

The brands which contain lead are:

I. CHRISTIAN DIOR
2. LANCOM E
3. CLINIQUE
4. Y.S.L
5. ESTEE LAUDER
6. SHISEIDO
7. RED EARTH (Lip Gloss)
8. CHANEL (Lip Conditioner)
9. MARKET AMERICA-MOTNES LIPSTICK.

The higher the lead content, the greater the chance of causing cancer and
other damage. After doing a test on lipsticks, it was found that the Y.S.L.
lipstick contained the most lead. Watch out for those lipsticks which stay on
longer. If your lipstick stays longer, it is because of the higher content of
lead.

Test for yourself:

1. Put some lipstick on your hand.
2. Use a Gold ring to scratch on the lipstick.
3. If the lipstick color changes to black then you know the lipstick contains
lead.
