Why does lipstick contain lead?
Lead is a considered to be a contaminant in lipstick, and therefore it is not listed on labels. Lipstick can become contaminated with lead in two ways: raw materials used in the lipstick may be contaminated with lead, or the pigments (paints) used in the lipstick contain lead. FDA noted that the lipsticks containing the most lead came from three manufacturers. The CSC study also found that a few manufacturers consistently had the highest lead levels. This indicates that some companies are using better manufacturing practices than others.
