Last year the U.S. Food and Drug Administration announced that it had found asbestos contamination in eye shadow, face powder and glitter products sold at Claire’s and Justice, two retailers popular with teens and young women. Asbestos is a naturally occurring mineral that can be found in talc. But if asbestos is inhaled, it can lodge in the lungs and do permanent damage, including causing malignant mesothelioma and other forms of cancer. Needless to say, it is not a substance you want in powder form anywhere near your nose or mouth.
