MAKEUP PRODUCTS (NON-PERMANENT)

While the majority of chemicals in cosmetic products pose limited or zero danger, some are associated to serious medical problems, including cancer, and neurological harm. Cosmetic chemicals can enter a person's body through the skin, inhalation, ingestion and internal use, and pose the same risks as food chemicals, per this site.

Chemicals and contaminants linked to cancer can be found in food and a lot of other common products. Yet, no group of consumer products is subject to less government inspection than cosmetics and other personal care products, including L'Oreal Extra Intense Liquid Pencil Eyeliner. Though most of the chemicals in cosmetics likely present very little risk, being exposed to some is linked to major health problems, such as cancer.
