Cosmetics are health and beauty products such as toothpaste, antiperspirant, lipstick, eyeliner, and hand lotion. Many of us have used one or more of these products every day for many years without giving them a second thought. Recently, some activist groups have claimed that cosmetics pose dangers to our health, and may even be cancer-causing. Since these products are very common, it is important to evaluate the scientific accuracy of these claims. So, before you empty your medicine cabinet of all of that supposedly lethal lipstick, deadly deodorant, and toxic toothpaste, take a moment to consider the facts about cosmetics.
