Makeup is meant to enhance your looks. A little mascara, blush and lipstick can do a lot to make you go from drab to fab in no time. Some strategically placed bronzer can even make your face look a little leaner. But could your makeup be making you … fat? Perhaps, if it contains harmful compounds called perfluourochemicals, known as P-F-Cs. A new study published in the Journal of Clinical Endocrinology & Metabolism revealed that P-F-Cs can disrupt thyroid function and contribute to hypothyroidism, a condition with symptoms like fatigue, weight gain, constipation, depression and menstrual irregularities. Sounds like P-M-S but worse.

P-F-Cs are also found in fabrics, carpets, non-stick coating Teflon, fast-food packaging, microwave popcorn bags and paper coatings, such as the material on cash register receipts — almost everything you touch in your day-to-day activities. The study of more than 1,000 people, conducted through the U.S. National Health and Nutrition Examination Survey, found that the higher the level of P-F-Cs in your body, the more likely you are to have hypothyroidism.

And that’s only the beginning of the physical calamities brought on by these chemicals. Recent studies have also found that P-F-Cs and polychlorinated biphenyls, or P-C-Bs, can lower sperm count in men, leading to lower fertility. P-C-Bs are highly prevalent in plastics, prowl the linings of canned goods and are found in their highest concentration in animal fats, despite being banned in 1979. You can remove up to 50 percent of these chemicals from your body in three days by removing visible fat from meat, using fat-reducing cooking methods like grilling or roasting, decreasing consumption of canned goods and storing food in glass instead of plastic.

Staying vigilant about chemicals can keep your body clean and green.
