Why are humans so vulnerable to chemicals in cosmetics?
A. The skin is extremely permeable. Cosmetic ingredients most certainly are absorbed through the skin. Some chemicals may penetrate the skin in significant amounts, especially when left on the skin for long periods, as in the case of facial makeup. One study showed that 13 percent of the cosmetic preservative butylate hydroxytoluene (BHT) and 49 percent of the carcinogenic pesticide DDT (which is found in some cosmetics containing lanolin) is absorbed through the skin. Q. What can be done to guard against hazardous cosmetics? A. Choose cosmetics that contain the fewest ingredients; these are still effective. As the list of a product’s ingredients grows, so does the possibility that it will cause adverse reactions, including allergy, irritation, and cancer. Handle all cosmetics in a way that prevents bacterial contamination. Do not leave product containers uncapped. Do not share them. Do not use your fingers instead of applicators.
