Cosmetics are supposed to ”make people look beautiful”一an action that is both gentle and safe一but sometimes they are the cause of skin problems. For preventing skin problems, we have investigated (1) the actual status of consumer use, (2) the labeling of cosmetics that are being marketed, and (3) the manufacturers of cosmetics themselves. The results of our investigations showed that 247 out of 539 consumers of cosmetics experienced skin problems. If there were labeling on the cosmetics一 such as ”possibility of skin problems”, ”beginning signs of skin trouble”, ”right way to deal with problems”, or ”how to prevent further trouble”一then skin problems could be prevented. Recognizing the liability of manufacturers for their products, we need them to improve their labeling.
