Hong Kong's Consumer Council conducted tests on approximately 30 lipstick samples and found that 60 percent of them contained elevated levels of cobalt, while 40 percent contained nickel, both known allergenic heavy metals. Brands such as Chanel, Giorgio Armani, Estee Lauder, and others were found to have heightened levels of these metals, causing skin irritations. The council recommended that manufacturers pay close attention to raw materials potentially containing allergenic heavy metals and minimize their use. Some brands defended the safety of their products, while others expressed a willingness to address allergy-causing substances. The council advised consumers to discontinue use if they experienced skin reactions and cautioned against ingesting substances by wiping off lipstick before eating or drinking.
