 Skin-whitening creams identified as containing potentially dangerous levels of mercury continue to be sold online more than seven months after a watchdog group raised the alarm, including on platforms run by eBay, Amazon.com and Alibaba, a Reuters review of the sites shows. The findings come at a time when skin lightening, a multi-billion dollar industry especially popular in Asia, Africa and the Caribbean, is under renewed criticism for promoting light skin as a beauty ideal. Many countries ban or restrict mercury in creams, which can damage the kidneys, brain and nervous system.
