On March 10, the ZMWG published the results of a new study demonstrating that skin lighteners containing mercury are still being sold online, despite bans and safety concerns. Ebay, Amazon, Shopee, Jiji, and Flipkart are among the websites still selling high mercury–containing skin lightener products. Some of them were the same offenders selling the banned products in 2019. Of the 271 online products tested from 17 countries, nearly half contained over 1 ppm of mercury, which is the legal limit that has been established by most governments and the Minamata Convention on Mercury. Based on their packaging, the majority of these products were manufactured in Asia, most often in Pakistan (43%), Thailand (8%), China (6%), and Taiwan (4%), according to the report.

In ZMWG’s prior publications, mercury concentrations reported in some of these products ranged from 93 ppm to over 16,000 ppm. Even higher concentrations have been reported by other entities. And according to a World Health Organization November 2019 report, mercury-containing skin lightening products have been manufactured in many countries and areas, including Bangladesh, China, Dominican Republic Hong Kong SAR (China), Jamaica, Lebanon, Malaysia, Mexico, Pakistan, Philippines, Republic of Korea, Thailand, and the United States. According to the ZMWG, 137 countries have committed to the Minamata Convention to phase out and limit mercury, including in cosmetics.
Despite bans on some of these products, consumers in the United States and other countries with bans and restrictions are still at risk of exposure to mercury-containing skin lighteners because of online sales. Hopefully, the work of the ZMWG and similar entities will continue to help limit potentially harmful exposures to mercury, while maintaining access to safe and effective methods to treat hyperpigmentation.
