Cosmetic products adulterated with mercury in products marketed for skin lightening and anti-ageing treatments such as freckles, blemishes and wrinkles are not allowed and can cause harm to human health. Exposure to mercury can cause damage to the kidneys and the nervous system. It may also interfere with the development of the brain in unborn children and very young children. Furthermore, exposure to mercury is not only limited to the person using the skin cream containing mercury but also to others especially children as mercury can get into their bodies from breathing in mercury vapours. Infants and children can ingest mercury when they touch the cosmetic products containing mercury or their parents who have used these products. Using products containing mercury can also cause skin rashes, irritation and other changes to the skin.
