Federal health officials are warning consumers not to use skin creams, beauty and antiseptic soaps, or lotions that might contain mercury.

The products are marketed as skin lighteners and anti-aging treatments that remove age spots, freckles, blemishes and wrinkles, says Gary Coody, national health fraud coordinator in the Food and Drug Administration’s Office of Regulatory Affairs. Adolescents also may use these products as acne treatments, adds Coody. Products with this toxic metal have been found in at least seven states.
