Watchout women! Your favourite red lipsticks that make you look attractive, composed, sexy and ready to take on the world, may in fact be causing you more harm than good.
Last year, the US Food and Drug Administration conducted tests on 22 red lipsticks and found lead, a neurotoxin, in every single lipstick sample studied.
The highest levels were in three well-known and common brands: over Girl, Revlon, L'Oreal.
The FDA does not regulate lead in finished cosmetics, only in colours added to the products.
None of the products exceeded the 20 parts per million limit on colours, the agency said.
An industry trade group, the Personal Care Products Council, said manufacturers did not add lead intentionally.
"Because lead is found naturally in air, water, and soil, it may also be found at extremely low levels as a trace contaminant in the raw ingredients used in formulating cosmetics, just as it is in many thousands of other products," the Sydney Morning Herald quoted the group as stating.
The Campaign for Safe Cosmetics is, however, not convinced.
It is calling on the FDA to require cosmetics manufacturers to reduce lead to the lowest achievable levels.
