L’Oréal India has rejected claims made by the Maharashtra Food & Drug Administration that several of its skin lightening products contain mercury, according to reports published by The Economic Times and Indian Express.

The French beauty giant is contesting the state regulator’s report, claiming that the methodology used was flawed and has requested a report from Central Drug Laboratory in Kolkata.

“This test report by the Maharashtra FDA is in total contradiction with the test we conducted jointly with them and the numerous tests we have done with independent laboratories in India, France, Germany, Japan and Singapore. Mercury traces were below detectable levels in all of the tests,” a L’Oréal spokesperson said in a statement released to the newspapers.

The Maharashtra FDA claims that mercury at a concentration of 0.02 to 2.38 PPM was found in products manufactured at L’Oréal India’s Pune plant.
