RE SKIN LIGHTENING:
The FDA have banned 23 more whitening products. Google it. About 17,600,000 results.
The reason cited for the proposed ban is that studies in rodents show "some evidence" that hydroquinone may act as a carcinogen or cancer-causing chemical, although its cancer-causing properties have yet to be proved in humans. Hydroquinone also has been linked with the medical condition known as ochronosis in which the skin becomes dark and thick. Dome-shaped yellowish spots and grayish-brown spots also are observed in ochronosis among black women and men in South Africa, Britain, and the U.S. Ochronosis has been observed in conjunction with hydroquinone use even in persons who have used hydroquinone-containing cosmetics for a short time. Some studies also report abnormal function of the adrenal glands and high levels of mercury in people who have used hydroquinone-containing cosmetics. For these reasons, hydroquinone has already been banned in Japan, the European Union, and Australia. Including BB creams.
Any skin-lightening products containing hydroquinone would be considered new drugs, according to the proposed FDA regulations. The products would require FDA approval before being sold to the public and would only be available with a doctor's prescription.
