FYI please find the CBC Story at the following link:

Which includes this quote:

In 2006, the U.S. Food and Drug Administration proposed a ban on over-the-counter sales of skin-lightening products, citing potential health risks of the common ingredient hydroquinone.

Hydroquinone is a possible carcinogen and has been linked with disfiguring condition called ochronosis that causes darkening and thickening of the skin, along with raised bumps and greyish-brown spots.

???? Does anyone know if this applies to developers ????
