Hydroquinone is a topical agent for reducing skin pigmentation. Hydroquinone was banned in January 2001 in cosmetics because of the potential damage it can do to the skin in terms of irritating the skin and creating white areas where no pigment can be made or in some cases turning the skin black. Recent studies have shown the potential of hydroquinone to cause cancer.
Hydroquinone has been known to cause blood cancers such as Leukemia and Kidney damage in animal studies. When applied to the skin it is absorbed into the blood stream and excreted via the kidneys but at a slower rate. This tells us that hydroquinone accumulates in the body. It is broken down in the bone marrow to p-benzoquinone and this is where long term damage may originate.
That is true. I just found out myself that hydroquinine is a *benzene* derivative. Benzene is definitely known to be one of the things that can cause blood cancers, like multiple myeloma and leukemia. So I would be wary of it. Maybe google some organic skin products that help with lightening.
I found this article on hydroquinone from Paula Begoun. "As for hydroquinone being linked to leukemia, the link has to do with the chemical benzene, which can be metabolized into hydroquinone. It’s the benzene as the starting point that’s cause for concern, not hydroquinone as it is used in topical skin lightening products."
There has not been documented case of cancer of people using hydroquinone.
