Does hydroquinone really cause cancer in humans?
According to Dr. Susan C. Taylor, M.D., a Philadelphia-based dermatologist in this monthâ€2122s Elle magazine,â€The maximum levels of hydroquinone currently allowed (2 percent for over the counter, 4 percent for prescription) arenâ€2122t dangerous. At worst, it might cause redness or irritation, but only if your skin is sensitive or allergic to the medication.†And in a 2006 review in the Journal of the American Academy of Dermatology, Dr. Jacob Levitt, M.D. reports that topical applications of hydroquinone in standard product concentrations are not carcinogenic to humans. According to Dr. Levitt, use of hydroquinone in murine (mouse) studies led to an actual decrease in murine hepatocellular carcinomas (cancerous liver tumors) but an increase in hepatic adenomas (benign liver tumors), suggesting protective effects of hydroquinone. Levitt further reports that murine renal (kidney) tumors caused by use of hydroquinone do not appear relevant to humans after decades of widespread use, and murine leukemia has not been reproducible and would not be expected from small topical doses in humans as well. As such, it seems that topically applied treatments with hydroquinone are safe, as Dr. David J. Goldberg, a clinical professor of dermatology at the Mount Sinai School of Medicine reports, “Over 100 scientific articles confirm it is a safe topical for humans; no independent studies prove the opposite.â€
As an HQ user (love the stuff; get great results from it) I wanted to ensure that I was not gaining the lighter skin that I DO want at the risk of developping cancer (which I definitely DO NOT want
). Many of you share my interest in this. So, I decided to dig up medical/scientific data on this & share it here. Please take the time to read the above carefully. I hope it clears away any worries. DO go check out the thread on HQ & safety for those compounding with the raw 100% HQ crystalline flakes.
