What is Hydroquinone? Most people here would be terrified if someone mentioned it. Is it really bad? If it’s bad why Doctor would prescribe it? Some people don’t want to use Hydroquinone because its bad etc, but they open they arm to steroid. I wonder if they knew the side effects? Once the side effects kicks in, there’s no turning back…
If you don’t have any skin disorders, DON’T USE Topical Steroid.
Back to Hydroquinone, this is summary from what I have read from Futurederm:
1.Use Hydroquinone in 4 months cycle, than alternate to milder substance such as kojic acid, arbutin and azelaic acid
2. Do not use product that contain benzoyl peroxide and resorcinol when using Hydroquinone
3. Do not let itnear your eyes
4. Some erroneously believe that hydroquinone may cause cancer. This rumor arose from a study that demonstrated mice exposed to hydroquinone developed liver tumors. However, these results were reported in a misleading fashion, as dermatological experts explained in a 2006 review in the Journal of the American Academy of Dermatology:
Instead of being harmful to the skin, hydroquinone increased the number of benign (non-cancerous) liver tumors, reducing the proportion of cancerous liver tumors in mice, thus suggesting that hydroquinone may exhibit protective effects. (For you science buffs out there, there was an increase in hepatic adenomas and a decrease in hepatocellular carcinomas).
As for other studies associating mouse kidney tumors with hydroquinone use, it has been argued that these are not relevant to humans. As Dr. David J. Goldberg, a clinical professor of dermatology at the Mount Sinai School of Medicine states, “Over 100 scientific articles confirm hydroquinone is a safe topical for humans; no independent studies prove the opposite.”
And this is from skinwhiteningforeversecret.com:
According to Web MD, which is widely considered to be a very reputable site, it says that this compound has been on medical watch lists as a possible cause of cancer for many years.
There have been studies involving rats where they have been fed a great deal of hydroquinone and went on to develop cancer. For that reason, some people want this ingredient in products banned forever and in some countries it is where the decision has already been made to take this compound out of products.
However, there is also a group of people that say it shouldn’t be banned for several reasons. For one, this group made the point that hydroquinone isn’t ingested by humans the way it was fed to rats so it is not correct to draw a comparison from those results.
They claim there is no direct link between putting the product on their skin and that resulting in them developing cancer. Note that this is not the only test that has been done to determine if there is a link to cancer.
One problem with that argument though is that the chemical is still absorbed into your blood stream through your skin, so though you may not be eating it, it is still going into your body. But like with many situations, if the adverse effect is not immediate it is very hard to conclusively say that there is a direct link.
Often is the case with carcinogens is that it can take years for the problems to show up, and once they do it can be too late to do anything about it. Whether or not you can prove this ingredient has been linked to cancer or not, is it worth the risk?
Hydroquinone is not banned, you can get 2% Hydroquinone over the counter, and you need doctor prescription for 4% and more. Dose is important, too much is not always good.
