Interesting. Hydroquinone developers have long been used in staining nerve tissue. Google Bodian technique. Here's an example

I knew HQ is used in skin lightening but in the "I wish I didn't know this" category, I learned it is also used in something called anal bleaching. Apologies in advance.https://anusbleaching.wordpress.com/tag/hydroquinone/
OMG, I think I've found my calling! I always thought about a career as a gynecologist, but could never take that much schooling or money to do it. But anal bleach specialist sounds like a possibility? Of course the sign above my door would say "Ladies only". To be honest I don't think I want to use HQ on any part of my body. Especially there! My wife says I wouldn't need it anyway 'cause I'm already a perfect one. John W
