After more than 50 years of no gloves, I had to begin using them when I started teaching at the college in order to set a good example. I use disposable Nitrile on one hand, and keep the other hand dry.
A good many years ago a dermatologist who who was an amateur photographer told me the dangerous one for dermatitis was the developer. This is because of the metol which causes dermatitis in some people.His solution was to process his hands like a piece of film or paper since the nature of our chemistry is to neutralize the previous chemical.
AS for pyro being more dangerous that is true, but hudroquinone is just as bad. Pyrogallol (pyrogallic acid) is the more dangerous. Pyrocatechol (pyrocat) is less harmful than hydroquinone. It is interesting to note that Pyrogallol and coffee are extremely close cousins on the benzene ring. That is why "caffeenol" works. By the way brewed coffee which has been allowed to sit on a warmer for a few hours does a very nice job without the addition of any other chemicals.
