So far, so good! I've been dunking my hands in HC110 and TMax RS for 6 years without allergic reactions or rashes. My understanding is that while hydroquinone is sensitizing, and can cause serious health consequences to some people, pyrogallol is toxic, and enough exposure causes health consequences to all people. The warning on the HC110 bottle (and any package containing hydroquinone) warns of possible skin reaction. On the other hand everyone who writes about PMK notes that pyrogallic acid is "nasty stuff" and warns about the powder, as well as direct contact with the developer solution.
That said, all the neat stuff in our darkrooms is potentially lethal, if not to us, then to our environment, and should be handled in a responsible manner. We really can't be too careful.
..but I'd hate to go back to gloves! ;-(
