Laughing Bear, I'm not sure what you were trying to say. Is there a typo in there? "how a person can react to a base and not have a reaction." I will try to answer what I think you might be trying to ask.
I would think this depends on the sensitivity of one's own skin. Ever since the Willow Fire I have had these out breaks. I have never had so-called "sensitive skin".
All I can do is report the facts in my case: I soak, I breakout. Or I soak, I rinse with an acidic, I don't break out (or at least, mildy in the places I somewhat missed).
What would you conclude from these facts?
