The thing is, my facial skin is not very sensitive. It can take a lot of abuse, from soaps, dull blades, alcohol splashes, etc.
It's just the Pear's that affects it so.
I never use a pre-shave anyway, and the Pear's was just a science experiment.
Then I wonder if you got a bad batch of the Pears soap! Such as residual lye. You might see if they have a customer service contact and let them know about your issue!
