This is a trip down memory lane, but was anyone ever subjected to Ivory Soap, probably as a kid - though they have had some marketing campaigns promoting it for women, too.
99.4% pure red scaly blotches on skin. Or was it just me who was this unfortunate? I still don't know what they put in it, but short of pumice soap it's the most brutal 'soap' (maybe I should say 'industrial cleanser'?) out there.
