We've come a long way... or have we?

"We made the dirt just radio-active enough to register on a Geiger counter."

At some point in history is was appropriate to prove how good cold creme was at removing dirt but making the dirt on some poor girl's face radio-active and then proving that she now has a radio-active face. You will note that in the advertisement, we never see her not having a radio-active face so we honestly don't know if she used her cold creme and was no longer radio active or if she mutated into a super villain worthy of her very own comic book.
