Here’s a vintage Fleishmann’s Yeast ad (found here), which presents yeast as the answer to the horrors of pimples–awful, hideous pimples!

I don’t know in what world high schools have movies, but whatever. Clearly, the message is “pimples = social death and eternal loneliness.” It’s not just that Davy can’t be in the movie due to his horrible affliction; if he can’t play the lead along with his girlfriend, he faces the possibility of losing her to a leading man with a clear complexion.

Given such messages about the importance of clear skin, it’s no wonder teens and their families were willing to shell out enormous sums of money on skin-care products. Apparently yeast didn’t catch on as a treatment, though.
