The true story behind this expression is yawn-worthy. Mind your own beeswax probably dates to the 1930s with the dull explanation that beeswax is just a playful replacement for business. But, you’re dying for some grist from the rumor mill, aren’t you?
Let’s go back to the 1700s—and automatically the added centuries make the story more interesting. Before inoculations against it, the small pox was one of the many deadly diseases people had to contend with. Those who survived were usually badly marked by pox scars (hence the term pockmarked).
Legend has it, pockmarked women spread beeswax over their skin to smooth its appearance. This is where the story diverges. In one version, a woman who got uncomfortably close to a fellow beeswax babe would be told to “mind her own beeswax.” As in, “quit staring at mine and for God’s sake, move back.”
The other version is even funnier. A woman who sat too close to the fire would be reminded by a sympathetic companion to “mind her own beeswax” and tend to her melting face.
