'Mind Your Own Beewax'

This came from the days when smallpox was a regular disfigurement. Fine ladies would fill in the pocks with beeswax. However when the weather was very warm the wax might melt. But it was not the thing to do for one lady to tell another that her makeup needed attention. Hence the sharp rebuke to "mind your own beewax"

Interesting, isn't it?
