The word acne was actually created as a mistake. Acme, meaning the highest point of development, was copied incorrectly as acne
way back in the time of having to hand-copy manuscripts. This gave birth to the word acne and since it was first read in the context of what should have been the context for acme, it was interpreted and defined as high points
. This was later taken to mean high points of inflammation which gave way to its use as a medical term for high points of inflammation on a person's face.
