"Zits" on the Face of Humanity

Xunjian has a colourful command of the English language … his recent use of the word “zit” lingers in my mind.

A zit on the face is harmless … eventually it pops … heals … and leaves no trace of it’s existence.

OTH … a flurry of zits we call “acne” … an undesirable condition that leaves permanent scars.

Is the face of humanity contracting ‘acne’?
