"Facial pus explosion" opens a lot more doors than "acne."
And speaking of treatment, have you ever noticed how pharmaceutical companies regularly throw ridiculous wads of cash at a consultant to come up with names for their pills, yet new drug names all end up sounding the same? It's as if said highfalutin consultant laced his dog's food with Scrabble tiles (with an extra dash of Xs and Zs) and jotted down whatever Rover shat out. Prozac, Lexapro, Paxil, Zoloft, Luvox ...
That's because, for a bunch of wacky historical reasons, the letters X and Z have become associated with technology and innovation -- stick one or both of them in a drug name, and you have something that just screams "SCIENCE!" On the other hand, the magic of sounds can also make your drug appear gentle and non-threatening. For example, Prozac -- all efficient-sounding and full of plosives (consonant sounds like k and p that produce a short burst of sound, like little mouth-explosions) -- was also marketed as the premenstrual aid Sarafem, which manages to bring to mind a common female name, "femme," and angels, all at once. This is why that consultant we mentioned can afford the expensive brand of dog food, people.
