It Ain't What You Do.
Not all products and services are glamourous. Marketing them well says a lot about the quality of the marketers involved. If you can make the unappealing, appealing then you're a good marketer.
Bodily functions and ailments aren't glamourous, but that doesn't mean the marketing has to fall into the trap of withdrawing into the dull or antiseptic.
Don't bore on about how you solve the problem, just demonstrate what hardship you're removing from their life. How you can set them free.
How do you make the unappealing appealing?
By focusing on the indirect effects. By using brief, clear copy and an elegant and witty image. By being bright (in every sense).
