My view on permanant make-up

So I saw this advert outside a beauty clique when I was in Germany; I'm not sure if this has hit in the United Kingdom, but I thought I'd write my views.

My first thought was 'Why would you want permanant make-up?' you wouldn't be able to change the colour of your eye shadow, to go with your outfit; the same goes for bush and lipstick.

But on the other hand you wouldn't have to time putting it on, also it wouldn't smudge. Aswell as the fact you wouldn't have to worry about spending money on new make-up.

Over-all though I wouldn't get this done myself, what are your views?
