Regular tattoo vs semi-permanent make up for scars?

[imtakinemout]

I have two year old white scars on the edges of the areola .. I've tried all creams and ointments known to man. The scars are pretty thin but visible.  I thought of getting a brown colored tattoo to camouflage them. But I'm not sure if I should get a regular tattoo or the so called semi permanent make up which I read doesn't last long. 

What do you think? Has anybody had a tattoo over scars?

Anybody?
