I have zero regrets for any of my tattoos, not even the one I laser we off. What mine represent to me were apart of my life for a long time before getting the tattoos though. I know tattoo regret is very popular but have a feeling many here on the boards won't have any comic related tattoo regrets other than possibly choosing the wrong artist who may have lacked the skill for the task. I've yet to see any of those posted though.
Nowadays tattoo removal is growing more and more popular for many reasons. A bad tattoo to begin with, an ex's name, tattoo location, or the fun one of fading the ink to get something new. I've come across a few artists who decided to get laser treatment with the main purpose of getting new tattoos. One even stated he'd probably laser the new ones off in a few years to get more new ink. Just like a painting on the wall. Well, sort of. I'd rather smash my finger with a hammer hanging a picture over exstensive laser treatment any day.
