Permanent makeup tattoo lasted about 6 years on my eyeliner. After having the eyeliner for about 4 years I went in to have my lips done. It didn't even last a year on my lips, and I could hardly see much difference from the beginning. My eyeliner is mostly gone now at six years. I went to the same person both times so there shouldn't be any difference because of that.
I will do it again for eyeliner but not for lips.
