All those UV issues are clear to anyone that makes them.
many parlors are having special notice (on walls, pamphlets etc) so that interested person can be informed.
Some of them are even sticking to certain, tested ink label, with given guarantee that will be visible, glowy..
Even estimated duration is there to look upon.
Im sure that those 'reputable' shops are having right procedure allways when they separate UV ink aplication from ordinary colors for weeks and special care afterwards. The procentage of those with failed tattoo were allways gathered from those who were impatient to follow long term procedure. let them have it then.
And whose gonna convice someone to step off from idea of doing this beautifull art huh?
