Dear @jonnychgo why don't you try some temporary method?
And after having your tattoo for some time, you decide if you want to make it permanent or not.
The video below provides different perspectives of Temporary vs. Permanent, without talking about age.
However, tattoos look good thanks to the muscle, fat, and collagen that one loses at an older age.
Whenever I've considered having one done, I asked myself: Will this look good on me when my skin looks like wrinkled paper?
My answer so far has always been: No.
