a fragrance free lotion is good for a tattoo when it's healing because fragrance has a small amount of alcohol products in it and can dry out a fresh tattoo a tiny bit,
but a scented lotion will have no affect on a healed tattoo,or ANY lotion.
and yes,a good 30 or 50 SPF sunblock is a good idea when in a lot of sun,
only time and the sun will fade a tattoo.
