Yes swimming in the salt water would be ok..but you do need to take some triple antibiotic ointment and a bandage for when you get out you need to cover it from the sun and the ointment would help moisten it back up so colors stay bright, but please note that sun to any tattoo is bad it will make it fade..have fun! And enjoy your new tattoo
You shouldn't until it is fully healed and not scabbing or peeling.
Yes its safe the brine in the water is good 4 your tat its safe unless the tat is a picture of a SUFER!!
