There are fears tattoo artists will have to increase their prices as Wales becomes the first part of the UK to introduce new rules for artists.
The Welsh government rules mean practitioners will have to meet stricter hygiene and safety standards in order to be given a licence, which they'll have to renew every three years.
It follows concerns from medics about the risk of serious infections.
"I imagine the prices of tattoos are going to go up to accommodate this," said Kim Thomas, a tattoo artist in Newport.
