Shops offering tattoos and piercings pose an infection risk, and laws on who works in them should be tightened, say public health experts.
At present, anyone in the UK can set up a parlour and offer procedures without proper training, a report from the Royal Society for Public Health says.
But with one in five adults now having a tattoo, more should be done, it says, to protect the public.
NHS England said higher standards were “long overdue”.
“It shouldn’t be left to pick up the pieces from dodgy tattoo parlours who don’t take infection control seriously,” its medical director Prof Stephen Powis said.
The Royal Society’s report looks at so-called special procedures – tattooing, cosmetic piercing, acupuncture and electrolysis – which have all grown in popularity in recent years.
