TANNING salons are being urged: "Don't tan teens."
It is feared Government guidelines are being broken in Huddersfield because there is no legal age for tanning.
At present, it is up to the salon staff to decide who can use a sunbed. But pressure groups are calling for an age limit of 16.
The Government only suggest that people under 16 should not use the beds. But experts believe increasing use of sunbeds to achieve a year-long tan has pushed cases of skin cancer to epidemic levels across the UK.
The Kirklees Council Cabinet member for health and social care, Clr Dennis Hullock, said he was concerned and would be looking into the problem.
He added: "There is a big issue that needs addressing. I am sure the majority of private salons use common sense, but there should be some more concrete rules about who can and cannot use sunbeds.
"I will be looking into the problem and investigating whether we can push for some type of legislation. While there is a trend for tanning, youngsters are going to want to do it. But they need to be protected."
Nicola Ryan, of Macmillan Cancer Relief, called for the Government to properly legislate against young people using sunbeds.
She said: "We would support any move to stop under-16s being able to use sunbeds at salons.
"It is in the teenage years and the 20s when people are most likely to do the damage that will lead to skin cancer developing when they get older.
"Young people have a belief that it will never happen to them and disregard the dangers of using sunbeds.
"They want to look good, but they should know what that might cost in the long run - and it can speed up ageing."
Kirklees Active Leisure already has strict rules in place to make sure youngsters do not use the beds at sports centres in Huddersfield, Dewsbury, Colne Valley and Scissett.
Each user must be registered and children cannot even be in the same room while an adult is tanning.
Ian Whitehead, KAL business development manager, said: "We review our sunbed policy each year, taking into account the latest research. In the meantime we follow strict guidelines and best practice procedures."
Helen Turner, assistant manager of Kwik Tan, in New Street, Huddersfield, said the rules were already very strict at the salon.
"Everyone has to fill out a form when they join and they are asked questions about their health," she said. "We do not let anyone under 18 on the sunbeds and if we think they are too young we ask for identification.
"We have turned people away."
