Fake tans seem to be killing off our need for harmful sunbeds but there is another health threat to those wanting to be a bronzed beauty, a new injectable tan, Melanotan.

The Medicines and Healthcare products Regulatory Agency (MHRA) have issued a notice over this unlicensed product which is being advertised and sold illegally on the internet and even in some tanning salons and body building gyms.

The tanning product is designed to increase the body's levels of melanin which is a natural substance in the body which gives the skin its colour and is also produced to offer protection against the sun.

The MHRA explained that melanotan has not being tested for safety, quality or effectiveness. The Agency also warned of serious safety issues when it comes to using needles to inject the substance.

David Carter, head of the MHRA's medicines borderline section, said the agency had been in touch with 18 different companies so far about advertising Melanotan. "We are warning people not to use this product," he added.

"Don't be fooled into thinking that Melanotan offers a shortcut to a safer and more even tan. The safety of these products is unknown and they are unlicensed in the UK. The side effects could be extremely serious.

"If you have used either of these products do not use them again and if you have any concerns you should seek advice from your doctor."

Injections are bad enough when they're necessary but using a needle out of choice seems crazy to us. We'll be hitting the bottle instead, pass the St Tropez!
