A disturbing array of products and devices have been uncovered after authorities raided seven cosmetic clinics across Sydney.

NSW Health authorities say the haul includes antibiotics, botulinum toxin injections, hyaluronic acid dermal filler injections, very high-strength lidocaine local anaesthetic creams, antiseptic lotions, vitamin injections and antiviral tablets used to treat herpes.

Ampoules of human placenta injections were also found.

None of the seized products and equipment are listed on the Australian Register of Therapeutic Goods, with most having been illegally imported from China and South Korea.

The clinics were reportedly employing a number of unlicensed nurses too.

“We're also investigating the medical practitioners associated with the clinics to determine if the medical practitioners were exercising professional oversight as these products, such as Botox and dermal fillers, are actually prescription medication,” NSW chief health officer Dr Kerry Chant said.

No arrests have been made.

Health Minister Brad Hazzard urged anyone looking at cosmetic treatment or surgery must make sure their practitioner is licensed.

“Giving your body over to somebody who may be using an illegal product — you may not even know what's in the product — possibly being administered by a person who has no medical training whatsoever is really a dangerous exercise,” he said.

“I think some people think Botox is like having a cup of tea, well it's not.

“It actually can be potentially dangerous.”

Mr Hazzard said the issue crosses state lines, and called on Federal Health Minister Greg Hunt to create a national strategy.

“I asked him whether he would effectively review what's going on federally,” Mr Hazzard said.
