NSW raids find dangerous beauty products

Doctors are warning the public of the dangers of illegally imported cosmetic products after a series of Sydney raids uncovered a number of potentially deadly substances.

NSW Health raided seven clinics in Chatswood and Haymarket on Tuesday and Wednesday, seizing a number of illegally imported products, a spokesman said in a statement to AAP.

Authorities are now investigating medical practitioners associated with four of the clinics in relation to their oversight of injections of Botox and dermal fillers.

"Anyone planning to have a cosmetic procedure at any cosmetic clinic should be highly cautious," the spokesperson wrote.

In the wake of the government raids, the Cosmetics Physicians College of Australasia (CPCA) on Friday issued a warning after uncovering numerous websites offering to sell prescription-only cosmetic injectable substances.

Those using the illegally imported drugs run the risk of both a poor aesthetic result and fatal consequences, the CPCA said in a statement.

"The general public should be aware that the substance they intend to purchase online may not be sterile, with the potential to lead to difficult-to-treat infections, or worse, may be a toxic blend of something unidentifiable, leading to longer-term illness, scarring and disfigurement," the organisation said.

The raids and warnings come just weeks after 35-year-old Jean Huang died after being administered with a local anaesthetic and breast fillers at a Sydney beauty clinic.
