Customers seeking botox injections should first see a doctor before undergoing the procedure, the Hong Kong Medical Association (HKMA) warns.
It said such procedures should be administered in Hong Kong for any emergencies and for purposes of insurance, the Hong Kong Economic Journal reports.
Botox (botulinum toxin) injections are increasingly used in cosmetic treatments to smooth facial lines, improve face muscles and eliminate body odor.
An average of two to three Hong Kong people each month seek emergency remedies after undergoing the procedure in mainland China, the report said, citing dermatologist Kingsley Chan.
Headline Daily reports that cases are up 20-30 percent from a year earlier.
Dr. Chan cited a female patient in her forties who could not open her right eye for one month after the injection.
There were other side effects such as skin rashes, he said.
Chan warned people not to take injections in different parts of their body and to spread these evenly.
HKMA said these treatments are best administered in Hong Kong by qualified medical professionals, adding price should not be the only consideration.
Mainland clinics offer botox injections for as low as 300 yuan (US$45.30).
Plastic surgeon Francis Ho said these treatments might be using fake botox, saying the normal cost of an injection is about HK$2,000 to HK$3,000.
HKMA vice president Chow Pak-chin said botox is a controlled drug and must be prescribed by a qualified doctor.
Chow called for legislation to regulate high-risk medical procedures.
