A woman from China’s facial skin has been damaged after a veterinary hospital applied liquid nitrogen used to freeze cattle sperm to try to remove freckles from her face, a newspaper reported. The woman, 46, who lives in Shangluo in Shaanxi province, was persuaded to take the treatment by a primary school teacher who had trained at a beauty company, according to the Chinese Business View . The woman, whose full name was not given, said the treatment had shown no sign of removing her freckles four months after it was carried out and had damaged her skin. She has tried to get back the 10,000 yuan (HK$12,000) she paid for the treatment, but with no success, the report said. The teacher runs a freckle-removing business and had a contact at the veterinary hospital where the treatment was carried out.

Doctors at a local hospital said most freckles were removed with laser treatments and the use of liquid nitrogen was complex and needed more advanced technology.
