Dermatologist doubts safety of treatment
Although people give generally positive feedback about the procedure, skin experts are less convinced.
Sunday Young Post columnist and dermatologist Dr Leung Sze-kee accepts that the fish may help with diseases such as psoriasis, but says the relief is temporary.
'It may last a few months to a year - it's not a magic cure. Sometimes, in the process, bleeding may occur. In that case you need to worry about open wounds and the possibility of infection with hepatitis B and so on.'
Leung also says the 'quarantine period works more in the sense of starving the fish than clearing up any germs' or disease.
