Beauty clinics offering the treatment in Hong Kong promise that it will make people look more youthful, with whiter skin and smaller pores, and strengthen their immune system. But the procedure does not appear to have any proven cosmetic effect.
Police and health officials are jointly investigating how the blood was contaminated and the relationship between the beauty clinic, the blood treatment lab and the medical practitioner who carried out the procedure.
DR Beauty said in a statement on its website that the doctor who carried out the procedures was not employed by the clinic.
Police Commissioner Andy Tsang said officers are treating the death as a criminal case and may consider manslaughter charges, according to local broadcaster RTHK.
