Olmedin, as a filler material, used to be used in large quantities for various cosmetic surgery procedures since 1997. The main component of Omedine is polyacrylamide hydrogel, the monomer of this compound may decompose in the human body and become highly toxic, poisoning the nervous system, damaging the kidneys, and causing irreversible damage to the circulatory system, and the World Health Organization has listed this substance as a suspected carcinogen. Patients who come to our hospital to have their breast implants removed have never stopped, and the most recent one was a patient who had her breast implants injected 2 years ago. However, as early as April 30, 2006, the state explicitly banned the use of Omadine in humans. One of them was diagnosed with cancer during surgery and had to have a mastectomy. If the injection site was not in a cavity in the first place, it would have been difficult to take it clean. It must be checked regularly. Please pay attention to all of you who want to beauty: if it is not your own or the organism can not absorb something absolutely do not inject beauty.
