A model from New Brunswick, New Jersey, recently appeared in court to answer to charges that she performed cosmetic procedures without a license. Anivia Cruz-Dilworth, 28, pleaded not guilty a month after charges were brought against her after she treated at least six different patients, the New Jersey-based newspaper The Star-Ledger reports.

The allegations stem from the claims of six women, who said that they suffered severe infections and were hospitalized after Cruz-Dilworth injected them with buttocks enhancing material. One of the women even required multiple surgeries.

State prosecutors offered the defense team a plea bargain that would require Cruz-Dilworth to serve three years in prison. However, her attorney said that they would not accept the offer, citing her lack of a criminal record and the fact that the material she used was routinely used for other cosmetic operations.

The Physician’s Coalition for Injectable Safety recently issued a warning against individuals posing as qualified injectors and condemns the practice as being dangerous. Qualified injectors should be members of the core societies and board-certified in their fields on practice. They should have experience and training with injecting, perform the injections in an accredited facility and be able to explain the risks and complications involved.
