The feds accuse a Stoughton woman of injecting many people, across well over 2,000 appointments, with fake Botox and knock-off dermal fillers.

Rebecca Fadanelli, 38, who also goes by the last names “Daley,” “Dailey” and “Hawthorne” according to the complaint, was arrested the day after Halloween for her alleged activities and appeared in federal court in Worcester the same day. Magistrate Judge David H. Hennessy released her under standard conditions on $10,000 unsecured bond.

Acting U.S. Attorney Joshua Levy said that Fadanelli’s deception of her hundreds of clients “is illegal, reckless and potentially life threatening.”

The feds say Fadenelli administered knock-off Botox, Sculptra and Juvederm from China and Brazil at her business called Skin Beaute Med Spa, with locations in both Randolph and South Easton. From March 2021 to March 2024 she allegedly performed at least 1,631 Botox appointments and 1,085 filler appointments.

Fadanelli advertised her services on her website with a false story replete with an erroneous claim that she had a degree in anatomy from “Havard” (sic). According to the feds, she’s actually a registered aesthetician — a person who provides non-medical skin treatment — without the proper licensure to administer any prescription drug, let alone fakes that could contain any measure of dangerous ingredients.

While the feds say Fadenelli amassed more than $900,000 in her enterprise between March 2021 and March 2024, her downfall quietly began early on when one of her clients complained to the U.S. Food and Drug Administration that the Fadanelli’s filler injections in September 2022 left her with “bumps” and “tingling” sensations.

FDA Special Agent Brian Hendricks quickly found that his agency wasn’t the first federal bureau onto Fadanelli. According to his affidavit, a U.S. Customs and Border Protection and Homeland Security Investigations representative told him that an officer had already opened an investigation into her and they had already seized packages addressed to her.

The CBP in October 2023 seized “a variety of prescription drugs and devices” from Fadanelli at Logan Airport after she returned from a trip to Brazil, and then over the next five months seized at least six packages addressed to Fadanelli or her employees and sent to either her home or the spa locations, according to Hendricks.

Fadanelli’s charge of importing merchandise contrary to law could put her in prison for as long as 20 years, and her charges of knowingly selling or dispensing a counterfeit drug or counterfeit device could each ring up an additional decade behind bars.

The feds say anyone who worked with Fadanelli can find more information and can fill out a questionnaire at Justice.gov/usao-ma/victim-and-witness-assistance-program/united-states-v-rebecca-fadanelli/.
