A Miami-Dade County woman has been charged with delivering medical procedures without the requisite license after a sting operation exposed her unlicensed Botox practice. Lina Gutierrez-Farfan, 48, was apprehended Tuesday after she arrived to perform Botox injections in the parking lot of a former shopping center, the Miami-Dade Police Department confirmed.

The investigation into Gutierrez-Farfan began when a previous client contacted police with complaints of a treatment that left a lingering lump on his forehead. The client, who previously thought Gutierrez-Farfan to be a licensed professional, paid between $150 to $200 per session, according to evidence provided and as detailed in a Local 10 News report.

Undercover detectives arranged to meet with Gutierrez-Farfan at the Mall of the Americas, whereupon she agreed to perform the procedure for $350. At the scene, detectives observed her unloading a cooler bag from her vehicle, a blue Hyundai Tucson. A search upon her detention revealed two vials of a substance suspected to be Botox, as well as a medical filler labeled Replengen with Lidocaine, and a black box containing a syringe and bandages, as per the police report.

Gutierrez-Farfan now faces two third-degree felony charges: practicing a health care profession without a license and possessing drugs with intent to quickly sell or deliver. The Florida Department of Health issued a certificate of non-licensure at the site of her arrest, an action that corroborates her unauthorized practice in the medical field. Gutierrez-Farfan was subsequently transported to the Turner Guilford Knight Correctional Center, WSVN reported.
