The vanity plates on his two Mercedes read "SKN STAR" and "DR DB."
His advertisements quoted actor Kirstie Alley as saying, "Dr. David has discovered the science of great skin and I'm glad I've discovered him."
He gave himself the title "Dr." on his business cards for his International Health and Skin Care Institute of Tampa Bay, authorities said.
Then on Wednesday, 41-year-old David Anthony Beaudrie - not a doctor, officials say - was about to inject an undercover Pinellas County sheriff's deputy with what was supposed to be collagen before she identified herself and stopped him.
Once the detective identified herself as not a patient, he told her the $150 injection was filled with water, not collagen, authorities said.
The syringe was sent to a lab for testing, said sheriff's Sgt. Jim Bordner.
And Beaudrie of 12820 Killarney Court in Odessa went to the Pinellas County Jail, charged with one count each of practicing medicine without a license and fraud.
"We don't know what he injected in them," Bordner said of Beaudrie's patients.
Beaudrie told detectives he never met Alley or singer Gloria Estefan, who also was quoted in his advertisements as touting his work, officials said. Representatives for Alley and Estefan have not returned calls by the Sheriff's Office, Bordner said.
Beaudrie was arrested Thursday afternoon after a three-month investigation of his Safety Harbor business, International Health and Skin Care of Tampa Bay, at 2753 State Road 580 in Clearwater.
The business also operates from a Hillsborough County location at 1413 S Howard Ave., Suite 207 in Tampa, according to Pinellas officials.
Beaudrie was released from jail after posting $10,000 bail. On Friday, a man who answered a phone number listed on Beaudrie's advertisements hung up when a Times reporter identified herself. He didn't return calls seeking comment.
Detectives say Beaudrie advertised cosmetic treatments that included injections of Botox or collagen and cold-laser facelifts. He also advertised himself as Dr. David Beaudrie P.M.E., as well as being a "holistic dermatologist" and a "paramedical esthetician," officials said.
But officials said an investigation found Beaudrie has no medical degree and is licensed only by the Florida Board of Cosmetology as a facial specialist, which allows him to perform microdermabrasion and treatments for acne.
Beaudrie also claimed to have a background in biochemistry and have developed his own line of skin care products known as David Beaudrie Botanicals.
A single fluid ounce of "DB Wonder Serum" sold for $32. Six ounces of "Blue Tango Scrub" cost $25.
But Beaudrie told detectives that he ordered the products from a company that placed his label on them, officials said.
The Sheriff's Office and state Health Department have been working together on the investigation, which is ongoing. Investigators want to hear from people who have been treated by Beaudrie.
"We'll see where we go from here and see where the case leads us," Bordner said. "Obviously, a big part of that is getting people to come forward."
