For Patterson, adding cosmetic services to enhance beauty seemed like a no-brainer.

“If you think about it, we study the face, the muscles, the nerves, we use needles all the time,” said Patterson, 30. “It actually makes a lot of sense for a dentist, especially if you have an eye for cosmetic symmetry.”

To enhance the smile, for example, she administers fillers in nasolabial folds, in lips and for the lines above the lips.

And she injects Botox to relax the upper lip for those who have gummy smiles — as an alternative to surgery.

“Botox and fillers have allowed dentists to do amazing things,” Patterson said. “It really makes a difference for the client.”

For the doctor, too. Spa services now represent about 15 percent of her revenue.

“It creates another stream of cash coming into the business,” she said. “And women will tell their friends they got Botox today, versus they got a cleaning today.”

Dr. Alejandro Espaillat, an ophthalmologist, still performs eye surgery in his Brickell Key office, but he is aiming his practice on wellness, including aesthetic procedures.

“I believe ophthalmologists are uniquely trained to treat any area of the eyes and face, because of our knowledge of facial anatomy and movement,” he said.

So when his patients receive refractive surgery, they can also now get Botox, fillers, laser treatments and more.

“They realize that now that they can see better, they not only want to see better, but they want to look better,” said Espaillat, 47, medical director of the Espaillat Eye and Laser Institute.

About half of his practice’s revenue comes from aesthetics, and half from ophthalmology, he said.

Aesthetic procedures include laser hair removal, resurfacing of the skin, skin tightening and cellulite treatments, as well as facials, said Gabriela Oviedo, aesthetics director of the Brickell Key Medical Center, which is a division of the Espaillat Eye and Laser Institute.

Just last week, the center added a new weight-loss program, and more expansion is in the plans.

“Having a comprehensive approach to the wellness of the person is important,” Espaillat said, “from the psychological aspects to the physical aspects.”
