ABC News' Juju Chang and Cathy Becker report:

Jacqueline Laurita lives a life in the spotlight.

As a star of the hit reality-TV show " The Real Housewives of New Jersey," the mother of three has been engaged in an on-air fight with former friend Teresa Guidice, a fight that most recently played out on the show's three-part reunion.

"It would just take a lot at this point," Laurita, 42, told "Good Morning America" of a possible reconciliation with her co-star and one-time friend. "It's hard. It's stressful."

Another thing Laurita can't reconcile is the concept of aging gracefully.

"I think that when people age gracefully, the people that age gracefully, it's because they can. Just for me, if I can fight it, I will," she said.

To deal, in part, with the reality of appearing on reality TV, Laurita admitted that she has tried many beauty approaches and treatments, including Botox, fillers and Fraxel laser.

The newest weapon in Laurita's fight is called "Ultherapy," a noninvasive skin treatment that uses ultrasound to lift, tone and tighten loose skin.

Dr. William Song, an aesthetic medicine specialist at Omni Aesthetics in Oakland, N.J., performs the procedure for Laurita. He told "GMA" that the procedure was one of his favorite anti-aging therapies. And there's zero downtime.
