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.
"We're seeing a lift, we're seeing firming of the skin, definition of the jaw line, reduction of some of the fat under the chin," Song said, describing the effects of ultherapy.
The treatment is a two-hour procedure under local anesthesia. It's performed using a wand, and works by damaging the tissue underneath the skin of the face. The face reacts by producing collagen, which plumps up wrinkles and fine lines.
"It's more like turning back the clock," Song said of the procedure, which costs about $3,500 for a full-face treatment.
Laurita said it has really made a difference. When compared with pictures from before the treatment, pictures of Laurita after ultherapy show that her smile lines seem to have diminished and her jaw line is more defined.
"And over, you know, three to six months, it's just gradually gets tighter and more toned. It works," Laurita said.
As a licensed cosmetologist, Laurita says people can't remain young-looking without a proper beauty regiment at home. She says exfoliating, toning and moisturizing are important, and says people shouldn't skip sun block.
"It's very important," she said. "People think, 'Oh, I just need it in the summertime when I'm going out to lay out.' … You need it year-round. When you step out of your house, you need a sunscreen."
