ABC News' Cathy Becker reports:

For most mothers and daughters, bonding time comes in the form of a trip to the nail salon or a day of shopping at the mall.

For 65-year-old Lynda and her daughter, 38-year-old Stefanie, bonding time involves a more lasting, and life-changing, type of activity: cosmetic surgery.

The duo is no stranger to adventures - they've zip lined, snorkeled and helicoptered their way around the world from their home bases in Montreal, for Lynda, and Los Angeles, for Stefanie - so they figured they would continue their tradition by coming together for a nip and tuck.

"I thought this would be a nice thing for us to do together because we could be a support system," Stefanie, a pediatric speech language pathologist , told ABC News' Cecilia Vega. "We [could] have a good three or four days together to vegetate and relax."

Lynda saw the mother-daughter time together as an opportunity to get rid of what she described as a nagging sag on her neck.

For her daughter, it would be a time to fix her chest and slim down her waist.

"Something I have noticed as I have been getting older is that my bust is hanging lower," Trentholme said.

In late May, Lynda traveled to Stefanie's home in Los Angeles so that both mother and daughter could be under the care of Dr. Peter Fodor, a Los Angeles-based plastic surgeon who says the mother-daughter approach is great in his business.

"I love it," Fodor said. "The patients who start with a supportive relationship, they really help each other and I welcome that."

Fodor performed a neck tuck and inserted cheek fillers on Lynda, while her daughter got a breast lift and a tummy tuck.

Nearly seven weeks post-surgery, in July, both mother and daughter said they were happy with the results of their extreme bonding adventure.

"I definitely notice a difference obviously with my stomach," Stefanie said. "I am really thrilled about my bust."

"I feel really great about myself," echoed her mom. "I am able to wear chokers and things I never wanted to before that would address my neck."

"Now, bring it on," she said.
