SAN DIEGO -- Believe it or not, a person's lips can give away their age. That is why so many people are looking for ways to plump up their lips.

Now, a new technique is achieving great results without any injections, 10News reported.

Salon owner Lisa Xavier, a former model, took action after years of plastic surgery left her with hard "square-looking" lips.

"As vain as that may seem, it's just something I wanted to change," Xavier said.

According to plastic surgeon Dr. Randal Haworth, as a person ages, their body "drops."

"Just like the rest of the face, breasts and other parts of the body, the lower lip drops. It's no exception. So, we start to see the lower teeth at rest," Haworth said.

Now, a new procedure brings the lip back up to a youthful position. Instead of injecting foreign substances like collagen, Haworth simply tightens the muscles inside the lip.

"What I did with Lisa, is to do an internal tissue rearrangement -- by moving the inside skin of the lip upwards and outwards, and also in the process, tightening the muscle from here to here between my thumb and index finger," Haworth explained.

The procedure can be done with local anesthesia and takes only a few minutes.

The process left Xavier with lips she loves -- lips free of foreign substances.

"They're really full, which is really nice. I don't have something in my lip, which is great. I don't have to worry when I'm 90 years old that this thing in my lip is going to cause some kind of problem," Xavier said.

The lower lip lift costs about $1,500.

Haworth believes he is the only plastic surgeon performing the procedure.
