Jennifer Matthews: Salon owner Lisa Xavier is a former model, so when years of plastic surgery left her with hard square-looking lips, she took action.

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

Dr. Randal Haworth: What happens is that everything drops. Just like the rest of the face and the 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.

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

Dr. Randal Haworth: So 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.

Jennifer Matthews: The procedure can be done with local anesthesia and takes only a few minutes. It left Lisa with lips she loves that are free of foreign substances.

Lisa Xavier: 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.
