-For years, collagen injections have been used to minimize laugh lines and other wrinkles on the face. So-called face fillers are the fifth most popular, non-invasive cosmetic surgery procedure in the country.

Now, there's a new filler promising to help turn back the hands of time. This one's called Sculptra. It represents an entirely new way of thinking about the aging face.

Peggy Fohey is about to have her third Sculptra treatment. Dermatologist Dr. Dee Anna Glaser first numbs the face below the cheekbones and around the mouth. 15 minutes later, she begins injecting 10 syringes containing something called polyactic acid, the same material used to make absorbable stitches. The Sculptra forms a lattice-work in the skin that allows the body to lay down new collagen and skin to help fill out the face.

"My face has been thin for a long time but I have medical issues too that I've had for a long time which I think has contributed to this," says Fohey.

It's an entirely different approach to looking younger. Instead of removing fat pads from the face or a face lift to tighten the skin, the goal here is to restore a subtle type of fullness seen in younger people.

"If you look at us as children or infants we have these round, pudgy faces and as we grow into adulthood some of the round fatness begins to wane and we have more angles and lines in our face," says Dr. Glaser.

It's done in a doctor's office. Each treatment costs between a thousand and two thousand dollars. And it can take several weeks and several treatments to see results.

Massage is used after the treatment to help evenly distribute the Sculptra. Dr. Glaser says it isn't isn't for everyone. But this gives doctors and patients another non-invasive tool to enhance appearance.
