Aesthetic advances slow the effects of aging

Mark Nestor, MD, PhD, explains advances in the use of fillers to delay the effects of aging.

The growing number of aging baby boomers has led to an increase in patients seeking cosmetic treatments from dermatologists to delay the effects of growing older. This has led to the development of new procedures, including the insertion of absorbable lifting sutures and injectable radio frequency treatments.

Both treatments as well as a review of facial rejuvenation goals and techniques were presented Saturday during the “New Emerging Therapies” session. Mark Nestor, MD, PhD, director of the Center for Cosmetic Enhancement, Center for Clinical and Cosmetic Research, Aventura, Florida, presented “Aesthetic Update.”

The foundation of treating patients who want to delay the effects of aging on their faces begins in the anatomy under the skin, which has led to the development of many new injectables and devices. The key concepts in these treatments, he said,  are the four Rs: relax, refill, resurface, and redrape.

Important areas of focus are the triangle around the mouth and chin, and the midface, which are increasingly the target for injected soft-tissue fillers. The future of fillers is tunable absorbable microspheres. The composition of microspheres allows an immediate filling effect followed by stimulation of the body’s own collagen, Dr. Nestor said.

Another advance is the use of absorbable lifting sutures, which use minimally invasive technology to achieve immediate lift and repositioning with long-term volumizing secondary to collagen stimulation, he said.

The sutures are absorbable, have no barbs, are bidirectional, and provide lift to sagging tissue. They can be inserted in the brow, midface, and neck in about 45 minutes using a local anesthesia.

A similar procedure is injectable radio frequency for skin tightening and smoothing. It can also be used for facial nerve ablation, sub-dermal skin sculpting, ablation of axillary sweat glands, and vaginal rejuvenation, Dr. Nestor said.
