The US Food and Drug Administration has given the green light to two devices designed for the noninvasive tightening of the skin, One utilises radiofrequency technology while the other relies on ultrasound technology. Both devices produce heat, although by different methods. The heat produced by the devices elicits a micro-inflammatory stimulation of fibroblasts, which stimulates the production of new collagen in the deep layers of the skin, thus causing a compensatory tightening that can last a year or more.

The devices, which are known as Thermage and Ulthera, are used to tighten mild to moderate skin looseness.

And thanks to ongoing refinements with radiofrequency and ultrasound-based contouring modalities, these devices have become more versatile and patient-friendly since they were first introduced.

In the ultrasound category, Ulthera is the only device that can deliver energy below the surface of the skin to a depth of 4.5 millimeters, targeting the foundational superficial musculoaponeurotic system (SMAS) layer, which is what plastic surgeons tighten in a traditional facelift.

At that depth, some patients reported feeling discomfort. To ensure the most comfortable patient experience, a recent updated software system now affords a more comfortable procedure.

Treatment with high density demonstrates a safe and effective result with a high rate of patient comfort and satisfaction.

The radiofrequency skin tightening procedure Thermage is monopolar.

The advantage of monopolar radiofrequency is that it provides bulk heating so it penetrates deeper than bipolar radiofrequency, and is able to reach the deep skin layer and impact a larger area.

The latest advances in the monopolar radiofrequency device include the addition of comfort pulse technology to the facial-treatment tip, which is designed to send energy deeper and also makes it more effective.

Both radiofrequency and ultrasound devices have been used successfully in properly trained and skilled practitioners’ hands.

Those who are thinking about a skin-tightening procedure should absorb the above information and choose a skilled physician who is able to put his or her experience to use in truly improving the contour of the patient’s face, with long-lasting results.
