Ultrasound devices have two principle indications in today’s cosmetic practice: noninvasive skin tightening and noninvasive fat reduction, according to Murad Alam, M.D., M.B.A., a Chicago-based dermatologist and vice president, American Society for Dermatologic Surgery (ASDS).
“Ultrasound energy, which can be used to visualize babies and for other types of imaging, is unusual in that it can penetrate quite deeply into living tissues without causing harm,” Dr. Alam says. “One of the other benefits is you can do treatments with ultrasound in a way that protects the overlying skin and soft tissue. Depending on the type of probe you use, you can decide exactly where in the skin, the subcutis or even deeper, you want to deliver energy.”
Another great thing about ultrasound, he says, is that it’s color blind. Like nonvisible light technologies and radiofrequency, ultrasound is a skin tightening and fat reduction option in darker skin patients, without the worry of dyschromia or hyperpigmentation.
