Some skin tightening treatments use focused ultrasound energy, which heats skin at specific depths (up to 5mm deep) and locations to induce collagen production and help skin become firmer. Treatments are delivered via a handheld device, which transmits the ultrasound waves through the skin’s surface. Ultrasound technology has been used in medicine for many decades, and ultrasound skin tightening has an excellent safety profile. It is effective for older patients looking for a mini facelift without surgery and for younger patients who want to maintain their skin profile and prevent skin laxity as they age.
