Skin Tightening uses focused ultrasound energy to stimulate deep collagen production, gradually firming and smoothing the skin's surface. Unlike Radiofrequency Body Tightening, which heats the skin's surface layers, this treatment targets deeper tissue for patients with mild to moderate laxity on the arms, abdomen, and thighs. No downtime is required, and results build gradually over 2-3 months as new collagen forms. A series of sessions is recommended for optimal, lasting results.
