Treatment comparison
Ultherapy uses focused ultrasound at set depths to target sagging, especially in the cheeks and under the chin. Thermage FLX uses radiofrequency to heat the dermis, which suits fine lines and general skin laxity. Sagging tissue tends to favour Ultherapy, loose or crepey skin tends to favour Thermage, and some patients combine both.
