Thermage FLX
Thermage FLX uses radiofrequency heat energy to smooth and firm the skin's surface and dermis, and is one of the strongest non-surgical skin-tightening treatments available.
DetailsUltherapy Prime applies the latest HIFU (high-intensity focused ultrasound) technology to deliver the proven lifting effect of Ultherapy with even greater precision and safety. Like earlier Ultherapy devices, it focuses ultrasound energy to create a thermal response in the SMAS layer, but with an upgraded ultrasound display that allows fine-tuned energy control for different skin thicknesses and treatment areas.

Ultherapy Prime
Effects & advantages
Focused ultrasound lifts skin non-invasively from the inside out, restoring elasticity and improving sagging.
Starting around 3 months after treatment, the facial contour becomes more defined and the jawline looks firmer.
Collagen regeneration, elastic fiber renewal and dermal elasticity increase step by step, which tightens skin and smooths wrinkles.
90 days
Collagen takes about 2–3 months to rebuild, so full results typically show around 90 days after treatment.
Is it for you?
Ultherapy Prime offers three main benefits. First, it lifts skin non-invasively from the inside out, restoring elasticity and improving sagging. Second, starting around 3 months post-treatment, the facial contour becomes more defined and the jawline visibly firmer. Third, it generates stronger, healthier collagen and elastin, tightening skin and smoothing wrinkles. Since collagen regeneration takes about 2–3 months, full results are typically visible around 90 days after treatment.
How it helps
Sagging skin
Lifts and firms from inside, addressing both age-related collagen loss and a weakened SMAS layer.
The principle, in plain words
Ultherapy Prime focuses ultrasound energy deep under the skin, like a magnifying glass focusing sunlight. The tissue tightens and your skin slowly builds new collagen.
Like a magnifying glass focusing sunlight, Ultherapy Prime concentrates ultrasound energy deep into the SMAS layer without damaging the skin's surface, causing tissue to contract and tighten.
