Ultherapy PRIME: How It Works, Who It Suits and Recovery

Micro-focused ultrasound (MFU) is delivered while the layers are checked on real-time ultrasound imaging, creating tiny thermal points in the dermis and the SMAS (fascia) layer. Treatment takes about 30–90 minutes depending on area and lines, downtime is minimal (temporary redness, swelling or tingling), and some change right after, with gradual improvement over about 2–3 months as collagen rebuilds.

What is Ultherapy PRIME?

Micro-focused ultrasound (MFU) is delivered while the layers are checked on real-time ultrasound imaging, creating tiny thermal points in the dermis and the SMAS (fascia) layer. Tissue contracts and new collagen forms during healing, so firmness improves gradually.

Frequently Asked Questions

How is Ultherapy PRIME different from the original Ultherapy?

Does Ultherapy hurt?

There can be sharp sensations near bone, managed with numbing cream and energy adjustment. Comfort varies a lot between people.

Will Ultherapy make my face thinner?
