Technological advancements for skin tightening have made it possible for a more natural alternative to surgical facelifts. Two of the most standout treatments at the forefront of skin tightening are XERF and Ultherapy Prime®. While both treatments aim to lift and tighten the skin, they utilize different technologies to achieve the desired results.
XERF
How it works
XERF uses dual-frequency radiofrequency (RF) energy to heat tissue at both superficial and deep layers. This multi-level approach stimulates collagen production while tightening existing fibers, resulting in smoother and firmer skin over time.
Best for
- Mild to moderate skin laxity
- Early jowling or signs of sagging around jawline, neck or cheeks
- Crepey or thinning skin
- Collagen stimulation and skin firming
- Patients wanting gradual, natural-looking improvement with no downtime
What it feels like
Most patients describe XERF as warm but not painful. Treatments are generally comfortable and require little to no downtime.
Results timeline
- Subtle tightening may be seen right away.
- Collagen continues building over the next 4-12 weeks.
- Typically performed as a series of treatments for optimal results, typically 2–4 sessions per year.
Why patients love XERF
- Comfortable sessions
- Safe for many skin types
- Improves tone, texture, and firmness
- Minimal downtime
- Great for maintenance and prevention

Ultherapy Prime®
How it works
Since the original Ultherapy®, this next-generation device targets the deeper layers of the skin with more efficiency and less pain. Ultherapy Prime® uses micro-focused ultrasound energy to target the deeper structural layers of the skin while bypassing the skin surface. It creates precise thermal points, stimulating collagen production and resulting in a firmer, more youthful appearance.
Best for
- Mild to moderate skin laxity
- Sagging in the lower face, neck, chin, and décollete
- Drooping brows
- Patients looking for a low maintenance, single-session lifting treatment
What it feels like
Ultherapy Prime® is described by patients as brief heat or tingling sensations. Comfort measures, such as numbing cream, can be used prior to treatment.
Results timeline
- Gradual lifting over 2–3 months
- Continued improvement up to 6 months
- Usually 1-2 treatments a year with yearly maintenance.
Why patients love Ultherapy Prime®
- Safe for all skin types
- Deeper tissue targeting
- FDA-cleared for face, brow, neck, décolleté, arms, and abdomen
- Long-lasting collagen stimulation

Which One Is Better?
It really depends on every individual’s skin and goals. Each device is unique and may work better for some patients rather than others.

HALO BEVERLY HILLS tip: Many patients achieve the best results by combining both, starting with Ultherapy Prime® for foundational lifting, followed by XERF for a touch up in skin quality and ongoing collagen support.
