Treatment comparison
XERF vs Thermage
XERF and Thermage both use radiofrequency, but the treatments feel different. Thermage uses a deeper single-pass approach, while XERF builds heat gradually over several passes. We prefer XERF for clients who value comfort, minimal recovery and a refreshed look soon after the appointment.

Our approach
XERF
The even, comfortable heat
XERF is the monopolar radiofrequency treatment offered at all three Joanna Vargas spas. Its handpiece moves slowly across the skin, keeping heat at a comfortable, uniform level so the full session stays relaxing while collagen remodels.
Fine lines, texture, early laxity and a same-day glow.
Monopolar radiofrequency warms the upper dermis evenly, pass after comfortable pass.
None. Mild flushing fades within about 30 minutes.
A short series builds the best result, then seasonal maintenance keeps it.
Thermage
The single deep pass
Thermage covers the treatment area with one deeper broadband radiofrequency pass. The heat peaks are stronger, sessions are shorter, and it is often selected for larger or looser areas beyond the face.
Moderate laxity on the face and body in a single appointment.
Broadband radiofrequency heats deeper tissue in one sweeping pass.
None to minimal, though the deeper heat can feel intense during treatment.
Usually one treatment, with tightening appearing over two to six months.

The difference
Why XERF is the better choice
These treatments use the same general technology in different ways. XERF applies heat gradually, which makes it our preferred option for a more comfortable appointment.
- Heat delivery: XERF builds warmth through repeated passes. Thermage uses stronger heat at greater depth in a shorter sequence.
- Timing: XERF can give the skin a refreshed appearance soon after treatment, while collagen remodeling continues over time.
- Recovery: Mild flushing after XERF usually fades quickly, and normal activities can resume right away.
- Suitability: We assess your skin and goals before recommending XERF or another treatment.
