XERF suits people with mild to moderate skin laxity who want a firmer jawline without surgery or downtime. Results generally last from several months up to one year. This guide covers the benefits, the limits and what to know before you decide.
How long XERF lasts
Your skin keeps building new collagen for several months after treatment. Results generally last from several months up to one year, depending on your skin care and lifestyle. Our aftercare advice is to wear sunscreen regularly, avoid strong heat and strenuous exercise for 1–2 days, and avoid exfoliation for 3–5 days.
How many sessions you need
Most patients notice firmer skin after the first session. Your doctor will advise how many sessions suit you.
When you see results
Most patients notice firmer skin after the first session. Collagen keeps building for several months afterwards, so results develop gradually.
How long a session takes
A session takes about 30–60 minutes depending on the area. No numbing cream is needed and you can return to normal activities straight away.
What XERF does
XERF is a skin tightening device that uses dual-frequency monopolar radiofrequency (6.78 MHz and 2 MHz), developed by Cynosure Lutronic. It delivers heat at three depth levels to stimulate collagen and elastin. It can be used on the face, jawline, under the chin, neck and body.
Benefits
- Several depths in one session. Your doctor can adjust three depth levels for each area.
- No numbing cream. ICD cooling protects the upper skin layer. Most patients feel a gentle warmth during treatment.
- No downtime. You can return to daily activities, skincare and makeup straight away.
- Energy matched to your skin. Wave Fit Pulse measures skin impedance in real time and adjusts the output automatically.
- Lower risk of skin burns. Technology designed for well-controlled treatment: ICD Cooling cools the skin during treatment, while Wave Fit Pulse Technology controls how the energy is delivered. Together they help reduce heat build-up on the skin and make the procedure more comfortable.
Limits to know first
- It suits mild to moderate laxity. For more advanced laxity, your doctor will assess you and may suggest another option. Results depend on the individual, so consult a doctor first.
- Results build gradually. New collagen keeps forming for several months after treatment.
- Results are not permanent. They generally last from several months up to one year.
