DetailsXERF RF Lifting Treatment
XERF Lifting uses radiofrequency energy to reach deep layers of the skin, stimulating collagen production in a non-invasive lifting treatment. XERF restores elasticity and texture naturally while smoothing wrinkles. By promoting collagen production deep in the skin through radiofrequency heat, skin becomes progressively firmer and more elastic over time.

XERF
Effects & advantages
Key features of XERF
- 01
Firmer, lifted skin
Radiofrequency heat deep in the skin stimulates collagen production, so skin becomes progressively firmer and more elastic over time.
- 02
Less localized fat
Reduces localized fat in areas like sagging cheeks and the double chin, without surgery.
- 03
10 energy levels
Precise, personalized
10 adjustable energy levels allow precise, personalized treatment.
- 04
3 stage ICD cooling
Built-in safety
An EFFECTOR sensor monitors skin temperature, and 3-stage ICD cooling prevents excess heat buildup.

Results after XERF
XERF is effective at reducing localized fat in areas like sagging cheeks and the double chin, without surgery. Strong heat stimulation in the dermis helps clear unneeded fat and stimulate collagen regeneration, lifting skin that has lost elasticity and smoothing fine lines. It also adds volume and firmness to nasolabial folds and sunken cheeks, improving skin tone and texture for a combined lifting and anti-aging effect.

Reduces localized fat without surgery.
The principle, in plain words
How does XERF work?
XERF warms the deeper layers of your skin with radio waves. Your skin answers by building new collagen, so it gradually becomes firmer and more lifted.
XERF combines two frequencies — 6.78 MHz and 2 MHz — across 3 depth settings and 10 energy levels. Raising the temperature of deep tissue this way activates fibroblasts and stimulates overall collagen production, creating the tightening, lifting effect.
