Is XERF a Korean skin tightening treatment?

Yes. What that actually means for the treatment you get, rather than as a marketing label.

In short

  • XERF is a Korean device, and the world-first dual-frequency monopolar radiofrequency system.
  • It runs 6.78 MHz and 2 MHz at the same time, treating shallow, middle and deep layers in a single pass.
  • The Korean approach favours gradual, natural change over one dramatic correction, which is why it suits patients who do not want to look treated.
  • It pairs with Korean Glass Skin, which can be added to a XERF appointment at a reduced price.

The short answer

Yes. XERF is a Korean device, and it is the world-first dual-frequency monopolar radiofrequency system, combining 6.78 MHz and 2 MHz energy in a single treatment. Both the technology and the treatment philosophy behind it come out of the Korean aesthetics market.

Why the Korean part matters

Korean aesthetics is built around a different goal from the one that has historically driven Western cosmetic treatment. The emphasis is on skin quality, structure and gradual maintenance rather than on one large correction. The intended result is that you look rested and well, not that you look like you have had work done.

That shows up in the engineering. Running two frequencies at once is a design decision about treating several tissue depths properly in one pass rather than pushing a single depth harder. The higher 6.78 MHz energy works nearer the surface; the 2 MHz energy reaches deeper structural tissue. Ten intensity levels mean the setting is chosen per area rather than one figure applied across a whole face.

The distinction is not that Korean technology is stronger. It is that it is designed to be more selective, which is what produces a change that reads as natural.

What Korean skin tightening looks like in practice

How it differs from the treatments it is usually compared with

Most radiofrequency skin tightening in the UK works at a single frequency, and radiofrequency microneedling delivers energy through needles that penetrate the skin. XERF does neither. A fuller comparison sits on XERF against Ultherapy and XERF against Morpheus8.

Combining it with Korean Glass Skin

Korean Glass Skin is our signature glow protocol and it addresses what XERF does not: luminosity, tone and surface refinement. XERF works on structure and firmness. Treating both is the closest thing to the complete Korean approach, and Korean Glass Skin can be added to a XERF appointment at a reduced price when the two are booked together. The add-on pricing is on the cost page.

Questions, answered.

Yes. XERF is a Korean device and the world-first dual-frequency monopolar radiofrequency system, combining 6.78 MHz and 2 MHz energy.

It describes an approach that prioritises gradual, natural-looking improvement in skin firmness and quality over a single dramatic correction. In XERF's case that means treating several tissue depths selectively in one pass, with no needles and no numbing.

It is a different design philosophy rather than simply a stronger one. XERF's dual-frequency approach treats shallow, middle and deep layers in the same pass, where most radiofrequency devices work at a single frequency. Which treatment suits you is decided at consultation.

Yes. Korean Glass Skin can be added to your XERF appointment at a reduced price when the two are booked together. XERF works on firmness and structure, Korean Glass Skin on glow and surface quality.
