The Layered lowdown on XERF

When an A-list celebrity declares a specific aesthetic treatment their “new fave,” it’s a bold testament to the efficacy of said treatment—and one that can catapult its popularity ten-fold.

That’s exactly what happened with Kim Kardashian and XERF, the latest K-beauty skin tightening treatment. XERF, a radio frequency device that was developed and initially popularised in South Korea, has recently hit the Western hemisphere, including the UK. So what’s the big deal?

What is XERF, and how does it work?

Radio frequency treatments aren’t exactly new (more on those later), but XERF is reportedly the ‘next big thing’ on the market. This is because it promises noticeable results, a unique approach and a pain-free experience.

“XERF is a non-invasive radio frequency treatment that works by gently heating the deeper layers of the skin to stimulate collagen and elastin production, helping to improve skin firmness over time,” explains Cosmetic Doctor and Dermatology Expert, Dr Sonia Khorana.

The biggest selling point is its dual-frequency wavelengths, which deliver both on-the-surface and deeper tightening of collagen and elastin, meaning multiple layers of skin are targeted. “It not only hits the upper dermis and epidermis of the skin, it is also hitting the SMAS tissue, which is responsible for the structural scaffolding of the skin,” says Celebrity Facialist Nadia Aminian, of Taktouk Clinic.

This makes it ideal for mild to moderate skin laxity and sagging. It is most commonly used on the lower face and jawline, cheeks and neck, where it’s most effective. XERF is a good option for those who are seeking skin tightening and lifting, as well as collagen banking for longer-term healthier skin.

How is XERF different from other radio frequency treatments?

As mentioned, XERF is unique in that it uses dual-frequency wavelengths to deliver impact on multiple levels of skin. Traditional radio frequency approaches such as Thermage don't have this duality, by contrast. The mode of delivery of the energy (and benefits) also differs from the other most popular alternative option, Morpheus8.

“XERF and Thermage are both needle-free treatments that heat the skin from the outside, whereas Morpheus8 combines radio frequency with microneedling, using tiny needles to deliver the energy deeper into the skin. Because of this, Morpheus8 usually comes with more downtime but can be particularly effective for concerns like acne scarring, deeper wrinkles and skin texture. XERF is better suited to people looking for skin tightening and collagen stimulation, with minimal discomfort and downtime".

It also differs from other treatments that aid collagen production and maintenance in the skin, such as Ultherapy or Sofwave; while XERF uses radio frequency, these harness the power of high-intensity focused ultrasound technology.

Why is XERF becoming popular now?

XERF, as mentioned, has caught the attention of celebrities such as Kim Kardashian, which has noticeably given the treatment a boost. While the results are gradual, it’s common to get an instant, temporary lifting and tightening effect from XERF. That, combined with the fact there’s no real downtime, makes it ideal for celebrities who have to attend red carpet events and special occasions regularly.

But the reason the wider world has now become so transfixed by the procedure is not just because of its celebrity appeal, it’s due to the fact it delivers results we’re increasingly seeking.

“There has been a shift away from obvious, dramatic changes towards subtle, natural looking rejuvenation—treatments that help people look refreshed rather than ‘done,’” says Khorana. XERF is a regenerative treatment that does just that, and speaks to our new-found obsession with all things ‘longevity’.

We’re also particularly excited because it’s come from Korea, where many innovative, successful aesthetic techniques now hail from. “The Korean beauty industry is always developing the next generation of lifting and ageing preventing devices,” notes Aminian.

“South Korea is known for being at the forefront of aesthetic technology, with patients often embracing innovative devices early,” adds Khorana. “XERF’s ability to customise treatment depth and target different layers of the skin makes it appealing for a wide range of concerns, from early signs of ageing to more noticeable skin laxity".

Need to know  

As mentioned, one of the biggest appeals of XERF for many fans is that there’s minimal downtime, meaning it can easily be viewed as a ‘lunchtime treatment.’ There may be temporary redness or mild swelling, but generally you’ll be good to go.

While mild warmth and tightening sensations are to be expected during the treatment, it’s relatively discomfort-free, especially in comparison to some similar devices.

In terms of cost, you should expect to pay around £2000+ per session, with 1-3 recommended every 4-6 weeks (depending on area, skin condition and results). Results are gradual, last around a year and will take around 12 weeks to show, although there is a temporary tightening of the skin in the first few days. A yearly maintenance session is often suggested to extend results.
