What Is XERF? The Celebrity Skin-Tightening Trend, and the Korean Alternative
The treatment everyone is asking about
If you have noticed the name XERF appearing across social media and beauty pages recently, you are not alone. Interest in this radiofrequency skin-tightening treatment has grown rapidly this year, helped along by celebrity endorsements and glowing before and after images. Many people are now asking what it is, whether it works, and whether it is worth the price.
In this guide, we explain how XERF works, what you can expect from treatment, and why a growing number of patients are also exploring an exciting Korean alternative: the ALTEON Korean Magic Lift.
What is XERF?
XERF is an energy-based skin-tightening device developed in Korea. It uses radiofrequency energy to heat the deeper layers of the skin in a controlled way, which triggers the body’s natural collagen production.
What sets XERF apart from some older radiofrequency devices is its multi-depth approach. It delivers energy at more than one frequency, allowing it to reach different layers of tissue during the same treatment. Built-in cooling protects the surface of the skin while the deeper layers are heated.
How does XERF work?
As we age, collagen and elastin production slows down. The skin gradually loses its firmness and elasticity, and we start to notice sagging along the jawline, softening of the cheeks and fine lines.
Radiofrequency treatments work by gently heating the deeper layers of the skin. This heat has two effects. First, it causes existing collagen fibres to contract, which can create a subtle tightening effect soon after treatment. Second, it stimulates the fibroblasts in the skin to produce new collagen over the following weeks and months, which leads to gradual, natural-looking firming.
What can XERF treat?
XERF is typically used to address:
- Mild to moderate skin laxity on the face and neck
- A softening jawline and early jowls
- Loss of definition in the lower face
- Fine lines and crepey texture
- Loose skin on areas of the body
Like most energy-based treatments, it works best for people with early to moderate signs of ageing. It is not a substitute for surgery where there is significant sagging.
What is XERF treatment like?
A full-face treatment usually takes around an hour. Patients generally describe a deep warming sensation as the device passes over the skin. Most people find it manageable, and the cooling system helps keep the surface of the skin comfortable.
There is little to no downtime. Some redness or warmth is common immediately afterwards, but this usually settles within a few hours.
When will you see results?
Some patients notice a subtle lifting effect soon after treatment. The most significant results develop gradually over two to three months as new collagen forms. Many providers recommend a single session, with results lasting around a year, although this varies from person to person.
How much does XERF cost?
XERF is positioned as a premium treatment. In London, prices commonly start from around £2,500 for a single session, and can be higher depending on the areas treated.
For many patients, this price point is the main reason they begin looking at alternatives.
The Korean alternative: ALTEON Korean Magic Lift
Korea has become a world leader in aesthetic technology, and the ALTEON Korean Magic Lift is one of the most exciting innovations to arrive in the UK. At Hannah London, we are proud to offer it at our Harley Street and Colindale clinics.
Where XERF relies on radiofrequency alone, the ALTEON Hybrid Lifting Platform combines two technologies in one treatment.
Dual-wavelength laser. Laser energy at two wavelengths, 980 and 1064 nanometres, is used first to warm the skin. This pre-heating stage primes the tissue and optimises the effect of what follows.
Monopolar and bipolar radiofrequency. The platform then uses both types of radiofrequency. Monopolar energy reaches deeper tissue to lift and recontour, while bipolar energy targets more delicate areas, such as under the eyes, with precision.
Fractional modes. Specialised modes deliver energy in columns across the skin’s surface to refine pores, smooth fine lines and improve texture, which is sometimes described as sealing in the results.
Why patients are choosing ALTEON
The ALTEON Korean Magic Lift offers a number of benefits that make it a compelling option:
- Instant and progressive results. Many patients notice brighter, firmer skin straight after treatment, with further improvement as collagen builds.
- No needles and no downtime. It is a genuine lunchtime treatment, so you can return to work or your plans immediately.
- Comfortable. Most patients describe a gentle warming sensation, and no anaesthetic is usually required.
- Versatile. It can lift the jawline, tighten the lower face, brighten the under-eye area and refine skin texture in one session.
- Accessible pricing. At Hannah London, a single ALTEON session is £900, and a course of three is £2,100.
Sessions take around 30 to 45 minutes, and results can last up to two years depending on your skin, age and lifestyle.
Perfect timing for the party season
Because the ALTEON Korean Magic Lift has no downtime and gives visible results from the first session, it is ideal for the months leading up to Christmas. A course started in October or November can deliver firmer, more lifted skin in time for festive celebrations, with results continuing to improve into the new year.
Which treatment is right for you?
Both XERF and ALTEON aim to stimulate collagen and tighten the skin without surgery. The right choice depends on your concerns, your skin and your budget. A thorough consultation is the best way to decide.
At Hannah London, our medical team, led by Dr Kaywaan Khan, will assess your skin, discuss your goals and recommend the treatment plan that suits you best. If you have been curious about XERF, we would be delighted to introduce you to the Korean alternative.
