Youthful skin begins deep beneath the surface
Firm, fresh skin has a secret—and it lies deep beneath the skin’s surface. Supportive layers of tissue and a delicate network of Collagen and elastin fibers form the framework that gives the skin its firmness and structure for many years.
Over time, however, the body’s own production of these important building blocks declines. The skin loses its elasticity, contours appear softer, and the first signs of skin laxity become visible.
This is exactly where XERF™ comes in. The innovative Radiofrequency technology uses gentle heat pulses that strengthen existing Collagen fibers while simultaneously stimulating the production of new Collagen and Elastin. This strengthens your Skin structure from the inside out—without any surgical intervention or foreign substances. The result: a naturally firmer, more defined, and more rejuvenated appearance.

About XERF™
Definition of XERF™
XERF™ (short for eXperience Exponential RF) is a state-of-the-art Radiofrequency system for skin tightening that requires no needles or incisions. Instead, the procedure uses heat that is specifically generated in the layers of tissue primarily responsible for your skin’s elasticity and firmness.
Unlike many conventional methods, XERF™ combines two frequencies (6.78 MHz and 2 MHz): one heats the Dermis near the skin’s surface, while the other targets the deeper supporting structures.
The heat activates your skin’s natural repair mechanisms. Collagen fibers that have become slack due to aging contract in response to this stimulation—resulting in a firming effect that is often visible shortly after treatment. At the same time, the heat stimulates the formation of new Collagen and elastin structures. As a result, your skin regenerates from the inside out over the following weeks and appears fresher and firmer again. This natural renewal effect builds up over weeks to months and is long-lasting: the results last up to a year, and often even longer.
Reasons for Skin Tightening with XERF™
The reasons are as individual as our patients. We often see people who have already tried many skincare products and treatments but still want to avoid surgery. Radiofrequency skin tightening was developed specifically for them. These concerns make XERF™ the ideal solution:
- decreasing firmness in the cheeks and neck—or on the body, especially the arms, abdomen, and knees
- early signs of loss of contour along the jawline
- the desire for skin rejuvenation without surgery
- a naturally fresher appearance without long downtime
The common thread is always the desire for renewed freshness and naturalness. The major advantage of XERF™: The treatment strengthens and reactivates what is already there—and adds nothing foreign.
The Goal of XERF™ Treatment
Our goal is for your skin to regain its natural firmness and elasticity after XERF™ Treatment, without your face appearing altered in any way.
Your facial contours become more defined, your skin’s surface becomes visibly and tangibly smoother, and your overall appearance becomes more vibrant. Since the results develop gradually, they appear harmonious and authentic. People around you will notice the change less noticeably than they would after surgery or a Filler Injection.
For us, subtle naturalness is always the top priority: The improvement should be positively noticeable—but never seem forced or artificial.
The XERF™ Treatment Process
Preparation for the Treatment
Before the treatment, we invite you to a personal consultation. In a discreet setting, our specialists will examine your skin, listen to your wishes, and assess which areas are suitable for Non-invasive skin tightening with XERF™. This allows us to create a treatment plan tailored specifically to you. Of course, we will also explain the expected costs as well as any potential risks and Side effects.
Conducting the XERF™ Treatment
During the treatment, you’ll get comfortable on our treatment table. We gradually move the handpiece over the areas discussed beforehand. The multi-frequency radiofrequency energy specifically heats the deeper layers of tissue—you’ll hardly feel anything, at most a pleasant sensation of warmth. The built-in cooling mechanisms protect your skin’s surface at all times. Depending on the area, a session lasts about 30 to 60 minutes.
Aftercare
After the session, you can resume your daily routine immediately. Your skin may be slightly red at first, but this will subside quickly. No extensive skincare or recovery periods are required. We simply recommend that you avoid direct sunlight and tanning beds for the first few days and use a good sunscreen (ideally SPF 50+).
The full effects become apparent in the weeks that follow, as your skin builds new Collagen. We’ll support you throughout this period and schedule additional sessions on an individual basis as needed.

Frequently Asked Questions About the XERF™ Treatment
Which areas is XERF™ suitable for?
We achieve particularly good results on the face—such as along the jawline and on the cheeks—as well as on the neck and décolletage.
Who is a good candidate for XERF™ skin tightening?
For women and men who want to treat early or already visible signs of skin laxity without undergoing surgery. During the consultation, we’ll determine whether the treatment is right for you.
When will the first results be visible?
You’ll often notice an initial rejuvenating effect shortly after your treatment at KALEIDOSCOP in Zurich. The actual Skin tightening develops over several weeks, as the formation of new Collagen takes time.
How long do the results last?
The skin-tightening effect is caused by the body’s own collagen production and is therefore long-lasting—the results last up to a year, and often even longer. Since the skin naturally continues to age, the effect can be maintained permanently with regular maintenance treatments.
Is the XERF™ treatment painful?
No. Thanks to the built-in cooling system, most of our patients find the treatment comfortable. The only sensation is a warm feeling on the skin.
Are there any risks or Side effects?
XERF™ is considered a very gentle procedure. You may experience temporary redness or a slight sensation of warmth—both of which, based on our experience, subside quickly.
Is downtime required after the treatment?
No. The treatment involves no incisions and requires no recovery period. You’ll be ready to go out in public right away and can resume your daily activities without restriction.
How much does a XERF™ treatment cost in Zurich?
The first 100 clients can take advantage of our introductory offer starting at CHF 1,500 per Session. The exact cost depends on the area to be treated and the scope of the procedure—after a personal consultation at KALEIDOSCOP in Zurich, we’ll provide you with a transparent quote.
