"Is XERF a radiofrequency lifting like Thermage? What's different about it?"
"If I get it once, elasticity comes up right away, right?"
These are questions people who got confused about the types while looking into lifting often ask.
Hello, I'm Director Kwon Si-jin & Yoon Ju-hyun at DA Clinic Myeongdong ^^
We're getting ready to open our doors in Myeongdong soon, and since so many people have been asking about XERF ahead of our opening, we wanted to put together this overview for your information first.
I completely understand that feeling of confusion, since there are so many lifting device names.
But radiofrequency isn't all the same — the methods vary — so choosing without knowing makes it easy to be off the mark. Let me honestly start with what kind of energy XERF uses.
XERF Is a Radiofrequency (RF) Lifting
Let me first unpack the most confusing part.
XERF is a lifting treatment that uses radiofrequency (RF), not ultrasound (HIFU).
If Shurink or Ultherapy is a method of gathering ultrasound into a single point to create heat spots in the deep layers, XERF is a method of heating the dermis with radiofrequency heat to contract collagen.
In the big picture, it belongs to the same 'radiofrequency lifting' family as Thermage.
So if you come in thinking "XERF = ultrasound," there'll be a part that's out of step with the actual principle.
It's the Same Radiofrequency, but 'Dual Frequency' Is Its Feature
So what's different from Thermage?
XERF's feature is a method that uses two different frequencies of radiofrequency together.
The relatively lower frequency delivers energy down to the deep dermis and fiber structure, while the higher frequency acts on the upper dermis near the surface.
Since the concept is dividing the heat delivered to different depths, it's focused on handling multiple depths together, not just one layer.
That said, 'different' doesn't mean 'better'; which method suits varies depending on the skin condition and the purpose.
The Effect Comes in Two Stages: 'Immediate + Gradual'
Many people expect the lifting effect all at once.
A radiofrequency lifting like XERF usually appears in two stages.
First, the heat contracts collagen and a primary tightening appears, and then over the following months new collagen is created and elasticity is added — that's the flow.
So many people feel the change over time rather than on the same day, and the effect isn't fixed permanently.
Since aging progresses even after the treatment, it's more accurate to see it as a concept of managing it periodically while watching your condition. (Response and maintenance have individual differences)
How Are the Pain and Downtime?
Since a radiofrequency lifting heats the deep layers, a sense of heat can be felt.
XERF is a method of cooling the surface with cooling gas during the treatment while heating the inside, so it's a device made with attention to protecting the surface and controlling irritation.
Since it's a non-invasive method, the return to daily life after the treatment is relatively fast, but light redness or a sense of heat can show briefly.
The degree of pain felt and the recovery speed have individual differences, so it's good to understand it as a treatment that 'controls irritation' rather than 'completely painless.'
People in These Situations Should Check One More Time
XERF isn't a treatment casually recommended in every situation.
If you're pregnant or breastfeeding, if you use an electrical medical device like a pacemaker, or if there's a metal implant or active inflammation at the treatment area, it's safer to consult first.
Also, if the cause of sagging is mainly fat or the skin laxity is at a severe stage, radiofrequency tightening alone may not achieve as much change as expected.
So rather than "because lifting is in fashion," the order is to decide the method by looking at the degree and cause of your own elasticity decline.
Frequently Asked Questions
Q. How are XERF, Thermage, and Shurink different?
A. The type of energy and the method differ. Shurink is a method of gathering ultrasound (HIFU) into a single point to create heat spots in the deep layers, while Thermage and XERF are methods of heating the dermis with radiofrequency (RF) to contract collagen. Among these, XERF's feature is using two different frequencies of radiofrequency together to divide and handle multiple depths. That said, rather than any one being superior, the suitable method differs depending on skin thickness, elasticity state, and purpose. So rather than choosing by the device name, it's right to decide the method by looking at your own skin condition. The response differs from individual to individual.
Q. How long does the effect last once I get it?
A. A radiofrequency lifting like XERF tends to show both a primary effect where the heat contracts collagen and a secondary effect where new collagen is created over the following months. So many people feel the elasticity change over time rather than on the same day. That said, since aging continues even after the treatment, the effect isn't fixed permanently, and usually many people manage it periodically while watching their condition. The maintenance period varies depending on skin condition, age, and lifestyle habits, so please keep in mind that there are individual differences.
Q. How do I care for it after the treatment?
A. Since XERF is a non-invasive method, the return to daily life is relatively fast, but light redness or a sense of heat can show for a few days after the treatment. During this period, refrain for a while from activities that raise heat significantly, like saunas, jjimjilbang, and intense exercise, and paying attention to moisturizing and UV protection helps recovery and collagen management. Also, since it takes time for new collagen to be created, it's better to look at the flow over a few months rather than judging the result by how it looks right after the treatment. There are individual differences in the change felt and the recovery speed.
In Closing
If I sum up today's content in one line, it's this.
XERF is a radiofrequency (RF) lifting that uses two frequencies together; the effect appears in two stages, immediate and gradual, and a choice suited to your own skin condition matters more than the device name.
If you got confused about the types of lifting, it's good to start from looking at the cause of your own elasticity decline rather than comparing names. Please also remember that there are individual differences in the result and maintenance.
