Hello.
I am the director of Lilive Clinic.

Have you ever looked in the mirror under bright lighting or by a sunny window and suddenly been surprised?
When faced with an unusually rough skin texture and prominent, enlarged pores, you may find yourself sighing without even realizing it.
Today, I would like to explain everything about
“XERF lifting,” which can fundamentally help ease concerns about skin imperfections and reduced elasticity that develop with age.
From the precise definition of lifting to XERF’s key principles and the treatment process, I will organize everything clearly from a doctor’s perspective.

What is the true meaning of lifting?
Many people vaguely understand it as “raising sagging tissue,” but
from a medical perspective, lifting has a somewhat deeper meaning.
What is lifting?
Lifting refers to a treatment that delivers energy such as radiofrequency (RF), high-intensity focused ultrasound (HIFU), or light to the deeper layers of the skin in order to improve skin tissue that has lost elasticity and sagged due to gravity and aging.
This stimulates the regeneration of collagen and elastin.
In other words, it is a non-surgical anti-aging treatment that helps restore elasticity by encouraging the tissues inside the skin to contract and regenerate on their own, without making an incision.

The key principles of XERF
XERF is a premium lifting device that applies dual monopolar radiofrequency (Monopolar RF) technology, an evolution of conventional radiofrequency devices.
- Simultaneous use of dual frequencies: 3.78 MHz + 2 MHz
: Rather than stimulating only the skin’s surface, it simultaneously delivers stable and effective thermal energy from the dermal layer to the deeper SMAS (筋膜) layer.
- Wave Fit Pulse technology
: This maintains powerful energy within the skin for a certain period of time, maximizing the collagen remodeling effect.
- Patent-pending spider-pattern energy delivery
: An exclusive method is used to supply energy evenly across the entire skin, fundamentally preventing side effects such as burns caused by overheating in specific areas.
- Continuous cooling-gas system
: Cooling gas is continuously sprayed between energy applications, helping to significantly reduce pain.

Five distinctive features of XERF lifting
| Feature | Details |
|---|
| 1. Powerful yet safe stimulation | Reaches the deeper layers safely to tighten sagging skin and enlarged pores. |
| 2. Minimized pain | Thanks to the immediate cooling system, even people who are sensitive to pain may be able to receive the treatment comfortably without numbing cream. |
| 3. Three customized modes | Treatment can be customized according to skin type, including fine lines, improved skin texture, dermal-layer elasticity, and lifting of the deeper fascial layer. |
| 4. Natural-looking changes | Collagen continues to regenerate for more than three months after treatment. Because the changes occur gradually, the results do not look unnatural. |
| 5. Excellent duration | Results generally last for approximately six months to one year, and repeating the treatment every six months may produce cumulative anti-aging effects. |

Lilive’s systematic XERF treatment process
STEP 1. One-on-one customized skin assessment
A doctor personally conducts a detailed evaluation of the patient’s facial condition.
The treatment plan is established by considering skin thickness, the degree of sagging, and the presence or absence of volume.
STEP 2. Treatment preparation and numbing (optional)
The process begins with thorough deep cleansing.
Because the device causes little pain, most people can receive the treatment comfortably without numbing.
However, those who are highly sensitive to pain undergo an adequate numbing-cream application process before treatment.
STEP 3. Precise radiofrequency energy delivery
Treatment begins after selecting the optimal mode according to the areas of concern.
For a single treatment, approximately 400–600 XERF shots is generally standard, but the number of shots can be adjusted flexibly according to the individual’s degree of sagging.
STEP 4. Post-treatment care and return to daily activities
Because the skin’s surface is not wounded, you can apply makeup or sunscreen immediately after treatment and return to your daily activities.
For sensitive skin, slight redness may remain for one to two days, but it usually improves quickly.

★ Dr. Park’s “real” review
“Less pain, greater results.”
To get straight to the point, XERF is a device I personally like very much.
Even as a doctor, I am quite sensitive to pain.
That is why I continue my care by periodically performing self-treatments directly on my own face.
(It is almost like conducting an experiment, haha.)
Because it controls pain comfortably while providing a clear tightening effect, it is also the lifting treatment I recommend first to the people around me.

Many people feel that their skin is somewhat tightened immediately after treatment.
As collagen builds over one to three months, you may see clearer skin texture and more refined pores.
If you want to look naturally younger without risky incisions or extreme pain, I would say that XERF can be an excellent option.
