I want to get a lift, but I'm worried it might hurt.
For this reason, many people postpone the procedure.

Recently, with the emergence of XERF, a high-frequency lifting device that reduces this burden,
Interest is rapidly growing as an introductory lifting procedure.

Rather than choosing it simply because it is 'new equipment'
It is important to approach this with a precise understanding of the actual effects, pain, and duration.

In particular, recently, as Khloé Kardashian shared her experience with the procedure on social media
Interest is also growing in the global market, and
Inquiries regarding this are also on the rise at K-DOC.

What is XERF Lifting?

SERF uses radio frequency (RF) energy
It delivers heat to the dermis and subcutaneous layers of the skin, and
This is a non-surgical lifting procedure that induces collagen regeneration and remodeling during this process.

Key Points

• Non-invasive procedure performed without skin incision

• Collagen contraction + induction of regeneration (immediate effect + delayed effect)

• You can expect simultaneous improvement in elasticity and skin texture.

3 Key Features of XERF

1) Heat transfer structure with reduced pain burden

The pain from high-frequency lifting occurs during the process of raising the internal temperature of the skin.

XERF applies a cooling system in conjunction with the procedure.
It transmits thermal energy while protecting the epidermis.

result

• Reduced pain sensation

• Mitigating the risk of thermal damage

• Reduced burden of anesthesia possible

2) Energy efficiency and procedure speed

XERF is a structure that distributes and transfers energy over a relatively large area.
You can cover more areas in the same amount of time.

characteristic

• Reduced procedure time (approx. 30–60 minutes)

• Uniform energy delivery across the entire face

• Advantageous for improving skin texture

3) Dual frequency-based multilayer targeting

XERF utilizes different frequencies (6.78MHz & 2MHz) to induce different reactions depending on the depth of the skin.

• Shallow layer (dermis) → Improves fine lines, skin texture, and elasticity

• Deep layer (subcutaneous layer) → Contouring, sagging improvement

It is characterized by the ability to design comprehensive anti-aging effects with a single procedure.

Price structure (per shot)

XERF is generally priced based on the number of shots .

The price is

• Treatment area

• Number of shots

• Medical staff experience

• Hospital Policy

It depends on

General configuration

• 300 Shots → Partial Lifting / Beginner

• 600 shots → Full face / Intensive improvement

Strategic Approach
Initially, after checking the skin reaction with 300 shots
The method of deciding whether to perform additional procedures is reasonable.

Pain · Procedure Time · Recovery

pain

• Individual differences exist

• Often rated lower than conventional high frequencies

Procedure time

• On average, around 30 to 60 minutes

Recovery (Downtime)

• You can resume daily activities immediately after the procedure.

• Makeup available on the same day

However, depending on skin condition
Temporary redness or a sensation of heat may occur.

Side Effects and Precautions

General reaction

• Erythema (reddening)

• sensation of heat

• Mild swelling

In most cases, natural remission occurs within 24 to 48 hours.

Rare but important points to note

• pigmentation

• skin irritation reaction

• Tissue damage may occur if excessive energy is set.

Key Points
'Energy settings and procedure design' determine the results and safety, rather than the equipment itself.

Actual perceived effect

The changes commonly mentioned in clinical and user experience are as follows:

• Jawline and contouring

• skin texture improvement

• Relieves fine lines

• Overall elasticity improvement

characteristic
Rather than drastic changes
Tends to be close to a naturally refined anti-aging result

Maintenance period

• Differences exist depending on individual skin condition, lifestyle, and aging rate.

• Generally, gradual effects are maintained over several months.

reference
Serf is relatively modern equipment
Clinical data regarding long-term maintenance is still in the accumulation phase.

Recommended for these people

If it is your first time getting a lifting procedure
If you are sensitive to pain
If you prefer natural improvement
If you want to minimize the burden of the recovery period
