Pore XERF is a radiofrequency treatment for pores loosened by reduced elasticity, and it cannot make pores disappear completely. Causes related to sebum and dead skin require other treatments alongside it, and the degree of change and how long it lasts vary by individual.

How we approach it

The same device can be run very differently.

Pores differ from person to person, and there is no single reason they look enlarged. The width of the pore itself, surrounding skin that has loosened with reduced elasticity, keratin plugs, trichostasis spinulosa, sebaceous filaments and blackheads overlap.

No single treatment can make pores disappear completely, but most of the causes behind them can be addressed. That is why we place Pore XERF at the centre and recommend a combined treatment matched to the causes.

02What to expect

Changes over time

When XERF's radiofrequency energy delivers a heat stimulus to the dermis, collagen contracts and new collagen forms, reinforcing the support of the skin surrounding the pores.

Right after treatment01

Right after treatment

The skin may be slightly red and warm, but this mostly settles within a few hours.

First week02

First week

Your skin may feel a little dry. Please moisturise more than usual.

Weeks to months03

Weeks to months

As collagen regeneration continues in the dermis around the pores, changes gradually appear.

Combined treatment04

Combined treatment

Causes related to sebum and dead skin are addressed alongside it, in a planned order, with Gold PTT, Potenza and others.

Follow-up05

Follow-up

The next session and combination are decided after re-examining your pores.

06FAQ

Frequently asked questions

What kind of treatment is Pore XERF?

It is a treatment that applies the XERF radiofrequency device to pore concerns. As the heat stimulus causes collagen in the dermis around the pores to contract and regenerate, the aim is for the loosened skin around the pores to become firmer.

Why do pores look enlarged?

There is no single reason. The width of the pore itself, surrounding skin that has loosened as elasticity declines, keratin plugs, trichostasis spinulosa, sebaceous filaments and blackheads overlap to create the appearance. That is why treatment starts with identifying which cause is greatest.

Will Pore XERF alone solve my pores?

Pore XERF mainly addresses pores that have loosened due to elasticity. Areas caused by sebum or dead skin may also need treatments such as Gold PTT, Potenza, GentleMax Pro, skin boosters or LaLa Peel. No single treatment can make pores disappear completely, but by addressing the causes separately, most of them can be improved.

How is it different from XERF used for facial lifting?

It uses the same device, but Pore XERF plans the energy and shot allocation differently, centred on the areas where pores have loosened. If you have both facial sagging and pore concerns, we sometimes address the two together within one plan.

What about pain and recovery?

It is performed after topical numbing cream, and you mainly feel warmth or heat. The skin may be temporarily red after treatment, but in most cases you can return to daily life the same day. How much you feel depends on the area and the individual.

When will I see the effect, and how many sessions do I need?

Because collagen regeneration takes time, changes in firmness around the pores appear over several weeks to months. The number of sessions and intervals depend on your pore condition and any treatments combined with it, so they are explained after examination.

Are there side effects, or cases where it is not suitable?

Temporary redness and warmth may occur, and burns or blisters may rarely occur. If you have an implanted electronic device such as a pacemaker, have metal implants, wounds or infection in the treatment area, or are pregnant, please be sure to tell us during your consultation.

How much does Pore XERF cost, and how do I book?

The cost varies with the number of shots and any treatments combined with it, so it is confirmed after examination. Non-covered treatment fees can be found on the pricing page of our website. Booking and consultations are available via Naver Booking, our KakaoTalk channel, or phone (+82-51-710-1891), and you can also consult with us via LINE.

Fees

Pricing depends on the number of shots and any combined treatments, and is confirmed after consultation.

Aftercare

Radiofrequency lifting

Heat is built up in the dermis to address firmness. Redness and warmth right after treatment usually settle the same day, and normal life resumes from the next day.

Recovery course

  1. Day of treatmentWarmth and redness are expected. Cool the skin gently with a cold towel and moisturise well.
  2. Next dayRedness has mostly faded. Makeup and face washing can continue as usual.
  3. Week 1The skin may feel drier than usual; focus on moisturising and sun protection.
  4. Months 1–3Firmness improves gradually. If treatment is split into sessions, the next one is scheduled in this window.

Precautions

  • Sauna, hot baths, strenuous exercise and alcohol: for 2–3 days after treatment
  • Exfoliating and peeling products: for 1 week

When to contact the clinic

  • Redness has not calmed after 3 days
  • Blisters or weeping appear
  • Pain worsens in one particular area

Next session · next visitDepends on the device and goal, usually every 6–12 months. If areas are treated separately, we will advise at consultation.
