Agnes RF Treatment in Busan: Acne and Sebaceous Gland Care

October 25, 2026

Agnes is a Korean-developed radiofrequency treatment that has become a go-to option for acne that keeps returning in the same spots. Instead of treating the surface, it targets the oil gland underneath, one gland at a time. This guide explains how Agnes works, who it suits, what recovery looks like and how to plan it around a stay in Busan.

Quick answer: Agnes places a very fine needle, insulated along its shaft, into an individual oil gland and releases radiofrequency energy only at the tip, damaging the gland while largely sparing the skin surface. It suits acne that recurs in fixed places such as the chin, jaw or cheeks. Treatment takes about 20–30 minutes after 30 minutes of numbing cream, recovery is about 3–7 days, and sessions are repeated every 3–4 weeks if needed. In Seomyeon, the price depends on the area and number of glands, so it is quoted at consultation.

What is Agnes and how does it work?

Acne starts in the pilosebaceous unit: the oil gland and hair follicle. When a gland is overactive, excess sebum, dead skin and bacteria lead to repeated inflammation in the same spot. Agnes is designed to reduce that gland's activity.

The device uses microneedles that are insulated along their length and conduct energy only at the uninsulated tip. The doctor places the needle at the depth of the oil gland beneath a recurring lesion and delivers a short pulse of RF heat. Because the shaft is insulated, the skin the needle passes through is protected, which limits surface damage and helps healing.

Why "gland by gland" matters

Agnes is not a full-face resurfacing treatment. Its precision makes it useful for a limited number of stubborn spots, rather than for acne spread evenly across the face. The same insulated-needle technology is also used by some doctors for other small targets, such as certain under-eye fat pockets or small bumps, but acne glands are the main use discussed here.

Who is Agnes for?

  • People whose acne returns in the same spots again and again.
  • People with a few deep, stubborn breakouts on the chin, jawline or cheeks.
  • People with oily skin and enlarged pores in limited areas.
  • Anyone who can allow 3–7 days of visible recovery after each session.

When something else may suit better

  • Widespread breakouts: a laser that treats oil glands across an area, such as the Accure laser (1726 nm), may be more practical.
  • A hot, painful spot right now: an anti-inflammatory injection usually calms it first.
  • Blackheads and congestion: medical extraction and peels.
  • Acne under control but dents remain: Potenza RF microneedling for scars and texture.
  • Small yellowish bumps with a central dip: these may be sebaceous hyperplasia (harmless enlarged oil glands), which is usually removed with a precise laser instead.

Who should not have Agnes

Radiofrequency may not be suitable if you have a pacemaker or other implanted electronic device. It is usually postponed during pregnancy, with an active infection or cold sore, or with a bleeding disorder or keloid tendency. Tell the doctor about blood thinners and any recent isotretinoin use.

How much does Agnes cost in Busan?

Agnes is priced by the area, the number of glands treated and the number of sessions planned, so there is no fixed online price at the clinic in Seomyeon; it is quoted on WhatsApp or at consultation. For comparison, related acne care in Seomyeon includes:

  • Black Peel + extraction + ultrasound care : from KRW 89,000
  • Aqua Peel + acne extraction + anti-inflammatory injection, 5 sessions : from KRW 290,000
  • Potenza N25 + Juvelook Skin 4cc + soothing care, 1 session : from KRW 390,000 (tip charged separately)

Prices checked October 2026. They exclude 10% VAT, added at payment. Prices can change, so confirm the current price when you book.

What happens during a session

  1. Before you arrive. Send photos showing where acne keeps returning, and mention any implanted devices and acne medicines.
  2. Consultation. The doctor maps the recurring spots, checks which are inflamed and decides how many glands to treat that day. Very inflamed lesions may be calmed first.
  3. Numbing. The skin is cleansed and numbing cream is applied for about 30 minutes.
  4. Treatment. The insulated needle is placed into each target gland and energy is released at the tip. It takes about 20–30 minutes; most people feel pricking and brief heat.
  5. Soothing. The skin is calmed, and you can go out the same day.

Results and timeline

  • Days 1–7: redness, small needle marks and mild swelling settle.
  • Weeks 2–4: treated spots tend to break out less.
  • After several sessions: many people see fewer recurring lesions.
  • Following months: improvement may continue.

Agnes aims to reduce acne from the specific glands treated, but lasting results cannot be promised. Hormones, stress, skincare and other glands can still cause new breakouts elsewhere. Clinical studies of insulated-needle RF for acne are encouraging but relatively small, so think of it as one useful tool rather than a cure.

Side effects and aftercare

Common effects are redness, swelling and small needle marks or scabs for about 3–7 days, plus bruising if you bruise easily. Some people have a temporary flare of breakouts. Rarely, temporary darkening or small depressed marks occur.

Aftercare tips

  • Do not pick scabs or flaking skin.
  • Protect the skin from UV thoroughly for 1–2 weeks.
  • Follow the clinic's guidance on washing and makeup for the first day.
  • Avoid saunas, jjimjilbang, hot baths, hard exercise and alcohol for several days.
  • Use a regenerating cream and moisturiser generously.

Planning Agnes around a trip to Busan

You can walk around and sightsee the same day, but small marks may be visible for a few days, so book Agnes early in your stay and leave time before important photos or events. Flying is generally fine; moisturise on the plane. If you need more than one session, they are usually 3–4 weeks apart, which suits people who visit Busan regularly or can combine Agnes with treatment at home. Tell the doctor your flight date so the plan fits.

Agnes vs other acne treatments

  • Agnes : insulated RF needle into individual glands. Best for: acne recurring in the same spots.
  • Accure laser : laser energy absorbed by sebum across an area. Best for: scattered recurring acne and oily skin.
  • Potenza : RF microneedling over an area to remodel collagen. Best for: acne scars, pores and firmness once acne is controlled.
  • Extraction and anti-inflammatory injection : quick care for active spots. Best for: congestion and painful flares.

Frequently asked questions

Does Agnes hurt?

Numbing cream is applied for about 30 minutes first. You may still feel pricking and brief heat with each pulse, but most people find it tolerable.

How many sessions will I need?

Many people need more than one session, spaced 3–4 weeks apart. The number depends on how many glands are involved and how active the acne is.

Is Agnes permanent?

A treated gland is less likely to cause repeat breakouts in that spot, but new acne can still develop elsewhere, so results are not guaranteed to be permanent.

Ultherapy is one of the most requested non-surgical lifting treatments in Korea, and Busan has become a popular place to have it done, especially for visitors who want to combine a treatment with a city break by the sea. This guide explains how Ultherapy works, who it suits, what it costs in Busan, and what recovery really looks like, so you can decide whether it fits your goals and your travel plans. Quick answer: Ultherapy uses focused ultrasound, guided by real-time imaging, to heat the deep supporting layer of the face (the SMAS) and trigger new collagen. A session takes about 30–60 minutes after numbing cream, there is usually no downtime, the lift builds over 2–6 months, and results typically last 6–12 months. In Busan, packages generally start from around KRW 790,000 before 10% VAT. What is Ultherapy? Ultherapy (often called Ulthera) is a micro-focused ultrasound device made by Merz Aesthetics. Like other HIFU treatments, it delivers concentrated ultrasound energy beneath the skin. What sets it apart is its built-in imaging: the practitioner can see the layers of the skin on screen and place each line of energy at the intended depth, including the SMAS, the same layer that is tightened in a surgical facelift. Each line creates tiny heated points that contract the tissue and start the body's collagen renewal process. Rather than an instant change, the skin firms and lifts gradually over the following months. Benefits of Ultherapy Reaches the deep support layer. Energy can be delivered down to the SMAS, which is why Ultherapy is used for sagging rather than surface texture alone. Imaging-guided precision. Seeing the tissue before each line helps place energy where it is needed and away from bone. No incisions and no downtime. Most people return to their day straight away. Natural, gradual change. The lift develops as collagen rebuilds, so results look like your own face, only firmer. One session a year for many people. A single treatment is usually enough for a visible change, repeated every 6–12 months. Who is a good candidate? Ultherapy tends to suit people in their 30s to 60s whose cheeks, jowls or brows have started to drop, or who have a softer jawline and some looseness under the chin. It is less helpful when the main concern is crepey texture rather than sagging (radiofrequency treatments such as Thermage FLX often suit that better), or when the face is very thin and hollow, in which case restoring volume may matter more than tightening. How much does Ultherapy cost in Busan? Ultherapy is priced by the number of lines (shots). Around 300 lines is typical for targeted areas such as the jawline and lower cheeks, while around 600 lines allows fuller coverage of the face and under the chin. In Busan, Ultherapy is often sold as a package combined with a skin booster or skin Botox. Ultherapy 300 lines + full-face skin Botox : from KRW 790,000 Ultherapy 600 lines + full-face skin Botox : from KRW 1,690,000 Prices checked October 2026. Korean clinic prices for cosmetic treatments are quoted in won and exclude 10% VAT, which is added at payment. Prices can change, so always confirm the current price when you book. When comparing quotes, check the number of lines included, whether the device is genuine Ultherapy or Ultherapy PRIME rather than a different HIFU machine, what is bundled in the package, and whether VAT is included in the figure you were given. What happens during a session Consultation. The doctor assesses sagging, fat and skin thickness, then plans the areas, depths and number of lines. Numbing. Numbing cream is applied for about 30 minutes, then the skin is cleansed and a gel is applied for the imaging probe. Treatment. The transducer shows the skin layers on screen and delivers focused ultrasound over about 30–60 minutes. Areas close to bone, such as the jawline, can feel prickly or warm. Straight back to your day. Mild redness is common and usually fades within hours. Results: what to expect and when Right after treatment: some people notice slight tightening; mild redness is normal. Months 2–3: lifting and firmness become visible as collagen renews. Months 3–6: results usually reach their peak. Months 6–12: the effect gradually fades with natural ageing; a repeat session maintains it. Results and timing vary from person to person. Even, well-planned coverage matters more for a natural result than simply using the maximum number of lines. Recovery, side effects and aftercare Ultherapy has very little downtime. The most common effects are redness or mild swelling that settles within hours to a few days, and tenderness or a bruised feeling along the jaw that can last a few days. Rarely, people experience temporary numbness, small bruises, welts or nerve irritation. Aftercare tips On the day of treatment, avoid saunas and jjimjilbang, hot baths, alcohol and strenuous exercise. Use sunscreen carefully for 1–2 weeks and avoid rubbing or scratching the treated area. Keep the skin well moisturised; makeup can usually be applied once the skin has calmed. Who should wait or avoid it Ultherapy is not recommended during pregnancy, over an active skin infection, open wound or severe acne in the area, or near metal implants or a pacemaker. Tell your doctor about any recent fillers, threads or other procedures in the area. Planning Ultherapy around a trip to Busan Because there is no real downtime, Ultherapy fits easily into a short stay. You can usually go sightseeing the same afternoon, and flying is generally fine, although jaw tenderness can feel more noticeable when chewing on the plane. Booking the treatment early in your trip gives you a few days to settle before you fly home. Share your flight date at the consultation so the plan fits your schedule. Ultherapy vs other lifting options Ultherapy : Focused ultrasound with real-time imaging. Best for: sagging cheeks, jowls and brows. Ultherapy PRIME : Newer Ultherapy platform with upgraded imaging. Best for: the same goals on the latest hardware. Thermage FLX : Monopolar radiofrequency heating the deep dermis. Best for: crepey skin and overall firmness. Shurink Universe : HIFU at set depths, without imaging. Best for: jawline and budget-friendly maintenance. In short, choose Ultherapy for an imaging-guided lift of deeper sagging, Thermage FLX when skin texture is the bigger concern, and Shurink Universe for more frequent, lower-cost upkeep between sessions. Frequently asked questions Does Ultherapy hurt? Most people describe it as warm, prickly pulses, strongest over bony areas. Numbing cream is applied beforehand to keep it comfortable. How many sessions will I need? One session is usually enough for a visible change. Many people repeat it every 6–12 months to maintain the result. Is 300 or 600 lines right for me? 300 lines generally focuses on priority areas such as the jawline and lower cheeks, while 600 lines covers the full face and under the chin more thoroughly. The right number depends on your degree of sagging and the areas you want treated. Thinking about Ultherapy in Busan?
