How Many Sessions Are Needed for Acne Scar Treatment in Korea?

October 25, 2026

Acne scars are one of the most common reasons people look into Korean dermatology, and one of the most common questions is simple: how many sessions will it take? The honest answer is that scars almost always need a course of treatment, and the number depends on the type and depth of your scars, the methods used and how your skin responds. This guide explains what drives that number, typical ranges and spacing, and how to plan a course if you are travelling to Busan.

Quick answer: Most people with acne scars need a course of several sessions rather than one treatment. With Potenza RF microneedling, sessions are usually spaced every 3–4 weeks, with improvement building gradually after three or more. Shallow rolling scars often respond sooner than deep, narrow scars, and some deep or tethered scars need other methods too, such as subcision. Collagen boosters such as Juvelook Skin are often added to support texture. Complete removal of scars cannot be promised, and a doctor can only estimate a realistic number after examining your skin.

Why scars need more than one session

Acne scars form when inflammation damages the collagen in the dermis. Treatments work by triggering controlled repair, prompting the skin to rebuild collagen over the following weeks. Each session adds a little more remodelling to the last, which is why results build gradually and why there is a gap between sessions. Doing too much at once increases the risk of side effects, particularly redness and pigmentation, without making collagen grow faster.

What affects how many sessions you need

  • Scar type. Rolling scars (soft, wave-like dips) often respond well. Boxcar scars (wider, sharp-edged) respond moderately. Icepick scars (deep, narrow) are the hardest to improve with microneedling alone.
  • Depth and number. A few shallow scars on one cheek need less than widespread deep scarring.
  • Tethering. Some scars are pulled down by fibrous bands underneath. These often need subcision, which releases the bands, before resurfacing helps.
  • Skin type and tone. Darker or reactive skin may need gentler settings to lower the risk of dark marks, which can mean more sessions.
  • Active acne. Ongoing breakouts create new marks and scars, so controlling acne first or alongside is important.
  • Your goals. Some people are happy once scars are less visible in normal light; others want more change.

Common methods and typical courses

Potenza RF microneedling

Potenza delivers radiofrequency heat through fine needles into the deeper skin, stimulating collagen remodelling for scars, pores and firmness. A session takes about 20–30 minutes after numbing, with about 3–7 days of skin recovery. Sessions are usually spaced every 3–4 weeks, and scars and pores improve gradually after three or more sessions. Some people with deeper scars continue beyond that.

Subcision

Subcision uses a needle or cannula under the skin to release fibrous bands that tether scars down. It is often done once or a few times for the scars that need it, and combined with a collagen booster or microneedling. Bruising and swelling are common for some days afterwards.

Collagen boosters

Juvelook Skin (PDLLA with hyaluronic acid) is used to encourage collagen for texture, pores and shallow scarring, often in three or more sessions 2–4 weeks apart. It is commonly delivered alongside Potenza or after subcision.

Treating marks, not just scars

Red or dark marks after acne are not true scars. Excel V can help red marks and pico toning can help brown marks, usually over a course every 2–4 weeks.

A realistic timeline

  • First 1–2 weeks after a session: redness and small marks settle within about 3–7 days. Visible scar change is not expected yet.
  • After 2–3 sessions: many people start to notice smoother texture and softer edges in daylight.
  • After 3–5 sessions: clearer improvement for many types of scars. Deep scars may still be visible.
  • Months after the course: collagen continues to remodel, so the final result is often judged several months after the last session.

These are general patterns, not promises. Results vary from person to person.

Planning a course around travel

Scar treatment is easiest if you can return to Korea every 3–4 weeks, or if you live in or near Busan. For visitors, practical options include:

  • One intensive visit: a combination such as subcision with a booster, or Potenza with Juvelook, then continuing sessions at home with a doctor you trust.
  • Return trips: planning visits a few weeks apart, for example combined with business travel or seasonal holidays.
  • A longer stay: a month or more in Busan allows two sessions.

Book Potenza early in your trip so the 3–7 days of redness pass before you fly. Avoid saunas, jjimjilbang, hot baths, hard exercise and alcohol for several days, protect the skin from UV for 1–2 weeks, and avoid tanning in the weeks around sessions.

Frequently asked questions

Can one session make a difference?

Some people notice smoother texture after one session, but scars usually need several. A single session is best seen as a start.

Is there a risk of dark marks?

Yes, particularly in darker skin tones or skin that marks easily. The doctor can adjust depth and energy, suggest a test area, and stress strict sun protection.

Should I treat active acne first?

Usually, yes, or at the same time. Agnes, Accure, extraction and anti-inflammatory injections are options for active or recurring acne.

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?
