Potenza vs Pico Laser: Which Is Better for Acne Scars?

October 25, 2026

Acne scars are one of the main reasons visitors book skin treatments in Korea, and two technologies dominate the conversation: Potenza, a microneedle radiofrequency device, and pico laser, used in a fractional mode for texture. Both stimulate the skin to rebuild collagen, but they reach different depths, suit different scar types and leave you with different recovery. This guide compares them so you can plan sensibly, whether you are in Busan for a week or visiting regularly.

Quick answer: Potenza delivers radiofrequency heat through fine needles into the deeper dermis, so it generally does more for rolling and boxcar scars, enlarged pores and firmness; expect about 3–7 days of redness and grid marks, with sessions every 3–4 weeks. Pico fractional laser creates tiny micro-injuries with ultra-short pulses, which is gentler and suits shallow scars, fine texture and post-acne marks, with mild redness and marks for about 1–2 days. For moderate to deep scars, Potenza is usually the stronger tool; for mild texture or limited downtime, pico fractional laser is easier. Neither erases scars completely, and most people need several sessions.

First, know your scar type

  • Rolling scars: soft, wave-like dips caused by bands pulling the skin down. Often helped by RF microneedling and, where tethered, subcision.
  • Boxcar scars: wider depressions with sharper edges. Respond to collagen-building treatments over several sessions.
  • Ice-pick scars: narrow, deep pits. Hard to treat with any single device; targeted techniques may be needed.
  • Post-acne marks: flat red or brown marks are not true scars. They respond to pigment or redness treatments rather than resurfacing.

Most people have a mix, which is why combination plans are common.

How Potenza works

Potenza is a microneedle RF device. Fine needles enter the skin to a chosen depth and release radiofrequency energy, heating the dermis to trigger wound healing and collagen remodelling. Because energy is delivered below the surface, it can reach deeper scar tissue while limiting damage to the top layer. Different tips allow different depths, and some sessions use "pumping" to push a booster or ampoule into the channels.

  • Best for: rolling and boxcar scars, enlarged pores, mild laxity.
  • Session: about 20–30 minutes after numbing.
  • Recovery: about 3–7 days of redness, tiny grid marks and some flaking.
  • Course: sessions every 3–4 weeks; improvement builds after three or more.

How pico fractional laser works

Picosecond lasers fire extremely short pulses. In fractional mode, a special lens splits the beam into many tiny points that create micro-injuries mainly through a pressure effect rather than heat, prompting the skin to renew. The same laser family is used in low-energy "toning" mode for pigment, which is a different treatment.

  • Best for: shallow scars, rough texture, fine pores, mixed texture and pigment.
  • Session: short, usually with numbing cream.
  • Recovery: mild redness and fine marks for about 1–2 days.
  • Course: usually several sessions spaced a few weeks apart.

Potenza vs pico laser: side by side

  • Depth: Potenza reaches deeper into the dermis; pico fractional works more superficially.
  • Scar severity: Potenza for moderate to deeper atrophic scars; pico for mild scars and texture.
  • Downtime: Potenza about 3–7 days; pico fractional about 1–2 days.
  • Skin tone: both can be used on Asian and darker skin with careful settings, but any heat or injury carries a risk of temporary darkening (post-inflammatory hyperpigmentation), so sun protection matters.
  • Extras: Potenza also helps pores and firmness; pico fractional can improve overall clarity.

Who suits which?

Potenza may suit you if…

  • Your scars are clearly visible as dips under side lighting.
  • You also want pores tightened and skin firmer.
  • You can accept about a week of visible recovery.

Pico fractional laser may suit you if…

  • Your scars are shallow or your concern is mainly rough texture.
  • You have little time for downtime.
  • You want to treat texture and a dull, uneven tone together.

When to wait or choose something else

Treat active acne first; resurfacing over inflamed breakouts is usually avoided. Options for active or recurring acne include extraction, anti-inflammatory injections, Agnes and laser for oil glands. Tethered rolling scars may need subcision. Avoid treatment during pregnancy, with an active infection, or soon after isotretinoin without your doctor's advice.

What it costs in Busan

Listed scar and texture packages at a clinic in Seomyeon include:

  • Full-face pico fractional laser + exosomes 1cc + cryo care + soothing mask : from KRW 129,000
  • Potenza N25 + Juvelook Skin 4cc + soothing care, 1 session : from KRW 390,000, tip charged separately
  • Potenza N25 + Juvelook Skin 4cc + soothing care, 3 sessions : from KRW 990,000, tip charged separately
  • Subcision + Juvelook, 1 area : from KRW 200,000

Prices checked October 2026. They are in Korean won and exclude 10% VAT, which is added at payment. Prices can change, so confirm the current price and the tip cost when you book. Evidence for exosomes in aesthetics is still developing, so treat them as a supportive add-on rather than the main scar treatment.

Results and timeline

  • First 1–2 weeks: skin recovers; it may feel smoother as swelling settles.
  • After 3 sessions: gradual softening of scar edges and pores.
  • Months 3–6: collagen remodelling continues after the last session.

Realistic goals are a visible softening of scars and smoother texture, not perfect skin. Results vary from person to person.

Aftercare and planning around a trip

  • Use a gentle cleanser, regenerating cream and plenty of moisturiser.
  • Protect from UV strictly for 1–2 weeks; Busan's beaches and coastal walks mean strong sun.
  • Do not pick scabs or flakes.
  • Avoid saunas and jjimjilbang, hot baths, hard exercise and alcohol for several days after Potenza, and on the day after pico.

On a short trip, pico fractional laser is easier to fit in because of its shorter downtime. If you choose Potenza, book it early in your stay and keep the last few days light, especially if you plan photos. Flying is generally fine after both, but cabin air is dry, so moisturise on board. Because scars need a course, ask how to continue treatment at home or on your next visit.

Frequently asked questions

Can Potenza and pico laser be combined?

They can be used in the same treatment plan, usually in separate sessions, with Potenza for deeper scars and pico for surface texture or tone. Your doctor decides the order and spacing.

How many sessions will I need?

Most people need at least three sessions of either, spaced a few weeks apart. Deeper scars may need more, plus techniques such as subcision.

Is Potenza painful?

Numbing cream is applied first. Most people feel heat and pressure, strongest over bony areas.

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?
