Pico Laser in Korea for Melasma and Dark Spots: Pico Toning vs Accento N vs Sylfirm X, Cost and Recovery

Before talking about devices, we need to know what kind of pigment you have. These are the types I see most often:

• Sun spots (solar lentigines) and freckles: clear-edged brown spots on sun-exposed skin. The pigment sits in defined clusters. A targeted laser shot can break it up, a thin crust forms, and it flakes off in about a week.
• Melasma: hazy, blotchy patches, often on both cheekbones, the forehead or upper lip. It is driven by UV, visible light, heat, hormones and an irritated skin environment, including small blood vessels and a weakened lower layer of the skin. It tends to return and to worsen in summer.
• Post-inflammatory pigmentation: darkening after acne, a burn, or an irritating treatment.
• Deeper bluish-brown patches (such as Hori nevus), which sit deeper and need a different schedule.

Many faces have more than one type at once. This is why melasma needs a different approach. Hitting a melasma patch with high energy, the way you would treat a sun spot, can inflame the skin and make it darker (rebound pigmentation). Too-frequent toning at high energy can leave small white spots. Melasma responds better to low energy over several sessions, combined with daily sun protection and calming the skin.

I go through the five pigmentation concerns I see most in this short video.

A pico laser fires pulses lasting picoseconds, trillionths of a second. At that speed the pigment is shattered mainly by a pressure effect rather than heat, into particles fine enough for the body to clear. Less heat around the target means less risk of irritating the surrounding skin, which matters for melasma and for darker skin tones.

At Peachcell we use Picolite Black. It can be used in different ways:

• Pico toning: low energy, wide passes over the whole face. Used for melasma background and dull, uneven tone. No crust, little downtime.
• Spot treatment: higher energy aimed at individual sun spots or freckles. Small crusts form and fall off.
• Pico Fraxel: a fractional mode for texture and scars, a different goal from pigment.

More detail on settings and candidates is on the pico laser treatment page.

These three are often presented as competitors. In my practice they do different jobs, and the melasma plans that work well for my patients often use more than one.

For someone with clear sun spots and little melasma, a spot treatment may be most of the plan. For someone with melasma that keeps returning, especially with redness, I am more likely to start with Sylfirm X and gentle toning, and to leave strong spot treatment for later or skip it. Our signature pigment package combines Accento N, a melasma injection, cryo care, Sylfirm X with exosome LDM, and dual toning across four visits for this reason. You can read more about Accento N on the Accento N treatment page.

Pico laser is a good fit for:

• Sun spots and freckles you want removed
• Melasma, as part of a gentle multi-session plan
• Dull, uneven tone without a single clear cause
• Some post-acne marks, once the acne is controlled

I would wait, or change the plan, if:

• You have a fresh tan or sunburn
• The skin is inflamed, with active eczema, dermatitis or infection
• You are pregnant. Melasma often changes with hormones, and I would rather plan treatment after the pregnancy
• You recently used isotretinoin (acne medication) or have had strong peels. Tell me so I can judge timing
• You expect a single session to clear melasma permanently

Darker skin tones have a higher risk of post-inflammatory pigmentation after any laser. That does not rule pico laser out, but it means lower settings, more spacing and strict sun protection afterward.

When I was director at a clinic in Jeju, I saw how strong sun shapes the skin. People came in with sun spots, freckles, melasma and mixed patterns, often side by side on the same cheek. That is where I learned to slow down at diagnosis. If you treat the wrong type with the wrong energy, the skin tells you within weeks. I talk about this in a short video on the skin concern I saw most in Jeju.

At the KORA Autumn Congress on October 11, 2026, I shared with other doctors how I use pico laser for difficult pigment while protecting the skin barrier, and how to set safer parameters. You can see a bit of the day in this behind-the-scenes clip.

More about my background is on Dr. Ha Chang-ik’s profile page.

1. WhatsApp consultation. Send clear photos in daylight without makeup, from the front and both sides. Tell me how long you have had the pigment, what you have tried, and whether it gets worse in summer.
2. Arrival. Consultation on the 3rd floor, treatment in a private room on the 2nd floor.
3. EVE MUSE 3D scan. This maps surface and deeper pigment and redness, which helps separate melasma from spots.
4. Consultation with me. I decide which type of pigment each area has and which device and energy to use, and I tell you how many sessions I expect.
5. Numbing cream if needed. Pico toning is usually tolerated without it. Spot treatment and Sylfirm X are more comfortable with numbing cream.
6. Treatment. Toning feels like light snapping on the skin. Spot treatment stings briefly at each spot.
7. Aftercare. Soothing care, sunscreen, written instructions, and a WhatsApp follow-up.

Pigment care is priced per session or as a package of sessions. Pico laser is not priced by shots in the way Ulthera is, because the number of pulses depends on the area and the plan.

Results

Sun spots and freckles often lighten clearly after one or two spot treatments, though some come back with sun exposure over time. Melasma improves more slowly. Patients usually notice the patches look softer and the overall tone more even across a series of sessions, not after the first one. Melasma tends to recur, so most people need maintenance and lifelong sun protection. Results vary, and I will tell you what I think is realistic for your skin. One of the cases the clinic has published is a pigmentation package before and after.

Recovery

• Pico toning: mild redness for a few hours. Most people wear makeup the next day.
• Spot treatment: small dark crusts for about 5 to 10 days. Don’t pick them. The new skin can stay pink for a few weeks.
• Sylfirm X: redness and small marks from the needles for a day or two.

Possible side effects include redness, swelling, temporary darkening (post-inflammatory pigmentation), and, with too much energy or too-frequent toning, pale spots. Blisters are uncommon. For a week, avoid saunas, alcohol, smoking and harsh scrubs, and use sunscreen every day.

Here is the honest part for travelers. Spot removal can be done in one visit. Melasma usually needs a series, often every one to a few weeks. If you can visit only once, a realistic plan is to treat clear spots, start melasma care, and continue with a dermatologist at home or on your next trip. I will write down what we did so your doctor at home can follow it.

• Do spot treatment at the start of your trip so the crusts can fall off before you fly, or accept that you may fly with small crusts.
• Plan your sun protection. Sightseeing in Seoul means hours outdoors. Wear a hat and reapply sunscreen.
• Peachcell is near Sinsa Station (Line 3 and Shinbundang Line), open Monday to Friday 10:00 to 20:00 and Saturday 10:00 to 16:00, closed Sunday.

How to check the device

Ask which laser is being used and for what. A clinic should be able to tell you the device name and why it fits your pigment type. At Peachcell we use genuine devices only, and I explain the plan for each area before we start.
