Pico Toning or IPL for Melasma in Gangnam?

Whether pico toning or IPL fits your melasma depends less on the device name and more on the type and depth of your pigment. Laser and light treatments can lighten melasma faster, but they are not a cure, and post-inflammatory darkening and recurrence are real factors to plan around. We recommend starting with an exam that separates melasma from other spots, then building a plan that includes topical treatment and sun protection from the outset.

Hello, I am Dr. Kim Yeon-jin, Chief Physician at UHCELL Clinic Gangnam. When patients look into melasma treatment, pico toning and IPL are usually the first two names they hear. Here I want to walk through how we actually decide between them, and what the research supports and does not support.

First, Separate Melasma from Other Spots

Before we talk about any device, we need to know what kind of pigment is on the face. Melasma is a long-lasting, recurrence-prone pigment condition. Cleveland Clinic describes it as brown or blue-gray patches that sunlight makes worse. Other spots, often grouped as general pigmentation or freckling, tend to have clearer borders and can sit on the same face alongside melasma.

Depth matters as much as type. The American Academy of Dermatology notes that tools such as a Wood’s lamp or dermoscope are used to check how deep the pigment sits in the skin, and that this information is genuinely useful for planning melasma treatment. At our clinic, we diagnose the individual’s skin first and design the procedure around it. Separating melasma areas from other pigmented areas is where that process starts.

Pico Toning and IPL Deliver Energy Differently

Pico toning uses a laser that emits very short pulses, measured in picoseconds (trillionths of a second), applied broadly at low energy over repeated passes. IPL is different from a single-wavelength laser: it uses a broad band of light made up of multiple wavelengths at once.

	Pico Toning	IPL
Energy delivery	Picosecond laser pulses, low energy, repeated passes	Broad-band light with multiple wavelengths
Melasma-related evidence	In a split-face randomized trial, results were comparable to a nanosecond laser, with less pain and a lower reported chance of melasma flare-up	Listed by Cleveland Clinic as one of several light-based options for melasma
Point to watch	Frequent repeat sessions with conventional 1064nm laser toning have been linked to reports of white spots (guttate hypomelanosis)	Shares the same pigmentation-darkening and rebound-worsening risk as other laser and light treatments

The pico toning evidence comes from a melasma treatment review published in Annals of Dermatology, the journal of the Korean Dermatological Association. That review cites a randomized trial by Feng and colleagues that compared a 1064nm picosecond laser against a nanosecond laser on opposite sides of the same face. Improvement in melasma was similar between the two, while the picosecond laser caused less pain during treatment and carried a lower reported chance of flare-up. The same review also addresses a separate concern: frequent, closely spaced sessions of conventional 1064nm laser toning have been associated with melanocyte damage that can show up as white spots. That is why we set the interval between sessions and the total number of sessions together, at the planning stage, rather than leaving it open-ended.

IPL is also used for melasma. Cleveland Clinic groups IPL together with non-ablative fractional lasers and low-fluence Q-switched lasers as light-based options for the condition. The pigmentation-darkening and recurrence risks described below apply to IPL in the same way.

What Laser and Light Treatments Can Actually Do for Melasma

Lasers can lighten melasma faster, but that speed comes with added risk. A 2024 meta-analysis by Ingyu Lee and colleagues, published in the Journal of Cosmetic Medicine, analyzed 15 randomized controlled trials comparing chemical peels and lasers in melasma patients. Laser produced a larger reduction in melasma severity (standardized mean difference of 0.82) than chemical peels (0.65). However, laser also carried a higher risk of post-inflammatory hyperpigmentation, particularly in Fitzpatrick types IV-VI, which describes medium-to-deep skin tones. The authors concluded that chemical peels, while slower, may be the safer option for patients who are concerned about side effects.

Recurrence is the other factor to plan for from the start. A 2017 review by Trivedi and colleagues in the International Journal of Women’s Dermatology explains that laser and light treatments can speed up the clearing of melasma pigment but do not cure it. According to that review, roughly 50% of patients experience some degree of recurrence within 3-6 months after treatment, regardless of which device was used. The review also found that combining procedures with topical treatments that suppress pigment production produced better outcomes, and recommends starting topical treatment at least 2-6 weeks before the procedure if the patient is not already on one.

The American Academy of Dermatology reaches the same conclusion from a different angle: there is no single best treatment for melasma, and the most effective approach combines sun protection and topical medication, sometimes with a procedure added. The Academy also notes that adding laser or light treatment on top of existing topical medication and sun protection has shown better results in some studies than either approach alone. For that reason, when a patient has melasma, I tend to look first at a plan that layers topical treatment and sun protection and introduces energy-based treatment carefully, rather than one that tries to clear the pigment in a single high-energy session.

If You’re Visiting Seoul for a Short Stay

Melasma does not resolve in one session. If your time in Seoul is short, it is more realistic to treat this visit as the start of diagnosis and planning rather than the end of treatment. Since the research above points to starting topical treatment 2-6 weeks before a procedure, it helps to discuss a melasma management plan with a local physician in your home country before you travel, if that option is available to you. If you have both melasma and other spots, we can use the consultation to decide which area to address now and which to monitor over time.

What to Tell Us Before Your Consultation

To build an accurate plan, we need the following information. Photos are enough for most of it.

1. When the pigment first appeared, and whether it darkened with summer sun, pregnancy, or hormonal medication
2. The names of any whitening products or medications you are currently using or taking (a photo of the product or packaging works)
3. Any past experience where laser, toning, or peeling made your pigment darker, or caused white spots
4. Your departure date and any outdoor plans during your stay
5. A photo of your bare face in natural, bright light

If your skin looks darker after a procedure, or you notice white spots, do not add more whitening products at home. Please come in for a review. Pigmentation-darkening and rebound-worsening are recognized responses to laser and light treatment, and the plan may need to be adjusted.

Care at Our Gangnam Clinic

Our Gangnam location is on the 2nd and 3rd floors of the WD Building at Teheran-ro 8-gil 13, inside the UH FLAT SIGNATURE Gangnam hotel building. Procedures are done in private rooms, and we have Japanese, Chinese, and English-speaking staff on site, so details like pigment type, timing, and past treatment history can be discussed in those languages as well.

If you are staying at UH FLAT SIGNATURE Gangnam, you can return to your room in the same building to rest after your procedure.

FAQ

Will one session of pico toning clear my melasma?

No. Melasma does not resolve with a single treatment. According to the Trivedi et al. review, roughly half of patients see some recurrence within 3-6 months after laser or light treatment. Plan the number of sessions, maintenance, and sun protection together from the start.

Can I get IPL if I have melasma?

IPL is one of the light-based treatments used for melasma. Laser and light treatments in general carry a shared risk of pigmentation-darkening and rebound-worsening, and the Lee et al. meta-analysis found that laser’s pigmentation-darkening risk was particularly elevated in Fitzpatrick types IV-VI. We assess this during the exam, separating melasma from other spots and factoring in whether a previous treatment ever darkened your skin.

What should I continue after I return home?

Sun protection and topical treatment. The American Academy of Dermatology states that the most effective melasma treatment is the combination of sun protection and topical medication, with procedures added on top. We recommend continuing your topical prescription and follow-up with a physician near you.

If you have both melasma and other spots and are not sure which to treat first, bring the information above to a consultation at our Gangnam location. We will separate the pigment types first and build a plan around your travel schedule.
