Melasma, dark spots and freckles: should you choose toning, pico toning or IPL?

Key summary

For melasma, sun protection and topical treatment are the basics, with toning added as needed, while freckles or sun-induced age spots are treated by considering IPL and pigment lasers. When multiple types of pigmentation are present together, a specialist examines the lesions and skin condition to decide which area to treat first and by which method.

01 How do specialists distinguish between melasma and age spots?

The brown marks commonly called age spots actually involve several different skin conditions. A flat brown spot that develops on an area that has received long-term sun exposure is called solar lentigo, while a brown mark left behind after inflammation or a wound has healed is called post-inflammatory hyperpigmentation. These must also be distinguished from melasma and freckles, so dermatology clinics first diagnose the type of abnormal area on the skin, that is, the lesion. If melasma is spread widely across the cheeks and a lentigo is visible on top of it, the two lesions are treated under separate treatment plans.

Sinsa Kim Dong-ha Dermatology Clinic explains in its pigment treatment information that it examines the type and depth of pigmentation using Markview testing and a magnifying lens. Markview is a skin diagnostic device this clinic uses to differentiate pigment types, and in addition to the exam, the clinic also asks about lifestyle habits and prior treatment history. The official profile of Director Kim Dong-ha lists board certification in dermatology and a doctoral degree in dermatology.

Lumin Dermatology Clinic introduces board-certified dermatologist and director Choi Jae-won as the physician in charge of pigment treatment on its pigmentary disorders page. The clinic explains that it varies the wavelength of light used and the exposure time per pulse depending on which layer of the skin the pigmentation is located in.

02 How do toning, Pico toning, and IPL actually differ in treatment?

Toning uses a laser applied repeatedly at low power over a wide area. The Q-switched Nd:YAG laser used in standard toning is a type of laser that fires light in short bursts, while pico toning uses a laser that delivers light in even shorter pulses, measured in picoseconds. A picosecond is one-trillionth of a second. The explanation that the light-delivery time is short should be kept separate from the judgment that it is more suitable for your particular melasma.

Unlike lasers, IPL uses light across multiple wavelength bands. Wavelength is a value that distinguishes the characteristics of light, and IPL uses a filter to select the needed wavelength range before applying it to the skin. When clinicians refer to the treatment area, they mean the area of skin the light is applied to, and a handpiece refers to the handle-shaped component that delivers the light toward the skin. MLA, which connects to a pico laser, is a micro-lens component that splits light into many small points.

2026-10-19 clinic's official treatment guidance standard. Revlite, PicoSure, and Enlighten are laser device names, and SelecV and M22 are IPL device names. Withwin Dermatology Clinic explains in its M22 treatment guidance that it adjusts the filter and intensity according to skin condition.

03 How is treatment order decided when melasma and lentigo occur together?

Let's look side by side at a patient case that treated lentigo first and the clinical principle of managing melasma first. Here, mixed pigmentation refers to a condition where different pigment lesions, such as melasma and lentigo, occur together.

A case that treated lentigo first and continued with toning afterward

Lumiin Dermatology Clinic introduced a woman in her 40 who had dark spots, melasma, and blemishes together on her cheekbones and under her eyes. According to the clinic's description, the dark spots were treated first with one session of Re-pot laser, followed by 10 sessions of laser toning, during which the pigmentation gradually lightened. This is a case that addressed the clearly defined spots first and then continued with toning for the more widely spread pigmentation.

An approach that first examines melasma and skin irritation before treating dark spots

The mixed pigmentation case from Sinsa Kim Dong-ha Dermatology Clinic describes dark spot treatment using the Enlighten picosecond laser with an MLA lens. The clinic explains that after treatment, a wound-protective dressing called Duoderm was kept in place for 2 weeks, and a regenerating cream along with a pigmentation-prevention product were applied.

The treating physician explains that when melasma and dark spots overlap, melasma is usually stabilized first. The clinic's pigmentation treatment guide explains that they check whether the skin is red or stinging to determine when to pause laser treatment. In other words, this is an approach that manages melasma and skin irritation first, before treating dark spots right away. Dark spots in areas without melasma may be treated first, and the clinic also notes that it monitors for a temporary darkening reaction of melasma after dark spot treatment.

The photos were taken on 2024-11-23 and 2025-05-31. This represents a progression of about 6 months, and the interval between the two photos does not itself represent the number or spacing of treatment sessions. Since the patient and treatment composition differ from the earlier Lumiin Dermatology Clinic case, these cases should not be used as material for comparing effectiveness between clinics.

04 What changes if the skin is sensitive or has redness?

If your skin has both deep melasma and white patches, you need to look at each change separately. The melasma case of a woman in her 50 published by Shinsa Kim Dongha Dermatology Clinic shows areas of hypopigmentation mixed in, where the skin is lighter than the surrounding area. The clinic explains that it performed Revlite SI toning 5 times, Sylfirm X 5 times, and Ionzyme care. Sylfirm X is a device that delivers radiofrequency energy through micro-needles, and Ionzyme is a program the clinic introduces together as a moisturizing care.

The clinic stated that after treatment the melasma lightened, but the hypopigmented areas remained in part. The skin as a whole becoming brighter and the white patches recovering are two different changes. This case, too, is the course of combination treatment rather than toning alone.

Redness is a symptom in which the skin appears red, which is distinguished from brown pigmentation and its treatment target. In the case of a woman in her 30 with melasma, blemishes, and redness, Lumin Dermatology Clinic explains that after examining the condition with a Mark-Vu, it used Revlite and PicoSure for the pigmentation and V-beam and SelecV for the redness. V-beam is a laser that targets blood vessels, and SelecV is the IPL device explained earlier. The course the clinic described was about 6 months.

Withwin Dermatology Clinic explains in its redness treatment guide that it adjusts the number of sessions and intensity of IPL according to the skin condition, and that dermatologist and lead director Lee Jae-bong performs the procedure directly. This is the clinic's treatment policy, not the treatment outcome of an individual patient.

05 Which procedure is right for my skin?

When consulting, talk about the areas that concern you most and any changes after previous procedures. Diagnosis should be left to the specialist, but if you convey your specific concerns, it becomes easier to set treatment goals together.

Is it widespread pigmentation, or a distinct spot?

If diagnosed with melasma, discuss with your doctor whether sun protection and topical medication alone will do, or whether you need laser treatment added. If it's well-defined freckles or solar lentigines, consider IPL or pigment lasers. If both are mixed, ask your doctor to explain which areas will be treated with which approach before repeating a single procedure across the whole face.

Do you flush easily, or does discoloration linger after procedures?

Tell your doctor specifically whether you sunburn easily, whether your skin stings when you apply cosmetics, and whether discoloration lingered for a long time after a previous laser treatment. Lumin Dermatology Clinic's 20 freckle case explains that laser toning was chosen in consideration of thin, sun-sensitive skin. This is an example of how, even with the same diagnosis of freckles, the approach applied can differ depending on how the skin reacts.

Are you more concerned about improving individual spots, or about your overall skin tone?

Tell your doctor whether a few particular spots bother you the most, or whether widespread melasma and blotchiness are the concern. If you treat individual lentigines, you also need to consider your daily life while wearing a protective wound dressing. If you separate the spots you want to reduce right away from the melasma you'll manage over the long term when consulting, you can decide together which areas to treat and what the recovery process will look like.

06 What should you know before the procedure?

Check both the dermatologist's qualifications and the specific field each doctor handles at the clinic. Lumin Dermatology Clinic's meet the medical staff page distinguishes Dr. Choi Jae-won's pigmentation and lifting practice, Dr. Yoon Ji-seon's acne and skin texture practice, and Dr. Choi Ji-ho's vitiligo and psoriasis practice. The pigmentation treatment page is linked to Dr. Choi Jae-won, the lead director. Ask who will actually handle your diagnosis and procedure when you book your appointment.

The topical treatment mentioned in the Key summary doesn't refer to whitening cosmetics in general. The American Academy of Dermatology explains that melasma treatment may involve hydroquinone or prescription creams combining several ingredients, with the medication chosen based on the patient's skin condition. Since topical medication is also part of the treatment plan, let your doctor know about any products and prescriptions you're currently using.

In daily skin care, consider not only ultraviolet light but also visible light, which is light you can see. Tinted sunscreen refers to products that contain color pigment, and the American Academy of Dermatology provides guidance on products among these that contain iron oxide. If a product causes stinging or burning on the skin, adjust use to reduce irritation, and ask about the appropriate timing for washing your face, applying makeup, and removing dressings after a procedure based on the treatment you received.

07 How did studies compare toning and pico-toning?

There is also research examining whether pico-toning works better than regular toning for melasma. A comparative trial published in 2026 randomly assigned 16 Asian women to receive picosecond treatment on one side of the face and Q-switched Nd:YAG treatment on the other side. Both treatments used a 1064nm wavelength, with nm being the unit of nanometers that indicates the wavelength of light. Treatment was given three times at 4-week intervals, with follow-up through 6 months, and the scores below are values that evaluated the extent and darkness of melasma on each half of the face. A lower score means less melasma.

These are average values confirmed in Table 2 of the original 2026-10-19 study. Both sides showed lower scores, but the study did not find a clear enough difference to determine which method improved more. Concluding that the picosecond treatment side is better simply because its number is smaller, or conversely accepting that the two treatments have equal effectiveness, goes beyond what the study actually found.

With only 16 participants, the study has limits in detecting small differences in effect or rare adverse reactions, and pain was compared only at the first treatment session. In particular, patients who had both freckles and lentigines together were excluded from the study, so this result cannot determine the treatment order for the mixed-pigment cases discussed earlier.

Common misconceptions

This article's treatment explanations by lesion type also referenced a consensus statement compiled by 10 experts who reviewed the literature and formed a shared opinion. The consensus statement is a summary of general treatment directions, while the study in the table above is a trial that directly compared the two treatments under specific conditions. We used all three types of material as evidence while distinguishing their nature, down to the clinic's patient case.

"Does the pico-toning group's lower score mean it's more effective?" You cannot draw that conclusion from the average values in the table alone. That's because, once the variation among study participants is taken into account, the researchers could not conclude that either treatment was superior. A small numeric difference should be distinguished from a proven advantage in effectiveness.

It's also easy to see a case that used multiple devices and think, "If I just get pico-toning, I'll see the same results." The case that addressed melasma, blemishes, and redness together was a record of combining pigment lasers, vascular treatment, and IPL. You cannot isolate the effect of pico-toning alone from the overall course of treatment.

In summary

When choosing a procedure, start by showing the specialist the brown spots you want removed. Depending on whether it's melasma, lentigo, or freckles, the approach may differ — whether to focus mainly on topical medication or add laser or IPL treatment. Rather than deciding on a device name in advance, focus on getting an explanation of which part of your face needs the treatment and why.

Frequently Asked Questions

For melasma, which is better — regular toning or pico-toning?

You cannot say that one is definitively better for all melasma patients. The comparative trial covered in this article did not demonstrate a proven difference in improvement between the two treatments, and patients with mixed freckles and lentigo were excluded from the study. When choosing a device, you also need to consider your own diagnosis and how you've responded to previous treatments.

Do I have to get IPL for freckles?

Both IPL and pigment lasers are options. The choice is made by considering not just the shape of the lesion but also skin sensitivity and any coexisting melasma, and in the freckle case described in the body of this article, toning was chosen because of the patient's skin condition.

If melasma and lentigo are mixed together, what gets treated first?

Overlapping melasma and skin irritation should be checked to decide the order of treatment. Clinic guidance also presents both approaches together: treating melasma first, and treating lentigines in areas without melasma first. Treatment plans can differ by area even on the same face.

If my skin looks blotchy and whitened after laser, is it okay to get more toning?

See a doctor about the whitened area before getting additional toning. Lightening of dark melasma and recovery of a hypopigmented area are different things, so you should not try to resolve this by simply increasing the number of sessions. At the consultation, let the doctor know which treatments you received and when, and when the blotching appeared.

Can I just follow the number of treatment sessions shown in a clinic's website case examples?

The number of sessions in a published case is that specific patient's treatment plan, not a universal recommended number. Even procedures with the same name may have involved different combined treatments or targeted different areas, so you should adjust the number of sessions and the interval based on how your own skin responds.
