Hyperpigmentation has at least 3 main types (melasma, sun spots, post-inflammatory), so the right plan matches the modality to your pigment depth rather than using one device for everything.
Hyperpigmentation treatment in Myeongdong, Seoul depends on your pigment type: sun spots respond to pico laser or IPL, melasma needs gentle low-fluence toning plus topicals and strict sun protection, and post-inflammatory marks fade with a tailored plan. At our Myeongdong (Seoul) location, Dr. Seung Jae Baek diagnoses the type first, then builds a course.

Hyperpigmentation is any patch of skin that becomes darker than the surrounding area because pigment-producing cells overproduce melanin. It is not one condition but a family of them: sun spots and freckles from UV damage, melasma driven by hormones and heat, and post-inflammatory hyperpigmentation left behind by acne or injury. Because each type sits at a different depth and reacts differently to heat and light, the treatment plan varies significantly from person to person.
This is why a single device rarely fits every case. Surface sun spots often clear well with a picosecond laser or IPL, while melasma is heat-sensitive and can flare with aggressive settings, so it usually calls for low-fluence toning combined with topical agents and disciplined sun protection. Post-inflammatory marks need the underlying trigger controlled first. Getting the diagnosis right is the most important step, and it protects you from treatments that could darken pigment further.
At Reberry Clinic, hyperpigmentation care is consultation-led and delivered in English for international patients. Our Myeongdong (Seoul) location, at 5, Myeongdong 10-gil, Jung-gu, is about 5 minutes from Myeongdong Station, and Dr. Seung Jae Baek, Medical Director, identifies your pigment type before recommending pico laser, IPL, toning, or a combined plan.
Effective hyperpigmentation care works by matching the tool to where the pigment sits and how reactive it is. Epidermal pigment, like most sun spots and freckles, absorbs light readily, so a picosecond laser firing in trillionths of a second, or a broad-spectrum IPL, can fragment it efficiently with modest downtime. Dermal or mixed pigment, and especially melasma, is far more sensitive: too much heat drives inflammation that makes it worse, so it is managed with low-fluence 1064nm laser toning, topical tyrosinase inhibitors, and sometimes oral tranexamic acid under medical supervision. Across all types, photoprotection is the cornerstone, because ultraviolet light re-stimulates melanin and undoes progress. A doctor-led plan therefore sequences modalities carefully, often over a series of sessions, and combines in-clinic treatment with daily home skincare and sunscreen. This is why your plan is set only after your pigment type is diagnosed, not from a fixed menu.

Doctors distinguish the 3 main types (melasma, sun spots, post-inflammatory) and grade your Fitzpatrick skin type, which drives every later choice.
Surface pigment may suit pico laser or IPL, while melasma usually needs low-fluence toning, so the tool is chosen for pigment depth; a typical toning course runs 6 to 10 sessions.
Tyrosinase inhibitors and, in select melasma cases, oral tranexamic acid are added under medical review to work alongside in-clinic sessions.
Most hyperpigmentation improves over a course of several sessions spaced weeks apart, not in a single visit, so the plan is mapped as a series — usually 4 to 8 sessions over 2 to 3 months.
Daily broad-spectrum sunscreen is essential, since 1 unprotected week of sun can undo weeks of progress and restart pigment.

At our Myeongdong (Seoul) location, Dr. Seung Jae Baek diagnoses your pigment type and skin type, then explains which modalities fit, in English.
A first session usually takes about 20 to 40 minutes depending on the modality, with cooling and eyewear used during any laser or IPL.
Hyperpigmentation runs as a course, so treatment is mapped across several sessions spaced weeks apart rather than a single visit.
Surface pigment often fades within 1 to 3 sessions, while melasma and deeper marks improve more gradually with maintenance and sun care.
Because pigment is UV-driven and melasma recurs, daily sunscreen and periodic maintenance keep results stable long term.



Hyperpigmentation is treated by first diagnosing the pigment type, then matching the modality: pico laser or IPL for sun spots, low-fluence toning plus topicals for melasma, and trigger control for post-inflammatory marks. At our Myeongdong location, Dr. Seung Jae Baek builds the plan. See our dark spot removal page.
Our Myeongdong (Seoul) location is at 5, Myeongdong 10-gil, Jung-gu, about 5 minutes from Myeongdong Station, where Dr. Seung Jae Baek diagnoses and treats hyperpigmentation. It is convenient for international patients in central Seoul, with English-speaking staff to guide your consultation and plan around your schedule.
Because hyperpigmentation has several types that sit at different depths and react differently to heat. Sun spots respond to pico laser or IPL, while melasma is heat-sensitive and can worsen with aggressive settings. A correct diagnosis prevents treatments that darken pigment, which is why the plan is set only after assessment, not from a fixed menu.
Melasma is usually managed with gentle low-fluence 1064nm laser toning, topical tyrosinase inhibitors, sometimes oral tranexamic acid under medical review, and strict sun protection. Aggressive lasers or IPL can flare it, so restraint matters. It is chronic and prone to recurrence, so it is controlled over time rather than fixed in one course.
Yes, a picosecond laser is often effective for stubborn or deeper pigment because it fires ultra-short pulses that fragment melanin selectively with modest downtime. Whether it fits depends on your pigment type and depth, confirmed at consultation. You can read more about our approach on the dark spot removal page.
Most hyperpigmentation improves over a course of several sessions spaced weeks apart, not a single visit. Surface sun spots may clear in 1 to 3 sessions, while melasma and deeper marks need more sessions plus maintenance. Your doctor reviews progress between visits and adjusts the plan so it stays effective for your pigment type.
Comfort varies by modality: laser toning and IPL feel like mild warmth or a light snap, while pico laser gives a quick tingling that numbing cream can ease. Sessions are generally well tolerated and last about 20 to 40 minutes. Your clinician adjusts settings and cooling so treatment stays comfortable for your skin.
Downtime depends on the tool. Pico laser and toning usually leave only brief redness for hours to a day, while IPL forms fine micro-crusts that flake over about 7 to 14 days. Most patients return to daily life quickly, using gentle skincare and strict sunscreen. Your doctor explains expected recovery for each modality first.
Surface sun spots often fade visibly within 1 to 3 sessions, while melasma and post-inflammatory marks improve more gradually across the course. Because pigment sits at different depths, timelines vary. Your doctor tracks progress between sessions so the plan and spacing stay matched to how your specific pigment is responding.
Results can hold well, but pigment is UV-driven and melasma tends to recur, so it is managed and controlled rather than removed forever. Daily broad-spectrum sunscreen and periodic maintenance sessions keep skin clearer over time. A supportive skin care routine helps protect your progress between visits.
Yes, plans often combine in-clinic sessions with topicals and, for some pigment, a separate laser treatment. Your doctor sequences modalities so the skin is not over-stressed, for example treating surface spots first and melasma more gently. Combining tools thoughtfully addresses several pigment types, always under an individualised plan.
Yes, when settings are conservative and matched to your Fitzpatrick skin type, because deeper tones are more prone to post-inflammatory pigmentation if over-treated. A doctor grades your skin and may favour gentler toning. This careful, skin-type-aware approach is central to how we plan hyperpigmentation care for international patients.
Sunscreen is essential because ultraviolet light re-stimulates melanin and can undo weeks of progress in days, especially for melasma. Daily broad-spectrum SPF protects your investment and improves how well every session works. Your doctor recommends a routine, and a supportive skin care plan helps maintain even tone.
Most adults with sun spots, freckles, melasma, or post-inflammatory marks are suitable for a tailored plan once the pigment type is diagnosed. A consultation grades your skin and confirms which modality is safest. Undiagnosed or changing lesions are assessed first, and your doctor will explain the safest path for your specific pigment.
For a first session, 2 to 3 days in Seoul is comfortable, allowing a consultation, treatment, and time for initial redness to settle. Because hyperpigmentation runs as a course, many international patients begin here and continue across return visits, coordinating spacing with our English-speaking team around their travel.
International patients can complete a hyperpigmentation course over one or more Seoul visits, and our English-speaking team offers remote check-ins between trips so the plan stays on track. You can continue prescribed topicals and supportive skin care at home, with your treatment notes kept on file for continuity.
