PIH, sun spots, and melasma respond to a plan built around the pigment type, usually 3 to 6 sessions of laser toning, picosecond laser, or IPL with daily SPF 50.
Hyperpigmentation treatment fades uneven brown patches, using laser toning, picosecond laser, or IPL to break down excess melanin, matched to your pigment type and paired with topical care. At our Incheon Airport (Yeongjongdo) location, Dr. Sunbeen Kim grades your PIH, sun spots, or melasma and plans a realistic multi-session course with strict sun protection.

Hyperpigmentation treatment targets areas where the skin produces excess melanin, leaving brown or grey-brown patches. It covers a spectrum: post-inflammatory hyperpigmentation (PIH) that follows acne or irritation, sun spots and freckles from UV exposure, and melasma, a hormonally influenced pattern that behaves differently from the others. Because these types sit at different depths and respond differently, effective treatment starts with correctly identifying what you have rather than applying one blanket approach.
Treatment uses light-based energy, laser toning at low fluence, a picosecond or Q-switched laser, or intense pulsed light (IPL), to break down excess pigment so the body can clear it and tone evens out. Superficial sun spots often respond in a shorter series, while melasma and stubborn PIH need a gentler, longer course paired with a topical routine. Realistic, staged plans reduce the risk of temporary pigment rebound, which is more common in deeper skin tones.
At Reberry Clinic, pigment care is consultation-led. At our Incheon Airport (Yeongjongdo) location, Dr. Sunbeen Kim, Medical Director, first grades your pigment type and depth, then builds a tailored plan and explains it in English. Being minutes from ICN, the location suits travellers and transit patients seeking assessment near the airport.
Pigment-targeting devices rely on selective photothermolysis: light tuned to a wavelength that melanin absorbs strongly heats and fragments the excess pigment while sparing surrounding skin. A picosecond or Q-switched laser delivers ultra-short pulses that shatter melanin into fine particles the immune system clears, which suits defined sun spots and PIH; treated spots often darken briefly then flake over one to two weeks. Laser toning uses very low-energy, repeated passes to gently lift diffuse pigment, which is why it is favoured for melasma, a rebound-prone pattern that reacts badly to aggressive settings. IPL emits a broad, filtered band of light that treats scattered surface pigment across larger areas. Because melasma is hormonally influenced and can recur, it is managed with gentle repeated toning plus a topical routine and strict sun protection rather than pushed to clear fast. The clinic’s doctors match device, wavelength, and energy to your pigment type and skin tone, keeping settings conservative on deeper tones, and stage sessions so the skin is not over-stressed.

Doctors classify your pigment across the 3 main types (PIH, sun spots, melasma) and assess depth in a 15 to 20 minute consultation.
Laser toning, picosecond laser, or IPL is chosen for your pigment, with 1 to 3 tools sometimes combined across the plan.
Wavelength and energy are set for your Fitzpatrick skin type, kept low for melasma and darker tones to reduce rebound pigment.
Most plans run 3 to 6 sessions spaced about 2 to 4 weeks apart, since pigment fades gradually rather than in one visit.
Daily SPF 50 and a topical routine support each session, with occasional maintenance for rebound-prone patterns like melasma.
See representative outcomes from Reberry Clinic. Results build gradually and vary by individual; your plan is assessed at consultation.
Dr. Sunbeen Kim grades your pigment type and depth, then explains which modalities suit you and what to expect, in English.
After any numbing, a session usually takes about 15 to 30 minutes depending on the modality and area treated.
Plans run as a course of 3 to 6 sessions spaced about 2 to 4 weeks apart, so results build over weeks.
Sun spots often flake within about 2 weeks, while melasma fades more gradually as the managed course progresses.
Because pigment can recur, daily SPF 50, a topical routine, and occasional maintenance keep tone even long term.
Hyperpigmentation is excess melanin that leaves brown patches, spanning PIH, sun spots, and melasma. Treatment uses laser toning, picosecond laser, or IPL to break down pigment so the body clears it, matched to your type. A consultation confirms the pigment is benign before any dark spot removal is planned.
A doctor identifies your type by pattern, depth, and history: PIH follows acne or irritation, sun spots come from UV, and melasma forms symmetric hormonal patches. Getting this right matters because each responds differently. Your doctor grades your pigment at consultation, since the wrong approach, especially on melasma, can worsen it.
Melasma is usually managed with gentle, low-energy laser toning plus a topical routine and strict sun protection, rather than aggressive lasers that can trigger rebound. It is controlled over an ongoing course, not cleared in one visit. Your doctor explains a realistic plan during a laser treatment consultation.
A picosecond laser sends ultra-short pulses tuned to melanin, shattering pigment into fine particles your body clears over the following weeks. It suits defined sun spots and PIH, and studies show it causes less rebound pigment than older Q-switched settings. Treated spots typically darken briefly, then flake off over one to two weeks.
Most hyperpigmentation improves over 3 to 6 sessions spaced about 2 to 4 weeks apart, though melasma often needs more, ongoing maintenance. The exact number depends on your pigment type, depth, and response, which your doctor reviews between visits and adjusts rather than promising a fixed count at the start.
Most sessions are well tolerated, described as warm flashes or a brief snapping sensation, and numbing cream can be used for comfort. Laser toning is especially gentle. Sessions are short, usually 15 to 30 minutes. Your doctor explains what each modality feels like beforehand so you know what to expect.
Downtime is usually minimal. Picosecond-treated spots may darken and flake over 7 to 14 days, IPL can cause short-lived redness, and toning has little visible recovery. You can generally resume normal activity right away. Strict sun protection during healing is the main aftercare requirement to keep results even.
Visible evening of tone builds over the series rather than after one session. Sun spots often flake within about two weeks, while melasma and deeper PIH fade more gradually across the course. Your doctor reviews progress between sessions and adjusts the plan so improvement stays steady and natural-looking.
Cleared pigment can hold well, but hyperpigmentation, especially melasma, can recur, so it is managed rather than a one-time fix. Daily SPF 50, a topical routine, and occasional maintenance sessions help keep tone even. Your doctor builds long-term protection into your plan to limit recurrence over time.
It can be, but deeper tones carry a higher risk of temporary post-inflammatory pigment, so conservative settings and careful device choice are essential. Studies show picosecond settings cause less rebound than older lasers. Your doctor assesses your Fitzpatrick type and adjusts the plan so it stays safe and appropriate for you.
Keep skin gently cleansed, moisturised, and strictly sun-protected while pigment clears, and avoid picking so it fades evenly. Daily SPF 50 is essential. A supportive skin care routine helps the barrier recover. Your doctor gives specific aftercare based on the modality used in your session.
Yes, a topical routine and strict sun protection often make in-clinic sessions more efficient and support longer-lasting results. It complements, not replaces, treatment. Your doctor recommends products suited to your pigment as part of a broader glass facial skin approach for overall tone and clarity.
Most adults with PIH, sun spots, or stable melasma who can commit to sun protection are suitable for a structured plan. A consultation grades your pigment and confirms which modalities fit your skin. Any changing or irregular lesion needs medical review before cosmetic pigment treatment is considered.
Our Incheon Airport (Yeongjongdo) location, minutes from ICN, treats pigment with Dr. Sunbeen Kim, Medical Director, and English support, which suits transit and travelling patients. Reberry Clinic also has Gangnam and Myeongdong locations in central Seoul if those better fit your itinerary.
For a first session, 2 to 3 days is comfortable, allowing a consultation, treatment, and a short review. Because pigment plans run as a course, many international patients begin near the airport and continue across return visits. Our English-speaking team helps coordinate timing around your travel.
Yes, flying within a day or so is generally fine, since these treatments are non-invasive to minimally invasive. Treated spots may crust while you travel, so keep skin moisturised and strictly sun-protected. If you had a stronger laser setting, your doctor advises on aftercare to follow during your trip.
International patients can complete a pigment course across return visits, and the clinic offers remote check-ins in English between trips so the plan stays on track. You can continue supportive skin care with strict sun protection at home. Your treatment notes are kept on file for continuity.
