Quick Answer

What is PIH Treatment at Kind Global Clinic?

PIH Treatment at Kind Global Clinic Myeongdong is a conservative protocol for Post-Inflammatory Hyperpigmentation that combines topical brightening agents (niacinamide, azelaic acid, vitamin C), low-fluence Q-switched Nd:YAG laser toning at 1064 nm (2 to 3 mJ/cm²) and strict SPF 50+ photoprotection — designed to fade post-acne, post-procedure and post-traumatic darkening in Fitzpatrick III to V skin over a 3 to 12 month resolution window.

Post-Inflammatory Hyperpigmentation (PIH) is the darkening that follows any inflammatory event in the skin — acne lesions, ingrown hair, eczema flare, allergic dermatitis, cuts, burns or procedures (laser, peel, microneedling) — and is most pronounced in Fitzpatrick III to V skin because higher baseline melanocyte activity responds more vigorously to inflammatory cytokines. Unlike melasma, PIH typically follows a discrete inflammatory trigger and tends to resolve over months once inflammation is settled and ultraviolet exposure is controlled.

Kind Global Myeongdong follows a conservative, prevention-first protocol because aggressive treatment can paradoxically worsen PIH in darker skin types. Pillar one is calming the underlying inflammation: treating active acne, eczema or dermatitis before pigment work begins. Pillar two is topical brightening with niacinamide 4 to 5 percent (melanosome transfer inhibition), azelaic acid 10 to 20 percent (tyrosinase inhibition and anti-inflammatory) and stabilized vitamin C 10 to 15 percent (antioxidant and melanogenesis modulation). Tranexamic acid topical or oral may be added for resistant PIH. Pillar three is low-fluence Q-switched Nd:YAG laser toning at 1064 nm (2 to 3 mJ/cm², large-spot, every 2 to 3 weeks) which fragments dermal pigment without ablative injury. Pillar four is strict SPF 50+ broad-spectrum sunscreen and active avoidance of triggers.

Both co-directors personally manage every PIH plan — no nurse delegation. Fitzpatrick mapping, trigger event documentation (acne, procedure, trauma), prior treatment response, baseline photography and zone map are charted at the consultation. Compared with a chronic-relapsing <a href="/melasma-treatment-myeongdong-seoul-korea/">Multi-modal Melasma Treatment</a> (oral TXA + diffuse pattern) or a discrete-lesion <a href="/sunspot-removal-myeongdong-seoul-korea/">Sunspot Laser Removal</a> (single-shot lentigo ablation), the PIH protocol is indicated for inflammation-driven darkening that typically resolves naturally given enough time, topical support and photoprotection.

Who is this for?

Who is PIH Treatment for?

For

  • Patients with post-acne darkening at the site of previously inflamed lesions, predominantly on cheeks, jawline and chin
  • Patients with post-procedure PIH following laser, microneedling, RF or chemical peel — most common in Fitzpatrick IV-V skin
  • Patients with post-traumatic darkening at the site of cuts, burns, ingrown hair or insect bite reactions
  • Patients with Fitzpatrick III to V skin where conservative low-fluence protocols are preferred over aggressive resurfacing
  • Patients seeking active management of PIH alongside ongoing acne treatment or other inflammatory dermatosis control

Not for

  • Active acne flare, eczema flare, dermatitis or any uncontrolled inflammatory dermatosis — underlying inflammation must be settled before pigment treatment
  • Suspicion of melanoma, atypical mole or any pigmented lesion with irregular borders, color variation or recent change — evaluation required first
  • Pregnancy and breastfeeding — retinoic acid, hydroquinone and oral tranexamic acid are contraindicated; conservative topicals such as niacinamide and azelaic may continue under physician guidance
  • Personal or family history of thromboembolism or active anticoagulant therapy if oral tranexamic acid is being considered
  • Recent isotretinoin (within 6 months), recent ablative laser (within 4 weeks) or active herpes labialis outbreak in treatment zone
How it works

How PIH Treatment works at Kind Global Clinic — your visit, step by step

  1. 1

    Co-Director Consultation + Trigger Documentation 15-20 min

    Dr. Lee Wonjin or Dr. Lee Kangin reviews the inflammatory trigger event (acne, procedure, trauma, dermatitis), time since onset, prior topical and laser response, and any current dermatologic conditions that need to be controlled before pigment work. Fitzpatrick type, PIH pattern, zone map (cheeks, jawline, chin, body), photo baseline and any history of recurrent PIH are recorded. The co-director confirms that underlying inflammation is settled before recommending laser toning.

  2. 2

    Topical Brightening Regimen Construction 10-15 min

    Based on Fitzpatrick type and PIH pattern, the co-director constructs a tiered topical regimen: niacinamide 4-5 percent morning and evening, azelaic acid 10-20 percent once or twice daily (titrating up to tolerance), stabilized vitamin C 10-15 percent in the morning. Topical tranexamic acid or oral tranexamic acid may be added for resistant or extensive PIH after coagulation screening. Brand, batch and patient counseling are recorded. SPF 50+ broad-spectrum with iron oxide is mandatory.

  3. 3

    First Low-Fluence Laser Toning Session 20-35 min

    Low-fluence Q-switched Nd:YAG laser toning at 1064 nm is delivered at 2 to 3 mJ/cm² with a large 6 to 8 mm spot in two to three full-face or zone passes. Endpoint is mild erythema only, no purpura or whitening — the conservative fluence is deliberate for Fitzpatrick IV-V skin to avoid paradoxical PIH worsening. Device serial, fluence, spot size, number of passes and total energy are charted. Total in-clinic time runs 20 to 35 minutes including post-care.

  4. 4

    3-Month Cycle Plan + Aftercare Brief 10-15 min

    The treating co-director walks you through the 3-month initial cycle: laser toning every 2 to 3 weeks (4 to 8 sessions total), topical regimen daily, mandatory SPF 50+, monthly photo comparison. LINE / WhatsApp / WeChat contact provided. Follow-up reviews at week 4, week 8 and week 12 are scheduled, with extended cycle planning at month 3 if needed. The co-director may titrate laser fluence, adjust topical strength or pause and recalibrate if any sign of PIH worsening is detected.

What to expect

PIH Treatment — week-by-week expectations across the protocol

Day 0First laser toning session delivered; mild post-laser erythema 30-60 minutes; topical regimen started; baseline photography
Week 2-4Sessions 2-3 of low-fluence toning; topical regimen settling in; mild dryness or stinging from azelaic during adaptation typically normalizes
Week 6-8First visible lightening of PIH patches; remaining patches still pigmented but less saturated; photo comparison shows clear contrast
Week 12Initial 3-month reassessment: many patches significantly lightened or resolved; co-director decides whether to extend cycle, taper topicals or transition to maintenance
Month 6Most PIH resolved given strict SPF compliance; remaining residual darkness in Fitzpatrick V skin may continue to fade naturally with maintenance
Month 9-12Final resolution for most patients; recurrence is driven by ongoing inflammatory events (new acne, new procedures) — prevention becomes the primary maintenance pillar

Selection depends on the underlying trigger (inflammation-driven PIH vs chronic relapsing melasma vs discrete solar lentigines vs diffuse epidermal pigment). Co-director consultation with Fitzpatrick mapping, trigger documentation and zone analysis determines the right protocol. Many patients have overlapping pigmentation patterns (PIH after acne plus mild melasma) and benefit from layered sequencing across cycles.

              Evidence

              Evidence base for conservative PIH protocol

              1. Topical niacinamide and azelaic acid for post-inflammatory hyperpigmentation: randomized comparative study
                Journal of Cosmetic Dermatology (2019) — DOI: 10.1111/jocd.12888

                Randomized comparative study of topical niacinamide 4 percent and azelaic acid 20 percent for post-inflammatory hyperpigmentation in Fitzpatrick III-V skin. Documented significant reduction in pigment index across both arms with similar tolerability, supporting the topical brightening pillar of the conservative protocol used at Kind Global Myeongdong.

              2. Low-fluence Q-switched 1064 nm Nd:YAG laser toning for post-inflammatory hyperpigmentation in Asian skin
                Dermatologic Surgery (2020) — DOI: 10.1097/DSS.0000000000002265

                Prospective Asian Fitzpatrick III-V cohort treated with low-fluence Q-switched 1064 nm Nd:YAG laser toning at 2-3 mJ/cm² every 2 to 3 weeks for post-inflammatory hyperpigmentation. Demonstrated significant pigment fade across an 8 to 16 week cycle with predominantly mild transient erythema, supporting the laser pillar of the conservative protocol at Kind Global Myeongdong.

              3. Photoprotection with iron-oxide-containing broad-spectrum sunscreen for hyperpigmentation prevention
                Journal of the American Academy of Dermatology (2021) — DOI: 10.1016/j.jaad.2020.10.080

                Prospective study of iron-oxide-containing broad-spectrum SPF 50+ sunscreen versus SPF-only formulations for hyperpigmentation prevention in patients with PIH and melasma. Demonstrated visible-light protection reduces pigment rebound rate in Fitzpatrick IV-V skin, supporting the photoprotection pillar of the Kind Global protocol.

              Frequently asked

              PIH Treatment at Kind Global Clinic Myeongdong — frequently asked

              Who manages PIH treatment at Kind Global Clinic Myeongdong?
              PIH Treatment at Kind Global Clinic Myeongdong is managed personally by 2 licensed Korean co-directors -- Dr. Lee Wonjin (KR Medical License 143124, Daegu Catholic University College of Medicine, 2022) or Dr. Lee Kangin (KR Medical License 141247) -- with 15 to 20 minute consultations, zero nurse delegation, and same-physician continuity across the 3-month initial cycle and any extended maintenance. Trigger event (acne, procedure, trauma, dermatitis), time since onset, prior topical and laser response, current dermatologic conditions, Fitzpatrick mapping, PIH pattern and zone map are recorded on each patient's chart at the consultation. The patient may request either co-director when booking; if preference is unavailable, concierge will offer the alternative or reschedule at no charge. The co-director who consults you is the same physician who delivers laser toning, titrates topical regimens, and reviews you at week 4, week 8 and week 12 milestones. There is no junior-doctor rotation or third-party nurse application. This matters for PIH because conservative fluence selection in Fitzpatrick IV-V skin requires real-time assessment of erythema response by the physician who has assessed your baseline pigment and trigger profile.
              How long do PIH Treatment results last at Kind Global Clinic Myeongdong?
              PIH typically resolves over a 3 to 12 month cycle when the conservative four-pillar protocol is followed at Kind Global Clinic Myeongdong, and once resolved the original patches do not return. However PIH is trigger-driven, so any new inflammatory event (new acne lesion, new procedure, new dermatitis flare) can produce fresh PIH at the new site — ongoing prevention is the primary maintenance pillar. A randomized study (Journal of Cosmetic Dermatology 2019, DOI: 10.1111/jocd.12888) documented significant pigment fade across topical niacinamide and azelaic acid arms in Fitzpatrick III-V skin. A laser cohort study (Dermatologic Surgery 2020, DOI: 10.1097/DSS.0000000000002265) demonstrated significant fade across an 8 to 16 week low-fluence Q-switched 1064 nm Nd:YAG toning cycle. Long-term maintenance includes daily SPF 50+ with iron oxide, baseline niacinamide twice daily for PIH-prone patients, and quick management of any new inflammatory triggers. Layered <a href="/cosmelan-peel-myeongdong-seoul-korea/">Cosmelan Peel</a> or <a href="/rejuran-myeongdong-seoul-korea/">Rejuran</a> can address adjacent skin-quality co-issues during the maintenance window.
              How much does PIH Treatment cost in Myeongdong Seoul 2026?
              PIH conservative treatment at Kind Global Clinic Myeongdong is priced per pillar with a recommended full-cycle bundle. Korea pricing for the 12-week Full Conservative Bundle runs USD 580 to 600 at current exchange — 60 to 75 percent less than United States pricing for an equivalent dermatologist-led PIH program (USD 2,000 to 2,800 in the US for comparable consultation plus low-fluence toning plus topical bundle) and 40 to 55 percent less than Japan. Standard event pricing: PIH Initial Consultation KRW 100,000; Low-Fluence Laser Toning per session KRW 120,000; PIH 4-Session Cycle KRW 449,000; PIH 8-Session Cycle KRW 790,000; PIH Topical Brightening Kit 3-month supply KRW 198,000; Full Conservative Bundle KRW 790,000. Same KRW price applies to international and Korean patients with no surcharge. Full pricing is published in the table on this page and confirmed at consultation. Korean medical-aesthetic pigmentation pricing is one of the drivers of the 600,000+ medical tourists attracted to Korea in 2023 per KHIDI data.
              PIH Treatment vs multi-modal Melasma Treatment — how do I choose?
              The choice depends on whether pigment is trigger-driven discrete darkening (PIH) or chronic relapsing diffuse pattern (melasma). <table><thead><tr><th>Criteria</th><th>PIH Conservative</th><th>Multi-modal Melasma</th></tr></thead><tbody><tr><td>Trigger</td><td>Post-acne, post-procedure, post-traumatic</td><td>UV, hormonal, heat, idiopathic</td></tr><tr><td>Pattern</td><td>Discrete darkening at prior inflammation site</td><td>Symmetric diffuse facial patches</td></tr><tr><td>Natural course</td><td>Typically resolves 3-12 months</td><td>Chronic relapsing, lifelong management</td></tr><tr><td>Oral TXA</td><td>Optional for resistant cases</td><td>Standard pillar</td></tr><tr><td>Sessions</td><td>4-8 toning + ongoing topical</td><td>5-10 toning + ongoing topical + oral</td></tr><tr><td>Downtime</td><td>0-1 day per session, minimal overall</td><td>0-1 day per session, minimal overall</td></tr></tbody></table> PIH Treatment is well suited for patients with darkening following acne, procedures or trauma. <a href="/melasma-treatment-myeongdong-seoul-korea/">Multi-modal Melasma Treatment</a> is well suited for patients with chronic diffuse facial patches, especially with hormonal trigger or mixed-type pattern. Patients with both conditions (common after years of acne with secondary melasma) often layer the PIH conservative protocol with a melasma cycle.
              PIH Treatment vs Sunspot Laser Removal — what's the difference?
              PIH is inflammation-driven darkening that fades over months with conservative treatment; sunspots are discrete UV-driven lentigines that require single-shot laser ablation. <table><thead><tr><th>Criteria</th><th>PIH Conservative</th><th>Sunspot Laser</th></tr></thead><tbody><tr><td>Trigger</td><td>Inflammation (acne, procedure, trauma)</td><td>Chronic UV exposure</td></tr><tr><td>Border</td><td>Soft-bordered patches at prior lesion site</td><td>Sharply bordered discrete spots</td></tr><tr><td>Natural course</td><td>Typically resolves 3-12 months</td><td>Permanent unless treated</td></tr><tr><td>Sessions</td><td>4-8 low-fluence toning + topical</td><td>1 single-shot session typically sufficient</td></tr><tr><td>Downtime</td><td>0-1 day per session, minimal overall</td><td>Tiny scab 7-14 days per spot</td></tr><tr><td>Indicated for</td><td>Post-acne or post-procedure darkening</td><td>Discrete solar lentigines</td></tr></tbody></table> PIH Treatment is well suited for patients with soft-bordered darkening following an inflammatory event. <a href="/sunspot-removal-myeongdong-seoul-korea/">Sunspot Laser Removal</a> is well suited for patients with discrete, sharply-bordered solar lentigines that have been stable for at least 12 months. Both can be layered when a patient has both presentations on the same face.
              Korean PIH Treatment vs Western PIH treatment — what's the difference?
              Korean dermatology has long emphasized conservative low-fluence protocols for PIH because Fitzpatrick III to V skin predominates in the population and aggressive treatment risks paradoxical worsening. The conservative four-pillar approach is similar across Korea, the United States and Europe; the difference is cost, application standard and language access. <table><thead><tr><th>Criteria</th><th>Korea (Kind Global)</th><th>United States / Western</th></tr></thead><tbody><tr><td>Full conservative bundle cost</td><td>USD 580-600</td><td>USD 2,000-2,800</td></tr><tr><td>Laser fluence philosophy</td><td>Conservative low-fluence standard for Fitz III-V</td><td>Variable; some clinics still use higher fluences</td></tr><tr><td>Iron-oxide SPF</td><td>Standard recommendation</td><td>Less commonly emphasized</td></tr><tr><td>Topical brightening tiers</td><td>Niacinamide + azelaic + Vit C standard</td><td>Hydroquinone-first in many clinics</td></tr><tr><td>Application</td><td>Licensed Korean physician (Medical Service Act)</td><td>Physician or extender depending on state</td></tr><tr><td>Follow-up</td><td>Week 4, 8 and 12 with co-director</td><td>Variable</td></tr></tbody></table> Korean physician-led PIH protocols attracted a meaningful share of the 600,000+ medical tourists in 2023 per KHIDI data — the conservative low-fluence approach, value-equivalent cost, mandatory Korean-physician-only application under the Medical Service Act, and structured follow-up cadence drive demand for Fitzpatrick III-V patients.
              How painful is PIH Treatment at Kind Global?
              Most patients rate discomfort across the conservative PIH protocol at 1 to 3 out of 10 during laser toning sessions and minimal at all other times. Low-fluence Q-switched 1064 nm Nd:YAG laser toning at 2 to 3 mJ/cm² produces a brief warm sensation that the co-director monitors throughout each 2 to 3 pass session; the toning endpoint is mild erythema only, with no purpura or whitening. Topical regimens occasionally produce mild stinging or dryness for the first 1 to 2 weeks as the skin adapts, especially with azelaic acid at higher concentrations; titrating azelaic from once daily to twice daily over 1 to 2 weeks usually solves this. Vitamin C may produce mild tingling on application that resolves quickly. No injectable anesthesia is needed for low-fluence toning; cooling air is delivered continuously during the laser pass. After the session, a soothing mask and SPF 50+ broad-spectrum sunscreen are applied in clinic before discharge. The conservative fluence is deliberate — going higher in Fitzpatrick IV-V skin risks paradoxical PIH worsening.
              What are the side effects and risks of conservative PIH Treatment?
              Conservative PIH Treatment shares the safety profile of physician-supervised low-fluence layered pigment protocols. Common temporary effects across the four pillars: mild post-laser erythema 30 to 60 minutes per session, mild dryness or stinging from azelaic during topical adaptation, mild tingling from vitamin C on application, and occasional initial flaking from topicals during the first 1 to 2 weeks. Rare effects include paradoxical PIH worsening if fluence is too aggressive (well under 5 percent in published cohorts when conservative low-fluence settings are used per the Dermatologic Surgery 2020 study DOI: 10.1097/DSS.0000000000002265), contact dermatitis to a topical component, and herpes labialis reactivation. The serious adverse event of scarring is rare with low-fluence toning. Contraindications include active acne flare or dermatitis (must be settled first), pregnancy and breastfeeding for retinoid- or hydroquinone-containing options, recent isotretinoin within 6 months, recent ablative laser within 4 weeks, and known retinoid or hydroquinone hypersensitivity. The conservative low-fluence approach is deliberate for Fitzpatrick III-V skin because aggressive treatment can paradoxically worsen PIH.
              Are the laser devices and topical kits used at Kind Global Myeongdong original manufacturer products?
              Yes — Kind Global Clinic Myeongdong uses only manufacturer-original Q-switched Nd:YAG laser systems for PIH toning, never refurbished, never grey-market, and never repackaged. Each in-clinic laser session is recorded with device brand, serial, fluence (mJ/cm²), spot size, number of passes and total energy on the patient chart. Topical brightening kits (niacinamide, azelaic acid, vitamin C) are from established medical-aesthetic suppliers with brand label, batch number, manufacturing date and expiry visible. Topical or oral tranexamic acid is dispensed from a licensed Korean pharmacy with prescription documentation where indicated. On request, we will show you the laser system serial label and the unopened sealed topical kits so you can verify the brand and batch. This transparency policy applies equally to international and Korean patients, with no exceptions. The KFDA monitors aesthetic laser systems and cosmeceutical products for compliance; verifying device brand and batch is a direct way for patients to confirm authenticity.
              How many sessions are needed and when do PIH results appear?
              The standard conservative PIH protocol runs across a 3-month initial cycle (4 to 8 low-fluence toning sessions every 2 to 3 weeks) plus ongoing topical brightening and SPF 50+ photoprotection. First visible lightening of PIH patches typically emerges at week 6 to 8 of the cycle. The week 12 reassessment evaluates whether to extend the cycle, taper topicals or transition to maintenance. Most patches significantly lighten or resolve across the 3 to 12 month natural course of PIH given strict SPF compliance and topical adherence. Extensive or resistant PIH (often Fitzpatrick V with multiple inflammatory events) may need the 8-session extended cycle and longer topical maintenance. The total resolution timeline varies because PIH is partly determined by the depth of original pigment deposition — superficial epidermal PIH resolves faster than dermal-component PIH. Skipping daily SPF or developing new inflammatory events is the primary cause of suboptimal response. New acne lesions that develop during the cycle should be treated quickly to prevent fresh PIH at new sites.
              Can I start PIH Treatment as a same-day procedure when visiting Seoul?
              Yes — the first conservative PIH visit is routinely completed on the same day for international visitors to Kind Global Clinic Myeongdong, but ongoing pillars require either return visits or courier-shipped topical kits. Plan 60 to 90 minutes for the first visit: 15-20 minutes co-director consultation with trigger documentation and Fitzpatrick mapping; 10-15 minutes topical regimen construction and prescription review; 20-35 minutes first low-fluence laser toning session; 10-15 minutes home regimen brief and follow-up scheduling. Flying home the same day is acceptable after a low-fluence toning session because there is no purpura and only mild erythema for 30 to 60 minutes. Most international patients complete one to two in-clinic toning sessions during their Seoul visit and continue the protocol from home with courier-shipped topical kits and physician-coordinated local pharmacy fills where possible. We recommend SPF 50+ broad-spectrum daily, iron oxide sunscreen for visible-light protection, and avoiding sauna, jjimjilbang and hot yoga for 48 hours after each laser session. If you message us via WhatsApp Business, LINE Official or WeChat before your flight from Tokyo, Bangkok, Madrid, Taipei or Shanghai, we can pre-confirm your protocol and check-in time.
              Do you have English-speaking staff and translators for PIH Treatment consultation?
              Yes — both Kind Global Clinic co-directors conduct PIH consultations directly in Korean and English at our Myeongdong 6F location, and HEIM Global concierge interpreters cover other languages. For Japanese, Spanish, Simplified Chinese and Traditional Chinese, HEIM Global concierge provides professional medical interpretation at no additional fee — message via LINE Official, WhatsApp Business, WeChat Official or Telegram before your visit to schedule. Pre-application interpretation covers trigger history (acne, procedure, trauma, dermatitis), Fitzpatrick mapping, prior treatment response, retinoid and hydroquinone allergy review, anticoagulant disclosure if oral tranexamic acid is being considered, and pillar selection rationale; post-application interpretation covers the 12-week schedule, SPF 50+ and iron oxide guidance, topical titration and trigger-avoidance counseling, and follow-up milestones at week 4, 8 and 12. Written treatment summaries with brand, batch number, fluence settings and aftercare instructions are provided in your language. For Arabic, Vietnamese, Thai or Russian, contact us via email at info.kindglobal@gmail.com to request a contracted interpreter for your visit window. KHIDI 2025 Medical Tourism Survey notes language accessibility is a top-3 factor for international patients selecting Korean clinics.
              Can I combine PIH Treatment with Rejuran, Mesotherapy or other skin-quality protocols in the same cycle?
              Yes — the conservative PIH protocol is frequently layered with adjacent skin-quality protocols at Kind Global Clinic Myeongdong, but sequencing matters and ongoing inflammation must be controlled first. Injectable skin boosters such as <a href="/rejuran-myeongdong-seoul-korea/">Rejuran</a> or <a href="/mesotherapy-myeongdong-seoul-korea/">Mesotherapy</a> are usually spaced 1 to 2 weeks from laser toning sessions to give the epidermal barrier recovery time and to avoid injection over actively inflamed PIH zones. <a href="/density-myeongdong-seoul-korea/">Density</a> RF tightening can run alongside the PIH cycle but is typically scheduled on alternating weeks from laser toning. HIFU lifting such as <a href="/ultherapy-prime-myeongdong-seoul-korea/">Ultherapy Prime</a> is delivered at separate visits, typically after the 12-week initial cycle when pigmentation is settling. A diffuse depigmentation protocol such as <a href="/cosmelan-peel-myeongdong-seoul-korea/">Cosmelan Peel</a> may be layered for patients with co-existing epidermal melasma. <a href="/carbon-laser-peel-myeongdong-seoul-korea/">Carbon laser peel</a> for surface refinement is usually scheduled after PIH is controlled because surface lasers can transiently worsen active PIH. Your co-director sequences the layered plan based on response and tolerance.
              Is PIH Treatment safe for very dark Fitzpatrick V skin or sensitive skin?
              Yes — the conservative low-fluence protocol is specifically designed for Fitzpatrick III to V skin, with explicit care to avoid paradoxical PIH worsening that can occur when aggressive fluences are used in darker skin types. Laser toning fluence is set at 2 to 3 mJ/cm² (low end) with a large 6 to 8 mm spot and endpoint of mild erythema only, no purpura or whitening. Topical brightening starts with niacinamide (extremely well tolerated across all Fitzpatrick types) and titrates up to azelaic acid and vitamin C over weeks. Hydroquinone is reserved for resistant cases with careful titration and limited duration. The Dermatologic Surgery 2020 study (DOI: 10.1097/DSS.0000000000002265) documented a low paradoxical PIH rate at low-fluence 1064 nm settings in Asian Fitzpatrick III-V skin. Patients with very sensitive skin or active rosacea are often started with topicals only for 4 to 6 weeks before introducing laser toning, to confirm barrier tolerance. The co-director performs careful zone mapping at consultation and titrates each pillar based on individual response.
              How do I prepare for my PIH Treatment appointment at Kind Global?
              Before your PIH consultation, gather a history of when the darkening first appeared, the inflammatory trigger that preceded it (acne, procedure, trauma, dermatitis), prior treatments tried (topical, oral, laser, peel), current dermatologic conditions still active, occupation and outdoor exposure pattern, and your current photoprotection routine. Photograph the affected zones in good lighting and bring the photos to the consultation. Pause topical retinol, vitamin C, AHA, BHA and hydroquinone for 5 days before the first laser toning session to avoid stacked irritation. Avoid sun exposure and self-tanner for 2 weeks; treat any active acne breakout or cold sore before booking. Disclose pregnancy, breastfeeding, recent isotretinoin within 6 months, recent ablative laser within 4 weeks, current photosensitizing medication and anticoagulant medication on the consultation form. Hydrate well and eat a normal meal — the protocol is not performed under sedation. Bring a wide-brim hat and SPF 50+ with iron oxide for the journey to and from the clinic. Arrive 15 minutes early; if you messaged us in advance via WhatsApp or LINE, paperwork is pre-completed. After each laser toning session: no makeup 6 hours, no sauna or jjimjilbang for 48 hours, SPF 50+ broad-spectrum daily, soothing bland skincare, niacinamide twice daily from day 1, gradual introduction of azelaic and vitamin C as planned. Follow-up reviews at week 4, 8 and 12 are scheduled before you leave the clinic.
