Melasma, Pores, and Acne Scars: What Order to Treat Them?

TL;DR: When melasma, enlarged pores, and acne scars show up together, the safer sequence is: calm any active inflammation first, stabilize the skin barrier, address pigmentation, rebuild scars and pores, and only then work on firmness. Treating the most visible concern first often backfires, because inflamed skin tends to produce fresh pigment, sending the whole plan back to the start. Sensitive skin is rarely a reason to rule out laser treatment outright; it just means more questions get asked before anything is scheduled.

I’m Kim Kyungsoo, director at UH CELL’s Seocho clinic, and one of the most common questions I hear in consultation is some version of “I have melasma, my pores are wide, and I still have marks from old acne, so what do I start with?” The short answer is that priority is set by what the skin is doing right now, not by what looks worst in the mirror. Those are rarely the same thing. Layering a pigment-focused treatment onto skin that’s still inflamed can push that irritation toward making more pigment rather than less.

Why the Order Matters More Than the Device Name

The sequence I use in consultation, and the one recurring through the clinical literature on this, runs in five stages:

1. Active inflammation first. If new acne lesions are still forming or something is visibly swollen and red, that’s where treatment starts. A 2021 clinical trial protocol published by Galderma frames management of post-acne hyperpigmentation as beginning with treatment of the underlying inflammatory condition. Pigment is a downstream product of inflammation, so while the cause keeps cycling, new pigment can form faster than existing pigment fades.
2. Barrier and sensitivity stabilization. Flaking, stinging, or frequent flushing signals a barrier that needs time before it can absorb more energy without a longer recovery.
3. Pigmentation. Melasma, sun spots, and brown marks belong here. The season and how consistently sun protection can continue after returning home both weigh heavily on timing.
4. Scar and pore remodeling. Depressed scars and enlarged pores are a dermal rebuilding job, and this is often where the most visible recovery reaction shows up.
5. Firmness. Sagging and contour change get evaluated once the stages above are settled.

The reasoning behind this order comes down to what each stage demands from the skin. Pigment treatment needs energy calibrated so it doesn’t provoke the melanocytes further, while resurfacing treatment deliberately creates controlled micro-injury to trigger a rebuilding response. Stacking both goals onto the same face on the same day makes it hard to tell which reaction came from which treatment.

What We Look at First, by Concern Combination

Concern combination	What we check first	Candidate categories (Seocho menu)	Combination to avoid	Basis
Melasma + pores	Depth of the melasma and recent sun exposure; whether the pores are oil-driven or related to lost elasticity	Low-energy toning for pigment, separate handling for pores	Strong resurfacing and pigment treatment scheduled the same week	The International Society of Dermatology’s 2024 melasma guideline treats photoprotection as foundational to any treatment plan
Acne marks + pigmentation	Whether new lesions are still active; whether the marks are red or brown	Settle active inflammation first, then pigment, with depressed scars addressed afterward	Fractional-type treatment while active acne is still present	The principle that post-acne pigment management starts with treating the underlying inflammation
Flushing + pigmentation	Whether the flushing is a temporary reaction or persistent vascular dilation, plus recent irritation history	Secure a barrier-stabilization period first, then a low-energy pigment approach	Repeated test spots stacked before the skin has recovered, overlapping redness	Research linking post-treatment erythema to pigmentation outcomes
Scarring + firmness	Scar shape (ice-pick, boxcar, rolling) and which layer is driving the sagging	Scar remodeling first, firmness devices only after recovery	Adding high-intensity heat-based treatment onto skin still recovering	Classification showing that atrophic scars respond differently depending on their shape

Where the Bar Gets Higher for Sensitive Skin

“I have sensitive skin, can I still get laser treatment?” gets a conditional answer from me. What matters is how the skin is behaving right now, and that shifts what gets checked before anything is scheduled. Several studies have reported that rosacea patients tend to show reduced epidermal barrier function and lower stratum corneum water-holding capacity, and individual thresholds for irritation vary considerably.

Here’s what we go through in consultation:

✅ CHECK POINT

• Any flaking, stinging, or burning in the last two weeks
• What triggers flushing (temperature change, alcohol, spicy food, emotional stress) and how long it lasts
• How often retinoids, acids, or exfoliants are used, and the date of last use
• History of previous laser, peel, or skin booster treatment (when, where, how skin responded afterward)
• Any history of pigmentation or scarring left behind, or a tendency toward keloid formation
• Current medications and photosensitivity
• Pregnancy or breastfeeding status
• How much time is available for recovery after treatment

When sensitivity looks elevated, we start with a low-intensity test spot on a small area, watch the response, and widen the treated area from there. At our Seocho clinic, the consulting physician is the one who carries out the treatment, so whatever the test spot shows carries directly into the next session. Our doctor page lists one physician, and I’ve written more about how that consultation structure works in an earlier piece on how Seocho decides between lifting treatments.

Why the Calendar Changes the Order for Pigmentation

For East Asian skin, the variable that most reshuffles the pigment-treatment sequence is ultraviolet exposure.

A team led by Kristie Mar at the University of British Columbia published a systematic review in the Australasian Journal of Dermatology in 2025 covering 14 studies and 369 cases of post-treatment pigmentation prevention in skin of color. Every subject was of Asian ethnicity, with 42% Fitzpatrick type III and 54% type IV. More than 95% of cases were triggered by laser treatment, and sunscreen was the one preventive measure that produced consistent results across the studies reviewed. Cooling air devices, by contrast, were reported to worsen pigmentation outcomes.

That finding isn’t absolute, though. A 2026 network meta-analysis in Lasers in Surgery and Medicine reported that sunscreen alone did not significantly lower pigmentation rates compared with a placebo arm. Read together, the two point toward sunscreen being a baseline requirement rather than something that eliminates the risk on its own.

The pigment treatments themselves also deserve a modest read on results. The same research group published a separate review in the Journal of Cutaneous Medicine and Surgery in 2024, covering 1,356 skin-of-color patients across 48 studies. Laser was the only approach that produced complete clearance in some patients, at 26%, but cases of treatment-induced pigmentation were reported in the same body of studies.

A randomized controlled study published in the Journal of Dermatological Treatment in 2024 found that post-treatment redness and daytime outdoor activity were both prognostic factors for pigmentation afterward. That’s part of why, if a trip includes long stretches of outdoor sightseeing, pushing the pigment stage to a later visit tends to be the more reasonable call.

The sun-exposure standard behind melasma management comes from the International Society of Dermatology’s 2024 guideline: avoid direct exposure between 10 a.m. and 3 p.m., reapply an SPF50+ sunscreen that also covers UVA and visible light every three hours, and favor tinted, iron-oxide formulas since visible light triggers pigment too.

Telling Apart Red Marks, Brown Marks, and Depressed Scars

What acne leaves behind gets lumped together as “acne scarring,” but clinically it splits into three categories.

Red marks (post-inflammatory erythema) appear where inflammation has dilated or damaged the surface-level blood vessels, leaving a pink or red mark. Pressing on it typically blanches the color temporarily, and it tends to fade gradually on its own.

Brown marks (post-inflammatory hyperpigmentation) are flat brown or gray-brown spots from melanocytes that were overstimulated during inflammation. Pressing doesn’t change the color. The two look similar but come from different tissue processes, and skipping the distinction is how people spend months on the wrong approach without seeing change.

Depressed scars involve a loss of dermal collagen structure that leaves the surface indented. The common classification splits them into ice-pick, boxcar, and rolling types, and how much surface-level laser alone can improve each type differs. Ice-pick scars, narrow and deep, often see limited improvement from surface treatment alone and need separate evaluation in consultation.

Our Seocho clinic publishes pricing for its laser menu. As of August 2026: pico toning is 80,000 KRW per session, full-face pico fractional is 150,000 KRW per session, pico toning in pigment-removal mode is 200,000 KRW for a butterfly-zone area and 300,000 KRW for full face, thread-lift alone is 390,000 KRW, thread-lift combined with exosome application is 590,000 KRW, and full-face Legato is 100,000 KRW. Prices are subject to change, and which item applies is decided only after the distinctions above are worked through in consultation; the figures listed are per-item list prices and don’t include promotions or package pricing.

Where to Start When the Trip Is Short

Most patients visiting from abroad have a two-to-seven night stay. I don’t recommend packing several treatment categories into one visit on a short timeline. Overlapping reactions make it hard to tell which treatment caused which response, and there isn’t enough recovery window before the next round of stimulation would go in.

For a stay of three days or less, we usually set the goal at barrier stabilization and a low-energy pigment approach at most, since that carries the lighter recovery load. With five or more days, and the ability to keep up sun protection after returning home, we can widen the conversation to include scar remodeling. If it’s summer or the itinerary includes a lot of outdoor time, pushing the pigment stage to a future visit and working on a different track this time is sometimes the better call.

How soon we check progress depends on the recovery stage involved; I’ve laid out how that follow-up schedule works in an earlier piece on recovering from a skin procedure in Seoul.

Our Seocho clinic sees patients on weekday evenings and weekends, which makes it easier to fit an additional check-in into a short stay. Japanese-, Chinese-, and English-speaking staff are on-site, so the questions above can be worked through directly, through interpretation, without losing anything to translation. After returning home, follow-up can continue through the same consultation channel used to book the visit.

Results and recovery vary by individual. If redness, swelling, or pigment changes last longer than expected, or pain intensifies, get it checked by a physician rather than waiting it out.

FAQ

Does melasma clear up in one session?

Not reliably, and I wouldn’t promise that in consultation. Melasma is classified as a chronic, relapsing pigmentation condition, and the International Society of Dermatology’s 2024 guideline treats it as something that needs ongoing management rather than a single fix. The usual approach is to space out sessions, watch the response, and adjust intensity as it goes.

Can pico toning still work for sensitive skin?

We evaluate first. That means checking barrier condition, recent irritation history, and any flushing tendency, then running a small test spot if needed before deciding. If sensitivity looks high, we may adjust intensity and spacing, or recommend working through an earlier stage before pigment treatment.

Can pores and scars be addressed on the same visit?

Sometimes, since both sit on the same dermal-remodeling track. But we still split treatment by area and intensity, and putting high-intensity stimulation across the whole face in one session isn’t something we recommend given the recovery load involved. We confirm the trip length and how many recovery days are available before deciding.

How much sun protection is needed after returning home?

Based on the International Society of Dermatology’s 2024 guideline, that means reapplying an SPF50+ sunscreen that also covers UVA and visible light every three hours, and limiting direct exposure between 10 a.m. and 3 p.m. Visible light triggers pigment too, so a tinted, iron-oxide formula can help. After pigment treatment specifically, this is closer to a condition for keeping the results than an optional extra.
