Reversing that order, especially running an aggressive resurfacing laser over pigmented skin too early, can make post-inflammatory hyperpigmentation worse instead of better. On a short trip, doing fewer things well beats stacking everything into one visit.<\/p>\n<\/blockquote>\n<p>I&#8217;m Dr. Kim Yeonjin, director at our Gangnam clinic. When patients ask me about acne marks, the real question almost never turns out to be &#8220;what should I get done.&#8221; It turns out to be &#8220;what should I get done first.&#8221; The same devices, the same session counts, can produce opposite results depending on the sequence, because pigmented skin reacts to irritation more readily, and that reaction produces more pigment.<\/p>\n<h2>The Word &#8220;Marks&#8221; Usually Covers Three Separate Things<\/h2>\n<p>Patients describing &#8220;acne scars&#8221; are almost always describing a mix of three findings.<\/p>\n<p>The first is a residual red or pink mark. This is closer to a lingering vascular change from the inflammation itself, and it tends to fade faster than pigmented marks.<\/p>\n<p>The second is brown discoloration, known clinically as post-inflammatory hyperpigmentation. A Galderma phase 4 clinical trial protocol registered with ClinicalTrials.gov describes this pigment as able to sit in the epidermis, the dermis, or both, and notes it can take months to resolve. Epidermal pigment reflects increased melanin production; dermal pigment reflects melanin that has leaked from a damaged basal layer and been taken up by macrophages below. Because the two sit at different depths, they respond to different wavelengths and need different recovery windows.<\/p>\n<p>The third is a depressed, pitted scar. This is a structural problem in the dermis, and it needs an approach built around rebuilding collagen rather than lightening pigment.<\/p>\n<p>Most patients have all three on one face at once. That&#8217;s why treating the combination as a single &#8220;acne scar package&#8221; without diagnosing which is which tends to help one problem while working against the other two.<\/p>\n<h2>If New Breakouts Are Still Active, Start There<\/h2>\n<p>Some patients come in asking about pigment while a fresh breakout is still forming along the jawline or forehead. In that case, the active inflammation comes first, not the pigment.<\/p>\n<p>A 2026 expert panel discussion summarized by the clinical dermatology outlet Dermatology Times concluded that acne-related hyperpigmentation needs concurrent management of active acne and the pigment itself, and that treating pigment alone while inflammation continues does not work well. The same discussion named topical retinoids as a first-line option and salicylic acid as a supporting exfoliant.<\/p>\n<p>The logic is straightforward. New inflammation keeps supplying new pigment. If new pigment is forming faster than existing pigment fades, repeated treatments hold the skin in place rather than improving it.<\/p>\n<h2>What Happens When a Strong Resurfacing Laser Goes First<\/h2>\n<p>Ablative resurfacing lasers have long been used to rebuild scar texture. A 2025 study in the Journal of Cosmetic Dermatology by researchers Xiaozhun Hang and Davin Sui Lim describes fractional CO2 laser resurfacing as a standard approach to atrophic acne scars, while noting that in Fitzpatrick skin types III and above, post-inflammatory hyperpigmentation is a major limitation on its use. The same paper cites hyperpigmentation rates reported after this kind of resurfacing running as high as roughly 90 percent, and in some reports close to universal, in type IV skin and darker. Many Korean, Japanese, Taiwanese, and other Chinese-heritage patients fall into that range.<\/p>\n<p>The same paper notes that non-ablative fractional lasers and radiofrequency microneedling have become widely used because they carry lower pigmentation risk, though the paper describes their dermal remodeling effect as generally falling short of CO2 resurfacing. The choice isn&#8217;t about which device is objectively superior. It&#8217;s about how much heat this particular patient&#8217;s skin can currently tolerate.<\/p>\n<p>Pigment-targeted lasers carry their own risk window too. A 2024 randomized controlled trial in the Journal of Dermatological Treatment found that post-treatment redness and daytime outdoor activity predicted new hyperpigmentation after Q-switched laser treatment for pigmented lesions, and that starting topical care two weeks after the procedure was associated with a lower hyperpigmentation rate than starting later. What a patient does in the two weeks after a session can matter as much as the session itself.<\/p>\n<h2>Resurfacing Is Rarely the First Card We Play<\/h2>\n<p>For patients carrying both pigment and pitted texture, we often place a polynucleotide-class injectable in the middle of the sequence rather than starting with a resurfacing laser. In a 2025 survey of Korean dermatologists published in Annals of Dermatology, a majority of respondents reported using polynucleotide injections for general skin regeneration purposes including fine lines, pores, and dryness, and roughly a third reported using them specifically for depressed acne scars. We use Rejuran for this purpose. Settling the skin without pushing heat too high first means the pigment or texture work that follows can often start at a gentler setting.<\/p>\n<h2>How We Sequence It: Four Stages<\/h2>\n<p>The conditions differ by patient and by area of the face, but the reasoning follows the same four stages.<\/p>\n<h3>Stage 1: Sort out what&#8217;s actually there<\/h3>\n<p>We identify the proportion of red marks, brown pigment, and pitted texture, and check whether pigment sits closer to the surface or deeper. If active inflammation is present, we pause here first.<\/p>\n<h3>Stage 2: Calm inflammation and stabilize the skin barrier<\/h3>\n<p>This stage continues until new lesions stop forming and the skin&#8217;s reaction to mild irritation settles down. Skipping this stage raises the hyperpigmentation risk of every treatment that follows.<\/p>\n<h3>Stage 3: Fade the pigment<\/h3>\n<p>Sun protection and topical care form the baseline here, layered under whatever in-office treatment the skin can currently tolerate, started conservatively and adjusted as we watch the response. Setting the intensity too high in an attempt to clear pigment quickly tends to provoke a rebound.<\/p>\n<h3>Stage 4: Address texture<\/h3>\n<p>Pitted scars and enlarged pores come last. Skin that has already cleared its pigment carries a lower risk of that pigment returning when texture treatment begins. Depending on the case, we place radiofrequency microneedling or a polynucleotide-class injectable at this stage.<\/p>\n<p>This framework shifts by area. Cheeks tend to lean toward pitted texture, jawlines toward pigment, so it&#8217;s normal for one face to sit at different stages in different zones simultaneously. We&#8217;ve written separately about the related question of sequencing when dullness and skin laxity appear together, in <a href=\"https:\/\/news.uhcell.com\/en-us\/articles\/373\">Dullness and Sagging: What&#8217;s the Right Treatment Order?<\/a><\/p>\n<h2>What to Cut When You Only Have Two to Seven Days<\/h2>\n<p>Roughly 90 percent of the patients we see travel from abroad specifically for treatment, most commonly from Japan, Taiwan, greater China, and English-speaking countries, typically staying two to seven days. Under that constraint, sequencing becomes a scheduling decision as much as a clinical one.<\/p>\n<p>The anchor point is departure day. Flying long-haul with visible redness and swelling still present, or filling the day after a procedure with outdoor sightseeing, runs directly into the same risk factors described above. Daytime sun exposure was a predictor of post-treatment pigmentation in the research we cited.<\/p>\n<p>So on a short visit, we generally recommend doing fewer things rather than more. Treatments with short recovery windows go earlier in the stay; anything with a longer reaction period gets scheduled away from departure day. It&#8217;s common for us to start the pigment stage during a Seoul visit and leave the texture stage for a return trip, documenting exactly what was done, at what intensity, and when the next session should follow.<\/p>\n<h2>Where Recovery Happens Matters for Pigment, Specifically<\/h2>\n<p>Our Gangnam location sits on the second and third floors of the UH FLAT SIGNATURE Gangnam hotel building. Our Seocho location is inside UH FLAT The Seocho. Both operate as an on-site amenity of the hotel rather than a separate building under a referral arrangement.<\/p>\n<p>That structure has a concrete implication for pigment-prone skin. During the hours right after a procedure, when sun and movement are best avoided, the path from the treatment room to a hotel room runs through the same building rather than back out onto the street. Hotel guests receive complimentary access to an oxygen chamber and vitamin IV drips, letting the recovery window continue inside the same stay. Procedures take place in a private treatment room.<\/p>\n<p>Consultation language affects sequencing decisions too. Our Gangnam location has Japanese, Chinese, and English interpreters on site. Understanding in your own language why today&#8217;s mark is pigment rather than residual redness, or why a particular treatment is being held back this visit, lowers the odds of receiving a conflicting combination at the next clinic in the next city. We&#8217;ve also written about what to do if an unexpected reaction shows up after a procedure, in <a href=\"https:\/\/news.uhcell.com\/en-us\/articles\/372\">What to Do If a Procedure Goes Wrong in Seoul<\/a>.<\/p>\n<h2>What We Ask First in Consultation<\/h2>\n<p>The questions we ask at a first consultation are largely the same across patients: whether new acne is currently active, whether any procedure was done elsewhere in the last three months, current medications, recent sun exposure, and departure date.<\/p>\n<p>That last question can look clinically minor, but it&#8217;s what determines where the recovery window gets placed. At our Gangnam location, I trained at Seoul National University&#8217;s graduate program and completed my residency at Seoul National University Hospital, and I&#8217;ve worked as an Allergan faculty member and as a Potenza and Ulthera Z Key Doctor. Keeping diagnosis, planning, treatment, and follow-up with one physician matters here because these decisions are linked; changing one stage changes what&#8217;s safe to do at the next.<\/p>\n<h2>FAQ<\/h2>\n<h3>Can I tell the difference between a red mark and brown pigment myself?<\/h3>\n<p>A rough distinction is possible. Red marks tend to reflect a vascular reaction, while brown marks reflect remaining melanin. The two frequently overlap on the same area of skin, and whether brown pigment sits near the surface or deeper isn&#8217;t something you can judge by eye.

Trying to compress the timeline through session count alone tends to matter less than keeping up daily sun protection and topical care between visits.<\/p>\n<h3>I have sightseeing booked after treatment. Is that a problem?<\/h3>\n<p>The relevant factors are how much sun exposure and friction the skin sees afterward.
