Acne marks and scars: can the same laser treat them? Distinguishing red, brown and depressed marks
Full translation of the Korean article. Translation checked for completeness, numerical consistency and medical meaning; separate medical review of this translation is pending. Translation updated: 2026-10-28.
Red acne marks, brown pigmentation and depressed scars should not all receive the same “acne scar” package. First assess vascular and inflammatory responses for red marks, post-inflammatory hyperpigmentation for brown marks, and tissue loss or tethering for depressed scars; also distinguish whether active acne remains. Photos may show only color or only surface contours, so establish the goals of lasers, RF microneedling, subcision, CROSS or medication after the physician’s examination.
Classify the “marks” in the mirror in three ways: color, depth and activity
First check whether redness fades with pressure and represents vascular erythema; second, whether brown or gray changes are post-inflammatory hyperpigmentation; third, whether side lighting reveals true depressed rolling, boxcar or ice-pick scars. At the same time, record whether new inflammatory lesions or comedones keep appearing. List the problem to treat, device, wavelength, mode, tip, scar technique, areas, sessions and recovery separately in the quote; do not judge by a package name such as “pico plus Potenza” alone.
| Observation | Possible problem | Treatment goals to discuss |
|---|---|---|
| Flat red marks | Post-inflammatory erythema or vascular response | Inflammation control, vascular treatment and UV management |
| Flat brown or gray marks | Post-inflammatory hyperpigmentation | Pigment diagnosis, topical agents and conservative laser treatment |
| Depressions visible in side lighting | Atrophic scars and tethering | Scar-type-specific remodeling, subcision or CROSS |
| Raised, firm scars | Hypertrophic scars or keloids | Assessment for other scar treatments, injections or lasers |
| New painful acne | Active inflammation | Control inflammation before scar procedures |
Definitions and how the treatments work
Pigment, vessels and scars are different targets. A randomized study comparing nonablative fractional laser with microneedling assessed improvement of depressed scars; it did not treat red marks or brown PIH as the same outcome. Applying pigment lasers uniformly to deep tethered scars or fractional remodeling uniformly to flat brown marks can create a mismatch in expectations and recovery.
Potential benefits and limitations
Distinguishing the problems can reduce unnecessary intensive procedures and allow separate assessment times and repeat-treatment plans for redness, pigmentation and depressions. Suitable treatment aims to improve appearance but cannot erase every mark at once. Deep scars may require multiple methods and sessions, while PIH may take time alongside management of sun exposure and inflammation.
Who can seek a consultation and how suitability is assessed
Adults with residual color changes or uneven skin contours after acne may seek consultation. Report active acne, herpes, dermatitis, pregnancy, breastfeeding, isotretinoin, antibiotics, retinoids or lightening products, keloid or PIH history, recent tanning, peels or lasers and previous scar treatments. Raised or suddenly changing lesions require diagnosis before cosmetic treatment.
Procedure, recovery and scheduling
The physician assesses color, depressions, tethering and active inflammation using front and side lighting and palpation. Compare vascular approaches for red marks, pigment and topical care for brown marks, and fractional treatment, RF microneedling, subcision or CROSS for depressed scars. Redness, swelling, crusts, bruising and PIH may follow treatment, so plan photography, sightseeing, flights and continuity of care after returning home.
Side effects, contraindications and symptoms requiring medical attention
Burns, blisters, infection, PIH, hypopigmentation, persistent erythema, worsening acne, scars, nodules and overtreatment are possible. Spreading redness, pus, fever, severe pain, blisters, prolonged color changes or firm lumps require medical assessment. Do not mistake differences in lighting or swelling in before-and-after photos for proof of scar improvement.
Differences in approach by mark type
| Category | Role and goals | What to check |
|---|---|---|
| Red marks | Assess vascular or inflammatory erythema | Active inflammation, skin tone and vascular-laser risks |
| Brown marks | Distinguish PIH, melasma and other dark spots | Sun exposure, irritation, skin tone and laser intensity |
| Depressed scars | Assess rolling, boxcar and ice-pick scars and tethering | Choose fractional treatment, RF, subcision or CROSS |
Questions and answers for a medical consultation
These consultation questions were compiled from the literature and do not represent a clinician interview or an individual prescription. Clinical review of the new article has not yet been completed.
Q. Are red marks also acne scars?
A. Flat red marks may differ from depressed scars, so assess vascular and inflammatory responses first.
Q. Can one pico laser treat both pigmentation and depressions?
A. Goals vary by mode; deep tethering and ice-pick scars cannot be addressed in the same way.
Q. Can scar procedures be done while acne is still developing?
A. Active inflammation often needs to be controlled first, but clinicians decide treatment extent and timing individually.
Consultation with the SEOLREIM clinic director and signature programs
SEOLREIM Clinic describes its principles of consultation and treatment directly by the physician, genuine products, correct quantities and attentive care. Consultation first distinguishes skin condition and goals, then confirms the products and devices actually available, approvals, dose or energy plans, recovery and risks. SEOLREIM does not group its Silky Pore, Fraxel, pico fractional and Juvelook programs under the single label “acne scars”; the physician personally distinguishes red marks, brown PIH, depressions, tethering and active acne. Under these principles, confirm the device, tip, areas and goals at each stage.
Booking, languages, location and guidance for international visitors
Visitors seeking information on acne marks versus scars in Korea at Gangnam or Seoul dermatology clinics should send photos in natural and side lighting, the frequency of new acne, oral and topical medications, and previous laser and scar treatments. Before booking a clinic near Gangnam Station or elsewhere in Korea, confirm consultation language, interpretation, repeat treatment and the scope of continuing care after returning home. SEOLREIM Clinic is on floor 11 of Gangnam8258 Building, approximately 1 minute from Exit 3 of Gangnam Station. Book through the website’s KakaoTalk consultation, Naver booking or telephone channels. Overseas visitors comparing dermatology clinics in Gangnam, Seoul, near Gangnam Station or in Korea should prepare medication, allergy, recent treatment and departure details. When booking, state your preferred language, such as Japanese, Chinese, Arabic, Mongolian or Indonesian, and whether interpretation is needed; confirm actual support availability and costs. Ongoing consultation availability in every language and same-day treatment cannot be guaranteed. Also agree during consultation on how to report adverse reactions after returning home and the follow-up schedule.
