Fractional laser and microneedling remodel dermal collagen over a planned series of 3 to 6 sessions, with red early marks and white mature marks responding differently.
Stretch marks treatment near Hongdae, Seoul uses fractional laser and microneedling to create controlled micro-injury that remodels dermal collagen and elastin, softening the marks over a series. Red early marks respond faster than mature white marks, so the clinic’s doctors tailor the modality and session count at consultation.

Stretch marks, medically called striae distensae, are dermal scars that form when skin is stretched faster than its collagen and elastin can adapt, during growth spurts, pregnancy, rapid weight change, or muscle gain. They appear first as red or purple lines (striae rubrae) and later fade to thin, silvery-white marks (striae albae). Treatment does not simply bleach the colour; it rebuilds the damaged dermis so the skin looks smoother and more even.
The two core in-clinic modalities are fractional laser and microneedling. Fractional laser delivers controlled columns of energy that trigger collagen and elastin remodelling, while microneedling uses fine needles to induce a similar healing response with generally shorter downtime. Both aim to thicken and reorganise the dermis under the mark so it blends better with surrounding skin over a planned series.
At Reberry Clinic, stretch mark care is doctor-led and matched to whether your marks are red or white. For international patients near Hongdae (Hongik Univ.) Station — 홍대입구역, care is provided across our Seoul locations (Gangnam, Myeongdong), easily reached from the station with full English support.
Both fractional laser and microneedling work by controlled micro-injury that switches on the skin’s own repair. Fractional laser vaporises or heats tiny columns within the dermis, leaving surrounding tissue intact so healing is faster; the wound-healing cascade lays down fresh collagen and elastin that thickens the thinned scar. Microneedling creates hundreds of microchannels with fine needles, prompting a comparable collagen-induction response but usually with milder redness and shorter downtime, which suits sensitive skin and darker tones. Red marks (striae rubrae) still have active blood vessels and living fibroblasts, so they respond more readily and often need fewer sessions. White marks (striae albae) are older, less vascular, and thinner, so they typically require more sessions and are sometimes treated with combined protocols. Because the response is biological remodelling rather than instant removal, results build gradually over weeks between sessions, and the clinic’s doctors calibrate energy and needle depth to your skin tone to protect pigment.

Doctors classify marks as red or white and check skin tone, since these 2 factors decide modality, energy, and how many sessions you need.
Topical numbing is applied for about 20 to 30 minutes so the fractional laser or microneedling session stays comfortable.
The device makes thousands of controlled micro-wounds per pass, triggering the collagen and elastin remodelling that rebuilds the dermis.
Over about 4 weeks the skin lays down fresh collagen, which is why sessions are spaced roughly a month apart across the series.
Most plans run 3 to 6 sessions, with red marks often needing fewer than mature white marks, reviewed and adjusted by your doctor.
See representative outcomes from Reberry Clinic. Results build gradually and vary by individual; your plan is assessed at consultation.
The clinic’s doctors classify your marks as red or white, check skin tone, and recommend fractional laser, microneedling, or both, in English.
After about 20 to 30 minutes of numbing, a session usually takes 20 to 45 minutes depending on the treated area and modality.
Plans typically run 3 to 6 sessions spaced about 4 weeks apart, allowing the dermis to remodel between visits.
Softening builds gradually over weeks, with red marks often improving faster than white marks, reviewed by your doctor each visit.
Results tend to hold, and daily sunscreen plus gentle skincare protect the treated area and support ongoing collagen quality.
The most suitable option depends on whether your marks are red or white, since fractional laser and microneedling each fit different marks and skin tones. There is no single answer for everyone; a consultation matches the modality to your skin. You can explore the approach on our laser treatment page.
Patients near Hongdae (Hongik Univ.) Station — 홍대입구역 are cared for at our Seoul locations in Gangnam and Myeongdong, both easily reached from the station with English support. A consultation there assesses your marks and plans treatment. See treatments on our laser treatment page.
It works by controlled micro-injury: fractional laser or microneedling creates tiny wounds that trigger the skin to rebuild collagen and elastin in the dermis. This thickens and reorganises the thinned scar so it blends better with surrounding skin. Because it is biological remodelling, results build gradually over a series rather than instantly.
Red marks (striae rubrae) are early and still vascular, so they respond faster and often need fewer sessions. White marks (striae albae) are mature, thinner, and less vascular, so they usually need more sessions and sometimes combined modalities. Your doctor identifies which type you have and plans accordingly at consultation.
Discomfort is managed with topical numbing applied about 20 to 30 minutes before treatment. Fractional laser feels like warm prickling, while microneedling is generally milder. Most patients tolerate sessions well, and your doctor adjusts settings for comfort. You can read about related options on our skin care page.
Downtime depends on the modality. Fractional laser usually causes a few days of redness and mild micro-crusting, while microneedling tends to be shorter with mild redness settling within a day or two. Your doctor explains expected recovery so you can plan sessions around work and travel comfortably.
Most plans run about 3 to 6 sessions spaced roughly 4 weeks apart, with red marks often needing fewer than mature white marks. The exact number depends on mark type, area, and how your skin responds, which your doctor reviews between visits. See our Rejuran Healer page for complementary options.
Stretch marks are scars, so treatment softens and blends them rather than fully erasing them. Realistic goals are improved texture, colour, and evenness with surrounding skin over a series. Your doctor explains achievable outcomes honestly at consultation so your expectations match what treatment can deliver.
Improvement builds gradually over several weeks as collagen remodels, not after one session. Red marks often fade faster than white marks, which improve more slowly. Your doctor reviews progress each visit so the plan stays matched to how your skin is responding across the series.
Common areas include the abdomen, thighs, hips, arms, and breasts, essentially anywhere marks have formed from stretching. Larger zones take more treatment time per visit. Your doctor assesses the area at consultation and plans coverage across the series. You can learn more on our laser treatment page.
Yes, a supportive skincare routine can help maintain results between sessions. A tailored skin care routine supports the skin barrier and collagen quality. Your doctor recommends products that complement, not duplicate, your in-clinic stretch mark plan for the best overall outcome.
Most adults with red or white marks who want gradual improvement are suitable candidates. A consultation classifies your marks, checks skin tone, and confirms which modality fits best. Those with a history of keloid scarring need careful assessment first, which your doctor discusses before starting any plan.
Yes, with adjusted settings. Deeper tones may need more conservative laser energy to protect pigment, and microneedling is often favoured for its gentler profile. Your doctor calibrates energy and needle depth to your skin so the plan is both safe and effective, which is confirmed during your consultation.
Daily sunscreen, gentle moisturising, and avoiding sun on treated skin are essential to protect results and prevent pigment changes. Avoid picking any micro-crusting after laser. A skin care routine supports healing between visits, and your doctor gives tailored aftercare instructions each session.
For a first session, 2 to 3 days is comfortable, covering a consultation, the procedure, and a short review. Because plans run as a course, many international patients begin in Seoul and continue on return visits. Our English-speaking team, reachable from 홍대입구역, helps coordinate timing around your travel.
Yes, flying within a day or so is generally fine, as these procedures are minimally invasive. Cabin air is drying, so moisturise and keep treated skin out of the sun. If you had fractional laser, expect a few days of redness and follow the aftercare your doctor provides while you travel.
International patients can complete a stretch mark course across one or more visits, with remote check-ins in English between trips so the plan stays on track. You can continue supportive skin care at home, and your treatment notes are kept on file for continuity across visits.
