Fractional laser and microneedling remodel the dermis over a series of 3 to 6 sessions, softening the texture and colour of striae rather than erasing them in 1 visit.
Stretch marks treatment for foreigners in Seoul mainly uses fractional laser and microneedling to stimulate collagen and improve the texture and colour of striae over 3 to 6 sessions spaced about 4 weeks apart. Reberry Clinic offers this across its Seoul locations with full English support, so international patients can plan a first assessment and session within a short stay.
One-on-One guidance from a dedicated doctor, ensuring your skin is professionally monitored and treated from start to finish.
Fluent assistance in English, Japanese, and Chinese, making communication clear, respectful and comfortable for international patients.

Stretch marks treatment for foreigners refers to a set of in-clinic procedures that improve the appearance of striae distensae, the linear bands that form when skin stretches faster than its collagen and elastin can adapt. They commonly appear after pregnancy, rapid growth, weight change, or muscle gain, on the abdomen, thighs, hips, and arms. Treatment softens their texture, depth, and colour rather than removing them completely.
The two most established approaches are fractional laser, which creates controlled microthermal zones that trigger dermal remodelling, and microneedling, which induces collagen through fine controlled punctures. Fresh red or purple striae (striae rubrae) generally respond faster than older white striae (striae albae), which need a longer, staged plan.
For international patients, English-language planning and realistic timelines matter as much as the device itself. Reberry Clinic serves visitors across three Seoul-area locations (Gangnam, Myeongdong, Incheon Airport), with each plan reviewed by the clinic’s doctors so that expectations, session numbers, and aftercare are clear before you start.
Fractional laser delivers energy in a grid of tiny columns, treating a fraction of the skin at a time while leaving surrounding tissue intact to speed healing. This controlled injury prompts fibroblasts to lay down new collagen and elastin, gradually thickening the thin, atrophic floor of a stretch mark and improving its texture over weeks. Ablative fractional CO2 lasers act more intensively with more downtime, while non-ablative fractional lasers are gentler with shorter recovery, and the choice depends on striae age and skin tone.
Microneedling reaches a similar goal mechanically, using fine needles to create hundreds of micro-channels that trigger the same collagen-induction cascade with generally less pigment risk in darker skin. In practice, the clinic matches the modality and settings to whether your striae are red or white, your skin type, and how much downtime your travel dates allow.

The clinic’s doctors examine your striae, noting whether they are red or white and which of 1 to 3 body areas to treat.
Topical anaesthetic is applied for about 20 to 30 minutes so the session stays comfortable.
Fractional laser or microneedling is passed over the area, usually taking 20 to 40 minutes depending on size.
Over the next 4 to 12 weeks, new collagen remodels the treated dermis and texture gradually improves.
Most plans use 3 to 6 sessions spaced roughly 4 weeks apart for cumulative improvement.
Sun protection and periodic touch-ups over 6 to 12 months help hold and extend results.
See representative outcomes from Reberry Clinic. Results build gradually and vary by individual; your plan is assessed at consultation.
The clinic’s doctors assess your striae, skin type, and goals, then explain the modality, session count, and expected downtime in English.
After 20 to 30 minutes of numbing, a fractional laser or microneedling pass treats the area in about 20 to 40 minutes.
A single session including preparation typically takes around 1 hour at the clinic.
Texture and colour improve gradually over 4 to 12 weeks, building across 3 to 6 sessions.
Sun protection, gentle skincare, and periodic touch-ups over 6 to 12 months help maintain results.
For most international patients, fractional laser and microneedling are the mainstays, chosen by striae age and skin tone rather than a single option for everyone. Fractional laser suits textured white striae, while microneedling lowers pigment risk in darker skin. Your plan is set by the clinic’s doctors; you can read more on our laser treatment page.
No treatment reliably erases stretch marks, since striae are scar-like changes in the dermis, but fractional laser and microneedling can noticeably soften their texture, depth, and colour. Fresh red striae respond better than older white ones. The realistic goal is meaningful improvement over a staged plan, not a one-time fix, which is why several sessions are usually recommended.
Good candidates have red or white striae from pregnancy, growth spurts, weight change, or muscle gain and healthy skin over the area. Fractional laser suits textured marks, while microneedling is often preferred for darker skin. A consultation confirms suitability; you can also explore our skin care options to support results between sessions.
Most patients feel only mild discomfort, usually a warm or prickling sensation, because topical numbing is applied for about 20 to 30 minutes beforehand. Fractional laser can feel warmer, while microneedling feels like light pressure and pinpricks. Any discomfort is short-lived, and the team adjusts settings for comfort during your session.
Downtime is usually short, with redness and mild swelling for a few days and light flaking after fractional laser, or 1 to 3 days of redness after microneedling. You can typically return to normal activity quickly while avoiding sun, heat, and heavy sweating. Plan any procedure a few days before beach or pool time on your trip.
Most plans use 3 to 6 sessions spaced about 4 weeks apart, because collagen remodelling is gradual and cumulative. Red striae may need fewer sessions than older white ones. The clinic’s doctors confirm your number at consultation; combining approaches is sometimes suggested, which you can discuss alongside our skin care options.
Improvements from collagen remodelling are long-lasting once achieved, as the new dermal support does not simply disappear, though skin continues to age. Sun protection and periodic touch-ups over 6 to 12 months help maintain and extend results. Stretch marks will not return in the same way, but new ones can form with future rapid stretching.
It depends on your striae and skin tone: fractional laser gives stronger remodelling for textured white marks, while microneedling carries a lower pigment risk and often suits darker skin. Many patients do well with either or a combination. The clinic’s doctors match the choice to you; see more on our laser treatment page.
Yes, stretch marks treatment is often combined with collagen-supporting skincare or complementary procedures on separate areas, planned so recovery does not overlap. The clinic’s doctors sequence sessions to keep downtime manageable, especially for a short trip. You can also ask about pairing with our skin care options for overall skin quality.
Common effects are temporary redness, mild swelling, and light flaking or pinpoint marks that settle within days. Less common risks include temporary pigment change, especially in darker skin without sun protection, which is why modality choice matters. Serious complications are uncommon when settings suit your skin, and the clinic reviews your history to reduce risk.
Aftercare centres on gentle cleansing, moisturising, and strict daily sun protection for several weeks, plus avoiding heat, saunas, and heavy sweating right after each session. Do not pick at flaking skin. The clinic gives written English instructions, and you can pair recovery with our skin care options to support the treated area.
Fresh red or purple striae (striae rubrae) generally respond faster because the skin is still actively remodelling, while older white striae (striae albae) need a longer, staged plan. Both can improve, but expectations differ. The clinic’s doctors assess your stage at consultation and set a realistic session count and timeline based on what they see.
Yes, with the right modality and settings, though darker skin carries a higher risk of temporary pigment change with aggressive energy. Microneedling is frequently preferred for this reason, and laser settings are adjusted conservatively. The clinic reviews your skin type first; you can read about device options on our laser treatment page.
A first assessment and one session usually fit within 2 to 3 days, which suits many international visitors. Because a full plan spans several sessions over weeks, some patients start in Seoul and continue on later trips or with remote guidance. The English team helps schedule sessions around your travel dates during your consultation.
Yes, flying after a stretch marks session is generally fine, since downtime is mild and localised, though you should keep the area clean, moisturised, and out of strong sun. Avoid saunas or heavy exercise for a few days. Confirm your specific aftercare with the clinic, especially if several body areas were treated in one visit.
The clinic keeps notes and photos on file so care can continue across visits, and the English team can offer remote check-ins between sessions. This matters for international patients completing a staged plan over time. Ask about ongoing support and how to pair sessions with our skin care options during your consultation.
