Stretch Mark Treatment in Seoul: Fading Red and White Striae
The short answer
Stretch mark treatment in Seoul uses fractional laser, RF microneedling, vascular or toning laser and regenerative injections such as PRP to improve the color and texture of striae. In Gangnam a session typically costs about ₩150,000–₩600,000 per area, with 2–7 days of redness or crusting. Most people need 3–6 sessions 4–6 weeks apart; marks soften and blend but do not disappear.

What stretch marks are
Stretch marks, or striae, form when skin stretches faster than its collagen and elastin can adapt, causing fine tears in the dermis. They are common during puberty, pregnancy, rapid weight change and muscle building, and can also follow long-term steroid use. New marks are red or purple (striae rubra) because of inflamed blood vessels; over months they fade to pale, silvery, slightly sunken lines (striae alba).
Both types can be improved, but new marks respond more readily because the tissue is still active. Old white marks need more sessions and the change is subtler.
Treatment options in Seoul
| Treatment | Best for | Downtime |
|---|---|---|
| Fractional CO2 or Er:YAG laser | Texture and depth of white marks | 5–7 days |
| RF microneedling (Potenza and similar) | Texture with lower pigment risk | 2–3 days |
| Vascular laser or pico toning | Redness in new marks; brown tone | Minimal |
| PRP or exosome therapy | Supports healing and collagen | 1–2 days |
| Peels or resurfacing | Surface texture | 2–5 days |
| Combination therapy | Most patients | Varies |
Seoul clinics frequently combine RF microneedling or fractional laser with PRP or exosomes in one session. You can read more in our guides to stretch mark microneedling and fractional laser.
What treatment feels like
Numbing cream is applied for 30–60 minutes. Lasers and microneedling produce a hot, prickling sensation. Afterwards the area looks sunburned and may swell slightly; fine crusts or a sandpaper texture appear for several days and should be left to shed on their own.
Cost in Seoul
Typical Gangnam prices range from about ₩150,000 for a small area with a single device to ₩600,000 or more for a large area such as the full abdomen with combined laser and PRP. Packages of 3–5 sessions are common. Confirm the exact size of the area included in the quote.
Planning around your trip
- Allow at least 5–7 days after fractional laser before swimming or sun exposure.
- Flying is fine, but wear loose clothing over treated areas.
- Because sessions are 4–6 weeks apart, most visitors do one or two per trip.
- Use SPF on treated areas for several weeks to avoid pigment changes, particularly with darker skin tones.
Realistic expectations
Good treatment typically makes stretch marks flatter, narrower, closer to your skin color and less noticeable, with many patients reporting meaningful improvement after a full course. Complete removal is not possible. Results are long-lasting, but new marks can form with future stretching.
Choosing a clinic
Ask which devices the clinic uses, how they adjust settings for your skin tone, and how many sessions they expect for your type of marks. If you are pregnant or breastfeeding, most treatments should wait. For related options on the abdomen, see our abdomen firming guide.

Patient questions
Frequently asked questions
Can stretch marks be removed completely?
No. Treatment improves color and texture so they are less visible, but some trace usually remains.
Do old white stretch marks respond?
Yes, though more slowly. Expect more sessions and gradual texture improvement.
How many sessions are needed?
Typically 3–6, spaced 4–6 weeks apart, depending on the area and age of the marks.
Is it safe for darker skin?
Yes with appropriate settings; RF microneedling is often preferred because it carries a lower pigmentation risk.
