Scar Revision in Seoul: Laser, Injections and Subcision for Smoother, Flatter Scars
Surgical, injury, acne and raised scars each respond to different tools. A dermatologist combines fractional CO2 laser, RF microneedling, steroid injections or subcision to make scars flatter, smoother and less visible.
What is the best treatment for scars?
The best scar treatment depends on the scar type: fractional laser and RF microneedling for flat or indented scars, steroid injections and silicone for raised or keloid scars, and subcision or filler for tethered depressed scars. Most scars need 3–6 sessions and improve by 50–80% rather than disappearing completely.
Scar types
Which scars can be improved?
Treatment starts with identifying whether the scar is raised, flat, indented, red or pigmented.
Surgical and injury scars
Fractional laser blends texture and colour.
Raised (hypertrophic) scars
Steroid injections and silicone flatten thick scars.
Keloids
Injections, sometimes combined with laser; recurrence risk is discussed.
Acne scars
Specialised plan on acne scar treatment.
Burn scars
Gentle fractional and vascular laser; see burn scar treatment.
Stretch marks
A different scar type; see stretch mark treatment.
How it works
How scar revision works
Fractional lasers and microneedling create microscopic channels that trigger collagen remodelling, smoothing the scar edges. Injections soften excess collagen in raised scars, and subcision releases fibrous bands that pull scars down.
- After each session: redness and small crusts for a few days
- 4–6 weeks: next session as collagen remodels
- 3–6 months: visible flattening and smoother texture
- Maintenance: sun protection prevents darkening

- Scars at least 6–8 weeks old (earlier laser can help some)
- People who can follow a multi‑session plan
- Those with realistic expectations of improvement
Safety & side effects
- Darker skin has a higher risk of post‑laser pigmentation; settings are adjusted
- Keloid‑prone patients need careful planning
- Steroid injections can thin skin if overused
- Avoid isotretinoin within recent months before aggressive laser
No treatment erases a scar completely; the goal is a flatter, smoother and less noticeable scar.

| Strength | Strong resurfacing | Deeper, gentler surface |
| Downtime | 5–7 days | 2–3 days |
| Darker skin | More caution | Generally safer |
| Best for | Texture, flat scars | Indented scars, pores |
