Why Korea for Fractional Laser Treatment?
Korea has earned its reputation as the world capital of aesthetic dermatology for good reason. Korean dermatologists undergo rigorous training, clinics invest heavily in the latest laser platforms, and fierce competition keeps prices remarkably low. For international patients, this means access to board-certified specialists using cutting-edge equipment — often at 40 to 70 percent less than comparable treatments in Western countries.
Seoul alone has thousands of dermatology clinics, with the highest concentration in the Gangnam and Apgujeong districts. Many of these clinics employ English-speaking coordinators and have years of experience treating overseas patients. Whether you have shallow post-inflammatory marks or deep ice-pick and boxcar scars, Korean clinics offer tailored treatment plans that combine multiple laser modalities for optimal results.
Understanding Acne Scars and How Fractional Lasers Work
Acne scars form when inflamed breakouts damage collagen in the deeper layers of the skin. The body's healing response can leave behind depressions (atrophic scars) or raised tissue (hypertrophic scars). Atrophic scars — which include ice-pick, boxcar, and rolling scars — are the most common type and respond well to fractional laser therapy.
Fractional lasers work by delivering thousands of microscopic laser beams into the skin. Each beam creates a tiny column of controlled thermal damage called a microthermal zone. The surrounding healthy tissue accelerates healing, stimulating new collagen production and skin remodeling. Over multiple sessions, the scarred skin is gradually replaced by smoother, more even-toned tissue. Collagen remodeling can continue for up to three months after each session, so improvements compound over time.
Types of Fractional Lasers: CO2 vs. Erbium vs. Pico
Choosing the right laser depends on your scar type, skin tone, pain tolerance, and available downtime. Here is a detailed comparison of the three most common fractional lasers used in Korean clinics.
| Feature | CO2 Fractional | Erbium:YAG Fractional | Pico Fractional |
|---|---|---|---|
| Wavelength | 10,600 nm | 2,940 nm | 1064 / 532 / 785 nm |
| Best For | Deep ice-pick and boxcar scars | Moderate rolling and boxcar scars | Shallow scars, texture, pigmentation |
| Effectiveness | Most powerful; reaches deep dermis | Strong; gentler than CO2 | Moderate; best for mild scars |
| Downtime | 7 to 14 days (redness can last weeks) | 3 to 5 days | 1 to 3 days |
| Pain Level | High (numbing cream required) | Moderate | Mild |
| Side Effect Risk | Higher (redness, PIH in darker skin) | Moderate | Low |
| Sessions Needed | 3 to 5 (4-6 week intervals) | 3 to 5 (4-6 week intervals) | 5 to 10 (2-4 week intervals) |
| Price per Session (Seoul) | $150 - $550 | $150 - $500 | $80 - $300 |
CO2 Fractional Laser
The CO2 fractional laser is considered the gold standard for deep acne scars. Its 10,600 nm wavelength penetrates the deepest of the three options, delivering powerful thermal energy that stimulates significant collagen remodeling. Korean clinics commonly use platforms like the Lutronic eCO2 and DEKA SmartXide, both developed or widely adopted in Korean dermatology.
The trade-off is a longer recovery. Expect to wear hydrocolloid patches for four to seven days after treatment, with residual redness lasting several weeks. CO2 fractional is most suitable for patients with lighter skin tones (Fitzpatrick I-III) due to a higher risk of post-inflammatory hyperpigmentation in darker skin.
Erbium:YAG Fractional Laser
The Erbium:YAG (Er:YAG) fractional laser operates at 2,940 nm, a wavelength with exceptionally high water absorption. This means it ablates tissue very precisely with less surrounding thermal damage compared to CO2. The result is a gentler treatment with noticeably shorter downtime — typically three to five days.
Erbium fractional is an excellent middle-ground choice for patients who want meaningful scar improvement without the extended recovery of CO2. It works well for moderate rolling and boxcar scars and carries a lower risk of hyperpigmentation, making it a safer option for patients with medium skin tones.
Pico Fractional Laser
Pico fractional lasers deliver ultra-short pulses measured in picoseconds (trillionths of a second). Rather than thermal ablation, they create microscopic cavities in the dermis through a photomechanical effect called LIOB (Laser-Induced Optical Breakdown). This triggers collagen remodeling with minimal surface damage.
The major advantage of pico fractional is minimal downtime — most patients return to normal activities within one to three days. However, it is less effective for deep scars and typically requires more sessions. Pico fractional is ideal for patients with shallow scars, uneven texture, enlarged pores, or darker skin tones where the risk of pigmentation changes must be minimized.

What Affects the Price?
Several factors influence your final cost:
- Scar severity and depth — deeper scars require higher energy settings and may cost more
- Treatment area — full face is more expensive than targeted zones (nose area, cheeks only)
- Laser platform — newer or premium devices may carry a surcharge
- Post-treatment care — some clinics include LED therapy, soothing masks, or regenerative treatments in the price; others charge separately
- Clinic location — Gangnam and Apgujeong clinics may charge a premium compared to clinics in other neighborhoods
What to Expect: The Treatment Process
Before Your Session
- Consultation: A dermatologist examines your scars, discusses your goals, and recommends the appropriate laser type and settings. Many clinics offer free consultations.
- Skin preparation: You may be asked to avoid retinoids, chemical exfoliants, and direct sun exposure for one to two weeks before treatment.
- Numbing: A topical anesthetic cream is applied 30 to 45 minutes before the procedure to minimize discomfort.
During Treatment
The procedure itself typically takes 20 to 40 minutes for a full face. You will feel heat and a prickling sensation despite the numbing cream, particularly with CO2 fractional. The dermatologist adjusts the laser's energy, density, and depth settings based on your specific scar pattern.
After Treatment
- Immediate: Skin will appear red and swollen, similar to a sunburn. Hydrocolloid patches or ointment are applied.
- Days 1-3: Swelling peaks. Micro-crusts form over treated areas.
- Days 3-7: Crusts begin to slough off. New pink skin appears underneath.
- Weeks 2-4: Redness gradually fades. Collagen remodeling begins.
- Months 1-3: Continued improvement as new collagen fills scarred areas.
Critical Aftercare Tips
- Sunscreen is non-negotiable — apply SPF 50+ every two hours when outdoors. UV exposure after fractional laser can cause severe hyperpigmentation and undo your results.
- Avoid makeup for at least five to seven days post-CO2 treatment.
- Keep skin hydrated with gentle, fragrance-free moisturizers.
- Skip active ingredients (retinol, AHA, BHA, vitamin C) for at least two weeks.
Choosing a Clinic in Seoul as an International Patient
What to Look For
- Board-certified dermatologist (피부과 전문의) — confirm the doctor is a licensed dermatology specialist, not a general practitioner
- English-speaking staff — many Gangnam and Apgujeong clinics have dedicated international coordinators
- Modern laser equipment — ask which specific device they use (Lutronic eCO2, Cynosure PicoSure, Cutera Secret Pro are well-regarded)
- Transparent pricing — reputable clinics provide clear quotes during consultation
- Post-treatment support — check if follow-up visits and aftercare are included
Popular Areas for Dermatology Clinics
- Gangnam Station area — highest concentration of clinics, competitive pricing
- Apgujeong Rodeo — premium clinics, celebrity dermatologists
- Sinsa-dong (Garosugil) — boutique clinics with a modern feel
- Myeongdong — convenient for tourists, many foreigner-friendly clinics
Booking Tips
- Book consultations at two to three clinics before committing — most consultations are free
- Ask about combination protocols — many Korean dermatologists combine fractional laser with subcision, TCA CROSS, or PRP for superior results on mixed scar types
- Plan your trip around recovery — schedule your laser session early in your visit so you have time to attend a follow-up before flying home
- Bring medical records — if you have a history of keloids, herpes simplex, or are on isotretinoin, inform your dermatologist
Frequently Asked Questions
Q: How many sessions of fractional laser do I need for acne scars? A: Most patients see significant improvement after three to five sessions of CO2 or Erbium fractional laser, spaced four to six weeks apart. Pico fractional may require five to ten sessions. Your dermatologist will create a personalized plan based on your scar severity.
Q: Is fractional laser painful? A: Numbing cream is always applied before treatment. CO2 fractional can still be uncomfortable — patients describe it as a hot, prickling sensation. Erbium is more tolerable, and pico fractional is the least painful of the three.
Q: Can fractional laser completely remove acne scars? A: Fractional laser can improve acne scars by 50 to 80 percent over a full course of treatment, but complete removal is rare. The goal is significant improvement in texture, depth, and overall appearance.
Q: Is fractional laser safe for darker skin tones? A: Pico fractional and Erbium fractional are generally safer for Fitzpatrick skin types IV-VI due to lower thermal damage and reduced risk of post-inflammatory hyperpigmentation. CO2 fractional requires caution and conservative settings for darker skin. Always discuss your skin type with your dermatologist.
Q: Can I fly home the day after treatment? A: It is generally safe to fly after fractional laser, but not ideal. The cabin air is very dry, which can irritate healing skin. If possible, wait at least three to five days before a long flight, and keep skin well-moisturized and protected from UV through airplane windows.
Q: What is the best time of year to get fractional laser in Korea? A: Autumn and winter (October through February) are ideal because UV exposure is lower, reducing the risk of post-treatment hyperpigmentation. Summer treatments require extra vigilance with sun protection.
