Pico Fractional Laser in Seoul (Hongdae): Scars, Pores and Texture
Pico fractional laser delivers ultra-short picosecond pulses in a fractional dot pattern, creating tiny zones of micro-injury beneath the surface that trigger new collagen while leaving the skin surface largely intact. It helps acne scars, enlarged pores, fine lines and rough texture, and can also brighten tone. At KLEAM Clinic Hongdae it takes about 15 to 30 minutes after numbing, and redness usually settles in 1 to 2 days, so it fits short trips.

How it works
Pico fractional laser splits picosecond (trillionth-of-a-second) laser pulses into a grid of tiny beams. Instead of burning away the skin surface, the energy creates microscopic pockets of controlled injury in the deeper layer, and the healing response stimulates fresh collagen and elastin.
After numbing cream, most people feel light snapping and warmth. The skin may look pink for a day or two and can feel slightly dry, but there is usually little or no peeling. Collagen remodeling continues for weeks, so results build gradually over a series of sessions.
Because the surface stays largely intact, pico fractional laser generally carries a lower risk of post-inflammatory pigmentation than stronger resurfacing lasers. The doctor still adjusts settings for your skin type and concern.
How it compares
| Compared with | Difference |
|---|---|
| Fraxel | Fraxel is a non-ablative fractional laser that works with heat, while pico fractional laser uses ultra-short pulses and usually causes milder redness; the doctor chooses based on your scars and skin. |
| Microneedling | Microneedling creates channels mechanically, while pico fractional laser uses laser energy; both build collagen with short downtime and can be combined. |

Frequently asked questions
How much downtime should I expect?
Most people have mild redness for about 1–2 days, sometimes with slight dryness or fine flaking. Many visitors go back to sightseeing the next day with sunscreen and a hat.
Does pico fractional laser hurt?
Numbing cream is applied beforehand, so most people feel only light snapping and warmth, and most find it very tolerable. If you have any questions before booking, message us on WhatsApp or KakaoTalk and our English-speaking staff will help.
How many sessions do I need for acne scars?
Texture and pores often look smoother after the first sessions, while acne scars usually need 3–5 sessions spaced about 3–4 weeks apart. Combining pico fractional laser with skin boosters or other treatments is common. The doctor will suggest a plan after examining your scars.
Can I fly after pico fractional laser?
Yes. Downtime is short, but cabin air is very dry, so keep the skin moisturized during the flight and use sunscreen when you land.
Is it safe for Asian or darker skin?
Pico fractional laser generally has a lower risk of post-inflammatory pigmentation than stronger resurfacing lasers, but the doctor still adjusts the settings for your skin type, and strict sun protection afterwards is important. If you have any questions before booking, message us on WhatsApp or KakaoTalk and our English-speaking staff will help.
How much does pico fractional laser cost?
The price depends on the area and treatment intensity. Please send your photos and concern on WhatsApp or KakaoTalk, and our staff will share current prices before your visit. Results and suitability vary from person to person, so the doctor confirms the best plan during your consultation.

Pico Fractional Laser in Hongdae – Smooth Scars & Refine Texture
Want smoother skin and softer acne scars without long downtime? Pico fractional laser uses ultra-short picosecond pulses to stimulate collagen beneath the skin surface—improving scars, enlarged pores, fine lines and uneven texture while keeping recovery short. At our clinic in Hongdae, the doctor tailors each session to your skin type and concern.
What is Pico Fractional Laser?
Pico fractional laser is a non-surgical skin renewal treatment that delivers picosecond laser pulses through a fractional (dot) pattern. These pulses create tiny zones of controlled micro-injury beneath the surface, stimulating the body’s natural healing process and new collagen production while the skin surface stays largely intact.
It is commonly used for:
- Acne scars and uneven texture
- Enlarged pores
- Fine lines and early wrinkles
- Dull skin and uneven tone
Why Choose Pico Fractional Laser?
Key Benefits:
✅ Improves acne scars and rough texture
✅ Refines enlarged pores
✅ Boosts collagen for firmer, smoother skin
✅ Can brighten overall tone
✅ Short downtime—usually 1–2 days of redness
✅ Settings tailored to your skin type
What to Expect During Treatment
Your skin is cleansed and numbing cream is applied for comfort. The laser session takes about 15–30 minutes depending on the area. Mild redness and warmth are normal for about 1–2 days, and most people return to daily activities the next day with sunscreen.
Who is a Good Candidate?
Pico fractional laser may suit adults with acne scars, enlarged pores, fine lines or rough texture who want improvement with little downtime. It may not be suitable during active acne breakouts, infection, pregnancy or recent strong tanning. A consultation is required to assess suitability.
When Will You See Results?
Skin often looks smoother after the first sessions, and improvements build as collagen rebuilds. A series of about 3–5 sessions spaced 3–4 weeks apart is commonly recommended. How long results last varies by person and is confirmed at consultation.
