Fractional laser treats skin in a grid of microscopic columns and leaves the skin between them intact, so it heals in days. In Korea the field sorts into three families: ablative (CO2, erbium YAG) that vaporizes deeper columns for atrophic scars, non-ablative (pico and 1550nm) that heats without breaking the surface for pores and tone, and RF microneedling (Potenza) that drives radiofrequency down needles. At RE:BERRY Gangnam a physician grades your skin first, then matches the family. The choice comes from your concern, and a fixed menu never decides it.
Effects & Progress
Effects & Progress
One graded pass can weigh pores, uneven tone, scars, and slack texture together, because the physician sorts each concern into a family first and sets the density to whichever ones matter most for your skin.
Treated zones look flushed and feel warm. Non-ablative and RF microneedling settle within 1 to 3 days, while an ablative area crusts and flakes over a few days. Gentle care and daily sun protection are advised.
Surface texture begins to smooth as the treated columns re-epithelialize, and the skin often feels tighter. Passes are spaced three to five weeks apart as remodeling builds between visits.
Across the course, pores look more refined and shallow scars soften as new collagen forms in the treated dermis. Deeper atrophic scars move gradually, and response speed varies by individual.
Remodeling continues after the series and deeper scars improve progressively; RE:BERRY will guide the interval and any maintenance that suits your skin and phototype.

Effects & Progress
Skin concerns rarely arrive alone. Enlarged pores, patchy tone, shallow scars, and coarse texture usually overlap across the same zones. The fractional families cover all of them, but not identically, so the physician grades every concern on imaging first and then chooses the family and density that weight the pass toward what matters most. That sorting step is the point of the whole taxonomy: naming the family before the machine keeps the pass aimed at your skin, not at a brand.
Depth is what actually distinguishes the fractional families in the room. Non-ablative settings sit shallow, refining pores and surface texture, while ablative columns and RF needles run deeper toward the floor of an atrophic scar, and the physician selects along that range zone by zone. A rolling scar and an icepick scar floor at different depths and take different families, so a graded, sorted pass outperforms one fixed intensity run across a whole face.
The reason fractional replaced full-field resurfacing is recovery, and the families differ here too. Treating only microscopic columns and sparing the healthy skin between them lets the surface repair in days where full-field work once took weeks. A non-ablative or RF microneedling pass typically settles within 1 to 3 days, so it fits a short Seoul stay; an ablative pass asks for a few days of crusting and is parked early in a trip, ideally over a weekend. The physician plans the recovery window around the dates you send, so downtime does not collide with your flight home.
Beyond resurfacing, the RF microneedling family adds a pairing the laser families do not. Its needles open micro-channels through the skin, and a collagen-supporting booster can be delivered into the treated dermis through them, so the two work together in one visit. Potenza carries a tip designed for exactly this. Whether a combination suits you depends on your concern and recovery window, so the physician sets the sequence and spacing at consultation. Every tip is genuine and officially imported, and the sealed cartridge is confirmed with you before it is opened.

What the Three Fractional Families Deliver โ and How the Result Builds
- One physiological principle, three tools: every fractional family works by treating microscopic columns and sparing the skin between them, so healing runs in days where a full-field laser once demanded weeks
- Ablative family (CO2, erbium YAG): vaporizes deeper columns and drives the strongest correction on atrophic acne scars, at the cost of a longer crusting window timed early in a Seoul trip
- Non-ablative family (pico, 1550nm): heats the dermis without breaking the surface, refining pores, tone, and fine texture with the shortest recovery, the family that suits a tight travel schedule
- RF microneedling family (Potenza): sends radiofrequency down insulated needles to a chosen depth, remodeling the dermis and opening micro-channels that can pair with a collagen-supporting booster
- Depth is the real dial: settings run from roughly half a millimetre for pores up to several millimetres for a scar floor, and the physician selects along that range zone by zone, never one fixed intensity
- Same physician from imaging through the pass to your two-week review: your fractional case in Gangnam is never handed to another practitioner mid-course, and every sealed tip is verified in front of you
| Timeline | What to Expect |
|---|---|
| Treated zones look flushed and feel warm; non-ablative and RF microneedling settle within one to three days, while an ablative area develops a fine crust that flakes over three to five days | |
| The surface re-epithelializes and texture begins to smooth; passes are typically spaced three to five weeks apart, so the next visit is planned around this point | |
| Pores look more refined and shallow scars soften as new collagen forms in the treated dermis; deeper atrophic scars move gradually across the course | |
| Remodeling continues after the series; a standard plan runs three to five sessions, with deeper scars sometimes needing more and a touch-up considered every six to twelve months |
The Three Fractional Families โ Sorting Ablative, Non-Ablative, and RF Microneedling
| Criteria | Ablative (CO2 / Erbium YAG) | Non-Ablative (Pico / 1550nm) | RF Microneedling (Potenza) |
|---|---|---|---|
| Energy type | Laser light that vaporizes tissue in the column | Laser light that heats without vaporizing the surface | Radiofrequency delivered down insulated needles |
| How it works | Deep columns are removed and the surface reforms | Thermal columns coagulate in the dermis, surface stays intact | RF heats the dermis at the needle depth chosen |
| Best suited for | Atrophic acne scars with a real floor, deep texture | Enlarged pores, uneven tone, fine surface texture | Scar remodeling plus booster pairing, dermal tightening |
| Recovery character | A crusting window of several days, timed early in a trip | One to three days of flush, the travel-friendly family | One to three days of flush; small needle marks settle |
| Pigment risk in Asian skin | Highest of the three; energy is dropped and PIH watched | Lower; often the safer opener for darker phototypes | Low to moderate; depth and passes tuned to phototype |
| Booster pairing | Not the usual pairing | Micro-channels can carry a booster after the pass | A dedicated tip is built for booster delivery |
| Sessions typically planned | A short course, spaced three to five weeks apart | Three to five sessions for a full result | A series, spaced to the depth and concern |
Why This Matters
The families are not ranked from weak to strong. They act on different physics: ablative light removes column tissue, non-ablative light coagulates it while sparing the surface, and RF microneedling heats through needles regardless of skin colour. A physician who treats the word "fractional" as one machine misses the point; the concern decides the family, and at RE:BERRY Gangnam many plans stage a non-ablative opener before a targeted ablative pass on the scars that need it.
Darker phototypes carry a genuine post-inflammatory pigment risk, so the family choice in Korea leans on phototype as much as on the concern. Non-ablative and RF passes at reduced energy are often the safer opening move for Fitzpatrick III-IV skin, with any ablative work staged carefully afterward under close pigment watch. This screening is a routine first step at RE:BERRY Gangnam, not an add-on.
KHIDI's 2025 international patient survey found 41.4% of respondents rank keeping the same doctor throughout as their leading criterion. At RE:BERRY the physician who grades your scars and sets the family runs every pass and reads your two-week review, so nothing about your energy settings is handed off between stages.

The Science That Splits Fractional Into Families
The whole category rests on one idea published in 2004: treat the skin in a grid of microscopic thermal columns and leave healthy skin between them, sparing the full surface. Manstein and colleagues named this fractional photothermolysis and showed that these microscopic treatment zones remodel the dermis while the untreated bridges around each column drive rapid repair. Every family branched from that principle, and recovery dropped from the weeks full-field ablation once required to days.
Manstein D, Herron GS, Sink RK, Tanner H, Anderson RR. Fractional photothermolysis: a new concept for cutaneous remodeling using microscopic patterns of thermal injury. Lasers Surg Med. 2004;34(5):426-438. doi:10.1002/lsm.20048
The reason the families diverge at all traces back to the physics of selective photothermolysis, described by Anderson and Parrish in 1983: a given wavelength and pulse duration deposit energy into a target with a matched absorption profile. Ablative wavelengths such as 10,600nm CO2 and 2940nm erbium are absorbed strongly by water and vaporize the column, while a non-ablative 1550nm beam coagulates the dermis without breaking the surface. RF microneedling steps outside the light model entirely, heating tissue by electrical resistance at the needle tip, so its pigment behaviour differs from the laser families.
Anderson RR, Parrish JA. Selective photothermolysis: precise microsurgery by selective absorption of pulsed radiation. Science. 1983;220(4596):524-527. doi:10.1126/science.6836297
Two clinical realities shape how a Seoul clinic applies these families. First, pigment: because ablative energy carries the highest post-inflammatory hyperpigmentation risk in Asian skin, guidance on managing hyperpigmentation informs the conservative energy settings and staged plans used for Fitzpatrick III-IV patients. Second, indication: much fractional work targets acne scarring, and the acne management literature frames scar prevention and correction within a broader treatment sequence, a reminder that a fractional pass is one tool inside a plan, not the plan itself. This is the reasoning the physician at RE:BERRY Gangnam applies when sorting a concern into the family that fits it.

Questions International Guests Ask About Fractional Laser in Korea
What actually makes a laser "fractional"?
A fractional laser splits its energy into a grid of microscopic columns and leaves the skin between those columns untouched. Manstein's 2004 work established that this pattern remodels the dermis while the intact bridges around each column heal the surface in days. The word describes the delivery pattern, not one specific machine, so several different devices all count as fractional.
How many types of fractional laser are there, and how are they grouped?
In practice they sort into three families. Ablative lasers (CO2 at 10,600nm, erbium YAG at 2940nm) vaporize the column for the strongest scar correction. Non-ablative lasers (pico and 1550nm) heat the dermis without breaking the surface, for pores and tone with short recovery. RF microneedling (Potenza) sends radiofrequency down needles to a chosen depth. At RE:BERRY Gangnam the physician grades your skin, then names the family.
Which fractional family is best for acne scars?
It depends on the scar. Atrophic scars with a defined floor, such as boxcar and rolling types, usually respond best to an ablative pass, because vaporizing deeper columns reaches the floor. Shallower scarring and rough texture often do well on a non-ablative or RF microneedling pass with far less downtime. Most scar plans in Gangnam grade each scar and mix families, never running one setting across the whole face.
How is non-ablative different from ablative fractional?
Ablative energy removes tissue in the column and the surface reforms over several days of crusting, giving the strongest correction. Non-ablative energy coagulates the dermis but leaves the surface intact, so recovery is one to three days of flush. The trade-off is straightforward: ablative reaches deeper at the cost of downtime, non-ablative is gentler and faster to heal. The physician weighs both against your travel window.
Is RF microneedling a kind of fractional laser?
It sits in the fractional family by principle but not by light. Potenza and similar devices deliver radiofrequency down insulated needles, not a laser beam, treating the dermis in a fractional pattern of channels. Because it heats by electrical resistance, its behaviour on darker skin differs from the laser families, one reason it is sometimes chosen for phototypes where pigment risk is a concern.
Does fractional laser work on darker or Asian skin?
Yes, with the energy and family chosen carefully. Darker phototypes carry a real post-inflammatory hyperpigmentation risk, so at RE:BERRY Gangnam the physician logs your Fitzpatrick type, drops the energy for Fitzpatrick III-IV skin, and often opens with a non-ablative or RF pass before any ablative work. Standardized-lighting photos track pigment across the course so any change is caught early.
How much downtime does each fractional family need?
The families differ sharply. A non-ablative pico or 1550nm pass usually settles within one to three days of mild redness. RF microneedling shows small needle marks that fade in a day or two. An ablative CO2 or erbium pass develops a fine crust that flakes over three to five days, with full barrier restoration around a week to ten days. The physician plans the recovery window around the dates you send.
How many fractional sessions will I need?
A standard plan runs three to five sessions spaced roughly four to six weeks apart, with deeper atrophic scars sometimes needing more. A maintenance touch-up is usually considered every six to twelve months. The exact count comes after your imaging and scar grading, since it depends on the concern, the family chosen, and how your skin responds between passes.
Can I combine fractional laser with a skin booster?
Often, yes. A fractional or microneedling pass opens micro-channels through the skin, and a collagen-supporting booster can be driven into the treated dermis through them. Potenza carries a tip designed for exactly this pairing. Whether it suits you depends on your concern and recovery window, so the sequence and spacing are set by the physician at consultation, not booked in advance.
How long is the consultation, and what happens in it?
The consultation is thorough. It includes a Fitzpatrick assessment, scar depth grading, and skin imaging so the physician can sort your concern into the right family. Nothing is treated on the spot without that reading. For international guests the whole assessment plus treatment usually fits inside a single visit once your slot is confirmed on WhatsApp.
Will fractional laser hurt?
A topical anaesthetic cream is applied beforehand and given time to take full effect, and chilled-air cooling runs alongside the pass, so most guests describe a warm prickling, not pain. Ablative passes feel stronger than non-ablative ones, which the numbing and cooling account for. The physician adjusts intensity to your feedback throughout the pass.
Where is the clinic, and how do I get there from Gangnam Station?
RE:BERRY occupies B1โB2 of KI Tower on Gangnam-daero, a 2-minute walk from Gangnam Station Exit 10 on Seoul Metro Line 2, roughly 45 to 60 minutes from Incheon Airport by AREX plus subway or by direct taxi. The clinic is open 10:00 to 20:00, 365 days a year, so a fractional appointment slots around Gangnam sightseeing and dining.
How do I book fractional laser in Gangnam as a foreign visitor?
Message RE:BERRY on WhatsApp with your concern, travel dates, and photos, and a coordinator replies in English within 24 hours to confirm a physician slot. The clinic is reservation-only for international guests, staff interpreters cover eight languages, and consultation plus the first pass usually fit into a single visit. A two-week multilingual safety call follows once you fly home.
Why choose RE:BERRY for fractional laser over other Gangnam clinics?
The difference is the sorting step. RE:BERRY grades your scars, pores, and phototype on imaging before naming a device, so the family is matched to your skin instead of to whatever machine is free. One physician runs the case from imaging through every pass to your two-week review, sealed tips are verified in front of you, and interpreters cover eight languages on-site.

Science Fractional resurfacing and the three energy families โ peer-reviewed references
The fractional category traces to a single concept: Manstein (2004) introduced fractional photothermolysis, treating skin in microscopic thermal columns while sparing the bridges between them so the surface heals in days. The families that grew from it, ablative, non-ablative, and RF microneedling, differ because of selective photothermolysis, the wavelength-and-target absorption principle Anderson and Parrish set out in 1983. Applied in Asian skin, the choice is disciplined by pigment risk, which is where hyperpigmentation management (Sarkar 2013) guides conservative energy in Fitzpatrick III-IV patients, and by indication, since acne scarring sits inside a broader treatment sequence framed by the acne management guidelines (Zaenglein 2016).
