Derma Roller · RF Microneedling · Pacific Plaza
Microneedling vs RF microneedling is really a comparison of two different injuries. A home derma roller or pen makes shallow punctures at a depth and pressure you cannot see; RF microneedling, done in clinic, uses insulated needles to place radiofrequency heat at a depth Dr Sin Yong sets for each zone. This page is for anyone weighing a home device against clinic treatment for scars, pores or texture.
Home microneedling. A derma roller is a drum of fine needles rolled across the skin; a microneedling pen stamps needles in and out. Each puncture is a tiny wound that heals like any other. How deep it goes depends on how hard you press, the angle you hold it at and how many times you pass over the same spot, so the depth changes from one stroke to the next. Because a drum's needles enter and leave at an angle, they can tear the channel rather than make a clean hole, and pressing hard leaves tram-track marks.
RF microneedling. Here the needle is only the route in. RF microneedling passes insulated needles straight down to a chosen depth and releases radiofrequency current from the bare tips. That heats a small column of dermis while the surface the needle crossed is largely spared. Depths of around half a millimetre treat surface texture; two millimetres or more reach the level where scar tethering and dermal thinning sit. It is the heat at depth, not the puncture, that drives collagen remodelling.
Side By Side
The table compares a home roller or pen with RF microneedling as it is done at Atelier.
| Home roller or pen | RF microneedling | |
|---|---|---|
| Energy or mechanism | Mechanical punctures only | Radiofrequency heat released at insulated needle tips |
| Depth or target | Shallow and uneven; varies with pressure and angle | Set per zone by a doctor, from texture depth to the level of scar tethering |
| Typical sessions | No medical schedule; set by the user | Usually three to four, four to six weeks apart |
| Comfort and numbing | Usually none | Numbing cream for around half an hour beforehand |
| Downtime | Depends on pressure and needle; irritation and pinpoint marks | Red, warm and tight for one to three days |
| When results show | Not a dependable change in scar depth | Gradually over eight to twelve weeks; judged about three months after the last session |
| Who it suits | At most, how the surface feels | Rolling and shallow boxcar scars, enlarged-looking pores, early laxity, in suitable skin |
| At Atelier | Not offered at Atelier | Offered at Atelier |
At Home
A roller is sterile only the first time it is used. Wiping it with alcohol does not sterilise a used drum, and blunt or bent needles tear rather than puncture. Rolling over skin with bacteria on it can carry them across the face. Serums, fragrances and acids made for intact skin travel down the channels and can cause irritation or granulomas, which are firm inflammatory lumps. Cold sores around the mouth can be reactivated.
In Asian skin the most specific risk is pigment. Repeated irritation triggers post-inflammatory hyperpigmentation, and those brown patches may persist much longer than the texture problem that prompted the needling.
Do not microneedle at home if you have active acne, folliculitis or infection in the area; a history of cold sores there; eczema, rosacea or perioral dermatitis, especially during a flare; a tendency to keloid or raised scars; recent isotretinoin, or a medicine that affects bleeding or healing; or skin that has darkened after irritation, a peel or a laser. Never share a roller.
Which Problem
Acne scars. No home needle reaches the base of a rolling, boxcar or ice-pick scar. Tethered scars need the band cut with subcision, ice-pick tracts need TCA CROSS, and rolling scars need heat at depth; how RF microneedling fits that plan is on RF microneedling for acne scars. A 2026 analysis of trials found both fractional CO2 laser and RF microneedling effective for atrophic acne scars, and 2024 evidence-based guidance puts scar type and depth at the centre of the treatment order.
Pores and texture. Pore size is largely set by genetics; what changes is the collagen around the opening and the shadow it casts, as uneven skin texture and large pores explains. Collagen at that depth responds to heat, not to a shallow puncture.
Surface feel. The most home rolling can do is change how the surface feels for a while. It can also add pigment and new marks to skin that is already scarred.
How Atelier Decides
Dr Sin Yong starts with the skin, not the device. Scars are graded under angled light and the skin is stretched to see which dips soften and which stay pinned, then depth is mapped across the face. Tethered scars go to subcision, ice-pick scars to TCA CROSS, superficial scars may suit the FSX Laser, and deeper scars go to fractional CO2 or RF microneedling, with needle type and energy chosen for your skin type. Whether any treatment is needed at all is part of the same assessment.
After RF microneedling, the skin is kept clean and cool, with a bland moisturiser, no make-up until the surface has closed, daily sunscreen and no active products until your follow-up.
