Pulsed Wave · Insulated Tips · Pacific Plaza
Sylfirm X vs RF microneedling is not a choice between two treatments: Sylfirm X is one RF microneedling device, and what sets it apart is a pulsed-wave mode that has been studied in melasma and redness-prone pigment. This page explains what that mode does, what the evidence shows so far, and how Dr Sin Yong plans RF microneedling at Atelier, where Sylfirm X is not offered.
Every RF microneedling system drives fine needles into the dermis and passes radiofrequency through them. The heat forms small zones of coagulation, and the skin repairs them with new collagen and elastin over several months. Devices differ in engineering: insulation, depth range, frequency and energy timing.
Sylfirm X, made by Viol in Korea, is a bipolar device at 2 MHz with non-insulated needles. Its US filing lists four continuous-wave and four pulsed-wave modes and a needle depth of 0.3 to 4.0 mm, adjustable in 0.1 mm steps. Continuous-wave mode behaves like conventional RF microneedling. Pulsed-wave mode releases the energy in very short repeated bursts.
RF microneedling at Atelier uses insulated needles that release bipolar radiofrequency only at their tips, so heat builds in the dermis while the pigment-bearing surface is largely spared. Depth is set zone by zone, around half a millimetre for texture and two millimetres or more for scar tethering and dermal thinning. Full detail is on the RF microneedling page.
The Pulsed Mode
Laboratory work on pulsed bipolar radiofrequency through non-insulated needles found small coagulation zones in the dermis, a thickened basement membrane (the layer between epidermis and dermis) and narrowed small blood vessels whose lining was left intact. Those effects are why pulsed mode is discussed for melasma, Riehl melanosis and pigment alongside redness.
The main clinical paper is a Korean series of 44 patients with melasma or Riehl melanosis that had not responded to other treatment. After pulsed-mode sessions, most improved, measured melanin, redness and water loss through the skin fell, and no serious adverse events were reported. It had no control group, so it cannot separate the device from sun protection, topical treatment or time. It is encouraging, not settled.
Melasma itself is chronic, driven by sunlight, visible light, heat, hormones and blood-vessel signals; the melasma condition guide explains why it returns. Aggressive heat is what tends to worsen it, and that is a settings decision on any device.
Side By Side
The Sylfirm X column describes the device as its makers and published papers do; the Atelier column follows Atelier's own pages.
| Sylfirm X | RF microneedling at Atelier | |
|---|---|---|
| Energy or mechanism | Bipolar 2 MHz radiofrequency through non-insulated needles; continuous-wave and pulsed-wave modes | Bipolar radiofrequency released at insulated needle tips; continuous delivery, depths stacked in one session |
| Depth/target | 0.3 to 4.0 mm in 0.1 mm steps; pulsed mode aimed at the basement membrane and small vessels | Dermis: about 0.5 mm for texture, 2 mm or more for scar tethering and thinning |
| Typical sessions | Set by the treating clinic | Often three to four, four to six weeks apart, for texture and scars |
| Comfort and numbing | Set by the treating clinic | Topical anaesthetic for about 30 minutes; warmth and pressure |
| Downtime | Redness and pinpoint marks that vary with mode and settings | Redness and a sunburnt feel for one to three days |
| When results show | Gradually, as collagen remodels; pigment change judged over a course | Over eight to twelve weeks per session; a course is judged about three months after the last |
| Who it suits | Continuous mode: scars, pores, texture; pulsed mode studied in hard-to-treat melasma and Riehl melanosis | Rolling (once released) and shallow boxcar scars, texture, pores, early dermal laxity |
| At Atelier | Not offered at Atelier | Offered at Atelier |
Which Problem
How Atelier Decides
Dr SY examines the skin before any device is discussed: scar type and tethering, skin type and pigment history, and any melasma or redness. Where melasma and scars coexist, the pigment is usually settled and managed first, then scar work starts with insulated needles, conservative energy and strict sun protection.
Insulation matters most in skin that darkens easily. Non-insulated needles heat along the whole track, including the surface, which suits broad, shallow texture work once pigment risk has been weighed; insulated needles keep heat at the tip. Atelier uses insulated needles.
Wherever you are treated, ask what type of scar or pigment you have, whether the needles are insulated and why, whether anything is planned first, and who sees you if the skin darkens. A deadline is never a reason to proceed. Who suits the treatment is on RF microneedling suitability.
