Sylfirm X RF Microneedling


What is Sylfirm X?
Sylfirm X is a radiofrequency microneedling system made by Viol in South Korea. Like other microneedling devices it uses fine needles to create controlled micro-injuries that prompt the skin to rebuild collagen. The difference sits in its pulsed-wave mode, which lets it work on pigment and blood-vessel problems that most microneedling leaves untouched.
That second job is the reason Dr Garara reaches for it. Melasma, post-inflammatory pigmentation and stubborn facial redness are some of the hardest concerns to treat well, especially in richer skin tones, and Sylfirm X was designed around exactly that gap. The needles are non-insulated and energy can be delivered as shallow as 0.3 mm, so it also suits delicate areas such as the under-eyes.
Two energy modes do two different jobs. Pulsed-wave mode delivers short, repeated bursts of RF aimed at the abnormal vessels and basement membrane beneath melasma, cooling between pulses to avoid the heat load that provokes rebound pigmentation. Continuous-wave mode heats the deeper dermis to remodel collagen for laxity, scarring and texture.

How it works
Pulsed wave (PW) mode: short, repeated bursts of RF aimed at the abnormal vessels and damaged basement membrane beneath melasma, with cooling between pulses to avoid sustained heat.
Continuous wave (CW) mode: steady RF that heats the deeper dermis to remodel collagen and elastin — the setting used for laxity, scarring and texture.
Region Selective Treatment (RP): Viol's repeated ultra-short pulse method acts mainly on abnormal tissue and spares healthy structures, underpinning its use on vascular and pigmented lesions.
Adjustable depth: needle depth from 0.3 mm to 4 mm treats thin under-eye skin and deeper scars by changing settings.
The benefits
Targets pigment most microneedling cannot: the pulsed mode treats melasma and vascular pigmentation directly, not just texture.
A gentler heat profile for melasma: brief, controlled pulses reduce the thermal load that tends to make pigment worse.
Works on redness and rosacea by targeting abnormal vessels behind persistent facial redness.
Collagen for laxity, scars and pores through the continuous mode.
Comfortable on delicate areas thanks to non-insulated needles and controlled energy.
One device, many concerns — pigment, redness, texture and tightening in a single tailored plan.
Concerns it treats
What to expect
Before
Consultation and skin assessment. Numbing cream is applied for around 30 minutes.
During
A handpiece passes over the skin delivering RF through the microneedles. Most people describe heat and mild prickling. A session runs 30 to 60 minutes.
Immediately after
Redness and a sandpaper texture, sometimes mild swelling. Makeup is usually avoided for 24 hours.
Downtime
Most redness settles within one to three days.
Results
Texture and tone improve over several weeks as new collagen forms. Pigment changes build across the course.
Course
Commonly three sessions about four weeks apart, then maintenance as needed.
What the evidence shows
Melasma
- In a single-blinded pilot study, non-insulated microneedle RF using the Sylfirm device improved melasma, and adding polynucleotides improved the result further (PMC9209614).
- A randomised controlled trial of Sylfirm X for melasma is under way, comparing treatment plus sunscreen against sunscreen alone (ClinicalTrials.gov, NCT06415435).
- Radiofrequency microneedling for melasma is also being studied specifically in skin of colour, where the need is greatest.
Manufacturer data
- Viol reports roughly a 20 to 30 percent reduction in pigmentation and a 20 to 25 percent reduction in pore size after a single session. These are manufacturer figures and individual results vary.
A note on skin of colour
- Melasma and post-inflammatory pigmentation fall disproportionately on Fitzpatrick IV to VI skin, and lasers used for pigment can make both worse by overheating melanocytes. Sylfirm X's pulsed mode runs at low, controlled energy and targets the vasculature and basement membrane rather than blasting pigment, which lowers the risk of rebound darkening. Settings are still tailored, and a conservative approach with a test response is standard.
Individual results vary and depend on assessment at consultation. Manufacturer figures are attributed as such.
Key facts
- Sylfirm X is a radiofrequency microneedling device made by Viol in South Korea.
- Its pulsed-wave mode treats pigment and vascular concerns such as melasma and rosacea, unlike standard microneedling.
- Needle depth is adjustable from 0.3 mm to 4 mm.
- It is one of the few RF microneedling devices well suited to melasma in skin of colour.
- Treatment is usually a course of about three sessions, four weeks apart, with 1 to 3 days of redness.

Find answers to common questions about Sylfirm X.
Yes. Its pulsed mode uses low, controlled energy that targets vessels and pigment-related structures rather than bulk-heating the skin, which makes it one of the more suitable RF microneedling options for Fitzpatrick IV to VI. Settings are still adjusted for each person.
Melasma is its signature use. The pulsed mode acts on the abnormal vessels and basement membrane linked to melasma while limiting the heat that can trigger rebound pigmentation.
Most plans involve around three sessions spaced about four weeks apart. Pigment and scarring may need more, and some people add occasional maintenance.
Numbing cream is applied first. Most people feel heat and a prickling sensation rather than sharp pain.
Expect redness and a rough texture for 24 to 72 hours, sometimes with mild swelling. Most people return to normal activity quickly.
Tone and texture improve over several weeks as collagen rebuilds. Pigment results build gradually across the course rather than appearing overnight.
Standard devices mainly remodel collagen with heat. Sylfirm X adds a pulsed mode that also treats pigment and vascular concerns, which ordinary microneedling does not.
