Sylfirm X: RF microneedling for the full skin layer.
Dual-wave bipolar RF microneedling with non-insulated “NA-effect” electrodes treating the full skin layer at 0.3–4.0 mm depths — pulsed and continuous modes on one handpiece, for licensed providers and practice owners.
- Modality
- Dual-wave bipolar RF microneedling — four pulsed and four continuous settings on one handpiece
- Manufacturer
- Viol, distributed by BENEV. Eventide is a United States distributor, not the manufacturer.
- Regulatory
- Sylfirm X holds two FDA 510(k) clearances — K200185 (22 April 2020) and K213612 (23 June 2022), both to VIOL Co., Ltd. under product code GEI — each covering electrocoagulation and hemostasis. Treatments listed describe how licensed providers use the platform, not cleared indications.
- What it costs
- Quoted, not listed: configuration and term move the number, and consumable tips are budgeted separately.
Two treatment menus, one handpiece — and one paperwork question
The argument for this platform is that PW and CW give you a vascular-and-pigment menu and a collagen-and-tightening menu without buying two consoles. The argument to settle before you sign is which regulatory document actually applies to the unit you receive.
one handpiece, two menus — pigment and vessels on PW, collagen and tightening on CW.
Practices that want depth control and two modes
- You want redness, rosacea, melasma and small vessels on one setting family, and revitalization, collagen and laxity on the other.
- You want depth set per pass: 300 to 4,000 µm, including the 300-micron flagship depth for the epidermis and basement membrane.
- You read literature before you buy — the manufacturer counts 26+ clinical papers across 16 universities and hospitals.
- You treat curved or narrow anatomy and want the XE tip's perimeter-removed geometry for overlap work.
Where the paperwork and the literature stop
- What the record covers is narrower than the practice use: both Sylfirm X clearances (K200185 and K213612) are for electrocoagulation and hemostasis. A clearance for electrocoagulation is not permission to advertise resurfacing, tightening or vascular and pigmentary indications.
- There are two clearances in play, not two kinds of document. FDA's 510(k) database lists K200185 (2020) and K213612 (2022) for the same device and applicant; the US distributor typically cites the later one. Ask which letter governs the configuration you are quoted, and get it in writing with the quote.
- Consumable tips are the ongoing cost on any RF microneedling platform, and they are budgeted separately from the platform.
- Much of the published record is in animal, cellular or small-cohort work. Published studies are literature about the technology, not a claim of outcome for any patient.
It stays on shortlists because one dual-wave handpiece covers pulsed and continuous work that used to need two platforms, and because the paperwork question is closed by one request: the current regulatory letter, with the quote.
Four questions worth asking us
- Which regulatory letter is current for the unit I would receive, and what does it actually cover?
- What does a Standard tip cost against an XE tip, and how many will I use in a month?
- What is the current warranty term, and what does service cost after it?
- What does the monthly look like once consumable tips are in the model?
Eight settings and two tip geometries on one handpiece
Sylfirm X is a bipolar RF microneedling platform built around the NA Effect — an independent coagulation around each electrode rather than a bridge between electrode pairs. Four pulsed-wave settings, four continuous-wave settings and two consumable tip geometries share the same handpiece; depth is adjustable from 300 to 4,000 µm across the range. Uses below describe provider practice, not cleared indications.

Why non-insulated electrodes change the tissue reaction
The NA Effect is the mechanism the whole platform is built on, and it is what the two waveforms are two applications of.
- Independent coagulation per electrode
- With non-insulated electrodes, coagulation initiates at the end of each electrode and forms around it independently before any coagulation appears between the bipolar pair. Insulated systems coagulate only in a partial dermal layer.
- Total dermal layer, one penetration
- Because coagulation continues from the deeper dermis to the upper dermis on a single pass, the treated column is continuous rather than segmented — with no noticeable thermal damage recorded in the epidermis.
- PW mode: the vascular and pigment route
- Multiple short pulses create soft, selective coagulation in the basal layer and upper dermis, targeting the basement membrane and abnormal small vessels with limited effect on surrounding tissue.
- CW mode: the revitalization route
- A single long pulse creates wide independent coagulation around each electrode through the full dermal layer, aimed at collagen and elastin fiber density.
26+ papers across 16 institutions, and one regulatory question
Sylfirm X has the deepest published literature of any platform in this catalog. A representative selection, with study design stated so you can judge relevance — and the regulatory record read for what it is rather than what it is often taken for.
| Source | What it says | What it does not establish |
|---|---|---|
| Regulatory record | FDA's 510(k) database lists two clearances for Sylfirm X (VIOL Co., Ltd.), both under product code GEI: K200185, decided substantially equivalent 22 April 2020, and K213612, decided substantially equivalent 23 June 2022. Both cover electrocoagulation and hemostasis. | A clearance for electrocoagulation and hemostasis is not a cleared indication for resurfacing, tightening or vascular and pigmentary work, and the clearance the distributor cites is for electrocoagulation and hemostasis rather than for any aesthetic treatment. Neither document tells you what you may advertise — ask for the current regulatory letter with your quote. |

The manufacturer counts 26+ clinical papers across 16 universities and hospitals; the rows above are a representative selection with study design stated so you can judge relevance. The NA Effect and short-pulse RF designs are patented by Jongju Na, MD, PhD (US Patent 9480836). FDA lists two 510(k) clearances for this device, K200185 (2020) and K213612 (2022), both for electrocoagulation and hemostasis — ask which letter governs your configuration and get it in writing with the quote.
Published studies are literature about the technology, not a claim of outcome for any patient. What it does give you is an unusually deep published literature for an RF microneedling platform, with a named inventor and a patent number attached — enough for a clinical lead to judge relevance rather than take a rep’s word for it.
What it costs to buy, and what it costs to run
A laser that sits idle loses money. The support around the device is what turns capital into revenue — handled by the same team that sources your pharmacy and biologics.
I sell the install and the training as hard as the platform. An idle device is the only bad outcome here.
- Price and financing
- Platforms like this do not carry a sticker price. Configuration, applicators, training and term all move the number, so the question that actually matters is the monthly. Most device financing here lands near $2,500 per month, pending configuration, credit approval, rates and terms. Tell us which treatments you want on the menu and we work the number back from the revenue they carry. Weighing the options? Read Buy vs. lease your first laser.
- Consumable tips
- Budget separately for consumable tips, which are the ongoing cost on any RF microneedling platform.
- Installation and site prep
- Voltage, footprint, and installation handled — full-range 110–220V platforms fit most rooms. Site prep, voltage and footprint checks are handled before delivery.
- Clinical training
- Hands-on protocols and KOL-backed education so staff are treating confidently from day one.
- Warranty and service
- Warranty and service terms are set by the manufacturer and vary by platform — the current terms are included in every quote. Eventide remains your single point of contact after installation.
- Who makes it, who sells it
- Sylfirm X is manufactured by Viol. Eventide Aesthetics & Wellness is a United States distributor supplying it to licensed providers and practice owners — we handle the quote, the financing, the install and the training, and we stay your point of contact after the sale.
- Who it is sold to
- This is a business-to-business page. Sylfirm X is sold to licensed medical providers and the practices they operate, not to consumers, and nothing here is directed at patients. We support clinics in all 50 US states.

What is the Sylfirm X's regulatory status?
Sylfirm X holds two FDA 510(k) clearances — K200185, cleared 22 April 2020, and K213612, cleared 23 June 2022 — both issued to VIOL Co., Ltd. under product code GEI (electrosurgical cutting and coagulation, 21 CFR 878.4400), each covering electrocoagulation and hemostasis. Treatments listed on this page describe how licensed providers use the platform, not cleared indications.
How much does a Sylfirm X cost?
Sylfirm X pricing depends on configuration and whether you buy, lease or rent, so we quote it rather than list it. Budget separately for consumable tips, which are the ongoing cost on any RF microneedling platform. Most practices ask for the monthly rather than the sticker, and device financing here typically lands near $2,500 per month, pending configuration, credit approval, rates and terms.
What is the difference between PW and CW mode on Sylfirm X?
PW (pulsed wave) fires multiple short pulses for soft, selective coagulation in the basal layer and upper dermis, aimed at the basement membrane and abnormal small vessels. CW (continuous wave) fires a single long pulse for wide coagulation through the total dermal layer, aimed at collagen and elastin. There are four settings in each family.
How deep does Sylfirm X treat?
Needle depth is adjustable from 300 to 4,000 µm (0.3–4.0 mm), set per pass by the provider. Both the Standard and XE tips are 5×5 arrays of 25 pins at 2 mm intervals.
