Sylfirm X
The Sylfirm X handpiece is held against the skin for each placement. It can run in two modes, one for pigment and vessels and one for firming.

Sylfirm X vs Morpheus8
Sylfirm X is the shallower of the two. Both devices put tiny needles into the skin and send radiofrequency energy out of the needle tips, and Sylfirm X can be set as fine as 0.3 mm. Morpheus8 is the deeper one. Its larger tips reach 7 mm, so it is used on the jawline, under the chin and on the body. Neither device has a published trial of its own.
At a glance

Morpheus8
The Morpheus8 tip up close. The gold pins are what carry the radiofrequency energy below the surface — the needles are the delivery route, not the treatment itself.
Side by side
The differences that matter
What it is
Sylfirm X
Bipolar RF microneedling, 2 MHz
A Korean-made device with two energy modes, one continuous and one pulsed. Tips come with 25 or 18 electrodes. The claim that the pulsed mode suits redness and pigment is a marketing claim, not a tested one.
Morpheus8
Bipolar RF microneedling, 1 MHz
A rebuilt version of an older device called Fractora. It runs 12-, 24- and 40-pin tips. It can release energy at several depths in one pass as the needle pulls back out.
How deep it goes
Sylfirm X
0.3 to 4.0 mm, in 0.1 mm steps
The 0.3 mm setting is the shallowest in this device class. Pigment sits in and just under the top layer of skin. That shallow end is what this device is sold on.
Morpheus8
Up to 4.0 mm or 7.0 mm, by tip
The 12-pin tip reaches 4.0 mm. The 24- and 40-pin tips reach 7.0 mm. The deep end is what Morpheus8 is sold on.
The needles
Sylfirm X
Not insulated, says the maker
A bare needle shaft carries current at the surface as well as deeper down. That is the reason a mark can be left at each entry point.
Morpheus8
Insulated except the last 0.5 mm
The pins are coated along the shaft, so the energy lands mostly at the tip.
What the evidence shows
Sylfirm X
No Sylfirm X trial was found
The melasma research clinics point to used other machines. It should not be credited to this device.
Morpheus8
No randomised trial was found

The at-home or drugstore version
Sylfirm X
Home wands are far weaker
A home radiofrequency wand puts a fraction of the power into the skin surface. It has no needles, so nothing carries energy down to the depth this device works at.
Morpheus8
Home rollers are a different thing
A home derma roller has needles but no radiofrequency, so nothing heats the skin under the surface. Its needles are shorter and blunt quickly, and a blunt needle does more damage.
Who tends to be happy with it
Sylfirm X
- Best for — Someone whose main concern is at the surface, and whose provider wants a very shallow setting.
- The mindset — Shallow and repeated, with no device-specific evidence to lean on.
Morpheus8
- Best for — Someone whose provider wants to work deep, on the jawline, under the chin or on the body.
- The mindset — Depth and contour rather than pigment.
Where the pigment claim stands
Sylfirm X
Sylfirm X's two modes are documented. What they treat is not. The paperwork records both modes. It does not record the claim that the pulsed mode suits redness, melasma and other pigment problems.
No trial of Sylfirm X itself has been published. The melasma research on this treatment did not use this machine. The one study that named a device used a different one, and it found no clear effect.
The fine print
Sylfirm X
Sylfirm X is made by VIOL in Korea and sold in the US by Benev. Its pulsed setting runs 120 to 240 milliseconds and its continuous mode 120 to 300 milliseconds. Its 510(k) predicate devices are CELFIRM and Scarlet SRF, both from the same manufacturer, so these machines are more closely related than the marketing suggests. The FDA summary does not state whether the needles are insulated.
Morpheus8
Morpheus8 is InMode's device, built on the Fractora platform first cleared in 2011. Its operator manual describes energy released at 7, 5 and 3 mm as the needle retracts, and states that the pins are coated except for the distal 0.5 mm.

Common questions
Questions Patients Ask
Is Sylfirm X FDA cleared for melasma?
No. Its cleared indication is "for use in dermatologic procedures for electrocoagulation and hemostasis." Melasma, pigment, redness and vascular lesions appear nowhere in it. Its 2022 clearance actually narrowed the wording rather than adding to it. Using it for melasma is off-label, which is legal and routine.
Is the pulsed-wave mode real, or marketing?
The mode is real and documented: the FDA summary lists pulsed settings of 120 to 240 milliseconds delivered as four pulses, alongside continuous settings of 120 to 300 milliseconds. What is marketing is the claim about what that mode treats.
Which one goes deeper?
Morpheus8. Sylfirm X runs 0.3 to 4.0 mm. Morpheus8's FDA summaries list up to 4.0 mm on the 12-pin tip and 7.0 mm on the 24- and 40-pin tips. Sylfirm X goes shallower, though: 0.3 mm is the lowest minimum documented in this class.
Which is safer for darker skin?
Neither has been tested against the other. Both heat by electrical resistance rather than by targeting pigment, which is the class advantage over ablative lasers. Sylfirm X's clearance sets no skin type limit; Morpheus8's restricts energies above 62 mJ per pin to types I to IV. Energy, density and operator technique matter more than the brand.
Are there studies on Sylfirm X specifically?
None were found. The melasma studies clinics cite are device-agnostic or used other machines, and should not be attributed to Sylfirm X. Morpheus8 is barely better off: no randomised controlled trial of it was found either.
Could either make my melasma worse?
Nobody can promise it will not. Pigment change is the second most reported complication in FDA post-market data for this device class, and there is no trial of Sylfirm X itself. The one published study that tracked melasma severity for six months after RF microneedling found it unchanged — that is reassuring but small (20 patients) and not device-specific. Ask for a test area, keep energy conservative, and use daily sunscreen throughout the course.
How many sessions, and how long do results last?
Published protocols for the class cluster at three sessions three to eight weeks apart, but that is copied convention rather than a tested dose. Six months is the longest properly measured follow-up anywhere in this literature.
Safety to keep in mind
RF microneedling can cause serious injury. The FDA has received reports of burns, scarring, loss of fat, nerve damage and disfigurement. Some injuries have needed surgery or other medical treatment. A few days of expected redness is not the full risk picture.
Choose a licensed medical professional trained on the device. Discuss the risks and other treatment options before deciding. RF microneedling should not be done at home.
