Quick answer
- Sylfirm X is an RF microneedling device made by Viol in Korea. It is known for offering two kinds of RF pulse: a continuous-wave mode like other RF microneedling, and a pulsed-wave mode of very short pulses that the maker promotes for redness and pigment-prone skin.
- It is marketed for melasma, redness, enlarged pores, acne scars and texture. As with other RF microneedling, published evidence is mostly small studies, and the operator and settings matter as much as the brand.
- A course is usually several sessions about four weeks apart, with redness and mild swelling for one to three days after each.
- SkinRev Lab does not use Sylfirm X. Dr Sin Yong performs RF microneedling on the Secret RF system (insulated needles, adjustable depth), priced at consultation.
Key facts
Sylfirm X at a glance
- Maker: Viol in Korea.
- Needles: bipolar, non-insulated, 25-pin tip
- Depth: adjustable, about 0.3 to 4 mm (maker's brochure)
- Modes: pulsed wave (PW) and continuous wave (CW)
- At SkinRev Lab: not used; RF microneedling is done on Secret RF by Dr Sin Yong.
How it works
How Sylfirm X works
RF microneedling passes fine needles into the skin to a set depth and releases radiofrequency energy around the needle tips. The heat creates small zones of controlled injury in the dermis, surrounded by untouched skin, and collagen is remodelled over the following months. It is known for offering two kinds of RF pulse: a continuous-wave mode like other RF microneedling, and a pulsed-wave mode of very short pulses that the maker promotes for redness and pigment-prone skin.
Insulated needles release heat mainly at the tip, which spares the surface and is often preferred for skin that darkens easily; non-insulated needles heat along the whole shaft. Depth, energy, the number of passes and how the skin is cooled all change the result and the downtime.
Compared
Sylfirm X vs other RF microneedling devices
| Device | Maker | How it delivers RF | At SkinRev Lab |
|---|---|---|---|
| Secret RF | ilooda, Korea | Bipolar RF, insulated needle options, depth about 0.5 to 3.5 mm | Used by Dr Sin Yong |
| Sylfirm X | Viol, Korea | Bipolar RF via non-insulated needles; pulsed-wave and continuous-wave modes | Not used |
| Potenza | Jeisys, sold by Cynosure | Monopolar and bipolar RF at 1 and 2 MHz; several tips | Not used |
| Morpheus8 | InMode | Fractional RF with coated needles; deeper body tip | Not used |
This comparison is drawn from each maker's published information and is for explanation only. A device name alone does not tell you the depth, energy or number of passes a clinic will use, so ask about those.
Sessions and recovery
Sessions, downtime and who should wait
- Sessions: commonly three to five, about four weeks apart; scars may need more.
- Downtime: redness, mild swelling and fine grid marks for one to three days; makeup usually after 24 hours.
- Risks: temporary redness, swelling, pinpoint bleeding, dark marks in skin that pigments easily and, rarely, infection or scarring.
- Wait or avoid: pregnancy, active infection or acne flare in the area, recent isotretinoin, keloid tendency, pacemakers or metal implants in the area; tell the doctor about blood thinners.

Common questions
Your questions,
answered
What is Sylfirm X?
Sylfirm X is a radiofrequency microneedling device made by Viol in Korea. Fine needles carry RF heat into the dermis to remodel collagen for texture, pores, scars and fine lines.
Is Sylfirm X good for melasma?
Its pulsed-wave mode is promoted for melasma and redness, and small studies have reported improvement, but melasma relapses easily and needs sun protection and creams alongside any device. At SkinRev Lab, Dr Sin Yong treats melasma with creams, tranexamic acid where suitable and gentle lasers such as Laser Toning.
What is the difference between pulsed-wave and continuous-wave RF?
Continuous-wave mode delivers one longer pulse to heat the dermis and remodel collagen. Pulsed-wave mode delivers several very short pulses that the maker says act more on small blood vessels near the surface, for redness and pigment-prone skin.
Does SkinRev Lab offer Sylfirm X?
No. SkinRev Lab does not use Sylfirm X. Dr Sin Yong performs RF microneedling on the Secret RF system at CityLink Mall, priced at consultation.
How many Sylfirm X sessions are needed?
Commonly three to five sessions about four weeks apart, with more for scars. The number depends on the concern and is set at consultation.
What is the downtime after Sylfirm X?
Usually one to three days of redness, mild swelling and faint grid marks. Deeper settings take longer to settle.
How much does Sylfirm X cost in Singapore?
SkinRev Lab does not offer Sylfirm X, so we do not set a price for it. Prices vary by clinic, treatment area and number of sessions; for the RF microneedling and lasers Dr Sin Yong uses, the cost is given at consultation after he has assessed your skin.
