Sylfirm X in Seoul: Dual-Wave RF Microneedling for Melasma
The short answer
Sylfirm X is a dual-wave RF microneedling device that uses pulsed energy for melasma and redness and continuous energy for scars, pores and tightening. In Gangnam a full-face session typically costs ₩200,000–₩700,000, takes about 30 minutes after numbing, and leaves redness for one to three days. Most plans involve three to five sessions roughly four weeks apart.

What makes Sylfirm X different
Most RF microneedling devices deliver energy in one way. Sylfirm X, developed in Korea, offers two modes. Pulsed wave (PW) delivers short bursts of energy that target abnormal blood vessels in the upper dermis, which is why it is used for melasma and redness. Continuous wave (CW) delivers steady energy for collagen remodelling, suitable for scars, pores and tightening.
Being able to switch between modes, or combine them, lets the doctor tailor treatment to skin that has more than one concern.
Why it is used for melasma
Melasma is not only a pigment problem. Research suggests that changes in the upper dermis, including fragile blood vessels and damaged basement membrane, help keep it active. Sylfirm X's pulsed mode targets these structures with low heat, which may help pigment respond to treatment and reduce rebound. It is often combined with laser toning and prescription care. See our melasma treatment page for the wider approach.
Other uses
- Persistent facial redness and visible vessels
- Rolling and shallow acne scars
- Enlarged pores and rough texture
- Mild laxity and fine lines
| Concern | Usual mode | Typical sessions |
|---|---|---|
| Melasma | Pulsed wave | 3–5 |
| Redness | Pulsed wave | 3–4 |
| Acne scars | Continuous wave | 3–5 |
| Pores and texture | Continuous or combined | 3 |
What a session is like
After cleansing, numbing cream is applied for 30–40 minutes. The doctor then passes the handpiece over the face in sections. You will feel pressure and some heat. The procedure itself takes about 20–30 minutes. A calming mask or LED usually follows, and some clinics add exosomes or growth-factor serum.
Downtime
Expect redness and tiny pinpoint marks for one to three days, longer with higher continuous-wave settings. Most people can wear light makeup after 24 hours. Pulsed-wave melasma sessions tend to have less downtime than scar settings.
Results
Redness often looks calmer after the first session. Melasma and scars improve gradually over a series, with the main change after three to five sessions spaced about four weeks apart. Because melasma is chronic, maintenance and strict sun protection remain important.
How it compares with other RF microneedling
Devices such as Potenza and Morpheus8 focus mainly on collagen remodelling. Sylfirm X's pulsed mode is what sets it apart for pigment and vascular concerns. If scars or tightening are your only goals, our RF microneedling and Morpheus8 pages explain alternatives.
Aftercare
- Avoid makeup for 24 hours and actives for about a week
- Use a calming moisturiser and SPF 50 daily
- Avoid saunas, alcohol and intense exercise for two days
