SYLfirm X.
Address pigment, redness, scars, texture, and laxity in one device — with Sylfirm X RF microneedling. Pigment-safe across all skin tones, FDA-cleared, gold-tip needles, conservative protocol design.
RF energy, precisely placed.
Sylfirm X is a radiofrequency microneedling device by Viol (Korea), FDA-cleared in the United States. It pairs gold-tip insulated needles with two distinct RF energy modes — Pulsed Wave (PW) and Continuous Wave (CW) — to address pigment, redness, scars, texture, pores, and mild laxity in one device.
The needles create controlled micro-channels in the skin while delivering RF energy at a precise dermal depth. The micro-channels stimulate the skin's wound-healing response; the RF triggers collagen remodeling underneath. The two effects together produce more change than needles or RF alone.
The big difference vs. light-based devices: Sylfirm X is safe across the full Fitzpatrick range (I–VI). Lasers and IPL carry pigment risk on darker skin tones; RF does not. That's the reason we added Sylfirm X to the practice — to serve patients who can't safely use a laser.
Two modes, one protocol per concern.
At Reviv Med Spa in Millbrae, every Sylfirm X session starts with a face-to-face skin assessment — Fitzpatrick type, pigment history, scar pattern, what we're trying to change. The setting and mode are chosen for what we're treating, not a one-size-fits-all default. Pigment-sensitive cases (melasma, PIH, darker skin tones) get Dr. Misle's direct oversight on settings.
Sylfirm X has two RF modes — we use them differently:
- Pulsed Wave PW mode
- Short, controlled energy bursts. Gentler. Used for melasma, post-inflammatory hyperpigmentation, persistent redness, and rosacea — anywhere pigment safety is the priority.
- Continuous Wave CW mode
- Sustained energy at depth. Stronger remodeling. Used for atrophic acne scars, stretch marks, deeper texture, and lower-face laxity.
- Gold-tip needles insulated
- Insulated along the shaft so the surface (epidermis) stays intact while RF energy lands at the chosen depth in the dermis.
- Adjustable depth 0.3–4.0 mm
- Depth is set per area — shallower for delicate eye-area or thin skin, deeper for scars and laxity.
Topical numbing cream is applied for 30 minutes before we start. The treatment runs 30–60 minutes depending on area size. After treatment we apply a soothing serum and send you home with a written aftercare protocol — gentle cleanser, healing balm, mineral SPF, and the list of actives to avoid for 5–7 days. Most patients return to work the next day with a tinted SPF.
Standardized progress photos at each session let you see the change side-by-side rather than guessing.
Eight indications, one device.
In your consultation we'll identify which indications are highest priority and which mode (PW vs. CW) the protocol calls for.
Melasma
Pulsed Wave (PW) mode targets pigment without aggravating it — a discipline that traditional lasers struggle with.
Redness / rosacea
Reduces visible vascular flushing and the persistent background redness of rosacea.
Acne scars
Atrophic, rolling, and boxcar scars — RF + microneedling remodels the dermis underneath.
Post-acne pigment
Post-inflammatory hyperpigmentation that lingers after acne clears.
Large pores
Visible facial pores along the cheeks, nose, and chin.
Fine lines + texture
Crepey skin, fine surface lines, uneven texture across cheeks and jawline.
Skin laxity
Mild jawline and lower-face laxity — collagen remodeling tightens over months.
Stretch marks
Mature stretch marks across the abdomen, hips, or thighs respond to dermal RF.
Scalp + hair
Off-label scalp protocol uses Sylfirm energy to support follicle health.
The cases lasers struggle with.
Pigment + redness in one device
Most lasers force a choice between pigment and vascular targets. Sylfirm X's Pulsed Wave mode handles both, even on melasma-prone skin.
Acne and traumatic scars
Atrophic acne scars, rolling scars, and traumatic surgical scars all respond to dermal RF energy and microneedling — usually a series of 3–4 over several months.
Mild laxity without surgery
Jawline softening and lower-face laxity respond to RF-driven collagen remodeling. Not a substitute for a facelift; a clear non-surgical option.
Pore size + skin texture
Cheek and nose pores, post-acne texture, and uneven skin tone all improve over a multi-session series.
Skin types Fitzpatrick I–VI
Because Sylfirm relies on RF rather than light energy, it's safe across the full skin-tone range — including patients laser energy can't safely treat.

- 01
Sylfirm X uses two modes — Pulsed Wave (PW) and Continuous Wave (CW). PW is gentler and safer for pigment-sensitive concerns like melasma; CW drives deeper remodeling for laxity and scars. The right protocol depends on what we're targeting.
- 02
It's a series, not a one-and-done. Most patients see meaningful change after 3–4 sessions spaced 4 weeks apart. Some pigment cases run longer — we set realistic expectations at consultation.
- 03
Downtime is real but short. Expect pink or red skin for 24–48 hours and a sandpaper texture for 2–3 days as the micro-channels close. Most patients return to work the next day with a tinted SPF.
- 04
Pricing is per session and quoted in writing at consultation. Series packages are quoted alongside single sessions so you can plan the full course.
From day zero, through six months.
Numbing cream applied for 30 minutes. Treatment runs 30–60 minutes. Skin will feel warm and look pink immediately after — like a strong sunburn.
Pink-to-red skin, mild swelling, and a sandpaper texture as the micro-channels close. Use only the gentle aftercare we send home with you. No actives, no makeup day 1.
Surface heals. First subtle improvements in tone and pore appearance start to show. Continue daily SPF 30+ and gentle skincare.
Collagen remodeling continues for 3–6 months. Full result shows after the complete series of 3–4 sessions. We compare standardized photos at each follow-up.
What it actually costs.
Sylfirm X pricing at Reviv is per session, with series-package pricing for the full course of 3–4 sessions. Final cost depends on the area treated, the protocol your skin requires, and whether you're combining Sylfirm with other treatments. We quote in writing at consultation, before any treatment begins.
Who it's for — and who it isn't.
- Patients with melasma, post-inflammatory hyperpigmentation, or persistent redness who want a pigment-safe device
- Patients with atrophic acne scars or surgical scars looking for dermal remodeling
- Patients with mild lower-face laxity who aren't ready for surgery
- Patients across all Fitzpatrick skin types — including darker skin tones that lasers can't treat safely
- Patients with active acne or active skin infection in the treatment area
- Patients with an active autoimmune skin disease flare (eczema, psoriasis, lupus)
- Patients with an implanted electronic device (pacemaker, defibrillator)
- Pregnant patients

Mapped to the concern.
Sylfirm X has Pulsed Wave and Continuous Wave modes. We choose between them — and adjust depth, energy, and pass count — based on what we see on your skin that day. Same device, very different settings for melasma vs. pores vs. laxity.
What people say about Reviv.
The whole team takes their time. No upselling, no pressure — just a thoughtful plan and beautiful results. The space itself feels like a sanctuary.
I've tried four other med spas in the Bay Area. Reviv is the only one where I feel genuinely listened to. Worth the drive from the city.
Conservative, honest, and skilled. They told me I didn't need half of what I was considering — and the things they did do were perfect.

How is Sylfirm X different from regular microneedling?
Traditional microneedling uses needles alone — small punctures stimulate a wound-healing response that builds collagen on the surface. Sylfirm X adds radiofrequency energy delivered through gold-tip insulated needles, so the heat is placed at a precise depth in the dermis without injuring the surface. The added RF makes it more effective for laxity, scars, and pigment than needles alone.
What does "PW vs. CW" mean?
Sylfirm X has two energy modes. Pulsed Wave (PW) delivers very short, controlled bursts — gentler, safer for pigment, and the protocol of choice for melasma, post-inflammatory hyperpigmentation, and persistent redness. Continuous Wave (CW) delivers sustained energy at depth — better for scar remodeling, deeper laxity, and texture. Most patients use a blend across the series, customized to their goals.
Is Sylfirm X safe for darker skin tones?
Yes. Because Sylfirm relies on radiofrequency rather than light, it's safe across all Fitzpatrick skin types (I–VI). Light-based devices (lasers, IPL) carry pigment risk on darker skin; RF microneedling does not. This is one of the most important reasons we added Sylfirm X to the practice.
Does it hurt?
Most patients describe it as a strong vibration with mild pinpricks. We apply a topical numbing cream for 30 minutes before treatment, which makes most of the session comfortable — a 3–5 out of 10. Sensitive areas like the upper lip can feel sharper.
How many sessions do I need?
Most concerns improve meaningfully after a series of 3–4 sessions spaced about 4 weeks apart. Acne scars and stretch marks sometimes need a longer series. We map the plan at consultation and reassess at each session.
How soon will I see results?
You'll see initial smoothing and tone improvement within 2–4 weeks. Collagen remodeling continues for 3–6 months — the full result shows after the complete series finishes. We track standardized photos at each follow-up so you can see the change.
Is there downtime?
Expect 24–48 hours of pink-to-red skin and a sandpaper texture for 2–3 days. Most patients return to work the next day with a tinted mineral SPF. No actives (retinol, AHAs, vitamin C) for 5–7 days. We send a written aftercare protocol home with you.
How does it compare to Halo or MOXI?
Halo and MOXI are hybrid fractional lasers — they remove a tiny amount of surface tissue along with their dermal effect. Sylfirm X is non-ablative; it leaves the surface intact. Sylfirm is generally safer for darker skin and pigment-prone patients; Halo can deliver a more pronounced surface texture change in patients whose skin tolerates it. We use both at Reviv and will recommend the right one for your skin type and goals.
How much does Sylfirm X cost?
Pricing is per session, with series-package pricing available so you can plan the full course. Final cost depends on the area treated and the protocol your skin requires. We quote in writing at consultation, before any treatment begins.
Can I combine Sylfirm X with other treatments?
Yes — Sylfirm pairs well with Botox (placement spaced apart), filler (placed on a different visit), and Skinvive (placed 2–4 weeks apart). We'll plan the combination at consultation. Some lasers and Sylfirm should be spaced apart to let the skin recover between treatments.
