Ask ten suppliers what a facial machine is and you'll get ten different boxes. It's a taxonomy problem, and it costs real money when the wrong box lands in your treatment room. Four of the routes sold under that phrase are energy or force platforms we build. Different mechanisms, different depths, different consumable bills.
So here's the map: what each route does to tissue, how deep it gets, which platform sits on it. Other things get sold as a facial machine and aren't covered here — mechanical abrasion rigs with a crystal or diamond tip, LED phototherapy panels, ultrasound and microcurrent units. Simple reason. We don't build them, so we won't pretend to have an opinion on their specifications.
Route 1: jet-based cleansing and infusion
This is the only category that uses no energy source at all. Just momentum.
Compressed gas, medical oxygen or clean air, accelerates a thin stream of saline and nutrient liquid through a narrow nozzle. Our device manuals put the particles at 50 to 80 microns, and the spec table caps spray velocity at 230 m/s. Small enough to enter a follicular opening. Fast enough to lift sebum and debris back out. Working pressure sits in a 0.3-0.6 MPa band; distance from the skin, not a power dial, sets intensity.
How deep it actually reaches
Stratum corneum and the follicular canal. A jet clears and hydrates the surface and delivers water-soluble actives without a needle. It won't remodel dermal collagen or fill an atrophic scar, and anyone pitching it as resurfacing is overselling. Our OJ-01 water and oxygen jet is the platform here, usually run as prep ahead of an energy device.
Route 2: pulsed light, meaning IPL and E-light
Now we're into photons. A flashlamp fires a broad spectrum, filters cut the short end, and what survives gets absorbed by whichever chromophore matches the window. Anderson and Parrish set out the governing rule in Science in 1983: pick a band your target absorbs better than the tissue around it, then deliver the dose faster than that target sheds heat.
The filter cut-off decides the job
Our engineering archive lists three standard cut-offs, each running to 1200 nm: 530, 585 and 610 nm, with 430 and 560 on some builds. A 530 cut-off lets in the green band superficial melanin and oxyhaemoglobin both grab: tone and redness work. Push to 610 and you've dropped the part epidermal pigment absorbs hardest, so more of the dose survives down to the follicle bulb. Our light-tissue archive explains why the long end stays useful: between 600 and 1200 nm scattering falls away and competing pigment absorption is limited. That's the optical window into deeper skin, and our wavelength map lays the bands out side by side.
Why E-light bolts RF onto the same shot
Light picks its target by colour, which is precisely the problem on darker skin. Radiofrequency reads no colour. It heats dermal water. Pair them and the RF pre-warms the target, so the optical dose needed to finish drops. Fluence on these platforms runs to around 50 J/cm2, with the RF stage at 2.64 MHz. Two options here, and the split isn't about which one has an RF handpiece — both carry the same F+E, F+E+ and RW-V set. PE-01 is the pulse-quality build: homogeneous output, contact tip held between -2 and 0 degrees C, RF stage rated at 50 W or less. The MF-05 console takes its RF stage to 120 W, so body zones get more headroom. Typical menu: photorejuvenation, vascular work, inflammatory acne, hair reduction.
Route 3: ablative and fractional resurfacing
Different physics again. The target is tissue water, not pigment, and the aim is controlled injury rather than selective heating.
10600 nm CO2, ablative
Water absorbs mid-infrared far harder than near-infrared. Our archive's absorption curve puts the largest peak at 2940 nm and strong absorption across the CO2 band, so a 10600 nm beam is consumed almost the instant it enters tissue. Past roughly 300 degrees C, our thermal-effects chapter states, tissue vaporises and fragments instead of merely coagulating, leaving a defect ringed by coagulated tissue. That threshold is the line between an ablative device and a heating one.
Fractional means you don't ablate the whole surface. Manstein and colleagues formalised the grid in Lasers in Surgery and Medicine in 2004: microscopic treatment zones separated by untreated skin that supplies the repair. On CF-01: spot 50-2000 um, pulse width 0.067-0.67 ms, 2-200 mJ per spot, densities from 6x6 to 24x24 per square centimetre.
1550 nm erbium glass, non-ablative
Same fractional logic, gentler execution. Water still absorbs at 1550 nm, just far less violently, so each micro-column coagulates dermis while the surface stays closed. EF-01 reaches roughly 2 mm at its deepest and offers 36, 144, 324 and 576 spots per square centimetre — roughly 1.56, 6.25, 14.06 and 25 percent coverage. Melanin barely competes here, so the treatable skin-type range widens against a 532 or 694 nm device. Clients go back to work the same week. You trade single-session power for tolerability, and on scar work that often pays.
Route 4: radiofrequency tightening
No light source anywhere in this one. An alternating field agitates dermal water, friction produces heat, warmed collagen contracts. The durable part arrives later, through ordinary healing.
RF-01 runs at 2.64 MHz with bi-polar and mono-polar tips on one handpiece. Bi-polar keeps heat shallow — the archive rule of thumb puts its penetration near half the electrode spacing. Mono-polar pushes current toward a return patch and goes deeper, which is what makes a body menu possible on one console. Dwell time separates them in practice: our RF parameter charts run 6 to 8 seconds per facial zone against 12 to 16 on body zones.
Our training archive uses a measured surface reading of 41 degrees C for three minutes, or 42 degrees for one to two minutes, as its criterion that a thermal effect happened — a confirmation test, not a target. The RF-01 treatment protocol works to 40-41 degrees for one to two minutes on facial skin, three to five minutes where skin is thick, and holds the epidermal end point under 45 degrees. The training archive also notes most human cells tolerate 40 to 45 degrees, yet twenty minutes there can be lethal to fibroblasts. Published work frames it the same way: Yarmolenko and colleagues, reviewing thermal damage thresholds in the International Journal of Hyperthermia in 2011, treat injury as cumulative time above roughly 43 degrees, not one fixed line. Contact cooling exists for this reason. Skin type caps what you can safely deliver — see Fitzpatrick and parameter ceilings — and the skin tightening page carries indication detail.
The four routes side by side
| Route | Physical mechanism | Primary target | Depth reached | Platform in range | Downtime |
|---|
| Jet | Momentum, no energy source | Sebum and surface debris | Stratum corneum and follicular canal | OJ-01 | None |
| IPL / E-light | Selective photothermolysis; RF adds water heating | Melanin, oxyhaemoglobin, follicle bulb | Epidermis into dermis, 600-1200 nm window | PE-01, MF-05 | Minimal |
| Fractional resurfacing | Water absorption: ablation at 10600 nm, coagulation at 1550 nm | Tissue water | Dermal; EF-01 near 2 mm at its deepest | CF-01, EF-01 | Real on CF-01, light on EF-01 |
| RF | Alternating field agitates dermal water | Dermal water, no chromophore | Bi-polar near half the electrode spacing, mono-polar deeper | RF-01 | None |
Configuring a room: which routes do you actually need?
Few clinics need all four on day one. A rough ordering:
- Light platform first. Widest menu per unit of capital: hair, vessels, pigment, acne, tone.
- Jet second. Cheap consumables, short sessions, and every other device then works on clean skin.
- Fractional third, and pick your temperament. CO2 if the case mix is scarring and deep photoageing and clients accept downtime; 1550 nm if it's texture, mild laxity and lunchtime expectations.
- RF where light can't go. Laxity in darker skin types, plus body zones.
The classic mistake is buying twice on the same route. Two light consoles is a rounding error in capability; a light console plus a fractional laser is a different clinic. Floor plan and staffing belong to our equipment buildout guide; this page stops at the physics. Our product range shows where each sits.
What to check before you sign
Spec sheets are easy to write and hard to verify. Anchor the conversation to documents.
- Standards, matched to the route. IEC 60601-1 is the general baseline under all four. Laser sources — CF-01 at 10600 nm, EF-01 at 1550 nm — add IEC 60601-2-22. IPL and E-light are not lasers, so they answer to IEC 60601-2-57, which covers non-laser optical sources from 200 to 3000 nm. Jet and RF platforms stop at 60601-1. Ask which edition, and ask to see the file. Room-level laser controls sit in our Class 4 safety notes.
- Ranges, not headline numbers. A 30 W tube tells you less than the pulse-width range, and pulse width decides whether you ablate or slowly cook.
- Consumables and wear parts. Flashlamps get consumed. Sealed CO2 tubes have a service life. The jet burns only saline and gas. Get replacement pricing in writing.
- Cooling, duty cycle, install. Tip temperature and recovery between shots govern throughput on a full day. Voltage, plug type, ventilation and operator certification vary by market — our service page covers it.
Who wrote this, and from what. Our applications engineering team compiled it from the device manuals, parameter charts and training material behind each platform, re-checking every figure in July 2026.
One caution worth repeating. All four push energy or force into living tissue, and all four carry real risk in untrained hands: burns, post-inflammatory hyperpigmentation, scarring. Any atypical lesion belongs with a dermatologist before a device touches it. Technical background for equipment selection, not clinical guidance.
Frequently asked questions
Can one facial machine cover everything?
No, and be sceptical of anyone who says otherwise. An E-light console is the broadest single purchase, since light plus RF spans a lot of ground. It still can't ablate tissue or jet-clean a follicle. Multifunction means several modules sharing one cabinet, not one mechanism doing several jobs.
CO2 or 1550 nm, which fractional laser should I buy first?
Depends on how much downtime your market tolerates. CO2 at 10600 nm ablates, so visible change comes faster and so does the recovery. The 1550 nm route coagulates without opening the surface, clients keep working, and you plan a series instead. Practices serving people who can't take a week off usually start with 1550. Happy to walk your case mix through — get in touch .
Is radiofrequency safe on darker skin types?
The mechanism doesn't target melanin, which is why RF gets used where light-based tightening turns awkward. That isn't blanket clearance. Epidermal temperature control and operator technique still decide the outcome, and PIH risk never drops to zero.
What does the jet do that a light or laser device can't?
Mechanical clearance of the follicular opening, plus needle-free delivery of water-soluble actives. Nothing on the optical side does either. Consumables are saline and gas — no flashlamp counting down its rated shots, no sealed CO2 tube with a service life — so marginal cost per treatment is the lowest of the four.
