Ask which source is inside it.
CO2 machines are sold on maximum wattage and a list of modes. Neither tells you what energy actually reaches the skin. This site explains the technology in plain language and gives you the questions that separate a laser platform from a cabinet with a screen on it.
Three things this site will not do
- Promise a result. No downtime figures, no session counts, no before-and-after galleries. Outcomes depend on indication, skin type, protocol and the practitioner.
- Say “FDA approved”. A Class II CO2 laser is cleared under a 510(k) number. Anyone selling you the word “approved” has not read their own paperwork.
- Claim every machine does everything. Intended use, attachments and permitted procedures differ by model and by practitioner qualification.
Every question, one clear page.
Start with the technology, then the components that decide delivered energy, then the buying decision.
What Is a CO2 Fractional Laser?
Ablative, fractional, 10,600 nm — what each of those words actually means for the machine you are buying.

Read guide →Where the energy actually goes
Four components sit between the wall socket and the skin. A weakness in any one of them changes the treatment.
- The sourceAn RF metal tube generates the 10,600 nm beam. Beam quality, power stability and lifetime are decided here - the metal RF tube platform uses a US Synrad tube at M2 <= 1.2 and +/-3% stability.
- The articulated armSeven joints of gold-coated mirrors carry the beam to the handpiece. That platform uses a Korean Hanmac arm at >=99.7% per mirror and >=95% overall transmittance.
- The scannerGerman Phytron stepping motors place each dot on that platform. Position accuracy and dwell time decide whether the pattern is even.
- The tissueWater absorbs the energy, producing controlled ablation and a surrounding thermal zone. What arrives here is the only number that matters.
