Q4TRO: a true laser with four wavelengths.
Q4TRO is a multi-wavelength laser that emits 4 wavelengths combined in every pulse. That lets it treat fine and coarse hair in each session and work safely on every skin tone (I–VI), including tanned and dark skin. It is not pulsed light (IPL/AFT): it is a true laser.
Q4TRO is made by Disair Laser (Miami Beach, Florida, EE. UU.), a company registered with the U.S. FDA. In Panama, this technology is exclusive to Bodyfree: no other clinic can offer it.
Comparing clinics? The guide to the best laser hair removal in Panama City contrasts Q4TRO with diode, alexandrite and IPL, criterion by criterion.
| Criterion | Q4TRO | Diode / alexandrite | IPL / AFT |
|---|---|---|---|
| True laser? | Yes, 4 wavelengths | Yes, 1 wavelength | No: broad-spectrum pulsed light |
| Skin tones | All, I–VI (incl. dark and tanned) | Wide, device-dependent | Limited on dark or tanned skin |
| Typical course | 6 sessions | 10–12 sessions approx. | Variable, often more |
| Result | Visible from session one | Progressive | Variable |
| At Bodyfree | Yes | No | No |
Results vary from person to person.
What people ask about Q4TRO.
What is the Q4TRO laser?
Q4TRO is a multi-wavelength hair removal laser: it emits 4 wavelengths combined in every pulse, with built-in skin cooling. That lets it treat fine and coarse hair, shallow and deep follicles, and work safely on every skin phototype from I to VI. It is the technology Bodyfree uses in Marbella, Panama City.
Is Q4TRO the same as a diode laser?
No. A classic diode emits a single wavelength (about 808 nm). Q4TRO combines 4 wavelengths in each pulse, including the ones used by diode and alexandrite lasers, so it adapts to more skin-and-hair combinations than a single-wavelength device.
Is Q4TRO IPL?
No. IPL and AFT emit a broad spectrum of non-coherent light: they are not lasers, even when marketed as such. Q4TRO is a true laser with defined wavelengths and energy concentrated in the follicle. It is the first thing worth checking when you compare clinics.
Does Q4TRO work on tanned or dark skin?
Yes. By combining long wavelengths that reach the follicle without concentrating in surface melanin, Q4TRO safely treats phototypes IV–VI, including brown, dark and tanned skin. The exact settings for your tone are chosen at a free in-person assessment, so tell the team about recent sun exposure.
How many sessions does a Q4TRO course take?
A complete course with Q4TRO is usually 6 sessions, versus the 10–12 typical of single-wavelength devices. Results are visible from the first session: hair grows back slower and finer. Results vary from person to person.
