Photobiomodulation

Emitting equipment parameters

Wavelength, irradiance, and beam coherence determine the biological response to light therapy.

Protocol criteria

Calibrated emission at red (660 nm) and near-infrared (850 nm) wavelengths
Clinically verified uniform power density across the treatment field
Complete absence of harmful ultraviolet radiation

Specific clinical limit

Calibrated for photobiological purposes; this is neither a tanning bed nor a simple heat lamp.

Emitting equipment parameters

Wavelength, irradiance, and beam coherence determine the biological response to light therapy.

Protocol criteria:

Calibrated emission at red (660 nm) and near-infrared (850 nm) wavelengths
Clinically verified uniform power density across the treatment field
Complete absence of harmful ultraviolet radiation

Photobiomodulation depends on selective photon absorption by cellular chromophores rather than superficial thermal heating. Fenix medical panels deliver verified irradiance to ensure therapeutic energy transfer without thermal tissue stress.

02 — Exposure

Optical attenuation and distance

Light energy attenuates exponentially through dermal tissue; maintaining proper distance is part of the dosage.

Protocol criteria:

Regulated distance between emitting surface and patient body
Homogeneous exposure over the target anatomical field
Mandatory ocular protection using wavelength-specific goggles

Tissue scattering and absorption coefficients reduce photon energy progressively with depth. Maintaining a stable, calibrated distance ensures that surface irradiance remains precisely within the targeted therapeutic window.

Light penetration is not uniform across all tissue types and decreases rapidly with depth.

03 — Mechanism

Photonic cellular interaction

Photons in the red and NIR spectrum are absorbed by mitochondrial cytochrome c oxidase.

Protocol criteria:

Photonic absorption along the mitochondrial electron transport chain
Support for cellular energy synthesis (adenosine triphosphate / ATP)
Modulation of oxidative signaling and cellular repair cascades

Photon absorption facilitates transient nitric oxide dissociation from cytochrome c oxidase, promoting electron transport and optimizing mitochondrial membrane potential within physiological margins.

Photonic stimulation supports natural cellular functions; it does not artificially recharge the body.

04 — Dose

Arndt-Schulz law and therapeutic dosing

In photobiomodulation, higher energy does not equal greater benefit: biological response follows a biphasic curve.

Protocol criteria:

Session times calibrated from 10 to 20 minutes per protocol
Frequency adapted to tissue tolerance and clinical goals
Avoidance of excessive dosing that inhibits biological response

Sub-threshold doses may fail to trigger cellular signaling, while excessive irradiance can induce inhibitory oxidative stress. Treatment duration and intervals are calculated with clinical precision to remain in the therapeutic window.

Photobiomodulation supports muscle recovery and skin vitality without promising instant physical transformations.

Information for your decision

What it is

Photobiomodulation uses specific red and near-infrared wavelengths. The protocol is selected according to the goal, treatment area, and prior evaluation.

What the evidence supports

It may provide temporary relief of minor muscle and joint pain associated with overuse, sprains, or arthritis.
It may help support muscle recovery after training.
It may help support collagen production and skin firmness.
It may support mitochondrial energy production at the cellular level.

Evidence boundary

FDA 510(k) clearance is not FDA approval of every use. Results depend on the device, dose, and indication.

Educational information only; not a substitute for medical advice, diagnosis, or treatment. Eligibility, protocol, and outcomes vary by person and indication.

Before you book

Where this therapy stops

No therapy is for everyone, and saying so before you book is part of the service. This comes from our clinical protocols, not from a brochure.

What a session looks like

Wavelength, distance, duration, and frequency are part of the protocol. They are defined according to the available device and evaluated goal.

What has to be evaluated first

None of these is an automatic no: it means the evaluation happens first, and the decision is a medical one.

Active photosensitivity.
Unevaluated skin cancer in the treatment area.

What the protocol requires at every session

It does not depend on who is on shift. It is what the protocol always asks for.

Eye protection, required without exception.
Confirmation of the prescribed treatment area and exposure time.

This list is not a substitute for an evaluation. If you take medication or have a condition that is not listed here, say so at the consultation anyway.
