Frequently asked questions

Yes. We have a warehouse in Portugal and delivery is free nationwide, with no extra taxes or fees.

While it's very unlikely you'll want to return your TheraFactor® panel, we accept returns within the first 60 days with no restocking fee. Returns are sent to our warehouse in Portugal. See the shipping and returns page for more details.

Yes, but we recommend waiting more than 6 hours between treatments.

Any time. Mornings are most common, but you can also use it before or after training.

It depends on your goal and device. Recommended distance, time and frequency are in our usage protocol.

Usually, yes. If your face is close to the panel during a session, eye protection is strongly recommended unless you're looking away or keeping your eyes closed.

Use the device in a well-lit room so your eyes can adjust to the light.

Near-infrared can pass through clothing to some extent, but red light can't. We recommend exposing clean, bare skin whenever your setting allows.

No. Our panels aren't certified for use inside a sauna.

Light therapy is also less effective when the body is covered in sweat: photobiomodulation studies call for a non-thermal environment.

Yes. As with any new treatment, check with your doctor and, if approved, adult supervision is strongly recommended.

For a detailed look at contraindications and other considerations, see our articles.

With red light therapy, more isn't always better: the response follows an inverted U-shaped curve. The big advantage of TheraFactor® devices is getting the same benefits in less time.

We recommend at least 6 hours between treatments of the same area, no more than 15 minutes per session with panels and 20 minutes with flexible devices, 4 to 10 times a week, with at least one day off per week.

As there are no clinical studies of red light therapy in pregnant or breastfeeding women, don't use the device if you're pregnant or breastfeeding without consulting your doctor.

Instead of a continuous NIR wave, pulsing switches the LED on and off very quickly, invisibly to the eye. The frequency is measured in Hertz (Hz), or cycles per second.

Some studies suggest pulsed light heats tissue less, allowing higher intensity to reach deeper without thermal damage. There's no consensus yet on whether continuous or pulsed light is better, or on ideal parameters.

The real benefit of pulsed NIR may be a lower dose, more in line with low-level light therapy (LLLT) science. As new studies emerge, our panels let you choose continuous or pulsed NIR from 0 to 999 Hz.

The angle at which light leaves the LED determines how quickly power density drops with distance. Wide angles (90 degrees) lose intensity fast, which isn't ideal for treating larger areas from further away.

Very narrow angles (30 degrees) need LEDs packed closer together, give higher "peak" readings on smaller devices and can be uncomfortable even to glance at. We consider them generally less safe and less practical.

TheraFactor® panels use an ideal 60-degree beam angle to keep therapeutic power density at greater distances with maximum comfort, usability and safety.

Red light is absorbed closer to the surface, mainly by skin and hair, and is very effective for a healthy, youthful look. Near-infrared (NIR) penetrates several centimetres into subcutaneous tissue, reaching organs, joints, muscles, tendons, ligaments and even the brain.

Usually together, as they work in synergy, but you can also use them separately. At night it's best to use NIR alone, which is invisible and not stimulating.

Near-infrared is beyond the visible spectrum, so you'll only see a faint glow in the centre of the LED. Rest assured it's delivering the intended energy.

Near-infrared gives off a gentle, pleasant warmth.

Thanks to high-quality LEDs, lifespan is excellent: up to 100,000 hours. At the recommended 30 minutes a day, that's over 500 years. No need to worry!
