Frequently Asked Questions

What is red light therapy?

Red light therapy uses specific wavelengths of visible red and near-infrared light as part of a process often described as photobiomodulation.

What is near-infrared light?

Near-infrared light is invisible to the human eye and has optical properties that differ from visible red light when interacting with tissue.

Is red light therapy the same as heat therapy?

No. PBM is primarily based on light–tissue interaction rather than simply raising tissue temperature, although some devices may also feel warm during use.

How often should red light therapy be used?

Use frequency depends on the device, treatment area and product instructions. Follow the guidance provided with your DEPOWIN device.

Does irradiance matter?

Yes. Irradiance describes the optical power reaching an area and works together with distance and treatment time to influence total light exposure.

What does PBM mean?

PBM stands for photobiomodulation, a term used to describe how specific wavelengths of light may influence biological activity under certain treatment parameters.
