How often and for how long should red light therapy be used?

There is no universal treatment time that applies to every red light device and every application. The correct duration depends on the light parameters, distance, treatment area, and purpose.

Why 10 minutes is not always 10 minutes

Ten minutes with low irradiance delivers a different energy dose than ten minutes with much higher irradiance. Treatment time should therefore be considered together with light intensity.

Follow product-specific instructions

Use the recommended distance, duration, and frequency for the specific device. Do not use a protocol from another device as if the light parameters are identical.

Why more is not automatically better

PBM is researched with specific dosages. The consensus literature emphasizes the importance of safe and effective parameters.

A good routine

  1. Check wavelength and parameters.
  2. Use the recommended distance.
  3. Adhere to the recommended treatment time.
  4. Use the recommended frequency.
  5. Be consistent.

Conclusion

The best routine is not the longest routine, but a protocol that suits the device and can be performed responsibly.
