How often should you use red light therapy?

Frequency is part of the treatment protocol. Schedules differ across devices and research applications.

Follow the instructions for your device

Consumer devices differ in output and recommended distance. Their schedules can differ too. Start with the manufacturer instructions unless a clinician has given you a different protocol.

Study schedules vary

Photobiomodulation research covers many applications. A protocol used for one condition does not automatically become the right schedule for exercise, skin, or another goal.

Keep a useful record

If you use a home device, note session length, distance, frequency, and the area treated. That creates a clearer record of your routine.
