How often should you use red light therapy?

Skin: four to five sessions a week early on, easing to two or three for maintenance once you're happy with where things are. Skin responses are cumulative and slow, so consistency over months is what matters.

Recovery and soreness: around training. Many people use light after hard sessions, or on the same day, three to five times a week depending on their training load.

Aches and stiffness: daily or near-daily short sessions on the affected area during a flare, then dropping back once things settle.

Sleep: consistent timing matters more than count. An evening or early-evening session most days of the week is the common pattern.

Photobiomodulation follows a biphasic dose response: too little does nothing, an optimal band produces the effect, and substantially more can reduce it. This is unusual for a wellness habit and it's the single most misunderstood point in the field.

Practically, this means the manufacturer's session times are a ceiling, not a suggestion. If your device is high-output, its shorter recommended sessions are a feature.

Rest days aren't a problem. Missing a day costs you very little; running triple-length sessions to compensate can cost you more.

Soreness and recovery: often within the first one to two weeks, sometimes the same evening.

Aches and stiffness: usually two to four weeks of consistent use before a clear pattern emerges.

Skin: four to twelve weeks. Photograph in the same light at the start — memory is a poor baseline.

Sleep: often within a couple of weeks, though this is the most variable of the four.

Attach the session to something you already do — after training, before your evening shower, while listening to something. Compliance is the real variable behind most success and most disappointment.

Choose the device that fits the schedule, not the one with the best specs. A full-body bed makes frequency easy because one 15-minute session covers everything; a handheld demands more of your attention for less coverage.

Review at eight weeks rather than eight days. If nothing has changed by then, revisit your dose, distance, and how much skin is actually exposed before concluding it doesn't work for you.
