Red Light Dosing and How to Use Red Light Therapy

How to Use Your Makiuri Device for Real Results

By The Makiuri Team  |  December 12, 2025

You've done the research. You understand the mechanism. You've invested in a quality device. Now comes the question that determines whether any of it actually works: how do you use it?

Dosing is one of the most underappreciated variables in red light therapy. The right wavelengths at the wrong distance, duration, or time of day will produce underwhelming results — and leave you wondering whether RLT actually lives up to its reputation. It does. But like any precision tool, it rewards thoughtful use.

This guide covers everything you need to know about using your Makiuri device effectively — frequency, duration, distance, and targeted protocols for each of the most common goals. Think of it as the practical companion to the science.

"Light is not a luxury. For your cells, it is a nutrient — and like any nutrient, dose and timing are everything."

Before diving into goal-specific protocols, it helps to understand what 'dose' actually means in the context of photobiomodulation. Unlike a medication where dose is measured in milligrams, RLT dose is a function of three interacting variables: irradiance (the power of the light reaching your skin, measured in mW/cm²), time (how long you expose the tissue), and distance (which directly affects irradiance — the further away, the lower the power delivered).

The relationship between these variables follows a principle called the Arndt-Schulz law, or biphasic dose response: too little light produces minimal effect, the optimal range produces the maximum therapeutic benefit, and too much light can actually inhibit the response. This is why session length and distance matter — and why 'more is more' is not the right framework for RLT.

Makiuri devices are engineered to deliver therapeutic irradiance at the distances recommended in this guide. Our panels have been independently tested by a third-party laboratory and confirmed to perform in the upper tier of devices on the market — meaning the protocols below will produce the irradiance levels the research supports. Full lab results will be available on our website shortly.

For most people beginning a red light therapy practice, the following framework provides a solid, evidence-aligned foundation:

Frequency: 3–7 sessions per week. Daily use is ideal for most goals; consistency matters far more than any single session.

Duration: 10–20 minutes per session on the targeted area. After approximately 15–20 minutes of direct exposure, the dose-response curve begins to plateau — longer sessions don't necessarily produce proportionally greater benefit.

Injuries or sensitive areas: Begin with 2–3 minutes per session and increase gradually as your body adapts and as you observe how the tissue responds.

Device distance: 6–18 inches from the target area, depending on the protocol (detailed per goal below).

Start on the lower end of the frequency and duration ranges if you're new to RLT, and build from there. Your body's response to photobiomodulation is cumulative — results compound over weeks and months of consistent practice, not overnight.

Skin Health and Anti-Aging

Skin is the most well-studied application of red light therapy, and morning is the ideal time for skin-focused sessions. Using RLT within the first one to two hours of waking supports both skin vitality and circadian alignment — the early-day light exposure reinforces your natural rhythm in a way that evening sessions cannot replicate.

Distance: ~25 inches from the target area

Duration: 5–10 minutes

Timing: Morning, within two hours of waking

Use this session time intentionally. Many Makiuri users pair their morning RLT session with deep breathing, light journaling, or a brief meditation — transforming a passive treatment into a grounding start to the day. If targeting the scalp or areas with significant facial hair, be aware that hair can reduce light penetration to the underlying tissue; adjust positioning or part the hair at the target site if possible.

Eye protection: follow your device's specific guidelines. If your Makiuri model recommends protective eyewear, use it — particularly for facial treatments at closer distances.

Red light therapy around workouts is one of the most practically impactful applications in the athlete's toolkit. Research supports both pre-workout use for performance and post-workout use for recovery — with meaningfully different mechanisms driving each.

Pre-workout:

Distance: ~6 inches from targeted muscles

Duration: 3–7 minutes

Timing: Within the hour before training

Pre-workout RLT primes the mitochondria of the targeted muscles — increasing ATP availability, improving oxygen utilization, and setting the stage for better performance output and reduced fatigue during the session.

Post-workout:

Distance: ~6 inches from affected areas

Duration: 3–7 minutes

Timing: 3–6 hours after training

Post-workout use targets the inflammatory response and tissue repair process. Studies document measurable reductions in inflammatory cytokines and muscle soreness within 24–48 hours of post-workout photobiomodulation. The 3–6 hour window allows the initial acute inflammatory response to begin before you modulate it — rather than interrupting it too early.

Near-infrared wavelengths (850nm) penetrate several centimeters into tissue — including through the skull and into superficial cortical structures. Emerging research on transcranial photobiomodulation supports meaningful improvements in cognitive function, mood, and neurological recovery. Our founder Jamie credits morning RLT as a foundational pillar of her cognitive and mood management protocol.

Distance: 6–12 inches from the forehead or target area

Duration: 3–10 minutes

Timing: Morning sessions are preferred for mood and performance support

Hair can reduce light penetration to the scalp and cortical tissue beneath — choose treatment areas with good light access, or gently part the hair at the target site. As with all neurological applications, if you have a diagnosed condition or are under treatment for a neurological or psychiatric disorder, discuss RLT with your healthcare provider before starting.

One of the less-discussed — but profoundly impactful — benefits of red light therapy is its support for circadian rhythm and sleep quality. Unlike blue-dominant light, which suppresses melatonin and disrupts sleep architecture, red and near-infrared wavelengths work with the body's natural light-dark cycle rather than against it.

Morning use:

Distance: 12–18 inches

Duration: 3–10 minutes

Morning RLT reinforces daytime alertness and supports nighttime melatonin production — the same mechanism that makes consistent morning light exposure a cornerstone of sleep hygiene. Many users report meaningful improvement in sleep quality within the first one to two weeks of daily morning sessions.

Evening use:

If using your Makiuri device in the evening, complete sessions at least two hours before bed. Red and near-infrared light is far less disruptive to melatonin than blue light — but higher-irradiance sessions close to sleep can still have a mildly stimulating effect on some people. Adjust timing to suit your own response.

For acute injuries, the principle is straightforward: get light on the affected tissue as soon as possible. The early inflammatory phase of injury response benefits significantly from photobiomodulation — RLT helps modulate inflammation before it becomes chronic, while accelerating the cellular repair processes that drive healing.

Distance: ~6 inches from the affected area

Duration: 3–5 minutes per session

Frequency: Twice daily during the acute phase

For chronic injury, tendinopathy, or post-surgical recovery, longer courses of daily use (4–12 weeks) are typically required to produce meaningful structural improvement. Our founder Jamie's protocol for healing two herniated discs involved 10–20 minute sessions twice daily over several months — consistency and patience were the decisive variables.

Research on RLT and body composition is emerging — not yet as robust as the evidence for skin or pain, but promising. The proposed mechanisms involve improved mitochondrial function in adipose tissue, enhanced circulation, and effects on lipid metabolism. For those incorporating this into their protocol:

Distance: ~6 inches from the target area

Duration: 2–5 minutes

Timing: During a fasting window or first thing in the morning, when fat oxidation pathways are most active

As with all RLT applications, consistency over weeks is required to assess real-world results. This is best treated as one component of a broader approach to body composition — not a standalone intervention.

• Too much distance: irradiance drops rapidly as you move further from the panel. At 24 inches, you may be receiving a fraction of the therapeutic dose compared to 6 inches. Match your distance to the protocol for your goal.

• Sessions that are too short or too sporadic: the research that produces impressive results involves near-daily sessions sustained over weeks. One session per week will not replicate those outcomes. Build it into your routine like a supplement — not an occasional treat.

• Treating RLT as passive: the best results come when RLT is one element of a thoughtful protocol — not the only one. Pair it with anti-inflammatory nutrition, adequate sleep, appropriate movement, and stress management for compounding benefit.

• Skipping eye protection: follow your device's guidelines on this without exception. The eyes contain more photoreceptors per unit area than any other tissue, and direct exposure to high-irradiance panels is not appropriate.

• Expecting overnight results: red light therapy works by accelerating biological processes that take time by nature. Collagen synthesis, nerve repair, and structural healing are measured in weeks and months. The timeline requires patience — but the results are real.

Red light therapy has an excellent safety profile when used as directed. A few important reminders:

• Eye safety: always follow the device-specific guidelines for your Makiuri model. Use protective eyewear where recommended.

• Photosensitizing medications: if you take medications that increase light sensitivity, seek medical advice before starting RLT.

• Pregnancy, epilepsy, active cancer: consult your healthcare provider before beginning any RLT protocol if these apply to you.

• Skin irritation: if you notice unusual redness or irritation, increase distance or reduce session duration and consult a clinician if symptoms persist.

• Individual variation: responses to RLT vary. Some people notice effects quickly; for others, the benefits accumulate more gradually. Consistency is the variable most within your control.

The protocols in this guide are drawn from current photobiomodulation literature and practitioner experience — including the work of researchers like Ari Whitten, whose book Red Light Therapy remains one of the most accessible deep-dives into the science for the motivated non-specialist.

But all the protocol knowledge in the world only produces results if you show up consistently. The research behind photobiomodulation is compelling precisely because it was done on people who used devices regularly, for sustained periods, with intention. That's the standard we'd encourage you to hold yourself to.

Makiuri devices are built to deliver what the research requires — the right wavelengths, at verified irradiance, session after session. The rest is up to you.

Your cells are ready. Give them the light — and the consistency — they need.
