You found your people!

Whether you just stumbled across red light therapy (RLT) or you’ve been running panels for years, this is the place for you. This forum was created as a home for honest, experience-based conversation on RLT.

Why this forum exists

Most RLT content is either buried in academic research that takes a PhD to decode or comes from brands trying to sell you something. There was no neutral, community-owned space where everyday people could talk about it honestly. This forum is that space. Here, feel free to ask real questions and get real answers from real people who actually use it.

Who belongs here

Everyone. If you're curious about RLT, you belong here. That includes total beginners, people using RLT for a specific health goal, health practitioners, science-minded folks, and longtime users who just want a community that gets it.

What is red light therapy?

- Red light therapy (RLT), also called photobiomodulation (PBN) or low-level laser therapy (LLLT), uses specific wavelengths of red and near-infrared light to stimulate cellular function. The light penetrates the skin and is absorbed by mitochondria, the energy-producing structures in your cells, triggering a range of biological responses. It's non-invasive, drug-free, and backed by a growing body of peer-reviewed research, though it's worth knowing up front that not every claimed benefit has equal evidence.

The wavelengths that matter

- Red light (630-700nm): Penetrates the skin's surface; best for skin health, wound healing, and surface-level tissue.

- Near-infrared (800-1060nm): Penetrates deeper into muscle, joints, and bone; better for pain, inflammation, and recovery.

What people use it for

- Skin health: Collagen production, fine lines, texture, acne, wound healing

- Pain and inflammation: Joint pain, arthritis, tendonitis, post-injury recovery

- Sleep and energy: Circadian rhythm support, fatigue, mitochondrial energy output.

- Athletic recovery: Muscle soreness, performance and faster recovery between sessions.

- Hair growth: Stimulating follicles, androgenetic alopecia, and scalp circulation

- Mental wellness: Mood, seasonal depression, cognitive function, emerging research.

Choosing a device

- Look for devices that publish their irradiance (power output) in mW/cm2

- Wavelength accuracy matters. Ask for spectral reports, not just claimed nm value.

- Panel size should match your use case: targeted devices for face/joints, full panels for full-body

- EMF levels, flicker rate, and build quality are worth researching before buying.

- Price doesn't always equal quality. Research or ask the community before committing.

Basic protocol to start with

- Distance: 6-12 inches from the panel is the most common starting point.

- Duration: 10-20 minutes per area per session. 

- Frequency: 3-5x per week for most use cases.

- Consistency matters more than intensity. Daily short sessions beat sporadic long ones.

- More is not always better. Follow dosing guidelines and watch how your body responds.

Welcome to the Redlighttherapy.com forum, a community for talking about all things red light therapy. Ask your questions, share what's worked for you, and post your results. All we ask is that you follow the community rules and guidelines. Here's how to engage in the community:

To post

1. Search first. Before you post, run a quick search to see if someone's already asked the same thing. If a good thread exists, add to it instead of starting a new one. It keeps answers in one place and saves you the wait for replies that already exist.
2. Go to the right topic area. Open the subforum or category that fits: skin health, devices, protocols, research, and so on. Posting in the right place means the right people see it.
3. Open the topic area, then click "Add a topic." Click the category title to open it, then click the "Add a topic" button to open the post composer.
4. Write a clear, specific title. "Does red light help with knee inflammation?" gets better responses than "Question about my knee."
5. Fill in the body with context. Write your question or experience in the body box. Include your device, how long you've been using it, your protocol, what you've tried, and what you're hoping to learn.
6. Add a photo if it helps. Progress shots, device setups, and placement questions all work better with an image. Before/after photos are welcome. Just make sure they follow the community content guidelines.
7. Set your post options. You can set a post to private for limited visibility and add tags to make it easier to find. (Pinning a post as sticky is mods only.)
8. Subscribe to your topic. Check subscribe so you get notified when someone replies. Don't post a question and then miss the answers because you forgot to check back.

To reply

1. Open the thread and read it fully. Read the original post and the replies before you jump in, so you're not repeating an answer someone already gave.
2. Click "Reply." The button sits at the bottom of the thread and under each individual post. Replying under a specific post keeps your response tied to what you're answering.
3. Quote if you're responding to a specific point. Use the quote option to pull in the part you're replying to. It helps in longer threads where it's not obvious who or what you're answering.
4. Mention someone with @. Type @ followed by their username to tag them so they get notified. Useful when your reply is aimed at one person in a busy thread.
5. Be specific and share your own experience. "It helped my knee" is less useful than "I ran 850nm for 10 minutes a day for six weeks and the stiffness eased." Details are what make a reply worth reading.
6. React instead of posting "thanks." If a reply helped, use the like or reaction button rather than adding a one-word post. It signals a good answer without cluttering the thread.
7. Subscribe if you want to follow the conversation. Check subscribe on threads you're invested in, so you catch new replies even when you're not the one who started it.

• The best time of the year

Jingle bells.

Red light (around 660nm) for fine lines, texture, and collagen. Results are gradual and consistency matters — share devices, distances, routines, and honest before/after timelines.

Recovery, scars, rosacea, and post-procedure redness. Share what has helped — and remember RLT is complementary here, not a substitute for a dermatologist.

Using red and near-infrared light (around 850nm) for muscle soreness (DOMS), joint pain and arthritis, tendons, and post-workout recovery. Share your protocols, timing, and what has actually helped — and remember RLT is a recovery aid, not a replacement for rehab or your doctor.

Red light doesn't suppress melatonin the way blue light does, so many people use it in the evening. Share routines, timing, and whether it has helped your sleep. The evidence here is still early — keep expectations realistic.

A place to discuss red and near-infrared light for mood, stress, and focus. The research here is still early and limited, so please keep it supportive and experience-based — not medical advice. If you're struggling, talk to a professional.

An honest space for RLT and body composition. The evidence is mixed and it is not a fat-loss shortcut — some studies show only modest circumference changes when paired with diet and exercise. Share realistic experiences and what you combine it with.

Owners using red and near-infrared light for dogs, cats, and horses — senior joints, wounds, and recovery. Always work with your vet, and share what has helped (and what hasn't).

Low-level light therapy for pattern hair loss and thinning — devices, wavelengths, and how long results took. FDA-cleared options exist; share your timeline and what worked (and what didn't).

Brand-neutral help picking a device — panels, masks, wands, and full-body setups. The specs that matter: irradiance (mW/cm²), wavelengths (red around 660nm and near-infrared around 850nm), coverage and size for your goal, low flicker and EMF, and FDA clearance. Ask for third-party numbers, not just marketing claims. What are you comparing?

How far, how long, how often — and staying safe. General starting points: a sensible distance per your device, roughly 10 minutes per area, a few times a week, and consistency over intensity (more isn't always better — there's a sweet spot). Red light doesn't use UV, but bright panels can bother your eyes, so use the goggles that come with your device and don't stare into it.

New here? Say hello and tell us what brought you to red light therapy. This is also the spot for anything that doesn't fit the other boards — general questions, wins, and RLT chit-chat.
