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.

First things to do

Read the forum rules, check out New to RLT?, browse the FAQ page, and drop a note in introductions.

• Be respectful
  • - Treat every member with basic dignity regardless of background or experience level. While there may be disagreements, disrespect is not tolerated.
    • - No name-calling, insults, racial slurs, or condescending language.
    • - No mocking newcomers or those with less experience.
    • - Assume good faith before responding to something that reads as offensive.
• No medical advice
  • - You can share your own experience all day long. What you cannot do is tell someone else what to do about their health condition, diagnose, or instruct them to stop or start a medical treatment.
    • - Share what worked for you. Don’t prescribe it to others.
    • - Always encourage members to consult a qualified professional for medical decisions.
    • - Posts that read as medical advice will be edited or removed.
• No spam or fake claims
  • - No unsolicited commercial promotion or affiliate links without disclosure.
  • - No exaggerated or unsubstantiated health claims. Back it up, or don’t post it.
  • - No posting the same content across multiple threads.
  • - No creating accounts to impersonate members or brands.
• Privacy & Safety
  • - Do not share a person’s identifying information without consent.
  • - Use the report button. Don’t call out violations publicly in-thread.
  • - One account per person; evading a ban via an alt account results in a permanent ban.
• Enforcement
  • - Most first-time violations follow a warning
    • - Formal warning
    • - Temporary suspension
    • - Permanent ban path
  • - Some offenses (harassment, doxxing, ban evasion) skip straight to permanent ban. Appeals go through the mod team via DM; No public threads.

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.
