Red light therapy (RLT) has moved from the fringes of alternative wellness into the mainstream — and for good reason. Backed by thousands of peer-reviewed studies, this non-invasive technology is now used by elite athletes, dermatologists, physiotherapists, and everyday Australians looking to optimise their health naturally.
What Is Red Light Therapy?
Red light therapy, also known as photobiomodulation (PBM) or low-level laser therapy (LLLT), uses specific wavelengths of red and near-infrared (NIR) light to penetrate the skin and stimulate biological processes at the cellular level.
Unlike UV light (which damages DNA) or infrared heat lamps (which simply warm tissue), red and near-infrared wavelengths interact directly with the mitochondria — the powerhouse of your cells — to increase the production of adenosine triphosphate (ATP). More ATP means more cellular energy, faster repair, and better function across virtually every tissue in the body.
The Key Wavelengths
Not all light is equal. Research consistently points to two therapeutic windows:
- Red light (630–700nm): Absorbed primarily by skin tissue. Best for skin rejuvenation, collagen production, wound healing, and surface-level inflammation.
- Near-infrared light (800–1100nm): Penetrates deeper into muscle, joint, and bone tissue. Most effective for muscle recovery, joint pain, deep inflammation, and neurological support.
Leredd devices are engineered to deliver precise doses of both wavelengths, optimised for therapeutic outcome.
How Does a Session Work?
Using a Leredd device is simple. You position yourself in front of the panel at the recommended distance (typically 15–30cm for panels), expose the target area of skin, and let the light do the work. Sessions typically run 5–20 minutes depending on the device and your goal.
There's no heat, no discomfort, and no downtime. Many users incorporate sessions into their morning or evening routine, pre- or post-workout, or as a standalone wellness practice.
What Does the Research Say?
Peer-reviewed evidence supports red light therapy for a wide range of applications:
- Reduction in muscle soreness and faster recovery after exercise
- Increased collagen synthesis and improved skin texture
- Reduction in joint pain associated with osteoarthritis
- Improved wound healing and scar reduction
- Support for hair regrowth in androgenetic alopecia
- Improved sleep quality and circadian rhythm regulation
Is It Safe?
Red light therapy has an excellent safety profile. It is non-thermal, non-ionising, and non-invasive. Unlike UV radiation, it does not damage DNA. The main precaution is eye protection — direct eye exposure to high-intensity panels should be avoided, and Leredd recommends using appropriate eyewear during sessions.
As with any wellness intervention, those with active medical conditions should consult a healthcare professional before commencing.
