FAQs
What is Red Light Therapy?
Red light therapy (RLT), also called photobiomodulation (PBM), is a non invasive, science backed treatment that uses specific wavelengths of red (approx. 630 - 670 nm) and near-infrared (approx. 810 - 850 nm) to stimulate the body's natural healing processes. It boosts cellular energy (ATP), to repair, regenerate, reduce inflammation and support recovery.
Why haven't I heard about Red Light Therapy before now?
You are not alone. The truth is, RLT has quietly gathered mountains of evidence while flying under the radar of mainstream media. It doesn't have billion dollar pharmaceutical backing and it doesn't make flashy headlines. But in the world of functional medicine, sports therapy, and natural healing, it has become a staple.
Now with the available of safe and effective at-home devices, you don't need to wait for a clinic appointment to access the same science-backed benefits. You can start applying what the research has shown, in your own home, on your own terms.
Is Red Light Therapy safe?
Yes. Red Light Therapy is not only safe when used properly - it is one of the most extensively tested non-invasive modalities in modern wellness and regenerative care. It is constantly classified as low risk.
RLT is non-ionising and painless. It works best when you use a high quality, well engineered device, you follow guidelines, you protect sensitive areas like the eyes and you stay consistent.
Avoid treating any suspicious skin lesion and speak to your GP if you’re pregnant, photosensitive or on light-sensitising medication.
Are all Red Light devices the same?
Not all devices are created equal. For effective therapy a device should:
- Emit wavelengths in the therapeutic range (typically 630-670nm for red, 810-850nm for NIR)
 - Deliver sufficient irradiance (power density, measured in mW/cm²
 
You can search for 'Red Light Therapy' devices online where you can find hundreds of options from £40 wands to £5000 full body panels. Unfortunately, many of these devices look similar but differ greatly in quality, power output, EMF's and wavelength accuracy.
Will it tan or burn my skin?
No. Red/NIR LEDs contain zero UV, so they won’t tan or burn.
Which wavelengths and power should I look for?
Look for mixed diodes around 630 - 660 nm (red) and 810 - 850 nm (NIR) with a measured irradiance close to ~100 mW/cm² at the panel surface for efficient sessions.
How long and how often should I use it?
This answer to this can be quite complex as RLT operates on a biological principle known as the biphasic dose response. This means a moderate dose has a positive effect, whilst too much RLT can plateau the benefits, or in some cases create a temporary reversal on the effects. Sometimes your body may need recovery time between treatments, especially in more sensitive individuals.
So essentially, the key to how often you use RLT, is to find your ideal frequency and dosage which will vary from person to person, what your specific health goals are, your individual response to light, the power and wavelength of your device, and the area(s) of the body you are treating.
Typically, the recommended amount of home use is 10-20 minutes per area, 4-6 sessions per week for an initial 4-8 weeks phase. If unsure, please contact us for more information.
How far should I stand from the panel?
For optimum results you should stand 6 inches to 12 inches away from the panel. If you are more sensitive, standing further away is also advised.
How soon will I notice results?
Some people feel temporary pain relief after a few sessions. Skin and performance benefits usually build gradually over 3-8 weeks of consistent use.
Is eye protection required?
For face sessions over ~5 minutes or at high intensity, wear the supplied goggles or keep eyes closed. Never stare directly into bright LEDs at close range.
Can I use Red Light Therapy with skincare products?
Yes - use on clean, dry skin. Apply serums or moisturisers after your session. If you use retinoids, acids or photosensitisers, reduce frequency and patch-test, or check with a clinician.
Will Red Light Therapy aid muscle recovery and physical performance?
Whether you are a weekend warrior chasing personal bests, a pro athlete fine tuning performance, or simply someone who wants to stay strong and active as the years pass, recovery is everything. It is what determines how often you train, how quickly you bounce back from fatigue, and how well your muscles rebuild and re-grow.
In recent years, red light therapy has emerged as a powerful, evidence based tool for enhancing recovery, boosting muscular adaptations, and extending endurance. Unlike supplements or stimulants, which often mask fatigue or come with side effects, red and NIR light tap directly into your cellular biology supporting the body's natural regeneration process from the inside out.
Does red light therapy help boost collagen production?
Red Light Therapy stimulates fibroblasts - the cells responsible for producing collagen and elastin. These proteins give skin its structure, firmness, and bounce.
It can also help acne, scars, rosacea and hyperpigmentation as it calms inflammation, regulates bacteria and supports healing; useful for breakouts, texture and the look of scars. Consistency is key.
Will it help with joint pain?
Yes. RLT is quickly becoming the go-to non-invasive solution for managing and reducing various types of musculoskeletal discomfort. With a growing body of clinical evidence and thousands of success stories it is no surprise that people are turning to light (not pills) for lasting relief.
Who should avoid Red Light Therapy?
Even though RLT is considered safe for the majority, it doesn't mean it's safe for everyone. In certain cases, red light therapy may be inadvisable, contraindicated, or require close medical supervision. If underlying medical conditions or medications come into the mix, the interaction with light may have unintended consequences.
Avoid use over suspected skin cancers, active haemorrhage, or directly over the thyroid without clinical guidance. Consult your GP if you’re pregnant, have epilepsy/photosensitive conditions, or take light-sensitising medicines.
Are there any side effects?
Side effects are rare and mild, such as temporary redness or warmth in the treated area. Overuse at high intensities could cause skin irritation. Eye damage is possible without protection, so goggles are recommended.
How is this different from laser, IPL or sunbeds?
Lasers are coherent light used in clinics; IPL and sunbeds include broad-spectrum/UV and can heat or damage skin. Red/NIR LED therapy is narrow-band, non-UV and non-ablative for at-home use.
