Red light therapy at home: a beginner's guide for UK buyers
Red light therapy has moved from physio clinics and elite sports teams into living rooms across the UK. Devices range from palm-sized handhelds to panels as tall as a door, and the marketing can be confusing. This guide explains what red light therapy is, what the research actually says, and how to choose and use a device at home.
What is red light therapy?
Red light therapy is the use of specific wavelengths of red and near-infrared light, usually from LEDs, shone onto the skin. In research it's often called photobiomodulation (PBM). Unlike a tanning lamp, it doesn't use ultraviolet light, and unlike a heat lamp it isn't designed to make you hot.
Most home devices use two bands of light:
- Red light, around 630 to 660 nanometres (nm), which you can see as a deep red glow.
- Near-infrared light, around 810 to 850nm, which is mostly invisible and reaches deeper into tissue than red light.
What does the research say?
Photobiomodulation has been studied for decades, and the research is growing quickly. The most researched area relevant to home users is exercise performance and recovery. A 2018 systematic review and meta-analysis in Lasers in Medical Science pooled placebo-controlled trials and found some benefit of red and near-infrared light on measures such as time to exhaustion and number of repetitions, while rating the overall quality of evidence as very low to moderate (Vanin et al., 2018). We look at this in more detail in red light therapy for muscle recovery.
The honest summary is that results are encouraging in some areas, but studies vary a lot in the devices, doses and people they use. Red light therapy is not a cure for any medical condition, and if you have a health concern you should speak to your GP.
Why people use it at home
- Training recovery: a short session before or after exercise as part of a recovery routine.
- Targeted areas: using a belt or handheld on the back, knees or shoulders while relaxing.
- Skin and face: a gentle daily session with a compact panel.
- Wind-down: many people simply enjoy a calm 10 minutes in the warm red glow in the evening.
Types of home device
Handheld and wearable
Portable devices such as the cordless Aura Mini and the hands-free Auracell belt are ideal for treating one area at a time, at home, at the gym or while travelling.
Compact panels
Desk or door-mounted panels such as the Aura Pro 300W and A60 cover the face or a single body area per session, and suit most beginners.
Half and full-body panels
Larger panels in the A Series and S Series cover more of the body at once, so you can do your whole routine in one 10 to 15 minute session. Our panel buying guide explains sizes in detail.
How to use a red light device
- Bare skin: light can't get through clothing, so expose the area you're treating.
- Distance: most panels are used 15 to 30cm from the skin. Closer means more intense; follow your device's guidance.
- Time: start with around 10 minutes per area. Most manufacturers recommend 10 to 20 minutes.
- Frequency: three to five sessions a week is a typical routine. Consistency beats marathon sessions.
- Eyes: always wear the goggles provided and never stare into the LEDs.
What to look for when buying
- Wavelengths: look for clearly stated red (630 to 660nm) and near-infrared (810 to 850nm) wavelengths.
- Coverage: buy for the area you actually want to treat, not the biggest number.
- Build and safety: low EMF, flicker-free LEDs, timers and proper certification such as CE and RoHS.
- Support: a UK warranty and a team you can contact if something goes wrong. Every device we sell comes with a 3-year UK warranty.
Common beginner mistakes
- Using it through clothing or with thick moisturiser or sunscreen on the skin.
- Sitting too far away, which spreads the light much more thinly.
- Expecting overnight results. Give a consistent routine several weeks.
- Skipping eye protection because the light looks gentle.
Who should check with a doctor first?
Speak to your GP before starting if you are pregnant, take medication that makes you sensitive to light, have a history of skin cancer, epilepsy triggered by light, or any other medical condition.
Frequently asked questions
Does red light therapy feel hot?
Most people feel gentle warmth rather than heat. It shouldn't be uncomfortable. If it is, move further away.
Morning or evening?
Whenever you'll do it consistently. Many people slot it in after training or as part of an evening routine.
Can I use it every day?
Many people do short daily sessions, but follow your device's instructions and start gradually.
