What if you could narrow down your red light therapy research into three decisions. You can quickly become a red light therapy expert by mastering just three things: the condition, the light color, and the device type.
The three questions to answer when buying a light therapy device are:
- What am I treating?
- What color lights treat that condition?
- What type of device fits that body part?
Studies have repeatedly found that light therapy improves many conditions, including these:
- Arthritis (Inflammation and Joint Pain)
- Canker Sores
- Cognition (Addiction, Alcoholism, Anxiety, Autism Irritability, Cognition Decline, Dementia, Depression, PTSD, Stroke, Traumatic Brain Injury, Parkinson’s)
- Fat Melt (Fat Release, Reduction in Body Size, Reduction in Blood Cholesterol)
- Herpes (Shingles, Post Herpetic Neuralgia)
- Frozen Shoulder
- Tendonitis (Carpal Tunnel, Soreness, Weakness)
- Diabetic Wounds
The most successful colors are:
- Red and infrared treat aging, inflammation and pain.
- Blue light is essential for treating acne.
- Green light for wounds and migraines
The devices you can buy include:
- Face Masks
- Face Domes
- Handheld Panels
- Handheld Wands
- Handheld Torches
- Knee Massager
Use the guides below to narrow down the COLOR LIGHT for your condition and the DEVICE TYPE that fits that part of your body.

Pros and Cons of Red Light Therapy Panels
A light therapy panel is a box ranging from 5 inches to 4 ft. high. It sits on a desk or hangs on a wall or from the ceiling. The intent is to get light to a large part of your body.
The light reaches a good part of the body. The bigger the panel, the more body it reaches.
Panels usually run on 110v electricity and have fans. These two factor into the panel outputting electromagnetic fields (EMFs) that might be unhealthy. Vendors will usually brag that their devices have “zero EMF.” Check if the distance of that claim. Everything is zero EMF at 6 inches. Can you hold the device on your skin, at zero inches away, without exposure to harmful EMFs? Everything is safe at 6 inches away. That doesn’t make it zero EMF.
Panels waste photons to reflection and distance. If you hold the panel to your body, you can solve both these issues. However, you then expose yourself to potentially unhealthy EMFs. That is, unless the panel does not emit EMFs. To achieve this status, get a battery or USB operated panel such as the Spazer and SAIDI at GembaRed.com.
Pros and Cons of Light Therapy Face Masks
Light therapy face masks usually target acne, aging, or both. They sit over the face. Either a set of eyeglasses hold the mask on your ears, or a band holds it around your head.
Face Mask Pros
Face masks can more easily target facial issues than other devices. They are hands free. Face masks delivery most of the light they output their coverage minimizes reflection. The light is right next to the face so you don’t lose photons to distance.
Face Mask Cons
Some masks are heavy and uncomfortable. You can’t put cotton at the edges to relieve the discomfort. If a mask’s marketing says it comes with seven colors, skip to the next vendor. We don’t have scientific evidence for seven colors of light therapy. What is much more likely happening is that the mask creates the illusion of secondary colors. Rather than showing purple light, for example, it shows red and blue at the same time. This creates the illusion of purple, but it is not the purple wavelengths. It is the red wavelengths and the blue wavelengths. They are both healing, but they are not purple.
Facial Domes Pros and Cons
A dome is a rigid half circle or a pliable pad that creates a dome when places into a holder. The lights are on the underside and shine down on the face. You can use a dome on other body parts but it is usually narrow enough to fit only over an arm or so.
Domes offer targeted therapy to the face without the discomfort of a mask. The material does not touch the face, and you are not wearing it the way you wear a mask.
When you are under a dome, you need to relax and maybe listen to something. You don’t have the ability to walk around or read. This is true of panels, too, but I didn’t mention it under panels. The reason is, face masks are more portable, compared to domes. Domes are more comfortable. You lose a bit of the photon quantity to reflection and distance, as the dome is several inches from your head.
Handheld Wand and Torch Light Therapy Pros and Cons
A handheld light therapy wand is a light you can hold with one hand. They are “wands,” or just “handheld” lights. A torch light device looks like a small flashlight.
Wand and Torch Pros
Wands and torches allow you to treat anywhere on the body with light therapy. So long as you’re not working on your face, you can open your eyes to watch TV or read during treatment.
Wand and Torch Cons
Wands and torches are handheld, so at least one hand is busy during treatment. They don’t attach to the body so you have to hold them in place during the session. Battery operated wands and torches are portable, while plugged in versions are not.
Pad Light Therapy Pros and Cons
A light therapy pad is a rubber-like pliable pad with lights on one side. You place the pad on the area you want to treat. If you use the pad to make a facial treatment dome, you put the pad in a holder that allows you to shape the pad into a dome.
Pads feel nice to the touch. You can use some nylon and Velcro to hold a pad in place. You can wrap pads around your legs, arms, and body. You can wrap the pad around the area to treat and then read or watch TV. Because you press the pad onto your body, the pad is one of the most efficient light therapy systems.
Battery powered pads are portable but plugged in pads are not.
Wrap Light Therapy Pros and Cons
A light therapy wrap is a neoprene fabric with LEDs embedded into a section. Wraps usually have a Velcro type closing system so you can wrap the light around a leg, arm or waist.
Wraps don’t lose photons to reflection and distance. They output photons that reach the skin right away. Battery powered wraps are portable while plugged in wraps are not. Battery operated Wraps are usually EMF free. You can buy wraps designed to fit on elbows, wrists and knees, as well as flat wraps that fold around any part of the body.
Cord powered wraps emit EMFs that might you sick over the long term. Wrap LEDs have a higher fail rate (in my experience) than other device types. Wraps are great for targeted treatment; just ensure you get a solid company and warranty. Face therapy is difficult with a wrap.
Knee Massager Light Therapy Pros and Cons
A knee massager looks like a helmet that straps to the front of the knee. Not all devices are massagers, but usually they have both massage and LEDs. The purpose of the device is to offer targeted therapy to arthritis and tender knees.
Knee Device Pros
Knee devices output light directly to the knee without losing photons to distance or reflection. The massage device can be therapeutic and help reduce pain. The device offers targeted treatment to the knee. When battery operated, knee devices are portable
Knee Device Cons
It’s not easy using a knee device on other parts of the body. When cord operated, knee devices are not portable.
Wrist Light Therapy Pros and Cons
A wrist light therapy device sits on the arm where you wear a watch. It’s just bulkier than a watch. The intent is usually not to treat the wrist (for repetitive motion strain, for instance) but to stimulate acupuncture points related to blood pressure. This device design was on the market for a couple of years but is not available anymore.
Belt Light Therapy Pros and Cons
A belt device is a portable set of lights that you wrap onto your body with a strap and a Velcro like closure. A belt is somewhat similar to a neoprene wrap except that wrap lights are embedded into fabric, and belt lamps are individual units that string together between two pieces of fabric.
The Belt device delivers light to the target without losing photons to distance or reflection. A well-designed belt wraps around the legs, arms, back or tummy and stays on with a Velcro type of attachment. A belt with rechargeable batteries is portable. You can read and watch TV while using the belt.
Belts that use fans emit high levels of electromagnetic fields (EMFs) that might be harmful over time. Belts that plug into the wall are not portable. Face therapy is difficult with a belt.
Bulb Light Therapy Pros and Cons
A therapy bulb is a large light bulb with LEDs embedded in the front, that screws into a standard light socket.
Bulbs are one of the cheapest ways to get light therapy. If the bulb does not emit EMFs, you can hold it on your skin to avoid losing photons to distance and reflection.
Light therapy bulbs are often too heavy to use in even the strongest gooseneck lamp holders. If you put a therapy bulb in a flexible floor lamp, the weight might pull the arm downward. If the bulb emits EMFs, you want to stay at least 3 to 6 inches from the device.
“Eyeglasses” Light Therapy Pros and Cons
The Eyeglass therapy device looks like a pair of glasses. It delivers light to the brow, eye and under the eye.
If this device comes with eye protection, then the pros are that it delivers light to the target without losing energy to distance or reflection. However, many lights with eyeglass design do not come with goggles or eyeshades. Blue light is definitely dangerous, and infrared light is dangerous over the long term. A device called Re-Timer, for example, emits blue light directly into the eyes. This is a terrible idea and should be banned.
Hair Regrowth Helmet Pros and Cons
Hair regrowth and brain therapy helmets are lined with LEDs to target the scalp, neck and sides of the head. Red light therapy can regrow hair for men and women with several types of baldness. When used for brain therapy, it’s best of the user does not have hair that absorbs the photons. Some people shave their heads when using helmets for brain therapy.
Hair Helmet Pros
A hair helmet delivers light to the hair, which can absorb it without energy loss to distance or reflection. The hair is good at absorbing red light. Dormant follicles can be awakened using helmets. Battery operated helmets are portable.
Hair Helmet Cons
Helmets can be (but are not always) heavy. A helmet has to be large enough to reach areas of dormant follicles. When using the helmet as a brain device, it’s best not to have hair in the way.
Brain Light Therapy Helmet Pros and Cons
A brain therapy light helmet is lined with LEDs. To get to the brain, these light must power through skin, blood, bone, and possibly hair.
Brain Helmet Pros
The brain helmet delivers photons to the scalp, neck and the sides of the head.
12 to 15% of infrared and 2 to 4% of red light penetrates the skin, blood, water and bone between the light and the brain. Studies show that this is sufficient to help traumatic brain injury, stroke and dementia patients. You can use a brain helmet as a hair growth device, but the hair will block the majority of the light from reaching the brain.
Brain Helmet Cons
The fact is that only a small portion of scalp light makes it to the brain. To ensure best penetration, the target area should be bald or shaved.
Hair Regrowth Brush Pros and Cons
A hair regrowth brush is a handheld red light designed to stimulate hair regrowth. The light awakens dormant follicles for people with many types of baldness or thinning hair. You don’t “brush” the hair as you would with a grooming brush. You lay the brush on the hair and let it sit for the instructed time, and then move it to the next spot.
Hair Brush Pros
A hair brush can be significantly cheaper than a hair regrowth helmet.
Hair Brush Cons
You need to hold and operate the brush as instructed, which can be a bit tedious over the length of the treatment period.
Light Therapy Bed Pros and Cons
A light therapy bed or pod is a whole-body light box similar to a tanning bed. In theory, it’s a whole body treatment with healing light. Until I can assess the non-natural EMF status of these beds, I reserve comment.
Light Therapy Nasal Devices Pros and Cons
Shining light up the nose looks silly, but it has one of the most profound healing effects of all light devices. That is because the nose is the most direct route for light to reach the brain.
Nasal Therapy Pros
Nasal therapy sends light to the brain without the hair and skin barriers found on the scalp. The light is no more than 3 inches from the brain when inserted in the nose. While 810 nm light can penetrate the scalp to the brain with sufficient power, the nasal passage requires comparatively little power to direct light to the brain’s ventral area. That light does not have to have the deepest penetration ability (810 nm), and so multiple wavelengths can penetrate the ventral area through the nose with therapeutic success.
Nasal Therapy Cons
Nasal light therapy looks silly.
