You flip a switch and turn on the lights. Pretty simple, right?
But what if flipping that switch did more than just turn on a light bulb. What if you could flip a switch and receive instant pain relief?
What if that same switch helped with inflammation healing, tissue regeneration, autoimmune health, brain recovery, increased athletic performance, seasonal depression, better eyesight and even relief from painful cancer side effects.
Do I have your attention now?
That switch is a new kid on the block: Red light therapy at home. The truth is, there’s nothing new about red light therapy. It’s been around for almost 50 years but is only recently gaining the traction it deserves.
In the 1990s, NASA used concentrated red light therapy to activate plant growth in space. After seeing the effectiveness, they began researching what applications this could have for people as well. The power of light to literally cure whatever ails you is a real treatment with real results. “The number of conditions red light can treat is ‘continuously expanding,’” said Michael R. Hamblin, PhD, associate professor of dermatology at Harvard Medical School.
But is it too good to be true? Let’s break it down to see what red light therapy actually is, how it helps literally every single person on the planet, and best of all – how you can do it all from the comfort of your own home.
What is Red Light Therapy?
First, let’s just be clear about what red light therapy at home is NOT. It’s not a tanning bed. It’s not a laser. It’s not ultraviolet rays and you can’t get it from the sun.
Red light therapy is a concentrated form of light waves in the red and infrared spectrum. The light emitted in this spectrum is perfectly safe for the skin and poses no risk of skin cancer, sunburn or tanning.
The red light wavelengths go straight to the cellular level, deep inside the body. At this level, it enhances ATP, which is the source of energy in every cell in your body. This means that each cell gets a boost to do its job a little bit better, which can affect almost every system in your body.
How is Red Light Therapy different than sunlight?
Red light therapy at home is completely different than the harsh UV rays of sunlight. While the sun can give you Vitamin D, a sunburn (if you’re not careful) and promote a great day at the beach, red light therapy is actually making a difference at the cellular level of your body. The sun’s rays are actually harmful to the body when used in excess while red light therapy is completely safe with absolutely no side effects.
What Does Red Light Therapy Do?
As you sit or stand a few inches away from a panel of red lights, their wavelengths can actually alter the way your cells produce energy and antioxidants. Because it’s working with the way your body already functions, it has increased efficiency in healing bones, nerves, skin, tendons, and ligaments within the body. Thousands of studies have been done on red light therapy at home and new benefits are being discovered almost every day.
Benefits of Red Light Therapy
Thousands of studies have been done on red light therapy and new benefits are being discovered almost every day. Evidence for the effectiveness of red light is overwhelmingly in favor of both effectiveness and safety. The FDA has approved light therapy for the treatment of joint pain, reduction of wrinkles, and many other conditions.
- Inflammation: A study showed red light therapy to be useful in decreasing inflammation and stimulating post-procedure wound healing.
- Hair and Skin: It can help bolster hair growth in people with alopecia and stimulate collagen production in people who hope to lessen fine lines and wrinkles.It also helps naturally decrease oil production and bacterial levels in your skin with no drying effects or harsh chemicals.
- Soft-Tissue Damage: When it comes to injuries like sprains and strains, red light therapy may both promote healing and offer pain relief as well.
- Pain Relief: The studies and data on red light therapy at home for pain relief is so clear the FDA has approved it as a therapy for treating minor pains and arthritis.
- Wound Healing: A 2014 study found red light therapy promoted “increased tissue repair and healing…[plus] beneficial effects on wrinkles, acne scars, hypertrophic scars, and healing of burns.”
- Muscle Repair: A 2014 study found that the therapeutic technique led to reduced muscle strength loss, less muscle soreness, and fewer range-of-motion impairments for up to four days after exercise. A more recent 2018 study also proved that RLT both before and after exercise reduces knee muscle fatigue.
- Circulation: Studies have shown an increase in circulation in the body which allows the tissues to receive more oxygen and nutrients for internal healing.
- Sleep Therapy: Using a high-quality red light therapy at home during the day has been shown to increase your body’s natural melatonin output, which helps you sleep and stay asleep longer.
- Weight Loss: Some researchers have found red light therapy to be effective at washing away fat cells from the body and control hunger-related hormones.
- Cellulite: A 2011 study on red light therapy shows reduced cellulite in women ages 25-55 when combined with light treadmill exercise.
How Does Red Light Therapy Work?
All things need cell energy to function and survive. Most living things rely on natural light to power this process. Natural light encompasses a wide range of wavelengths and colors, but it’s the red and near-infrared wavelengths that make the difference. By concentrating these wavelengths, you can concentrate their benefits of stimulating the mitochondria in your cells, which is the cellular powerhouse.
Before you get any creative ideas, you can’t just pull out your red Christmas lights and stand in from of them hoping for a miracle. Red light therapy at home must use medical-grade LED lights with a concentrated wavelength. More specifically two wavelengths of red light in particular—660 nanometers and 850 nanometers. These specifications deliver the best biological response.
The former, 660 nanometers, is more quickly absorbed by the skin, making it the go-to for dermatologist and cosmetic treatments, while 850-nanometer wavelengths penetrate deeper into your body to help with muscle recovery, joint pain, and full-body health.
Are There Any Side Effects to Red Light Therapy?
Red light therapy is not UV rays, is not a laser or intense pulse light, and is completely non-invasive. As of today (2019) there are no known side effects of red light treatment. But I might mention that overuse can be a little tiring on the body if you haven’t built up to using it regularly.
How Can I Get the Benefits of Red Light Therapy at Home?
As evidence for red light therapy benefits grows, so does the accessibility of the therapy itself. You can find red light therapy options at the dermatologist, spa, or maybe a fancy gym, but you can also enjoy red light therapy at home. At-home options for red light therapy include masks, hand-held devices, bulbs, and full red light beds.
How to Choose the Right Right Light Device
You can buy a variety of DIY devices, but it’s important to be sure that it specifies a clear output intensity.
Red Light vs. Infrared Light: Most products are marketed as either Red Light device or Infrared Light device. This is not just a difference in wording, but a complete difference in application, so it’s important to know the difference:
- Red Light reaches 600-700 nanometers and is designed for skin and cosmetic treatment.
- Infrared Light reaches 700-900 nanometers and is designed for muscle recovery, joint pain, inflammation, etc.
It’s important to base the device you purchase off of the intended purpose you’d like to use it for. You can use either red light or infrared light and sometimes both. One is not better than another, they simply target different areas. Both can be effective for skin treatment, but infrared light will penetrate deeper to help with bone and muscle health.

Dermashine recommends using the product for 15-30 minutes once a day to quickly and naturally treat many blemishes like scarring, lumpy uneven skin, fine lines, wrinkles, discoloration, large pores, inflammation, redness, dryness, oiliness, and more.
Almost 300 reviewers have given the mask an average rating of 4.1 out of 5 stars. Phylicia said, “When I found Dermashine, I was cautious in reading the reviews as at the end of the day everyone’s skin is different. Having suffered with acne in my teens, I still have scars on my cheeks that I am trying to get rid of. Once I received the Dermashine, I was blown away. I used the blue LED light for 20 minutes then the red LED light for 20 minutes and I honestly saw a difference immediately. My skin looked and felt tighter.”
Some reviewers commented that the mask felt heavy, but this doesn’t interfere with effectiveness, and even just 5-10 minutes can make a big difference. This makes it easy to recommend the Dermashine LED face mask, you can read more reviews or order the product on Amazon.
How to Use a Red Light Therapy Device at Home
Because the technology is still new and the effects are constantly being researched, the jury is still out regarding the exact dosage needed for an optimal effect. What we do know is that there is no fear of overdoing it because there have been no side effects. It’s almost impossible to cause any harm so long as the bulbs are in working order. Start with 5-10 minutes and work up from there. You can use the device every day or even several times a day. You will see more benefits from consistent use.
Every device, due to the different levels of intensity and recommended exposure for the area you want to treat, will have their own directions on how to best use their device. Please read your manual for the best results when it comes to treating the internal issues. But there are a few guidelines I would like to recommend when it comes to treating the skin.
- How to treat the skin surface?
- For skin aging and pigmentation, look for wavelengths near to either 610 to 630 nm or 670 nm.
- How close should the light be from your skin for best results?
- Depending on your light, position it so that the light hitting the skin is between 20 mW/cm² and 200 mW/cm². Highest results are under 100 mW/cm².
- How do you use the red light to treat acne?
- A slightly higher intensity of red light seems more appropriate for severe cases of acne, for up to 10 minutes every day.
- Depending on the device, the distance would be around 10 cm or less with one of the more powerful units. Treating acne treatment involves reducing skin inflammation, but also sterilizing the acne bacteria. Red light has a photodynamic bactericidal effect on certain bacteria, including acne bacteria, due to a photosensitive pigment they have. The photodynamic effect is dose dependent, meaning more is better.
- How about to treat general skin aging or pigmentation?
- It has been suggested to use a relatively moderate light intensity exposure, but for a longer time. This might range from a 50 to 100 mW/cm² light intensity. Results tend to be worse if you go for short intense sessions.
- Use for 5-15 minutes, four times a week.
- What about for treating hair loss?
- Because hair loss doesn’t have the root cause at the scalp you should be using light on other areas—like the thyroid, for example, as well as the scalp.
- Use fairly high power densities, 50 to 100 mW/cm² or more.
How Long Should Each Treatment Be?
Closer and longer treatments are better in certain conditions such as infections, but otherwise, a more moderate dose is better. Five to 15 minutes is all that is usually necessary.
The weaker devices out there might need 20 to 30 minutes or more. If you can’t find information on a device’s power density, in mW/cm², and how that changes by distance, I would be skeptical whether it is useful at all.
Just remember – the closer the device to your skin the deeper the treatment will penetrate.
Everyone from soccer moms to Olympic athletes are discovering the benefits of red light therapy. Most often it’s used for joint pain, inflammation, physical performance and skin health. Imagine what red light therapy at home could do for you.
