10 Mistakes You Might Be Making Using Red Light Therapy At Home

Until recently, red light therapy was only available in spas and clinics. Now, personal red light therapy devices are making the treatment both more affordable and convenient for consumers. Unlike many other health treatments, red light therapy is safe to use every day, is non-invasive, and has virtually zero risks and side effects. This means that you don’t need a trained professional to administer the treatment - you are completely in charge. That said, there are a few mistakes you may be making when using red light therapy at home.

Given that the treatment is basically idiot-proof, these errors are generally not harmful or damaging (except potentially #9). However, they may keep you from fully optimizing your treatment and thus from getting the full benefits. Here are 10 things you might be doing wrong when using red light therapy at home, and how to easily fix them.

From a Rouge customer: I use it every second day and after just two weeks I began to see the difference, my skin is tighter with more radiance! The only thing I regret is not getting it earlier! Absolutely love it!

1. Being inconsistent with your treatment

The biggest advantage of using red light therapy at home is the ability to use it daily without incurring the extra costs that professional treatment would entail. However, if you’re not using your device the recommended 3-5 times a week, you’re essentially squandering your investment - and the potential benefits.

2. Wearing clothes or sunscreen

Just as clothes block UV light from penetrating your skin, it will block red and near-infrared light as well. As for sunscreen, it’s designed to block UV light, but it will also work as a barrier to some red and NIR light, preventing it from penetrating as deeply. And for those who wear makeup, take note that many foundations contain SPF. If yours does, you might consider using red light therapy in the morning before applying makeup, or after washing your face before bed.

3. Sitting too close or too far from your device

The guidelines for how far to place yourself from your device are not yet perfectly honed, so it might take a bit of guesswork and trial and error on your part. Generally, for skin issues, it’s recommended to sit between 12-36 inches from your device, and for issues involving deeper tissues, 6-12 inches is advised.

4. Making your sessions too short or too long

The general rule is to have your sessions range anywhere from 10-20 minutes, but you can play around with this too. Every body is different, after all, and reacts to treatment in its own way. You’re likely not going to see results if you keep all your sessions to 5 minutes. However, if every once in a while that’s all you have, by all means, 5 minutes is better than none.

As for longer sessions, you might be tempted to try to cram more minutes into a session or to pack a week’s worth of sessions into one. While this isn’t necessarily harmful, red light therapy simply doesn’t work that way. Hour-long sessions won’t be more effective than 20-minute sessions, and will actually reduce the effectiveness of the treatment if it means you’re skipping sessions.

5. Using the wrong red light or Near-infrared light setting

Red light and near-infrared (NIR) light have different functions. Red light is effective for skin issues, hair growth, and wound healing. NIR, on the other hand, penetrates deeper and is mainly used for conditions such as pain relief, muscle healing and recovery, and cognitive health, to name a few.

Your Rouge Red Light Therapy device has three settings: red light, NIR light, and dual. You can toggle from one to the other using the ‘mode’ button. Make sure you have it set to the right mode before starting your treatment. As a failsafe, there’s no harm in using the dual light mode, as using both doesn’t diminish the strength of each type of light. In fact, not only is there no harm, you might even see improvements in areas you didn’t even know needed improving.

*Note: you might be wondering why it looks like half the lights on your device aren’t working. Don’t worry, that’s normal. Those are the NIR lights. Near-infrared light is not part of the visible light spectrum, so it’s invisible to the naked eye.

6. Not staying hydrated

Drinking water throughout the day is good advice regardless, but there is new evidence that it may help with the effectiveness of red light therapy. Researchers propose that red light therapy may prefer hydrated cells, as they tend to have more energy stored. While more research is needed to determine with certainty whether this affects treatment IRL, it’s never a bad idea to reach for that glass of water.

7. Using the wrong size device

Rouge offers red light therapy panels in various sizes to accommodate a range of needs and budgets. We’ll be honest, we think everyone should have a Rouge Ultimate in their home as it can tackle the big issues and the smaller complaints at the same time. However, we know that’s not a possibility for everyone, and is not essential if your main goal is alleviating arthritis pain in your hands, for instance, or improving your facial complexion. Keep in mind, though, that for full-body issues such as fibromyalgia or conditions involving large body parts like chronic back pain, a larger panel will provide more efficient treatment, allowing you to see results quicker, and to spend less time in front of your device.

8. Not tracking your progress

Given that it’s a process that can take time, red light therapy results can sneak up on you. Let’s say you’re using red light therapy to improve your skin’s appearance. Given that you see your face in the mirror every day, it might take someone pointing out how radiant you look or asking if you’ve had work done for you to take notice of your progress. The same goes for chronic pain. You may not even realize your pain is decreasing until one day you’re able to climb stairs without using the handrail or lift a box without flinching.

For cosmetic issues, you might consider taking progress pics. For invisible issues such as pain or immune health, a journal might help you keep track of improvements. Not only will this help motivate you to keep up your treatment, it might also be useful for adjusting the frequency and duration of your sessions to find the regimen that works best for you.

9. Not discussing your red light therapy treatment with your doctor or health care professional

While red light therapy is known for being completely safe, painless, and non-invasive, it’s always a good idea to talk to your doctor, physiotherapist, or other health care provider before starting any sort of treatment plan.

This is particularly important if you’re pregnant, or if you’re undergoing certain treatments already. Some medication, for instance, can increase your photosensitivity, which can lead to temporary redness and tightness in the skin after using red light therapy.

Your doctor or healthcare professional is your ally when it comes to your health, and they should be kept aware of any and all aspects of your life that might affect your wellbeing. The more they know, the better they can do their job.

10. Expecting immediate results or a cure

While red light therapy might be the most promising treatment to date for a whole host of issues, it’s important to manage your expectations. First, it’s not a miracle cure. In fact, one of the reasons consistent and frequent use is so important is that once treatment stops, the issue is likely to return after a time.

Second, red light therapy is a process. Like so many things that are worthwhile, it takes patience and dedication. If you feel like you’re not seeing results after a month, don’t freak out. While there might already be a lot of action happening behind the scenes at the cellular level, it can take a while to build collagen, heal damaged tissue, and stimulate stem cells.

The Bottom Line

There are no grave mistakes with red light therapy. However, small missteps or oversights can potentially alter the effectiveness of your treatment. The key is recognizing them and making the necessary adjustments.

And sometimes it’s just a matter of listening to your body and fine-tuning your sessions to optimize your body’s own unique healing potential. With red light therapy, you’re in control of your device, and your health.

  • Can I use a infrared lamp on my foot, after an ankle replacement?
    After neck surgery with prosthesis?
    Thank you.
    Rouge Canada replied:
    Hi Annina, Thank you for your comment! It is considered safe on prostheses. Red light therapy, has been used in joint replacement rehabilitation and to relieve post-operative discomfort. Any type of implant will not be affected by red light therapy which is often used to address potential complications from post-implant surgery simultaneously such as post-surgical scars and edema. We actually covered this topic in another blog post you are more than welcome to check out. The blog post is titled: Red Light Therapy and Surgical implants. Check it out to learn more. I hope this helps, let me know if you have any questions.

  • Should you do two sessions to get the whole body with a 36” panel. So to do whole body you would do 4 sessions?
    Rouge Canada replied:
    Hi Sandy, Thank you for your comment. 36 inches tall is a nice length for body coverage, depending on your height as well. One of our panels measures 27 inches and can irradiate just over half the body. You could do two sessions for full body coverage depending on your height. One session can be on the front of the body for 10-15 minutes, then you can turn over for the back. Please do keep in mind that the closer you are, the shorter your session will be and you will cover a smaller surface area. Maybe standing further away will help get that full body coverage and you won’t have to do a full 4 sessions to aim for full body and lengthen your time to 20 minutes. with that said, If you stand further away, you will be able to cover a larger area. Remember that we need to give the treatment area a certain amount of energy, as we move away from the light the energy available to our body diminishes rapidly. Another option can be to connect two panels together if you are quite tall. Hope this helps! We wish you the best of luck in your wellness journey!

  • Hi Debra, using both red light and NIR can achieve very similar effects but the NIR will penetrate deeper levels, with that said, NIR may be best for your condition. When it comes to how long and how often, 20 minutes is an ideal treatment time, consistent use is recommended as well. We wish you the best of luck in your health and wellness goals!

  • Hi I want my red light panel to address both skin and deeper issues, such as inflammation processes, arthritis, metabolic stimulation, brain fog. To address both deep and superficial issues, do I stand close so that there is deeper penetration? Will that at the same time address my skin collagen goals? Thank you!
    Rouge Canada replied:
    Hi Mischa!
    Thank you for your comment, the great thing with our red light panels is the two available wavelengths that have been shown to treat the superficial and deeper issues, Red light and NIR. Most people like to use them in conjunction with each other for optimal treatment. We use a 660nm wavelength for all of our devices. It is a shorter wavelength, widely used in research and clinical settings. This wavelength is short which means it hits the surface of the skin and penetrates about 1-2mm below the skin’s surface. Meanwhile, NearInfraRed (NIR) light is nearly invisible to the naked eye, and it penetrates deeper below the skin surface, 2 to 3mm. To answer your question in regards to distance to light: we need to give the treatment area a certain amount of energy, as we move away from the light the energy available to your body diminishes rapidly. Red light therapy is not a one-size-fits-all, standing close will allow for deeper penetration. We like to recommend a 15-20 minute treatment time for most treatment areas (6 hours apart for each treatment session). I hope you find this helpful! We wish you the best in your wellness goals!

  • Hello Rouge Care,
    Is it more beneficial or necessary to do both sides of our body (front and back) during our red light therapy sessions?
    Thank you.
    Rouge Canada replied:
    Hi there! Yes it is definitely beneficial to do both sides of the body; by doing both sides, you are keeping the skin benefits consistent and also giving your body the deeper penetration from the NIR light from both sides.
