How to Use Red Light Therapy at Home + Anti-Aging, Skin-Healing Benefits

Red light therapy treatments are popping up all over the place lately, and there’s a reason for it. It’s an amazing non-invasive treatment for many health and skin issues that is backed by solid research.

Scientists are finding that red light therapy, or low-level light therapy (LLLT), can diminish and even reverse the signs of aging without any side-effects!

This might sound too good to be true, but it’s really not. If you want a risk-free way to get youthful skin, then red light therapy is the way to go.

Guys, this isn’t just some fountain of youth mumbo-jumbo.

We HAVE a red light therapy machine that we purchased after extensive research on the subject.

While we all love beautiful skin, LLLT can have the same healing effects on the rest of our biology. People are loving it for its ability to…

  • repair soft connective tissue,
  • decrease inflammation and swelling,
  • reduce the side effects of radiation and chemotherapy,
  • and decrease the time it takes for wounds to heal (1).

What is Red Light Therapy?

Low-light, red lasers emit wavelengths through the skin that cause the body to generate collagen, increase blood flow, and help tissue to heal on a cellular level. Its medical applications have been used for over 50 years with extraordinary results and no side-effects.

Many studies have been done that show just how effective red light therapy is on both the body and the skin (2). There have been absolutely no cons to using it that scientists can find, other than that it hurts your eyes if you stare directly at the light box for too long (which we don’t recommend).

You can wear goggles while using it or just simply keep your eyes closed.

How Does Red Light Therapy Work?

The specific red light used encourages cells in the body to produce more adenosine triphosphate (ATP). This amazing little molecule acts like a rechargeable battery in the cell.

As you sit here reading about the wonders of red light therapy, your body is burning through billions of energy molecules. ATP molecules stand at the ready to get to work and give you the energy to do everything from blinking your eyes to breathing.

It also helps skin cells to repair and rejuvenate by penetrating deep into the skin to stimulate circulation and nourishment.

Is Red Light Therapy Safe?

The answer to this question is an emphatic yes! It’s safer than anything else out there right now. Here are a few reasons why:

  • It’s drug and chemical-free.
  • No needles or knives are used (thank goodness!).
  • It’s painless and can be used on all skin types.
  • Children and even babies can receive its benefits, as long as eye protection is used.
  • There are no adverse short-term or long-term side effects.
  • It’s FDA-approved.

It’s safe enough now that the technology isn’t just available at the spa or dermatologist, but is also available for home-use with personal red light therapy machines like the Joov.

The Joov is what we purchased after extensive research, and it comes in a few different sizes depending on what your needs are. If you are mainly looking to improve the look of the skin on your face, the smallest size would be ideal. If you want it for more of the deeper tissue benefits, a larger machine would be ideal for you.

Benefits of Red Light Therapy on the Skin

1. It helps repair sun damage.

As glorious as a tan looks, basking in the sun can cause quite a bit of damage to the skin. The sun’s light rays damage the elastin in the skin cells, which leads to age spots and wrinkles later in life.

Red light therapy will stimulate collagen and bring nourishment to the damaged cells, healing crepey skin and lightening age spots. It’s also shown to prevent skin cancer that might be caused by too much sun (3).

2. It rejuvenates skin, smoothes skin tone, and reduces wrinkles.

red light therapy for increased collagen and healthier skin

One of the reasons we get wrinkles as we age is because our skin loses collagen. Collagen is also responsible for how our skin feels.

A study in the journal Photomedicine and Laser Surgery showed that LLLT “improved skin complexion, improved skin tone, improved texture/feeling, reduced skin roughness, reduced signs of wrinkles and fine lines, and increased collagen density as measured through ultrasonographic tests.” (4)

What’s not to like about that?

You can take collagen supplements these days, but they don’t actually cause your skin to produce more collagen like red light therapy does.

3. Puffiness and swelling are reduced.

Red light therapy stimulates lymph system activity which will have the effect of getting rid of swelling, both short-term and long-term.

It can help heal swelling from an injury but also get rid of the bags under your eyes by reducing fluid retention. If you engage in regular rigorous exercise like weight lifting that leaves the muscles sore afterward, red light therapy can help ease this soreness.

4. Say goodbye to acne, psoriasis, and eczema.

Infrared light is known to be amazing for decreasing inflammation, so of course it works great on skin conditions that are a result of a wonky immune system.

Paired with the shorter red wavelengths in LLLT, it also heals the skin surface, decreasing the likelihood of scarring once the condition clears.

Red light therapy causes the body to produce more vitamin D, a vitamin that most people are deficient in. If we don’t get enough sunlight, we usually have a shortage, which is known to cause eczema and psoriasis.

The irony of it all is that the more sun we get, skin issues like acne will usually clear up because of the vitamin D we absorb from the sun’s rays, but too much sun can cause skin damage.

When used in conjunction with blue light, it will even kill the bacteria that causes acne. Red light therapy is a much safer way to get the skin-healing benefits of the sun without all the negative effects of sun damage.

5. Red light therapy treats and prevents cold sores.

Cold sores love to grace us with their presence at the worst possible moments. Many a wedding photo and prom picture have been photoshopped because of an ill-timed breakout.

Cold sores usually pop up when the immune system is overworked; stress and illness are the two biggest culprits. Creams can clear up a sore, but it can take anywhere from one to two weeks. Red light therapy can cut that healing time in half.

It’s also thought to heal the issue permanently over time, although more study needs to be done to confirm it.

6. Circulation is increased. 

You already know now that it helps the body produce new collagen, but it also increases circulation. This has a huge impact on skin tone and gives our body’s natural defenses an extra boost.

The increased circulation, along with its anti-inflammatory benefits, does wonders for both the skin and inflammation caused by conditions like arthritis.

7. It speeds up wound healing for cuts, burns, abrasions, and bruises.

Fun fact; LLLT was originally used by NASA for wound-healing in space. Our astronauts can boldly go where no man has gone, injury-free, and look good while doing it.

Bruises are caused by blood leaking into the skin tissue when we get injured or have broken capillaries. If there’s no place for the blood to exit the skin, then it pools and causes a bruise.

Red light therapy delivers nutrient-rich blood to the area which will help create new capillaries and repair the damage. It does the same thing for cuts, scrapes, and burns.

8. Dry, flaky skin is a thing of the past.

The increased nutrients and circulation quench thirsty skin. Good blood supply to the surface of the skin creates a hydrating effect.

The oil and sweat glands are stimulated, which creates a barrier on the skin that will keep it hydrated. Don’t worry, though! The extra oil won’t normally make you break out.

It also stimulates fibroblast activity, which is going to give you nice, firm skin without the dryness.

9. It’s an effective hair loss remedy.

Hair loss as we age is a big beauty issue for both women and men, so this is great news! Studies show that infrared light has a significant impact on hair thinning and can stop it in its tracks (5).

Just like with the rest of the body, increased circulation and nutrients stimulate the hair follicles to grow more hair without drugs or surgery. It improves density and thickness in just a few months.

They even sell red light therapy helmets specifically to improve hair growth and thickness. You can wear it while working, folding laundry, etc.

10. Scars and stretch marks fade.

We can get scars from injuries, but more often than not, scars on the face are caused by acne or picking at pimples. LLLT not only fades the discoloration from scarring but improves the texture of skin when collagen fills in acne pits.

Stretch marks are caused when we have a growth spurt or gain weight, and boy are they hard to get rid of! Fortunately, red light therapy can flatten out the scars and fade them over time.

11. Red light therapy reduces cellulite.

Now you can finally throw away all those cellulite creams and massage wands that don’t work because LLLT is proven to reduce body circumference measurements (6).

It also fights cellulite by improving skin texture and lymphatic drainage, which is a big culprit in the formation of fatty deposits.

Be wary of spas that claim that red light therapy burns calories. It has no known effect on your metabolism. Its ability to shape the body and thin the fat layer in the skin is probably due to the lymphatic drainage, which reduces swelling in the area.

The lymphatic system is an important part of our immune system that helps carry waste out of the body, so we get detoxification as part of our cellulite busting session, which is an added bonus.

Researchers also suggest that getting regular massages along with infrared treatments will produce the best results.

12. It removes facial redness without damaging skin.

Rosacea is a rough condition to have. Heat, exercise, and stress can all trigger it. On top of the red, inflamed-looking skin that rosacea causes, the bloodshot eyes that go with it are a bummer.

Red light therapy can reduce the flushing, heal the inflammation that causes pain, repair broken capillaries, and increase the skin’s ability to heal itself. It might take a little longer than other treatments, but the results are safe and pain-free.

People often see improvements in about two weeks, and with regular treatments, the results can be permanent

How to Use Red Light Therapy at Home

We did the math on whether it would be more affordable to go to red light therapy sessions (they have them at dermatology offices and even tanning salons) or to just buy a red light therapy machine.

Ultimately, buying a machine won out as the more affordable option. We looked into different machines and ended up settling on the Joov. It had great reviews and came recommended from other websites that we trusted.

You’ve also got a few options with the Joov because you can get it in various sizes.

They have the mini, original, and the max.

The Mini is pictured in this article. We ended up going with the Max and the “Combo” wavelengths after doing some extensive research into red light therapy.

If you want to try out the Joov today, you can use the coupon code “AVOCADU” to get $25 off your purchase!

There are also smaller versions available to purchase on Amazon, but make sure you dig into the reviews from any of these companies to ensure that they are using the right technology and not a weaker form of the light.

I recommend against a handheld red light device because your entire face can’t absorb the benefits at once. The benefits that you receive from 5 minutes of a larger device like the Joov will take you a half hour or more from a handheld due to the limited surface area it covers.

  1. Hi Lauren!
    I have to say that the Joov intrigues me, and I’m glad I saw this post. I’ve been battling tendinitis in my feet and ankles; I purchased the TENDLITE® in hopes that it would help. I’ve been using it for awhile, and I can say that it actually helps reduce pain, and is supposed to help improve circulation. But, here’s the downside: It’s so small. You have to move it from spot to spot for a minute at a time. It takes sooooooo long to do one treatment, because I have to do the whole top of each foot and my ankles. I plan to check on Joov, since it covers more area at one time. Thanks for the article and the info.

    1. Just randomly came across this blog. It sparked some interest so I checked it out. Let me start by saying I am a doctor and have been apart of the design and development of one of the most impressive light/laser devices in the planet currently used by the US Olympic team members and other high end athletic team and other high end athletic teams/organization. I could go on about my experience in the industry of light therapy…but at the end of the day there are legitimate players and quack job jokers, and unfortunately more of the later. Upon coming across this article title I figured I would run into another promo of a new quack job device. BUT, I was pleasantly surprised and pleased to see Avacadu using and promoting the benefits of Joov. To put it bluntly, Joov is BY FAR the best light therapy device for the money on the planet! Joov was NOT the company I was apart of, the company I was with was geared to commercial use…but Joov (better suited for home use) meets and in some cases beats the pure therapeutic needs of the user. Great job Avocadu for doing your due diligence.
