In the weeks that led to this review, I figured out whether Red Light Therapy actually works. We took the time to dig deep and really investigate, examining the ingredients, side effects, level of customer service and scientific studies. Then we sorted through all kinds of user comments and feedback that is posted online. Finally, we summed up all of the facts and details we discovered to give you the crucial information you need.

What is Red Light Therapy?

First off, Red Light Therapy is a non-invasive treatment. The ingredients includes infrared light beams that penetrate the skin about 8-10 millimeters in depth. This professional treatment is claimed to help with signs of aging, skin inflammation, hyperpigmentation, eczema, joint pain, psoriasis, stretch marks, scarring, sun damage, wrinkles, acne and dryness. This therapy is also said to improve skin tone and firmness. A single session generally lasts 15-20 minutes. Often one to four sessions a week are encouraged. [1]

Just so you are aware, Red Light Therapy is regulated and approved by the FDA. These light beds are often found in common salons and spas. There are no known Red Light Therapy side effects. Furthermore, both women and men of all ages can benefit from this treatment, but read on…

Discouraging Customer Comments – “Concerning?”

According to our Research Editor, “There are quite a few discouraging customer remarks posted on the web for Red Light Therapy. In fact, many people have stated that this type of infrared treatment does nothing at all.”

One person stated, “Not a believer. Already had three sessions of Red Light Therapy. Did absolutely nothing for me.” [2]

On the other hand, some customers have seen results. For instance, one person reported, “Helps with broken capillaries and scars. I dig it so far.”

Another commented, “Doing six sessions for sun damage. Hope it works as I was told it does.”

Red Light Therapy Reviews – “No Real Weight-Loss?”

After researching Red Light Therapy bed before and after results, we could not find anything that connects this treatment to weight-loss. It appears that this type of treatment is mainly just for skin concerns. One customer said, “Not really for fat loss or anything like that. Some doctors claim is helps reduce cellulite, but I have seen no results so far. It’s been a few months now.”

However, a different person posted this, “Been trying this Red Light Therapy for my cellulite. I think it helps a little. Keeping my fingers crossed.” [3]

“Too soon to tell at this point. Doing this for skin firmness and anti-aging,” mentioned another.

Our research has shown if there is a specific part of a weight-loss treatment or diet program that is very concerning or burdensome (discouraging customer comments, no real weight-loss results, side effects) the probability of long-term success is low. Therefore if Red Light Therapy does lead to all sorts of negative user reviews, this could be a serious issue. [4]

The Science – “Is It Solid?”

First of all, we at DietSpotlight like to see some actual science that supports the product or treatment we’re looking into. As for Red Light Therapy, there are some clinical studies that back up this treatment’s claims. However, this professional infrared therapy is not boasted as an effective weight-loss option.

The Bottom Line – Does Red Light Therapy Work?

Now the moment you’ve been waiting for. Here is our bottom line on Red Light Skin Therapy. To start, we like that this infrared treatment is approved by the FDA. We also appreciate that it’s commonly available in many salons and spas. However, there does not appear to be any actual science that supports this therapy as an effective weight-loss option. Furthermore, we’re concerned about the discouraging customer comments we found online. [5]

If you’re interested in getting rid of some excess pounds, then we suggest you choose a weight-loss treatment or supplement that is backed by solid science, does not break your bank account and is supported by numerous user testimonials.

Among the best products we’ve seen this year is one called Dietspotlight Burn. It contains a powerful blend of four ingredients. Some of them are clinically tested and are shown to help spark metabolism and improve fat loss. We can’t find any discouraging user comments, and customer feedback online reveals people are seeing great results.

The makers of Dietspotlight Burn are so sure about their product they’re offering a Special Trial Offer, which is a positive sign.

What You Should Know Red Light Therapy

Red-Light Therapy is an infrared system that looks like a tanning bed with red lights. We found information on the beds listed on websites for tanning salons, not weight loss clinics or doctor’s offices. Red-light therapy is marketed as an anti-aging treatment. The lights, according to multiple descriptions we found online, burn 500 calories per session. With regular use, if that calorie burn is accurate, the dieter could burn up to 2,000 extra calories per week using the Red-Light Therapy table. Similarly, Lipo Laser uses low level lasers to eliminate stored fat by melting the tissue and burning them off post exercise.

We also found in formation on Quick Slim Lipo, which uses red LED lights to slim the body. The term weight loss solution is used multiple times on the site, but at no point does the information on the red-light therapy claim to reduce weight, just inches. And if you're looking to eliminate inches, Freeze Fat is an FDA approved liposuction treatment that reduces fat cells to create a slimming effect.

  • Infrared light table.

Product Features of Red Light Therapy

We are a little skeptical about red-light therapy weight loss. A few websites mention increased calorie burn and others do not mention calories, but they do mention losing inches with regular therapy. The red-light therapy sites that mention calorie burn do not offer before and after photos, but the Quick Slim Lipo website does offer photos of inches lost after using red-light therapy. We noticed the main photo the company uses to promote red-light therapy looks like two different models. If the two models are the same, the tape measure is placed on a different place on the stomach slightly higher than the first measurement. In the before photo the person holding the measuring tape places her finger behind the tape, adding length so it looks like the second measurement is shorter by about two inches. With weight loss, it can be a tricky factor for individuals. One alternative that resembles cryolypolisis, Zerona uses non invasive laser treatment to remove stubborn body fat.

Advantages of Red Light Therapy

  • Red-light therapy may have beneficial medical uses.
  • Available at tanning salons and weight loss clinics.
  • May be less expensive at tanning salons.

Disadvantages of Red Light Therapy

  • No clinical links to studies proving weight loss.
  • The before and after photos do not look accurate or realistic.
  • There are no testimonials or before and after photos via most tanning websites.
  • No support for the claims you will burn 500 extra calories.


The Red-Light Therapy processes we found look more like fad body reduction programs than real weight loss solutions. If the red-light therapy bed does burn an additional 500 calories per session; the answer to weight loss has been found. With a healthy diet, exercise and daily red-light therapy the dieter could lose weight quickly – but this is not likely to happen though diet and weight loss are two proven tools that lead to weight loss and cost nothing.

Red-Light Therapy uses a laser, that has been approved by the FDA, to treat certain skin conditions. There is no link to weight-loss.

Red Light Therapy Side Effects:

Red Light Therapy is a well-known procedure. The FDA considers it safe. However, not everyone has the same reaction to treatment. There are reports of some mild side effects.


A certain area of your skin becomes red. The only issue may be the color, or there may be accompanying abnormalities. It’s not uncommon for redness of your skin to occur simultaneously with blistering, bumps, swelling, and itching.

What causes redness?

There are many irritants that provoke skin redness. Being out unprotected in the sun can make your skin red, as can insect bites. Some of the most common conditions known to make your skin red are eczema, cellulitis, dermatitis, shingles, and heat rash. [1]


Skin flushing, also known as blushing, is when your upper body, face, or neck rapidly become red. You experience a warmth over those areas. It’s normal to blush when you’re embarrassed, shy, or nervous. It’s when you experience flushing for no apparent reason that there may be something going on with you health-wise.

What causes flushing?

There are many conditions that make your skin flush. One of the most prominent is rosacea, a condition that causes redness and swelling. Cushing’s disease, menopause, and carcinoid syndrome also lead to flushing. Ask your doctor for an evaluation if you begin to notice unexplained flushing.


You feel a deep discomfort on your skin. A burning sensation without the presence of an actual burn injury. The burning area may become red. It may be recurring. The burning stops and then comes back regularly.

What causes burning?

You may be suffering from illnesses that cause burning sensation: scleroderma, dermatomyositis, polymyositis. Even rheumatoid arthritis can cause burning sensation. [2] If you have a burning sensation on your skin, it may also be a consequence of smoking.


There are different kinds of headaches. Some are focused in one area of your head. Some affect the entire region. A headache may be no more than an uncomfortable feeling of tightening, or it can feel like knives piercing your head.

What causes headaches?

The majority of headaches are not cause for concern. They occur due to every-day stressors. Skipping meals, not getting enough sleep, and being out in the heat can make your head hurt. Stress is also a contributing factor. Certain medical conditions also lead to headache: high blood pressure, ear infection, and glaucoma. Most people who undergo Red Light Therapy report no issues. But everyone’s body is different. If you see side effects not listed here, mention them in our reviews.

Red Light Therapy Scientific Abstracts:

Infrared Light Beam

Participant group had been treated with infrared therapy. Those in the placebo group had identical units, with no power connection to the circuit board. Subjects had undergone 7 weekly sessions. There were a set of values recorded for baseline and six weekly. The principle measure of outcome had been amount of pain of the NRS (numerical rating scale). Overall pain was observed and noted, in addition to bending and rotating in alternating directions. The treatment group’s mean numerical rating scale scores dropped from 6.9 of 10 to 3 of 10 at the completion of the study. Placebo group’s mean NRS had dropped from 7.4 of 10 to 6 of 10. It was concluded that the infrared therapy unit showed positive effects in reducing chronic back pain with no negative effects reported. [1]

There is clinical excitement regarding laser lipolysis for cellulite reduction. Surgeons have pointed out vast improvements of cellulite following a laser lipolysis procedure. Laser, as well as light, devices are expected to advance in order to maximize patient safety as well as clinical efficacy. Devices being used currently are being studied to find additional purpose like cellulite treatment, facial sculpting, hyperhidrosis, and periorbital adipose tissue tightening. In the future, the expectations are more precise and accurate laser and light devices. [2]

Circumferences of the patients had been measured and baseline and post treatment results were compared. Diagnostic ultrasound measurements had been carried out in 12 subjects in order to evaluate the decrease in adipose tissue volume. In addition, a cutometer was utilized in order to assess skin tightening improvements. There was an observation of a slow and steady decline within subject circumferences from baseline to the 6th treatment. Overall shaping of the body came with improvements in skin tightening that had been extremely noticeable in the before and after clinical photos taken following treatment. Measurements of adipose tissue and skin firmness had correlated with the study data using a diagnostic US and cutometer. There had been, on average, a 29% decrease of thickness of the fat layer between baseline and the 1 month follow up exam. Average decrease in circumference of the abdomen, buttocks and thighs from baseline up until the 3 month exam was 1.4, 0.5, and 1.2 cm, respectively. 93% of the subjects in the study had demonstrated a 1–60 % alteration in fat layer thickness. Subjects had described both satisfaction and comfort from the treatment, and 97% of subjects had been satisfied with the results. High power radio frequency energy combined with infrared, mechanical massage and vacuum seem to be a useful and effective modality for decreasing circumference of the abdomen, buttocks and thighs, with improvements to skin appearance and tightening.

  i have this therapy very Good
jenn (Verified User)

Had “laser lipo red therapy and it does work


Hi Jenn, did you continue? Did you see a difference in your body?


Hi Jenn, can you tell me more? It seems like a lot of money and sort of a gimmick. I went for one session via groupon but have not decided yet to continue.

  Does it really shrink fat?

   really have no positive opinion
Cori (Verified User)

I have my second session tommorrow and really have no positive opinion yet. I purchase a 6 session groupon and will have a better decision after my third visit.


I did i-Lipo with a Groupon last summer. Loved it. Of course I also made some other healthy changes. But I have tried the healthy changes before with no results. The i-Lipo gave me results. My pants started fitting better with just a couple sessions.


Cory, what were your results? Did you continue?


I received red light therapy at a mall spa that has now gone out of business. It produced full blown vitiligo. I lost almost all my pigment on my stomach and back and upper legs and arms as well as a wide patch on my forehead and neck. If anyone in your family has vitiligo, be weary. I had NO signs or symptoms beforehand. By the time it showed up, it was too late. My doctor was alarmed by the dramatic change in my skin.


I was scheduled for 6 treatments on my abdomen only since that is the only place I have fat. I followed all of the after treatment instructions. After 5 treatments, there was absolutely no sign of my abdomen getting any smaller. In fact, my pants felt tighter without any weight gain. I declined the last treatment. It was a total failure.

  It worked for me !
Kris (Verified User)

It worked for me. Loved it.


Do NOT, repeat do NOT use red light therapy for any reason! After 3weeks use, baby fine hair started growing on my face – I had never had any visible hair on my face before, I’m 61 years old. In addition, many of these baby fine hairs failed to surface and became ingrown turning into what looked similar to cystic acne. Now my face is scarred and I’m forced to undergo hair removal in an attempt to stop the cysts. Disastrous and embarrassing.

  This emulsifies fat cells
Anonymous (Verified User)

Red Light Therapy does not burn calories, it emulsifies fat cells. If you burn 350 calories with exercise or Whole Body Vibration Machine after the Red Light Treatment it sends the emulsified fat throught the limpatic system. (estimated between 40% – 62%)


I am thinking of trying just wonder ehst a session is like?
