What is Zerona?

First of all, Zerona is a non-invasive laser treatment [1]. This body contouring procedure resembles cryolypolisis [2] and supposedly helps remove excess body fat, without the side effects associated with liposuction [3]. Cold laser technology is used on the thighs, waist and hips. Each session takes about 40 minutes to complete.

Zerona [4] has been around since 2008. You can only receive treatment at an approved location. We like that we found some positive customer comments and that the company provides before and after photos, but read on…

High Price – “Can You Afford the Procedure?”

The first concern was the high price of Zerona treatments [5]. “The cost of is $1,500 to $1,700 for the cryolypolis treatments,” said our Research Editor. “Considering some insurance plans may not cover the price, the out-of-pocket expense could run into the tens of thousands.”

One customer stated, “I spend about $2,800.00 for 3 months of treatment for my son. The worst thing is that my son is still overweight [6] and after this treatment he refuses to try other products.”

“Cost me about $2,000 for six sessions, and I’m not seeing any results!,” said another person.

According to some Zerona reviews, price for the clinical fat loss treatment wasn’t a concern.

“I lost some weight without surgery. This alone justifies the price,” reported a dieter.

Customer Complaints about Zerona – “Concerning?”

There were multiple customers that weren’t pleased with Zerona. One commented, “I am doing Zerona at a reputable clinic. 4th treatment and nothing has happened, literally! I had a waist of 28 inches and it still is 28 inches.”

Another user said, “It’s been 2 weeks and NO results in inches and No results in weight loss.”

While results vary by person, we did locate some users that shared their positive experiences using Zerona.

“I’m 4 treatments into a 6 treatment plan of Zerona, and I’m pretty happy with the results so far. Looking forward to the next couple of weeks,” stated a dieter.

“I signed up for 9 treatments, the first one today. It was nice and relaxing,” reported another.

Our research has revealed that if there is a particular part of a weight-loss treatment that’s problematic, such as being the cause of customer complaints, the likelihood of long-term success is rather low. If users aren’t happy with Zerona, aren’t advised to exercise for fat loss [7] or they think body contouring [8] is the same as losing weight, there could be significant issues.

The Science – “Solid Research?”

Zerona has been reviewed and approved by the Food and Drug Administration (FDA). There have been clinical trials [9] [10] showing positive outcomes, including reduction in the circumference of the treatment area. The fact that this laser treatment works is a huge positive, but the cost can make the procedure impossible for many. Plus, there’s the fact that science doesn’t prove weight-loss either immediately after or weeks / months into the future. At DietSpotlight we are always on the lookout for proof from randomized research studies and this time it is easy to find.

What Users Are Saying

“There I was, running a gym and 30 pounds overweight. I felt like a hypocrite every day. As a former bodybuilder and MMA fighter, I knew what I had to do to get in shape but because of my age it just wasn’t working like it used to. It changed my life.”

“It’s painless and you feel nothing at all. There could be worse ways to drop a few pounds, yes?”

“I’m doing my 5th treatment of Zerona this coming Monday and don’t see any results. I’ve gained about 5-6 pounds since starting the program. I’m starting to wonder if this treatment is really worth the money. I still hope and pray that maybe in time things will change.”

The Bottom Line – Does Zerona Work?

So, should you spend your hard-earning money on Zerona? Well, we like that it’s non-invasive and an alternative to liposuction, but the research presented may not justify the high price tag. We’re also concerned about the customer complaints we found posted online.

If you’d like to drop more weight, then we suggest going with a product that’s backed by clinical research, but is also easy to use anywhere and will not break your bank account.

Among the best products we’ve seen this year is one called Burn HD. Its formula is a unique combination of four powerful ingredients, which have been shown in documented clinical research to help improve fat loss and boost metabolism. Also, we can’t find any talk of negative side effects and user comments around the web reveal people are seeing great results.

The makers of Burn HD are so confident in their product they’re offering a 2-Week Sample, which is a good sign.

Zerona Ingredients

Cold Laser Technology

Cold laser technology is a type of laser surgery mainly used by athletes and those suffering from some extreme pain symptoms. Using a light that emits a low wavelength frequency, it offers healing properties without overheating tissue cells to the point of damage.

What Is It Supposed To Do?

Recently, cold laser technology has broken free from its medicinal use and entered the cosmetic surgery sector. The companies that have started using this treatment claim that the fat in the cells are “liquefied” and ultimately cause weight-loss.

Clinical Research

According to a study published in Aesthetic Surgery Journal, “The cryolipolysis [cold laser technology] conformable-surface applicator was safe and efficacious for treatment of lateral thigh fat. Clinical photographs and ultrasound results showed significant reduction in fat thickness, and noticeable reduction in undesirable ‘saddlebag’ bulges.” Another study, published in Plastic and Reconstructive Surgery, confirmed its safety, saying, “Cryolipolysis [cold laser technology] is a promising procedure for nonsurgical fat reduction and body contouring and presents a compelling alternative to liposuction and other, more invasive methods.”

One study, published in Lasers in Surgery and Medicine, stated, “Although the mechanism of action for cryolipolysis [cold laser technology] is not yet completely understood, the efficacy and safety of this non-invasive procedure for fat layer reduction has been demonstrated in the studies available to data. Further studies will assist in identifying the mechanism and elucidate the full potential of this technology to perform safe, non-invasive fat reduction for areas of local fat accumulation.” [1]

Another study tested just how much fat was lost after treatment. Published in Lasers in Surgery and Medicine in 2014, researchers concluded, “Cryolipolysis [cold laser technology] is a safe, well-tolerated, and effective noninvasive fat removal methodology that on average leads to 39.6 cc [about .082 pounds] of fat loss of the treated flank at 2 months after a single treatment cycle.” [2]

One that’s caught our attention is Dietspotlight Burn. It contains clinically-tested ingredients and has been shown to promote weight-loss. Click above to read more about the sample offer.

Zerona Scientific Abstracts

Cold Laser Technology (Cryolipolysis)

Fat thickness reduction happens gradually over the initial 3 months of treatment and is most noticeable in individuals with limited and discrete bulges of fat. Bruising, temporary numbness and erythema of the skin occurring at the treatment site are the most commonly reported after treatment, although these effects are mostly resolved in around 1 week following treatment. There are no reports of scarring, alterations of blood lipid or liver function profiles, or ulceration to date. It was concluded that Cryolipolysis is a noninvasive treatment which could be beneficial in treating excess adipose tissue. [1]

Applying cold temperatures to a precise location causes apoptosis of the adipocytes, which in turn, triggers an inflammatory response that results in a slow digestion by surrounding macrophages. Studies have shown cryolipolysis to be paramount in reducing subcutaneous fat at the site of treatment by up to 25% following just one treatment. There had been improvements noticed in 86% of patients. The patient satisfaction rate was higher than any other noninvasive lipolysis technology at 73%. Cryolipolysis has proven itself to be an extremely safe treatment for contouring the body and can be carried out with very limited discomfort. The side effects are minimal, but include temporary erythema, short-lived numbness and bruising, which typically vanish within 14 days following the treatment. Although there isn’t a treatment which is considered the best regarding noninvasive body contouring, cryolipolysis is found to be extremely safe and efficient, boasting a very high satisfaction rate within patients.[2]

Cryolipolysis is a very promising treatment for noninvasive fat reduction and body contouring with great potential. Cryolipolysis delivers a great alternative to liposuction as well as other, more invasive, procedures. The method appears to be safe in the short-term, harnessing limited side effects, and significantly decreases fat when used for localized adiposities. It has yet to be made clear whether more than one treatment or post-treatment manual massage in the same areas improve efficacy of the procedure. [3]

Cryolipolysis has shown to be effective in both human and animal studies alike. Data confirms the method’s selective decreasing of fat in human and animal subjects, with further evidence of gradual thinning of the fat layer during a period of 2 to 4 months. Interestingly, cryolipolysis has not produced reports of adverse side effects in studies to date and any reported effects are temporary and minor. The mechanism of action for the cryolipolysis procedure has yet to be understood completely, but the effectiveness and the safety of this noninvasive therapy for fat reduction has been very well documented. There is a need for further studies which will assist in identifying said mechanisms and to clarify the full potential of this technology. [4]

What You Should Know About Zerona

Zerona is a laser liposuction surgery to remove excess body fat. The surgery is FDA approved and must be performed by a licensed physician. Unlike other forms of liposuction, Zerona does not bruise tissues under the skin, reducing recovery time. The official website for Zerona provides before and after photos of successful fat reduction. These photos do not depict spectacular changes in size. In some cases, bloat is reduced.

List of Ingredients - What's in Zerona?

Laser-aided non-invasive lipo.

Product Features

Despite being called a lipo procedure, Zerona does not break the skin. Red Light Therapy also does not break the skin either, by penetrating the skin with light beams to reverse the signs of aging, stretch marks, while improving skin tone and firmness. A laser heats fat cells causing them to collapse. The body naturally flushes the collapsed fat cells out of the body over time. Six sessions take place over a two-week period before results are noticed. Additional treatments may be scheduled as needed. Another procedure discovered to give the same results is Freeze Fat, which eliminates fat cells by a terminology referred as coolsculpting. A pro of this procedure it is approved by the FDA. With Zerona, there is no recovery time or bruising after the procedure, so all regular activities can resume after. Patients walk into the office and walk back out to continue daily activities as normal.

Zerona may help slim the look of the body, but there is no mention of weight loss in official literature. We did find testimonials from patients who lost three or four pounds after six or more sessions. Healthy eating and exercise are important because overeating after a series of Zerona treatments will lead to weight gain and the results will not last. As it relates to treatment, Lipo Laser uses low level lasers to remove stubborn fat stored in the body. An estimated growth has been seen with this alternative as it approved by the FDA and safer than liposuction.

Zerona only works on subcutaneous fat. Subcutaneous means under the skin. Visceral fat, located behind muscles closer to body organs, will not be affected by the treatment. So, dieters may have a slimmer waistline, but the effect will not improve health. Large amounts of visceral fat can lead to healthy issues and illness.

The total cost for Zerona treatments will differ from one doctor to the next. The typical cost of a series of treatments will be around $2,800. The treatments may reduce area size, but the results will only last if a healthy diet and exercise plan is adopted and maintained.

Zerona Advantages

  • FDA-approved treatment for fat loss.
  • Will reduce number of fat cells under the skin.
  • Non-invasive.
  • No bruising or cuts in the skin.
  • No time off work.

Zerona Disadvantages

  • Effects will only last with life changes.
  • Patients must reduce caloric intake and exercise regularly.
  • The cost is much higher than a weight loss program or proven fat burner.


Zerona is a viable option for the dieter with a bit of extra stubborn fat. It will not, however, help the dieter lose 10, 20, 30 or more pounds without diet or exercise. The effects of Zerona are dependent on dieting and exercise. Removing fat cells may temporarily reduce body weight, but fat cells can expand so eating an unhealthy diet means weight gain even if Zerona is successful.

    The cells are dissolved utilizing laser power. Vaser uses ultrasound technology to target the unwanted fat while still preserving surrounding muscle. Individuals will go to any or all lengths to achieve this.

        • Anonymous

          Zerona did work for me. I exercised 2X a week and followed instructions to drink a lot of water. This, however, worked against me. I drank too much water which depleted my body of Potassium. I blacked out. I dealing with some additional health problems. I lost 15 lbs.

        • Kim

          I started the zerona treatments on Monday. I’ve been doing everything they’ve asked of me. So far I’ve lost 1.5lbs and hoping to lose more. However, I’m not sure of the inches because they took measurements the first day the next two days they only took my weight. I will inform you all later if there is any progress in the future.

      • Liberty Redshoes

        Oh, sure, if you don’t mind spending over a grand to lose a half-inch off your waist . . . don’t waste your money. You will be disappointed and broke!

    • Glenn (Editor)

  •  already worked somewhat
    cindy (Verified User)

    i had one treatment and have been exercising 3 times a week. I seem to feel it has already worked somewhat. I have had a lot of hot flash sweating , I woke that . night soaked. I know the fat is broken up and released through sweat . Could this be part of this procedure. I don’t mind if it is , it’s working well if it is. Just wondering

    • Stephen (Editor)

      That’s interesting, Cindy, because they claim it is free of the usual harsh side effects. This sounds similar to the effects of a thermogenic. This could be. If you continue and find the discomfort grows too much for you please stop and ask sculpting technician what the causes may be.

      • Texas patient

        I did numerous treatments in 2011. Results were far above expectations. I lost many inches but paid a high price. I will never do it again. Spiked liver enzymes that never recovered. Now that test is done monthly and over twice the upper limit. I believe Zerona wrecked my liver. No liver problems before.

  • Apryl Mccrumb

    Laser therapy has additionally been proved noteworthy in elevating the levels of endorphin (like nicotine).

  • Michael

    Save your money. My wife and I went in and had six 40-minute sessions. We followed the requirements for drinking a gallon of water a day, 20 minutes of activity within 2 hours of a session, cut out sugars, etc…We did not lose any inches. I lost 6 lbs from 200 lbs. and my wife lost 3 lbs. I will guarantee you that you will lose this same weight if you do all the requirements with no laser treatments. The only true way to lose weight and inches is to exercise and diet daily while watching your meal portions and consume less calories than you burn. If you are extreme overweight, then go with real lipo and then start your diet and exercise plan from there if you need that jumpstart.

    • Glenn (Editor)

  • Lynn

    Worked for me. 6.34 inches one week after the last treatment. I measured at home too and came up with same number. Did it once a week, drank water, ate low carb/sugar, exercised very little. Going to do another 6. Had a groupon so only 500 for 6 sessions.

  •  Losing hope, that this will work !
    Lisa (Verified User)

    Well, I too went for their sales pitch, promises & photos. I’ve finished 6 treatments so far &nothing. No change at all. I measure myself at home as I’ve been on a weight loss/exercise plan since December & am monitoring my progress. I thought I’d give this to myself a s a treat for already losing 46 pounds instead of a tummy tuck. I too go t a very clean, reputable Medi-spa place here in Ocala, FL. I’ve done everything they said to do. Compression garments, no caffeine, water, etc. I already was exercising & watching my food intake so that was already in place. I signed up for 12 sessions in total – but I’m losing hope that this expensive treatment will really work…

  •  I feel like a fool !
    joy (Verified User)

    Left my stomach lumpy and cellulite looking. It was not like this whatsoever before zerona. I feel like a fool

  •  I was down by 1 1/2 inch !
    Victoria (Verified User)

    I’ve so far had three treatments and about 48 hours after the three one I checked my measurements and was down 1 1/2 inch. I must say I’m watching what I eat and I have exercised maybe twice within that week. I have six more treatments to go. And honestly I will take a inch and a half a week if thats all I can get out of it.

  •  Did not work for me
    Elizabeth (Verified User)

    I spent my bill money on this…it didn’t work…so sorry I was believing this would work…had to drive 30 miles for treatments…what a waste of time and money ..

  • Wish I had spent the money on lipo.

    It wasn’t worth the money or all the time. For $2,000 I lost 1 inch off my waist. Or did I? The lady could’ve just pulled the tape tighter. I felt like a schmuck for falling for the sales pitch. Wish I had spent the money on lipo.

    • Glenn (Editor)

      Hi T. A high price tag could definitely be a deal breaker. You may want to consider an affordable alternative like Dietspotlight Burn. Click above to read more about the sample offer.

  • bella

    I did six sessions of zerona, and followed up with body wrap session each time. made sure to walk everyday for 30 minutes and exercised 4x a week for an hour each time. I removed caffeine and sugar in drinks or sugary drinks and switched to stevia with caffeine free tea, cut down on bread, pasta and rice and including more healthy options and smaller portions. it’s been 2 weeks and NO results in inches and No results in weight loss. When they did the inches again (which btw i went ahead took pre and post at home and haven’t lost any), they tried to tighten it more to show i lost half an inch and i called them out on it. I kept track how how loose they took measurements to each area, so please watch out when it comes to that.

  •  It is very sad to see this. It does not work for my son.
    beata (Verified User)

    I spend about $2800.00 for 3 months treatment for my son.
    And I was promised results.
    First they asked him to drink a lot of water then he wasn’t loosing inches so they asked to stop drinking as much water then when treatment was finished they said sorry………
    I could have a nice all inclusive vacation with my husband instead of it.
    The worst thing is that my son is still overweigh and after this treatment he refuses to try other products……..
    It is very sad to see this.
    Zerona has a great advertisement and he was really hoping that this will help him.
    I also can’t get them out of their list so I am constantly reminded of my mistake.
    It is up to you to do this or not.

  •  Michael (Verified User)

    Doesn’t work
