The Science Behind Zerona’s Cold Laser Technology

Most fat loss lasers rely on freezing or burning fat cells, causing them to die. However, Zerona uses low-level laser treatment technology that emulsifies, or liquefies, fat. Four separate studies were performed to confirm the efficacy of this technique. These treatments do not harm fat cells like other treatments typically do, which is healthier for your body.

With both scanning electron microscopy (SEM) and transmission electron microscopy (TEM), the adipose, or fatty tissue was analyzed during the Zerona procedure. These devices acquired images that revealed how adipose arrangements collapsed after laser treatment.

Enlarged subcutaneous fat regions cause problematic sections of body fat, which are created by large fat cells, or adipocytes. Zerona’s laser technology induces these cells to form a transitory pore in their membrane. Through this pore, fatty material seeps out into extracellular space, which is regulated by the lymphatic system. As fatty material is evacuated, fat cells shrink, allowing fat loss from the treated area.


If you hope to lose weight or stubborn areas of fat that you just can’t seem to get rid of, you may have considered traditional weight loss surgery. However, surgery is not without its risks, including unsightly scars and lengthy recovery periods. Plus, some people don’t qualify for traditional weight loss surgery.

Zerona laser treatment doesn’t come with the risks or side effects of other methods. In fact, you can enjoy many benefits with this FDA Market-Cleared, industry-leading procedure, such as the fact that it’s:

  • Completely non-invasive

  • Completed in a relaxing treatment atmosphere

  • Able to provide effective results

  • Scarless & Bruiseless

  • Causes no side effects

You’ll remain awake throughout this entire non-surgical treatment, and afterward, you can continue your day without any downtime for healing.

Laser treatment may sound intimidating. However, Zerona-Z6 laser technology is able to target fat cells externally, no intrusive surgery required. Once treatment is complete, you’ll see no signs that you even underwent Zerona treatment apart from the missing inches from your waistline and a massive boost of confidence about how you look.

How Are Zerona and CoolSculpting Similar?

In some ways, Zerona and CoolSculpting, are similar cosmetic procedures. Both treatments are above-the-skin body contouring procedures that target body fat that’s proven difficult to remove through traditional methods like diet and exercise. Both are good alternatives to more invasive surgical procedures such as liposuction. The procedures for both treatments involve no incisions or anesthesia, a relatively short appointment for each treatment and have minimal or no downtime for recovery.

Zerona and CoolSculpting both work best for those who are relatively fit already and should be used in conjunction with a healthy diet and exercise plan. Clients of both procedures should be prepared to maintain their results through healthier lifestyle plans after their treatment. Both men and women can benefit from Zerona or CoolSculpting.

Neither procedure should be used to treat the severely overweight or obese, and should not be a replacement for a healthy, active lifestyle.

Both Zerona and CoolSculpting have been clinically tested. Both treatments give similar results for clients in terms of a slimmer body and reduced body fat in the targeted area.

CoolSculpting vs. Zerona: How Are Zerona and CoolSculpting Different?

While the Zerona and CoolSculpting procedures are similar in some ways, there are some key differences. The biggest difference is in the way that each method gets rid of body fat.

Zerona uses cold laser technology, or low-level laser technology (LLLT), in which a group of six lasers is aimed at the target area of the body to shrink fat cells. The lasers disrupt the membranes of the fat cells to emulsify fatty tissue and make the cells smaller. In this treatment, the fat cells lose tissue and shrink, but they do not die. The cells can keep contributing to healthy bodily functions. Clients are not able to feel the lasers penetrating the fat cells, they can simply lay there and relax.

In the CoolSculpting procedure, a device is used on the target area of the body to apply both suction and freezing cold temperatures. The device freezes and crystallizes fat cells, killing them in the process. Either radio waves or massage are then used on the area to break up the crystallized cells so that the body can flush out the dead cells naturally. Clients can expect to feel sensations of pulling, tugging, mild pinching, intense cold, tingling, stinging, aching, and cramping at the treatment site.

Aside from the treatment process, the overall cost and number of treatments can vary with each treatment. Coolsculpting costs between $2,000 and $4,000 depending on what area you treat and how many treatments are needed whereas it generally costs between $1,200 and $1,600 for 6 Zerona treatments depending on the provider. Additionally, Zerona is FDA-Cleared to treat the overall body whereas Coolsculpting is cleared to treat visible fat bulges under the chin, under the jawline, thigh, abdomen and flank, bra fat, back fat, underneath the buttocks and upper arm. A practitioner can help determine your treatment plan for either procedure when you are evaluating the pros and cons of CoolSculpting versus laser fat loss with Zerona Z6.

Which Treatment Is Right for Me?

Many of us have areas of stubborn fat we’d like to take care of. When diet plans and exercising just aren’t working out, or if you don’t have time to devote to longer workouts and complicated meal planning, it may be time to look into alternative treatments.

If you think body contouring treatments may be right for you, first assess your health and motivations. Are you relatively fit, with just a few problem areas of fat you want gone? Are you willing to keep up a healthy lifestyle to maintain the results of the treatments? If the answer to both of these questions is yes, a treatment like Zerona or CoolSculpting could be right for you. If you are severely overweight or have underlying health issues, consult with a doctor first.

Once you’ve decided to use body contouring treatments, how do you choose between Zerona and CoolSculpting? You should weigh the pros and cons of CoolSculpting and the pros and cons of Zerona to determine which procedure makes sense. There are some key differences that might make one better than the other for you.

  • Is there downtime? Each of these procedures can be done over a lunch period, but Zerona can be expected with absolutely no downtime.

  • When Will You See Results? It may take several sessions over weeks or months to see the results you want. Depending on the body area you want to target, CoolSculpting may take fewer sessions than Zerona.

  • How are results measured? Another factor to consider when choosing a treatment is the way that the results are measured. CoolSculpting measures clients’ results in terms of percentage of body fat lost, typically around 20% of the total body fat in the area being targeted. Zerona measures clients’ results based on overall inches lost. After completing six sessions, Zerona clients in the clinical test study lost an average of 3.72 inches. While individual results can vary with both treatments, choose the treatment program that aligns more closely with your personal fat loss goals.

  • What happens to the fat cells? The way that each treatment works on fat cells may also be a consideration. The CoolSculpting procedure uses freezing temperatures to freeze and kill the targeted fat cells. These frozen cells eventually disintegrate and the body excretes them through normal bodily processes over the course of about two months, getting rid of these cells forever.

However, consider the fact that fat cells play an important role in normal body functioning and overall health, so you may not want to get rid of them completely. Adipose tissue, another term for fat cells, is vital to the body’s endocrine system in producing hormones, as well as storing and releasing energy. The hormones released by adipose tissue are responsible for metabolizing sex hormones, regulating glucose and cholesterol, sending messages between cells and playing a role in blood clotting and blood pressure regulation. Fat cells help the liver and endocrine system regulate hormones and metabolism, so you may want to think twice before getting rid of these cells completely.

Because adipose tissue is so critical to hormone regulation, it can play an important part in so many bodily functions that keep us healthy. The Zerona procedure doesn’t kill off these essential cells. Instead, Zerona shrinks them down to a smaller size so you get the slimmer look you want without losing these crucial helpers of the endocrine system. Zerona gets rid of fatty tissue in the fat cells, but leaves the cells themselves intact so they can keep on contributing to the endocrine system. When the fat cells shrink down, they become the healthier, leaner cells they should be to function properly in the body.

If you want to keep those cells around and still achieve a leaner, slimmer body, Zerona might be the right choice for you. Zerona is an excellent option for anyone — man or woman — looking to shed fat and inches and regain their figure and confidence.

Zerona Consulation

In your one-on-one consultation, you will learn more about you and your health habits, goals, and expectations, so that they may tailor a treatment plan to meet your needs. The number of treatments you can expect in your treatment package will vary based on your individual needs and goals. Depending on your provider, your treatments may also be combined with supplements and nutritional recommendations, and “before” pictures and measurements of specific areas of the body to make the most of your results.

This varies from provider to provider, but since the lasers open your fat pores and exit through your lymphatic system, the healthier your lifestyle during treatment, the more drastic your results will be.


Once you finish your treatment package, your provider will take your final measurements to see how many inches you lost! They may also take your “after” picture, so that you can see your results side-by-side. Since the Zerona Z6 laser helps you lose actual fat and not water weight, results are permanent as long as you stick to a calorie neutral diet proceeding the treatments.
