Isavera Fat Freezing System Review

The Non-Invasive Fat Freeze Treatment - What You Need to Know

The Isavera fat freezing system is a home-based solution that aims to target and reduce fat cells in specific areas of the body through a process called cryolipolysis.

Cryolipolysis, also known as "fat freezing", is a non-invasive cosmetic procedure that utilizes controlled cooling to eliminate fat cells without causing damage to the surrounding tissue.

The Isavera system works by using a patent-pending Velcro neoprene belt and specially formulated gel packs that need to be chilled in the freezer prior to use.

The pre-chilled gel packs are inserted into the belt, which is then worn around the targeted area of the body, such as the waist, thighs, or arms.

This exposes the fat cells to freezing temperatures, causing them to crystallize and die off. The dead fat cells are then naturally flushed out of the body over time.

A Non-Invasive Approach

Essentially, the Isavera fat freezing system freezes unwanted fat cells in a process akin to freezing off a wart, just without any negative effects on the skin or other tissues.

This non-invasive approach provides an alternative to more invasive procedures like liposuction for reducing pockets of fat in specific areas that are resistant to diet and exercise.

While the Isavera fat freezing system aims to reduce fat cells and promote body contouring, it is important to keep in mind that it is not a weight loss treatment. The system works to target stubborn body fat in certain problem spots but does not necessarily lead to overall weight reduction.

To get the most out of the Isavera system, it is recommended to use it in conjunction with healthy eating habits and regular exercise.

How Does It Work?

The Isavera fat-freezing system works through a process called cryolipolysis. Cryolipolysis involves exposing fat cells to extremely cold temperatures to freeze and crystallize them.

When fat cells are frozen, they enter a state of programmed cell death. The frozen and dead fat cells are then naturally eliminated from the body as triglycerides.

This process of fat cell death and elimination is similar to how freezing off a wart works. However, unlike wart removal, using the Isavera fat-freezing system does not cause any negative effects on the skin or other tissues.

The controlled cooling is localized to the fat cells being targeted, leaving surrounding tissues unharmed.

How to Use the Isavera System

To use the Isavera fat freezing belt, the specialized gel packs provided need to be chilled in the freezer for at least 24 hours before use. Once fully frozen, the dual-action gel packs come pre-shaped to fit into the Isavera strap's respective pockets.

The neoprene vest or wrap is then worn around the desired area of treatment, such as the waist, arms, or thighs for a minimum of 60 minutes per session.

It is recommended to use the Isavera strap about 3 times per week over a period of 10-12 weeks to allow sufficient time for the complete elimination of the frozen fat cells. 

The adjustable wrap ensures the chilled gel packs remain in full contact with the skin, allowing the cold temperature to penetrate the tissue and reach the underlying fat cells. The freezing temperatures applied to the fat tissue trigger the process of cryolipolysis, thereby destroying and eliminating the fat cells in the treated area.

Potential Side Effects to Consider

The Isavera fat freezing system is considered to be generally safe when used correctly, with minimal side effects reported. However, there are some precautions and considerations to keep in mind.

Common side effects include numbness, bruising, and temporary redness that typically subsides within hours. Avoid using the Isavera system if pregnant, breastfeeding, or with certain medical conditions that affect body temperature regulation.

Discontinue use if you experience blistering, severe discomfort, or other adverse reactions, and consult a doctor. To minimize frostbite risk, ensure proper fitting of straps and exposure time of skin to gel packs.

It is important to consult with a licensed healthcare professional before using the Isavera fat-freezing system, especially if you have any pre-existing medical conditions. Your doctor can help determine if cryolipolysis is appropriate for you, and discuss any potential risks based on your health profile.

Isavera vs Other Brands

The Isavera fat freezing system offers a non-invasive alternative to more invasive surgical fat reduction methods like liposuction. Unlike liposuction, the Isavera system does not involve any incisions, anesthesia, or downtime for recovery.

However, the effectiveness and results of the Isavera system compared to professional fat-freezing procedures have not been scientifically proven. While some customers report noticeable fat reduction results, medical spa treatments like CoolSculpting may provide more dramatic and longer-lasting effects given the advanced cooling technology used.

At-home cryolipolysis devices like Isavera are more affordable and convenient compared to in-office treatments. But it is important to carefully consider individual needs and expectations when deciding between professional and at-home fat-freezing options.

Factors like the total area needing treatment, the severity of fat deposits, and desired results can help determine whether a product like Isavera is the right fit over medical spas or surgical procedures. Consulting with a doctor is recommended when making this assessment.

Overall, products like the Isavera system provide an accessible option for non-invasive fat reduction that may complement a healthy diet or other lifestyle changes. But customized evaluation of each person’s unique goals is important in deciding what fat elimination method is likely to work best.


Most users report seeing a 1 to 2-inch reduction in the circumference of treated areas like the stomach, thighs, arms, and back. However, more substantial body contouring results may require multiple Isavera kits. While localized fat reduction is possible, the Isavera system does not guarantee significant weight loss.

Focusing on a proper diet and exercise regimen during treatment can help optimize results. Periodic waist, belly, and hip measurements using a body fat caliper or measurement tape can track progress.


While some customers report noticeable reductions in fat mass, more intensive options like CoolSculpting generally offer a higher success rate. The Isavera system likely works best for those with localized fat deposits who desire an affordable method requiring minimal recovery time and movement restrictions.

What Our Clients Say About Us

  • "The treatment itself was not uncomfortable. Afterwords, I felt great. I didn't really notice anything for about 30 days. After day 30 until about a month later, I started noticing that my favorite jeans were not as tight anymore. I wasn't having to suck in to get them buttoned. And by that two month period after my CoolSculpting

  • "It's subtle at first, and then a month later you look and go, "Wow - It really did something!" It really moved the bar for me, and I'm feeling better about myself already. It feels so good to put on anything and know I look as good as I've ever looked. And I didn't say that or feel that when I was in my 20's, 30's, and 40's."
