What Is Zerona?

Zerona is a cold laser treatment approved by the Food and Drug Administration (FDA) for fat reduction in the waist, arms, back, hips and thighs.

The Zerona laser emits low-level laser energy that stimulates the fat cell, liquefying the fat within. This liquid fat moves from inside the cell to outside, where it moves into the interstitial space (or tissue space) until your lymphatic system clears it. Results are typically seen after about six treatments lasting 40 minutes each over a span of two weeks. Inches disappear from the waist, hips and thighs — the prime trouble spots where Zerona reportedly works best. It can also be used on other body parts with localized fat deposits that are resistant to diet and exercise. The technique works well for subcutaneous fat just below the skin.

Preparing for Zerona Body-Slimming Laser Treatment

It is important to commit to the protocol during the duration of treatment. This includes staying well hydrated by drinking half your body weight in ounces of water per day, (ex. 160lb. person should drink 80oz.), following a healthy diet, exercising moderately (ex. walking 30 min./day) and minimizing alcohol or caffeine.

The Zerona Procedure

A typical Zerona package includes six treatments. Each session takes 40 minutes. During the treatment session, you relax on a comfortable table. The laser is positioned over the body areas to be treated. The laser light is pointed to the front of your body for 20 minutes and then to the back of your body for another 20 minutes.

You won't feel anything. Zerona allows you to continue daily activities without interuption.
