The Emerald laser is an FDA-cleared green laser that helps your body release stored fat and lose inches, with no surgery, needles, or downtime. It's made by Erchonia, which reports earning the first FDA clearance ever given to a low-level laser. Below, you'll learn how the Emerald laser works and what "FDA-cleared" really means. You'll also see how Erchonia's FX-405 pain laser is related, and whether this treatment fits you at Dr. César Lara's Tampa Bay clinics.

What is the Emerald laser?
The Emerald laser is a low-level laser system that uses ten green light beams to shrink stubborn fat on the waist, hips, thighs, and other areas (Erchonia product listing). Its FDA clearance covers non-invasive reduction of body circumference in people with a BMI up to 40 (FDA record). Sessions are painless, and you can go right back to your day.
That BMI range matters. Some body contouring devices are cleared only for people closer to their goal weight, while Emerald was studied and cleared for a much wider range of bodies.
Why does Erchonia's track record matter?
A fat loss laser is only as trustworthy as the research behind it. Erchonia, a family-owned company founded in 1996, reports more than 20 FDA 510(k) clearances. Its first, in 2002, was so new that the FDA created a new device category for it (Erchonia press release via ODT).
| Year | Erchonia FDA clearance | Why it matters |
|---|---|---|
| 2002 | First clearance for any low-level laser (neck and shoulder pain) | Opened the door for medical lasers |
| 2004 | Add-on to liposuction for recovery pain | First post-surgical use |
| 2010 | Zerona: waist, hips, and thighs | Non-surgical slimming, no liposuction required |
| 2014 | Waist, hips, and upper abdomen for BMI 30 to 40 | Extended care to people living with obesity |
| 2019 | Whole-body chronic pain; first violet laser cleared for pain | Groundwork for the FX-405 |
| 2019 | Emerald laser: body circumference, BMI up to 40 | Today's flagship fat loss laser |
| 2021 | Postoperative pain | Expanded surgical recovery use |
Many of these clearances rest on placebo-controlled trials, the kind of evidence that matters if you like to check the research before you trust a treatment.
How does the Emerald laser release fat without destroying fat cells?
According to Erchonia, green light opens a tiny, temporary pore in each targeted fat cell. Stored fat slips out, and your body either burns it for energy or clears it through the lymphatic system. Dr. Lara has written that these pores close within about 72 hours, leaving a smaller, healthier cell behind.
That's a real difference from treatments that freeze or destroy fat cells. Fat tissue is part of your hormone system, helping manage appetite and metabolism. Dr. Lara describes this as turning overstuffed, unhealthy fat cells back into healthy ones, rather than destroying them. Our article on chronic inflammation explains why that matters beyond inches.
What results are realistic? Erchonia reports an average loss of about 6 inches across treated areas (Erchonia product listing). Clinical trials cited by Dr. Lara's practice showed an average of 4 inches in two weeks, and many patients trim about 6 inches in four weeks. Individual results vary.
FDA-cleared vs. FDA-approved: what's the difference?
FDA clearance means the FDA has reviewed a medical device through the 510(k) process and allowed it to be sold for a specific use. Approval is a different pathway, mostly for drugs and higher-risk devices.
"Specific" is the key word. An FDA-cleared fat loss laser like Emerald is cleared for body circumference reduction, and Erchonia's pain lasers are cleared for pain. One clearance doesn't carry over to the other use.
Where the FX-405 fits in
Erchonia also makes the FX-405, Emerald's sister technology. It combines red and violet light, and Erchonia's lasers hold FDA pain clearances that include low back pain, neck and shoulder pain, plantar fasciitis, and post-surgical pain.
To be clear, the FX-405 is a pain and recovery laser, not a fat loss device. Some patients use both. They contour stubborn areas with Emerald and ease knee or back pain with the FX-405, so exercise feels possible again. Our article on red laser therapy after surgery covers the FX-405 in more detail.
Is Emerald laser fat loss right for you?
Laser fat loss works best as part of a bigger plan. At both Dr. Lara clinics, in St. Petersburg and Palm Harbor, the Emerald laser is offered through the Formnovélle green laser body sculpting program, which pairs laser sessions with nutrition support.
Formnovélle is designed for people with less than about 30 pounds to release. If you have more, Dr. Lara typically suggests starting with the AWAKENING 12-Week Program and adding laser sessions for areas that hold on. Patricia combined the program with 12 green laser treatments and lost 13 inches from her thighs.
Skeptical? So was Dr. Lara. In a TV interview, he said he doubted the laser when he first saw it at an obesity medicine conference, until he read the studies. A board-certified obesity medicine specialist with 30+ years in practice doesn't adopt new technology lightly.

Tampa Bay has plenty of body contouring choices. Dr. Lara's clinics pair an FDA-cleared laser with a board-certified obesity medicine physician. Tampa Bay Magazine readers have voted Dr. Lara's practice the best weight loss clinic for more than 15 years.
