Cellulaze is a minimally invasive laser treatment designed to reduce the appearance of cellulite. Cleared by the FDA in January 2012, it uses a small laser fiber inserted beneath the skin to target the structural causes of cellulite dimpling. It remains one of the few treatments that works from the inside out, addressing the connective tissue bands, fat, and skin thickness that together create that characteristic puckered look.
How Cellulaze Works
Cellulite isn’t just about excess fat. It forms when tough fibrous bands running between your skin and muscle pull downward on the skin’s surface, while pockets of fat push upward in between those bands. The result is the dimpled, uneven texture most people recognize on thighs, buttocks, and hips.
Cellulaze targets all three layers involved. A tiny laser fiber (using a 1440 nm wavelength) is threaded through a small incision just beneath the skin. The laser’s thermal energy severs the fibrous bands that pull the skin downward, liquefies small pockets of fat that bulge between those bands, and heats the underside of the skin to stimulate thickening and tightening over time. By addressing the problem from underneath rather than from the surface, it treats the structural anatomy of cellulite rather than just temporarily smoothing it.
What the Procedure Looks Like
Cellulaze is performed under local anesthesia, meaning you’re awake but the treatment area is numbed. Your surgeon injects the anesthetic directly into the targeted zones before making a few very small incisions, typically just a few millimeters long. The laser fiber is then inserted through these openings and guided beneath the skin. Most cellulite treatments in this category take roughly 30 to 90 minutes depending on how many areas are being treated.
Because it’s minimally invasive rather than a full surgery, it’s usually done in an outpatient setting. You go home the same day.
Recovery and Downtime
Most people return to normal activities within a day or two. That said, recovery involves wearing a compression garment over the treated area for about six weeks afterward. The garment helps control swelling and supports the skin as it heals and tightens.
Common side effects include bruising and swelling in the treatment area, along with small amounts of fluid leaking from the incision sites. Less common but possible complications include infection, blood or fluid accumulating under the skin (which may need to be drained), changes in sensation, and scarring. Significant complications from cellulite treatments are infrequent overall.
How Long Results Last
One of the main selling points of Cellulaze is that a single treatment can produce results lasting up to three years. Results aren’t immediate, though. Because part of the effect depends on your skin thickening and remodeling in response to the laser energy, the full improvement develops gradually over several months. Some patients notice changes within weeks, but the best results typically appear around three to six months post-treatment.
Results can vary depending on your skin quality, the severity of your cellulite, and lifestyle factors like weight fluctuations. Cellulaze reduces cellulite but doesn’t eliminate it permanently, and some patients may see dimpling return over time as aging and gravity continue to affect the skin.
Who Is a Good Candidate
Cellulaze works best for people with mild to moderate cellulite who are near a stable, healthy weight. It’s not a weight loss procedure or a substitute for liposuction. If you have significant loose skin or very deep, widespread cellulite, the improvement may be limited.
Good skin elasticity helps, since part of the treatment relies on the skin’s ability to tighten and remodel after the laser stimulates it. People with very thin or very lax skin may not see the same degree of improvement. A consultation with a board-certified surgeon is the standard way to determine if your particular cellulite pattern is a good match for the procedure.
How Cellulaze Compares to Other Treatments
Several treatments target cellulite by severing those fibrous bands, but they use different methods to get there. Cellfina uses a tiny blade to mechanically cut the bands through a needle-sized device. Older techniques use a cannula to manually break them apart. Qwo, an injectable that was briefly on the market, worked by loosening the bands chemically using enzymes rather than cutting them (though it has since been discontinued).
Cellulaze is distinct in using thermal laser energy to sever the bands while simultaneously addressing the fat layer and skin thickness. This three-target approach is what differentiates it from treatments that only release the bands without affecting the skin itself. The tradeoff is that Cellulaze is more invasive than surface-level devices or injectables, requiring incisions and local anesthesia.
Topical creams and massage-based devices, by comparison, work only on the skin’s surface and generally produce temporary, modest results at best. They don’t reach the structural causes underneath.
Cost
The national average cost for Cellulaze is around $4,425, but the actual price varies widely. Patients report paying anywhere from $1,700 to over $6,000 for a single treatment area. The range depends on geographic location, the surgeon’s experience, how many areas are treated, and the extent of the work needed. Because it’s considered cosmetic, insurance does not cover it.
