Zerona functions with a low-level laser therapy which was tested as a safe and non-invasive replacement for liposuction. But in contrast to other non-intrusive procedures, the cold laser devices in Zerona will not cause cell tissues to warm up which can be very uncomfortable for the patient.

The cold laser treatment technology used in Zerona is proven to liquefy fat that will then be extracted from fat cells producing a minimized cell dimensions. The method will not cause discoloration, swelling and damage to other body cells. The therapy requires no sedation and will cause no discomfort, allowing patients to assume normal activities right after each treatment.
