Yes! The vacuum/suction function is **optional and does not have to be used**. The RF, 80K cavitation, and vacuum functions can be operated separately, so you can use the machine without suction. However, since you have lipedema, we recommend consulting your healthcare provider before using the RF or cavitation functions, especially on painful or sensitive areas. The machine is not designed to treat lipedema. Please stop using it if you experience pain, bruising, or increased swelling.
