For the 40K fat burner/cavitation head, we usually recommend using it 2–3 times per week on the same area, with at least 48 hours between sessions. Each session can be around 10–15 minutes per treatment area, and we do not recommend staying too long on one spot. Please keep the probe moving during use and always use gel or a water-based medium. For RF tightening heads, you can also start with 5–10 minutes per area, depending on your skin sensitivity. Start from a low level first and gradually increase only if it feels comfortable. 

Everyone’s skin sensitivity is different, and I use it myself all the time. When using it with the gel, I recommend starting at a low setting and gradually increasing the intensity until you find a level that feels comfortable for you. 

The RF head generates heat; if you require a higher thermal intensity, you can increase the energy level. 

No problem. The LED photon therapy is only an additional skincare feature. The main slimming and tightening effects come from the ultrasonic cavitation and RF functions, so the device can still work effectively even without LED therapy. 

Cavitation probes should not be used on the face. If you want to tighten facial skin, we recommend using HIFU (Hi-Fusion Therapy). 

Olive oil is not an essential oil. Each probe must be used with a suitable product. Essential oils, lotions, creams, and gels are all acceptable. Do not dry-heat the probe.
