Thank you for your thoughtful question! You're absolutely right that allowing recovery time between treatments is important. The suggested 2–3 sessions per week is general guidance, not necessarily the optimal frequency for every treatment mode. For **80K ultrasonic cavitation**, we recommend starting with **once a week per treatment area**, allowing approximately 7 days between sessions. RF, vacuum, and EMS may have different recommended schedules depending on the settings and your skin's response. More frequent treatments do not necessarily mean better results. Giving your body adequate recovery time is always important.
