Thank you for your question! We understand the confusion. While 1MHz RF is often associated with deeper tissue heating, **3MHz RF is not limited to facial treatments**. The treatment depth also depends on the electrode design, spacing, and energy settings. Our FREYARA 13-in-1 is listed as operating at **3MHz RF** and includes a **6-pole RF head designed for body treatments**, as well as other heads for different treatment areas. So, you do not necessarily need 1MHz RF for body treatments. We hope this helps clarify the difference!
