Hello and thank you for your question! The success (or otherwise) of RF treatments are largely dependent on the person performing the treatment rather than the device itself! That being said, there are ways to reduce bulk with RF devices when desired. The risk of accidental volume loss with Sylfirm X is generally lower than with more aggressive RF devices, as it primarily focuses on tightening and improving skin quality rather than aggressively heating fat layers. However, excessive or overly aggressive treatment settings, particularly in individuals with already thin skin or low facial fat, could still contribute to some fat loss over multiple sessions. If volume loss is a concern, it's best to work with an experienced provider who can customize the treatment settings based on your specific skin type and goals. Best of luck!
