Filler Inquiry

I received filler injections in my temples and cheek hollows a year and a half or earlier, and since then, they have remained unchanged due to factors such as weight gain.
I am currently on a diet, and two days ago, I received a 'high-power' radio frequency treatment on my face for a short period of time.

After the procedure, my cheekbones appear more prominent and my cheeks suddenly feel sunken, so I am concerned that the filler may have shrunk or melted.

Whether the change is a temporary phenomenon, or whether the filler can actually be broken down by the high-frequency procedure

Or maybe it's because I've lost weight (but for that, I've gained 4kg since the filler procedure: +6kg -> -2kg).

Please provide a response.
