I'm curious about the duration of filler effects.

I am curious about the duration of fillers. I received my first filler injections in my nose and cheeks last month, but I can feel the volume gradually decreasing, so I am considering a re-treatment. Does the duration of hyaluronic acid fillers vary by area?

I tend to use my facial expressions a lot and exercise frequently, so I'm worried the effect won't last even six months. For those who have actually had it done, when do people usually get it refilled? Is there a difference in duration between the initial injection and a re-treatment? I've heard that getting it done too often can cause the skin to sag or the effects to wear off, so I'm a bit hesitant. I'd also like to hear tips on maintaining the results and advice on lifestyle habits. It would also be great if you could let me know the differences in duration depending on the type of filler (such as Leicester, Juvederm, etc.).
