I am curious about satisfaction levels after filler treatment, the duration of the effects, and the treatment frequency!

I am considering filler injections because my sunken cheeks and deep nasolabial folds make me look tired. I am planning to get them because I heard that simply adding natural volume can make one look much brighter, but I am curious about the actual satisfaction level after the procedure. I heard that the biggest advantage of fillers is that they create natural symmetry that looks like your own face without looking artificial; are you really satisfied with the results?

I would like to know if I feel any foreign body sensation after the procedure, and how long the filler typically lasts. Which maintains the shape better, domestic or imported products, and what is the optimal interval between treatments? I am also curious if swelling or bruising is severe, and if it is possible to return to daily life immediately. If those with extensive experience with fillers have any firsthand reviews or precautions, please share them!
