Is the satisfaction level high if I get Belotero injections for fine lines around the mouth and nasolabial folds?

As I get older, putting aside the fact that my face is losing weight, the fine lines around my mouth and nasolabial folds just won't go away whenever I make a facial expression. Perhaps because of the loss of elasticity, the lines feel straight even when I'm not moving, so I look older every time I look in the mirror, and it really upsets me. I decided to post this concern to participate in a community event and to hear other members' opinions.

People around me have highly recommended Belotero filler for these fine expression lines, saying it looks natural, adheres well, and feels less like a foreign body. I heard that since it is an imported filler, it is a bit more expensive than domestic ones, but I am considering it very positively because I heard it has the advantages of having fewer side effects like the Tyndall effect and injecting evenly into thin skin layers. I am curious to know how satisfied those who have actually received Belotero injections for their nasolabial folds or around their mouths are.

Although I understand that the procedure is quick and allows for immediate return to daily life, I would like to know if the pain during the injection is bearable, and approximately how many months the Belotero effect lasts after a single injection. Please share any tips on how to schedule touch-ups on time to ensure the money isn't wasted. It would also be a great help if you could feel free to leave a detailed review in the comments regarding your satisfaction with the cost-effectiveness.
