I'm not sure whether to choose Botox or fillers...

hello

I am asking this question because I have a lot of trouble deciding whether to choose Botox or fillers.

I'm curious about the difference between Botox and fillers. I understand that they are among the more popular and common procedures, but I've lived without paying much attention to them, so I'm quite ignorant about them.

I would appreciate it if you could explain in what cases fillers and Botox are administered respectively, and what the major differences are.

And what is the approximate amount?

In my case, I have no fat on my cheeks, so my face looks long. What kind of procedure would be suitable for this situation?

Also, I look older because of the nasolabial folds and sagging under my eyes. It is a relief that I don't have many wrinkles, but if I were to get treatment for these three things—sagging under the eyes, nasolabial folds, and cheek fat—which procedure should I try?
