Types of forehead and cheek fillers and approximate CC count

Hello, I am an office worker who is concerned because my forehead and cheeks look sunken as I have lost a lot of weight in my face recently. Every time I look in the mirror, I look tired and older than my age, so I am writing this inquiry to inquire about getting filler treatment.

I really dislike anything that looks artificial, so I am extremely worried that my forehead might look unnaturally puffy after the procedure or feel very foreign to the touch. I would like to know which type of filler—domestic or imported—you generally recommend to achieve a natural-looking volume that fits my face shape and appears barely noticeable. I would also appreciate it if you could let me know approximately how much the duration of the effect varies between the different products.

I would also like to know, at least roughly, how many cc of filler is typically used on average when having both the forehead and cheeks treated, as I am doing. Of course, this varies depending on each person's face shape, but I think knowing the standard volume in advance would make the consultation much easier.
