I would like to inquire about fillers, their benefits, and costs.

My face looks sunken overall, so I am looking into fillers. First, I would like to know what the benefits are. I understand that fillers are a procedure that restores volume, but I would like to know which areas they are commonly injected into and whether natural-looking changes are possible. I have heard that their role differs from Botox, so I need a consultation to determine if fillers are more suitable for the areas of concern I have.

I am also curious whether fillers are noticeable immediately after the procedure and how long the effects are expected to last. Since costs seem to vary significantly depending on the area, I would also like to know what budget I should set aside when starting. Could you recommend a treatment plan that suits my facial condition, considering the benefits and costs of fillers?
