I'm curious who I should recommend Botox to.

Hello~!^^
Lately, I've been worried because fine lines between my eyebrows and on my forehead stand out whenever I look in the mirror. They seem fine normally, but when I take photos, the wrinkles look much deeper and my face seems tired. So, I'm thinking about getting Botox for the first time, but after looking into it, I'm confused about the difference between it and fillers. Since my face doesn't really lack volume yet, I feel like Botox might be a better fit than fillers, but I'm worried about making the wrong choice. If anyone has had Botox, I'd like to know who it is best suited for. I'm also curious if wrinkles are naturally reduced after the procedure, and I would appreciate it if you could explain the differences in characteristics between Botox and fillers.
