I would like to inquire about the effects of male Botox!

Hello, I am a man in my 30s interested in Botox. I have a lot of wrinkles, especially around my eyes, so I am debating whether it would be a good idea to get Botox in advance. I am also worried that my face might look stiff or unnatural after the injection. Have any of you had Botox injections and shared similar concerns? I am also curious about the effectiveness and satisfaction levels you experienced. In addition to wrinkle improvement, I have a slightly square jaw; I would appreciate any advice you can freely give me on whether getting treatment on the jaw area would be effective in this case. I always thought of this as something that only happened to other people, but now that I am getting older, I feel a strong need to take thorough care of myself, so I am writing this post.
