Which areas are effective for wrinkle Botox?

I’m worried because whenever I look in the mirror, fine lines that I didn’t really care about before are starting to catch my eye one by one. I am particularly concerned about the wrinkles that appear when I make facial expressions, so I am looking into wrinkle Botox. I understand that wrinkle Botox is administered to various areas, such as the forehead, between the eyebrows, and around the eyes, so I am curious if the treatment method differs depending on the location. Since this is my first time, I prefer a result where I can maintain my natural expressions while feeling slightly less self-conscious about my wrinkles, rather than a drastically noticeable change. That is why I am looking for experiences from people who have received wrinkle Botox. I am curious about the treatment duration and cost, as well as how often people typically get it done. I am also wondering if there was any discomfort in daily life after the procedure. If anyone has received wrinkle Botox, please share which areas you were most satisfied with and what points you discussed during your consultation.
