I am curious about the effects and treatment cycle of wrinkle Botox.

I have noticed distinct wrinkles forming between my eyebrows and on my forehead whenever I make facial expressions, so I am looking into ways to manage them. They aren't very noticeable in my daily life, but they stand out particularly prominently in photos, which is bothering me. I am considering getting wrinkle Botox, but since it is my first time, I am most curious about the effectiveness and the treatment interval. I would also like to know if changes appear immediately after the procedure or if it takes a few days to see the effects. I am also curious if the cost varies by area, such as the forehead or between the eyebrows. I do not want a result where my facial expressions look too stiff, so I would like to consult about whether the treatment can look natural. I am also curious if the duration of the effects varies from person to person, and how the interval between treatments is determined. For those who have actually experienced this, please let me know which areas you had the treatment on and what the pain or discomfort was like. I would also like to hear about your satisfaction level after the wrinkle Botox procedure.
