I'm curious about the effects of wrinkle Botox (considering my first procedure)

I am becoming increasingly self-conscious about the expression lines around my eyes and between my eyebrows, so I am seriously looking into getting a procedure.

According to my acquaintances, it is easy to manage,

I would like to know objectively how significant the actual wrinkle Botox effect is.

It is commonly said to temporarily reduce wrinkles,

I am also worried that my facial expression might look too unnatural after the procedure.

I am curious about how long the wrinkle Botox effect typically lasts if I get it regularly. I would also like to know if the most noticeable effect after the initial treatment is limited to specific areas such as the eyes or forehead.

Please also explain any precautions I should take before and after the procedure.
