I'm looking up Botox reviews. How long does the effect usually last?

I have recently become interested in facial contouring, so I have been looking up a lot of Botox reviews. However, while reading the reviews, I noticed that opinions regarding the duration of the effects vary greatly. Some people say the effects last about three months, while others say they last nearly six months, so I am feeling confused.

For someone considering Botox for the first time, the duration of the effect seems to be a quite important factor. I would like to know in advance how often I need maintenance if I get the procedure. I’ve heard that getting Botox consistently makes the effects last longer, and I’m curious if that is actually true.

Also, when reading Botox reviews, I see some people saying their satisfaction increased after the second or third treatment compared to the first. I would like to know the reason for this as well. I am curious whether it is simply a matter of adaptation or if the muscle size itself changes.

As I am considering Botox, I would like to hear firsthand reviews from those who have actually used it. Please share what you were most satisfied with after receiving the injection, as well as what differed from your expectations. I would like to learn more about Botox before making a decision.
