Will Botox be effective for wrinkles as well as between the eyebrows?

I'm looking into Botox treatments for the wrinkles between my eyebrows, but I realized there are more types than I thought and a lot of things to pay attention to.

They say that even if they aren't very noticeable normally, vertical wrinkles can form between the eyebrows when you furrow your brows or make a facial expression while concentrating.

After hearing that if these wrinkles persist, marks can remain even without making facial expressions, I became curious about how to manage them in advance.

I’ve looked into it and heard that wrinkle Botox works by temporarily reducing the movement of the muscles used for facial expressions to alleviate wrinkles. I would like to know if it helps not only with existing wrinkles but also with preventing wrinkles that will deepen in the future!

Can I expect sufficient wrinkle Botox effects even in areas with frequent facial expressions, such as the space between the eyebrows? 

I am also wondering how to determine the best timing for the procedure if the wrinkles are not yet deep.

Also, since the area between the eyebrows is close to the eyes, I heard that the shape of the eyebrows may change or the eyelids may feel heavy after the procedure.

I want to reduce wrinkles while maintaining a natural facial expression. What should I check during the consultation regarding this?

I have heard that when considering wrinkle Botox treatment for the first time, the dosage and injection site are also important.

I am curious if the effectiveness of the same procedure varies because the movement of the muscles between the eyebrows differs from person to person.

How long does it usually take for the effects to appear, and how long does the maintenance last? recognition I would like to know. I am also curious about how to determine the appropriate interval if I receive the procedure repeatedly.

I would appreciate your advice on what I should prioritize when considering wrinkle Botox treatment, as my frown lines are not severe!
