I would like to know about wrinkle botox to prevent fine wrinkles.

Lately, when I make facial expressions, fine wrinkles are starting to appear between my eyebrows and around my eyes.
Before deep wrinkles form, I would like to take care of them in advance through wrinkle botox treatment as a preventative measure.
I'm curious about the effects of Botox, commonly known as a cosmetic procedure, and especially how effective it is at preventing fine lines and improving fine wrinkles that already exist.

I heard that Botox works by temporarily paralyzing muscle movement and thus inhibiting the formation of wrinkles. I wonder if it will bring about positive changes in the area of ​​fine wrinkles.

The areas I'd like to focus on are the forehead and around the eyes. I'm curious about how long the effects of Botox injections in these areas typically last, and whether getting regular treatments before the effects wear off will help prevent wrinkles.

I would also like to hear a professional opinion on whether starting Botox treatment at too early an age could lead to side effects such as developing resistance or weakening muscles later on.
