I'm considering getting Botox. What is the treatment cycle?

Lately, I've been concerned that the muscles between my eyebrows and along my jawline have become more developed, making my impression look a bit harsh. Even after trying massages and stretching on my own, the muscles don't loosen up well, so I'm considering getting a procedure to help. Many of my acquaintances have also recommended Botox, so I am looking into it.

For those who have actually received Botox treatments, I am curious to know when you typically started noticing the effects. I would also like to know the recommended visit frequency to maintain a slim or smooth figure.

If anyone has experience with Botox, it would be a great help if you could share any pain, side effects, or your honest reviews!
