I'm considering getting Botox for my frown lines. Has anyone had it done?

I'm looking into frown line Botox because vertical wrinkles appear between my eyebrows whenever I make a facial expression. I've noticed that more people get the procedure than I expected, so I'm curious about the actual satisfaction levels.

Is there a significant difference in effectiveness between domestic and imported Botox? I am curious if there are differences in terms of duration, naturalness, and resistance. I would also like to know if the difference in effectiveness is proportional to the price difference.

I am also curious about the typical interval between glabellar Botox injections and the recommended frequency. Since this is my first time getting it, I am worried about potential side effects, such as becoming too expressionless or having heavy eyes.

I would appreciate it if those who have personally received the procedure could share reviews, recommended brands, duration, and cost range for reference.
