I would like to inquire about the duration of glabellar Botox and the touch-up cycle.

Lately, I have noticed the space between my eyebrows becoming increasingly tense and the wrinkles seeming to deepen, so I am considering getting Botox. Since I tend to frown heavily when concentrating on work, I am worried that the wrinkles might become permanent. I am thinking of taking this opportunity to start managing my skin, so I am writing to inquire as I have a few questions.

1. How long does the effect usually last after a single injection of glabellar Botox? I know it varies from person to person, but I am curious about the average frequency. I have heard that to properly see the wrinkle-preventing effects, you need to get repeated injections around the time the effects start to wear off, so I would like to know how often it is best to visit.

2. Also, I plan to stop by briefly after work to get the procedure, and I am curious about the total duration from the consultation to the actual treatment. Since this is my first time trying Botox, I would like to thoroughly check for any potential side effects and precautions before visiting.
