What is the treatment cycle for frown lines Botox?

I have a bad habit of frowning intensely without even realizing it whenever I work in front of a computer monitor. ㅠㅠ This morning, after washing my face and looking in the mirror, I saw a deep wrinkle etched between my eyebrows in the shape of the Chinese character '川' (cheon), and I almost screamed. My foundation always settles into crease whenever I apply makeup, making me look so old, so immediately Botox I'm planning to make an appointment first lol. Since it's my first time getting injections in my face, I'm super worried about potential side effects, like my eyes feeling heavy or my facial expressions looking unnatural ㅠㅠ Usually, to get wrinkles completely smoothed out... Botox I'm also curious about the appropriate interval for consistent treatments after the first session to ensure good results! For wrinkles between the eyebrows deepened due to a habit of frowning, like mine. Botox If any of you have seen great results, I would be really grateful if you could leave lots of tips and feedback before you go lol
