I would like to inquire about Botox for deepened frown lines caused by my unconscious habit of furrowing my brows!

Hello! I have a bad habit of furrowing my brows deeply whenever I focus on a monitor or even unconsciously. In the past, the wrinkles would disappear quickly after I relaxed, but lately, fine horizontal and vertical lines are starting to form between my eyebrows even when I'm not looking, and it's really stressing me out. I'm constantly told that I look angry or tired, so I'm thinking of getting Botox before the lines get deeper! I'm wondering how long it usually takes for the effects to appear after getting frown line Botox at Maypure, and what is the safest and best interval to get injections without developing resistance. It would also be very helpful if you could let me know about the pain of the injection and any potential side effects after the procedure!
