I wear glasses and have bad habits that make me think about getting wrinkle Botox. It should be effective, right?

I have a habit of unconsciously scrunching my nose when wearing glasses or sunglasses at work, which is probably why a faint vertical mark has formed between the bridge of my nose and my eyes. It isn't very noticeable when I just leave it alone, but when I take off my glasses and look in the mirror, a distorted mark remains only in that area. Since it bothers me every time, I am looking into wrinkle Botox specifically for the nose area that targets facial muscles. I am hesitant about getting it injected on the bridge of the nose because I worry that if it is injected incorrectly, my facial expressions might look awkward or my nose might not scrunch properly, making it look strange. For those who have gotten wrinkle Botox for marks on the bridge of the nose or between the eyes, I am curious if it really effectively corrects the habit of scrunching when wearing glasses. Also, I would appreciate it if you could share your actual experiences regarding the level of bruising or pain you experienced when getting wrinkle Botox on the bridge of the nose.
