It seems like the lines between my eyebrows have deepened since I entered my 40s. How should I go about getting a Botox consultation?

Lately, I’ve been getting quite worried because whenever I look in the mirror, the expression lines between my eyebrows and on my forehead seem to have become more distinct. I took a selfie with my phone while waiting at a traffic light while driving, and it was much more noticeable than usual. I’m in my early 40s, and I never thought I would get wrinkles like this already. Whenever I make a face, deep vertical lines form between my eyebrows, and horizontal wrinkles tend to appear on my forehead as well.

I have heard a lot about how effective Botox is, but now that I am actually about to get it, I have more than a few questions. I would like to ask if getting injections in both the glabella and the forehead makes my facial expressions look unnatural, and how long the effects last. Perhaps because I drive frequently, I seem to have a habit of furrowing my brows, so I am wondering if these habitual wrinkles can also be improved with Botox.

People around me have advised that it is better to start naturally with a small dose rather than getting a large amount at once. I would also like to know if the dosage is determined based on my skin condition and wrinkle depth during the consultation. Additionally, I would like to know in advance if I can resume my daily activities or drive immediately after the procedure, as well as if there are any precautions I should take on the day. As I am in my 40s and considering Botox for the first time, I am being cautious, so I would appreciate advice from those with experience.
