I'm thinking of getting Botox for the first time. Which area should I start on to get a natural-looking result?

I was taking pictures with my friends and got a bit shocked when I looked at my facial expression lol. I usually don't pay much attention to it, but when I smile, wrinkles really set in around my eyes, and the lines on my forehead are more visible than I thought ㅠㅠ

It isn't deeply indented yet, so it looks fine without makeup, but it definitely shows when I make big facial expressions. That's why I've been looking into getting Botox lately.

The problem is that since it's my first time, I don't know where to start, haha. I've noticed that some people start with their forehead, while many others get the space between their eyebrows or around their eyes done as well.

I absolutely hate having my facial expression look too stiff, so I think I would be satisfied if I just had fewer wrinkles than I do now.

For those of you receiving Botox for the first time, did you start with just one area? Or were you recommended multiple areas together based on your facial movements during the consultation?

It doesn't seem like the effects of Botox are visible immediately, so I'd like to know how many days it usually takes to notice a difference. Since there won't be much change at first, I feel like I'll just end up constantly looking in the mirror for no reason, haha.

I am also wondering if it is better to start with small areas rather than treating too many at once when getting Botox for the first time. Since having a natural facial expression is the most important thing, I want a slight softening effect rather than a strong tightening sensation.

If anyone has received natural-looking Botox, please let me know which areas you started with.

I'm also curious if you heard comments from those around you saying your face looked more relaxed or that your impression had changed after getting it haha. As someone looking to start Botox for the first time, please share your experiences regarding the effects and recommended areas!! :)
