Chin Botox is something I get regularly, so I don't really have anything particular to say... But compared with the factory-style clinic I used to go to, they were much kinder and performed the procedure more carefully, so that was nice. I guess even factory-style clinics are all different in their own way.
I heard alar Botox was extremely painful, but it was more bearable than I expected (I did tear up). I saw the effect starting the next day. It looked the prettiest around weeks 1-2. My nostril shape was fixed into a narrow shape rather than a round one, so even when my nostrils flared, they didn't open beyond a certain point. But after 2 weeks it gradually wore off, and now that it's been about two months, there's no trace of it left. It was pretty for a short while, but I wonder what the point is, so I don't think I'll do it again.
