How do you schedule and manage your Botox treatments?

Lately, looking in the mirror, I've noticed expression lines starting to form on my forehead, so I'm thinking about getting some care. They aren't deeply etched yet, but I think it would be good to start managing them proactively, so I'm looking into various options. However, I'm confused because opinions on the treatment frequency vary from person to person. Some say getting it too often isn't good, while others say they get it again before the effects wear off. I want to receive treatments that help maintain a natural-looking expression. For those of you who have received Botox regularly, how often do you usually get treatments? I'm curious about when the effects first appear, and I want to know if the duration of the results varies significantly from person to person. I would like to hear about actual care methods from those with experience with Botox.
