Does following the precautions after getting Botox really have a big impact on the results?

While researching Botox, I've been seeing a lot of talk saying that aftercare is more important than the procedure itself.

I'm wondering how strictly I need to follow the precautions after getting Botox...

I've heard that I shouldn't lie down right after Botox, and that I should avoid exercise and saunas, so I'm a little worried...?

I would also like to know if it is okay to go about my daily life as usual after getting Botox, or if I should be careful for a few days.

I am curious about what specific things I need to pay attention to to maintain the effects of Botox for a long time, and I am also interested to hear from those with experience about the significant difference between when post-treatment care is done well and when it is not. Is there anyone who would like to share their experiences?
