Should I get Botox on my jawline before it's too late? I'm worried about the effectiveness.

Lately, I'm so stressed because my frown lines and square jaw stand out especially well whenever I look in the mirror or take photos. I hear others get regular Botox as part of their basic skincare routine, but I haven't been able to try it even once yet because I'm scared of potential side effects.

Everyone around me has been strongly recommending getting Botox while I'm still young to prevent wrinkles from settling in. However, now that I'm actually about to get it, I'm worried that my facial muscles might feel unnaturally immobile or that my cheeks might look hollow. I've just had the clinic appointment window open for days, agonizing over it. Are there any ladies out there who have consistently gotten Botox? Please let me know if my look looks natural afterward and if it's worth continuing to get it regularly.
