I'm planning to get Botox for my forehead and wrinkles.

I'm planning to get Botox on my forehead... will my facial expressions become awkward or difficult to make?

It is so stressful because as I get older, I can see the wrinkles on my forehead getting deeper due to my habit of frowning.

I hate seeing foundation settle into my wrinkles every time I apply makeup, so I’ve booked an appointment to get Botox this weekend.

I’ve heard from people around me that if forehead Botox is injected incorrectly, it can make your eyelids feel heavy or give you a fierce look, so I’m suddenly getting really scared. I’m wondering if it actually happens frequently that my eyes look awkward when I smile or open them wide, or if I get a feeling that my eyelids are being pressed down (like ptosis). Please also let me know how many units are usually needed for a natural look, and if it really doesn't hurt if I apply numbing cream!

It would be a huge help if those who have received this frequently or have experience with the procedure could share their honest tips or precautions.
