I'm considering getting Botox. What is the satisfaction level like? I'm curious if it really works!

Lately, whenever I look in the mirror, because of the significantly increased wrinkles and the prominent square jaw

I'm one of those people who is stressed out.

I've tried home care and massages on my own, but,
Actually, I found that there are limits to self-care for muscles or deepening wrinkles.

I'm debating whether a procedure is the only solution in the end,
Even though Botox is so popular, I have a lot of concerns now that I'm actually about to get it.

I am thinking about getting a square jaw or work on the area between my eyebrows and my forehead this time.
For those of you who have recently received Botox treatment, how satisfied are you?

Will I see noticeable changes a few days after getting Botox?

I wonder if it's okay to get a light injection at a so-called factory-style hospital.
Or I'm wondering if I should look for a place that is more expensive but provides a bit more attentive care.
